COP16 BIODIVERSITY SUMMIT

COP16 ends with no agreement on funding roadmap for species protection


The biggest conference on nature conservation worldwide, COP16, came to a close on Saturday. But participants stopped short of making a decision on one of the biggest asks of the summit – agreeing on a detailed plan to increase funding for biodiversity.

The world's biggest nature conservation conference closed in Colombia on Saturday with no agreement on a roadmap to ramp up funding for species protection.

The 16th Conference of Parties (COP16) to the UN's Convention on Biological Diversity (CBD) was suspended by its president Susana Muhamad as negotiations ran almost 12 hours longer than planned and delegates started leaving to catch flights.

The exodus left the summit without a quorum for decision-making, but CBD spokesman David Ainsworth told AFP it will resume at a later date to consider outstanding issues.

The conference, the biggest meeting of its kind yet, with around 23,000 registered delegates, was tasked with assessing, and ramping up, progress toward an agreement reached in Canada two years ago to halt humankind's rapacious destruction of nature's bounty.

The Kunming-Montreal Global Biodiversity Framework that emerged from that meeting had set 23 targets to be met in just over five years from now.

They include placing 30 percent of land and sea areas under protection and 30 percent of degraded ecosystems under restoration by 2030, reducing pollution, and phasing out agricultural and other subsidies harmful to nature.

The Canada summit had also agreed that $200 billion per year be made available to protect biodiversity by 2030, including the transfer of $30 billion per year from rich to poor nations.

The actual total for 2022 was about $15 billion, according to the Organization for Economic Cooperation and Development (OECD).

On top of that, nations have pledged about $400 million to a Global Biodiversity Framework Fund (GBFF) created last year to meet the UN targets.

In Cali, negotiators were split largely between poor and rich country blocs as they haggled over increased funding and other commitments.

The biggest ask from the summit – to lay out a detailed funding plan – turned out to be a bridge too far.

Muhamad, Colombia's environment minister, had offered a draft text proposing the creation of a dedicated biodiversity fund, which was rejected by the European UnionSwitzerland and Japan.

Developing nations had insisted on the creation of a dedicated biodiversity fund, saying they are not adequately represented in existing mechanisms including the GBFF, which they say are also too onerous.
'Clock is ticking'

The meeting did manage to coalesce around the creation of a fund to share the profits of digitally sequenced genetic data taken from plants and animals with the communities they come from.

Such data, much of it from species found in poor countries, is notably used in medicines and cosmetics that can make their developers billions, very little of which ever trickles back down.

Delegates also approved the creation of a permanent body to represent the interests of Indigenous people under the UN's Convention on Biological Diversity.

Representatives of Indigenous peoples, many in traditional dress and headgear, broke out in cheers and chants as the agreement was gaveled through.

But the talks on biodiversity funding stumbled even as new research presented to coincide with COP16 showed that more than a quarter of assessed plants and animals are now at risk of extinction.

Only 17.6 percent of land and inland waters, and 8.4 percent of the ocean and coastal areas, are estimated to be protected and conserved.

UN chief Antonio Guterres, who had stopped over in Cali for two days with five heads of state and dozens of ministers to add impetus to the talks, reminded delegates that humanity has already altered three-quarters of Earth's land surface and two-thirds of its waters.

"The clock is ticking. The survival of our planet's biodiversity – and our own survival – are on the line," he said.

The meeting was held amid a massive security deployment following threats from a Colombian guerrilla group with its base of operations near Cali. No incidents were reported.

The world’s biggest nature protection conference agreed in Cali, Colombia on Friday to create a permanent body to represent the interests of Indigenous people under the UN’s biodiversity convention.

Representatives of Indigenous peoples, many in traditional dress and headgear, broke out in cheers and chants as 196 countries agreed on a “subsidiary body” dedicated to “matters of relevance to Indigenous peoples and local communities.”

It was the first major breakthrough for the 16th Conference of Parties (COP16) to the UN’s Convention on Biodiversity, which opened in Cali nearly two weeks ago and went deep into extra time Friday as delegates clashed on ways to raise funding for plans to preserve nature.

“This is an unprecedented moment in the history of multilateral agreements on the environment,” an overjoyed Camila Romero, an Indigenous representative from Chile, told delegates after the adoption at the summit, themed “Peace with Nature.”

“Parties have recognized the constant need for our full and effective participation, our knowledge and innovations, technology and traditional practices,” she added.

Delegates also agreed on a specific role for Afro-descendent communities in the new subsidiary body, though a number of details have yet to be ironed out.

Last-ditch effort to solve funding deadlock at nature-saving summit

Negotiators at the world’s biggest nature conservation conference knuckled down in Cali, Colombia on Friday for a last-ditch effort to break a deadlock on funding for efforts to “halt and reverse” species loss.

The Colombian presidency of the summit, which opened on October 21 and was programmed to run until Friday, proposed a raft of late-night draft texts on possible ways out of the stalemate.

With some 23,000 registered delegates, the 16th Conference of Parties (COP16) to the UN’s Convention on Biological Diversity is the biggest-ever meeting of its kind.

It is a follow-up to an agreement reached two years ago in Canada, the Kunming-Montreal Global Biodiversity Framework, which called for $200 billion per year to be made available to protect biodiversity by 2030.

Under the agreement, this was to include $20 billion per year going from rich to poor nations by 2025, and $30 billion by 2030.

The targets included placing 30 percent of land and sea areas under protection and 30 percent of degraded ecosystems under restoration, while reducing pollution and phasing out agricultural and other subsidies harmful to nature.

COP16 was tasked with assessing, and accelerating, progress.

But negotiations on funding have failed to advance, observers and delegates say, even as new research presented this week showed that more than a quarter of assessed plants and animals are now at risk of extinction.

Amid murmurs that the talks may drag into an extra day, the COP16 presidency proposed a compromise that would see talks continue after the summit — and until the next one in Armenia in 2026 — to find a “comprehensive financial solution to close the finance biodiversity gap.”

Such talks would also assess the viability of creating a new, dedicated biodiversity fund — a key demand from developing countries who say they are not represented in existing mechanisms, which are also too onerous.

– ‘Cali Fund’ –

Another point of contention at the summit is on how best to share the profits of digitally sequenced genetic data taken from animals and plants with the communities they come from.

Such data, much of it from species found in poor countries, is notably used in medicines and cosmetics that can make their developers billions.

COP15 in Montreal had agreed on the creation of a “multilateral mechanism” for sharing the benefits of digitally sequenced genetic information — abbreviated as DSI — “including a global fund.”

But negotiators still need to resolve such basic questions as who pays, how much, into which fund, and to whom the money should go.

In a draft text for negotiators, the COP16 presidency proposed creating a new “Cali Fund” for the equitable sharing of DSI benefits.

Negotiators also remain stuck on the nature of a mechanism for monitoring progress toward the UN goals.

– ‘Everyone has to cede’ –

On Thursday, COP16 president Susana Muhamad, Colombia’s environment minister, said the negotiations were “very complex,” with “many interests, many parties… and that means everyone has to cede something.”

UN chief Antonio Guterres, who stopped over in Cali for two days this week with five heads of state and dozens of ministers to add impetus to the talks, reminded delegates that humanity has already altered three-quarters of Earth’s land surface and two-thirds of its waters.

Urging negotiators to “accelerate” progress, he warned: “The clock is ticking. The survival of our planet’s biodiversity — and our own survival — are on the line.”

Representatives of Indigenous peoples and local communities held demonstrations at COP16 to press for more rights and protections as delegates inside wrangled over a proposal to create a permanent representative body for them under the Convention on Biological Diversity.

On this, too, no agreement has been reached after nearly two weeks of talks.

The meeting has been held amid a massive security deployment, following threats from a Colombian guerrilla group with a base near Cali.

The world’s biggest nature conservation conference enters its final day in Colombia Friday with negotiators at odds over how best to fund plans to “halt and reverse” species loss.

Amid murmurs that the talks may drag into an extra day, summit president Susana Muhamad said Friday’s programmed closing session promised to be “heart-stopping” given the number of unresolved issues.

“It’s a very complex negotiation, with many interests, many parties… and that means everyone has to cede something,” Muhamad, who is Colombia’s environment minister, told reporters Thursday.

With some 23,000 registered delegates, the 16th Conference of Parties (COP16) to the UN’s Convention on Biological Diversity (CBD) which opened in Cali on October 21, is the biggest meeting of its kind ever.

The event is a follow-up to the Kunming-Montreal Global Biodiversity Framework agreed upon in Canada two years ago, where it was decided that $200 billion per year must be made available for biodiversity by 2030.

This must include $20 billion per year going from rich to poor nations to reach 23 UN targets to “halt and reverse” nature destruction by 2030, and by placing 30 percent of land and sea areas under protection.

COP16 was tasked with assessing, and ramping up, progress towards the targets.

But negotiations on funding mechanisms have failed to progress, observers and delegates say, even as new research this week showed more than a quarter of assessed plants and animals are at risk of extinction.



– ‘Chance to act’ –



Developing countries have called for more money.

They also want a brand new fund under the umbrella of the UN biodiversity convention, where all parties — rich and poor — would have representation in decision-making.

Rich countries insist they are on track to meet their funding targets, and many are opposed to yet another new fund.

European officials pointed Thursday to deadly flooding in Spain as a reminder of the harm that comes from humans’ destruction of nature, and urged delegates at the deadlocked talks to “act.”

European Commission envoy Florika Fink-Hooijer said the “catastrophe” in eastern and southern Spain this week, with at least 158 people dead and dozens still missing, highlights the link between biodiversity destruction and human-caused climate change.

Droughts and flooding worsened by global warming cause the loss of plant species, including trees which absorb planet-warming carbon, in a vicious cycle of human-wrought Earth destruction.

“If we act on biodiversity, we at least can buffer some of the climate impacts,” Fink-Hooijer, who is the European Commission director-general for environment, told reporters.

“At this COP we really have a chance to act,” she added.



– ‘Clock is ticking’ –



Another point of contention among delegates is on how best to share the profits of digitally sequenced genetic data taken from animals and plants with the communities they come from.

Such data, much of it from species found in poor countries, is notably used in medicines and cosmetics that make their developers billions.

COP15 had agreed on the creation of a “multilateral mechanism” for benefit-sharing of digital information, “including a global fund.”

But negotiators still need to resolve such basic questions as who pays, how much, into which fund, and to whom the money should go.

UN chief Antonio Guterres, who stopped over in Cali for two days this week with five heads of state and dozens of government ministers to add impetus to the talks, reminded delegates Wednesday that humanity has already altered three-quarters of Earth’s land surface, and two-thirds of its waters.

Urging negotiators to “accelerate” progress, he warned: “The clock is ticking. The survival of our planet’s biodiversity — and our own survival — are on the line.”

Representatives of Indigenous peoples and local communities held demonstrations at COP16 to press for more rights and protections, as delegates inside wrangled over a proposal to create a permanent representative body for them under the CBD.

On this, too, no final agreement has been reached.

COP16 parties voted Thursday to have Armenia as the host for their next summit in 2026.

Layoffs in the technology sector reach a new high

As layoffs continue to shake the technology sector, a new report reveals the tech companies that have slashed the most jobs in 2024 so far. Data shows that in the UK, at least 6,036 employees in tech companies have lost their jobs since January.

The firm BestBrokers has aggregated data on layoff announcements from global gaming companies using TrueUp, an IT job portal, and Obsidian, a note-taking app that tracks gaming industry layoffs.

This showed that from January to October 18, 2024, more than 254,000 employees in the technology sector have been laid off, with more than half of all layoffs announced by U.S.-based companies while in the UK, 6,036 employees have been made redundant.

With 2,157 workers let go, London-based rapid grocery delivery startup Zapp tops the list of tech companies slashing the most jobs in the UK this year. Luxury fashion e-retailer Farfetch ranks second with roughly 2,000 employees being laid off following the acquisition by South Korean retailer Coupang.

The UK-based tech companies laying off the most employees this year are:Zapp – London, 2,157 layoffs
Farfetch – London, 2,000 layoffs
Ocado – Hatfield, 1,000 layoffs
Sumo Group – Sheffield, 250 layoffs
IHS Towers – London, 100 layoffs
SuperMassive Games – Guildford, Surrey, 90 layoffs
Sourceful – Manchester, 80 layoffs
XR Games – Leeds, 72 layoffs
nDreams – Farnborough, Hampshire, 44 layoffs
Healthy.io – London, 40 layoffs

Out of the 254,023 employees laid off globally in the tech sector this year, 144,332 have worked for companies based in the United States. South Korean tech companies are responsible for another 14,615 layoffs, followed by Chinese companies slashing 14,175 jobs.

Overall, since January 2024, the top 20 tech companies on our list have collectively laid off 150,327 employees. This figure represents more than half of all global tech job cuts, which total 254,023 so far this year.

Dell stands out for cutting the most tech jobs since the beginning of the year. After eliminating 6,000 positions in March, the company recently announced another round of cuts, shedding 12,500 employees, about 10 percent of its workforce, as part of a strategic shift toward AI-driven products and services.

Intel, the semiconductor giant based in California, ranks second with layoffs affecting more than 15 percent of its workforce or around 15,000 employees. This cost-cutting move, aimed at saving $10 billion by fiscal 2025, follows a disappointing earnings report for the April-June 2024 period.

U.S. retail giant Amazon ranks in third place with more than 14,900 layoffs announced since January. The company is reducing its global workforce from 105,770 to around 90,000 by eliminating mostly managerial positions in a move intended to save between $2.1 billion and $3.6 billion a year.

 

Landmark 20-year study of climate change impact on permafrost forests



Data could help rethink climate change models regarding sources of carbon and CO2 sinks

In perhaps the first long-term study of CO2 fluxes in northern forests growing on permafrost, an Osaka Metropolitan University-led research team has found that climate change increased not only the sources of carbon, but also the CO2 sinks.

The 20-year observation from 2003-2022 in the interior of Alaska showed that while CO2 sinks turned into sources during the first decade, the second decade showed a nearly 20% increase in CO2 sinks.

Graduate School of Agriculture Associate Professor Masahito Ueyama and colleagues found that warming led to wetness, which in turn aided the growth of black spruce trees. During photosynthesis, the growing trees were using the increasing CO2 released from human activities.

“The 20 years of observational data that we have is, as far as we know, the longest record of such research on permafrost forests in the world,” Professor Ueyama proclaimed. “However, since it is difficult to apply the findings and data from those 20 years to a future world in which warming continues, further long-term observations are needed. But we hope that our findings will help verify and improve the accuracy of warming prediction models.”

The findings are published in the Proceedings of the National Academy of Sciences.

Less car use and more plane travel: how energy consumption related to transport has changed since the pandemic



A study examines changes in mobility patterns in Europe during and after the pandemic




Universitat Oberta de Catalunya (UOC)





Living with a mask stuck to your face, only leaving the house to go to the supermarket, not using the bus or the commuter train... The COVID-19 pandemic triggered sudden and far-reaching social changes worldwide, not only because of measures to protect people against the virus but also as a result of the policies applied by governments to curb the spread of the virus and reduce the impact of the disease on the health system. Four and a half years have gone by since the WHO declared a health emergency and, thanks to vaccines, we have learned to live with the virus. While some changes have stayed with us, others have been quickly forgotten.

In recent years, many studies have sought to analyse the impact of these changes. Now, a research project led by Helena PatiƱo examines changes in energy consumption in the European transport sector during and after the pandemic. PatiƱo is a PhD student on the Society, Technology and Culture programme and member of the Sustainability, Management and Transport Research Group (SUMAT) in the Universitat Oberta de Catalunya (UOCFaculty of Economics and Business. She is being supervised by Professor Pere Suau, who also carried out research at the Universitat AutĆ²noma de Barcelona Institute of Environmental Science and Technology (ICTA-UAB). Their work has led to the recent publication of an article with Lewis C. King and IvĆ”n Savin, both researchers at ICTA-UAB.

The paper, available in open access, concludes that during the worst of the pandemic there were significant and widespread reductions in the use of motorized land transport, both individual and collective, and in the use of aviation. However, recovery patterns have been different across the continent. "Overall, Europeans have reduced car use since the pandemic, but have flown much more frequently. However, trends vary considerably between countries. Some have resumed previous transport patterns, while others have managed to maintain a moderate reduction in transport use," said PatiƱo.

 

Has the pandemic changed the way we get around?

Mobility is in the spotlight of all climate policies. As stated in the article, transport still relies heavily on fossil fuels, accounting for around 37% of emissions of human-generated carbon dioxide (CO2, the main greenhouse gas) worldwide. Strategies for reducing emissions, such as the European scheme for a 55% reduction by 2030, have one of their main areas of action in the transition towards low-emission mobility, with measures including the electrification of transport and the promotion of collective transport such as trains and buses. For all of them, a change in people's behaviour is essential.

The first two years of the pandemic provided a unique opportunity to study changes in people's travel habits. Travel decreased sharply with lockdowns and border closures but, after the relaxation of control measures, people did not completely return to their old habits. For example, as detailed in the paper, a survey in the United Kingdom found that Britons were willing to reduce the number of flights they took by 20-26% and car journeys by 24-30%. However, such data do not reflect in detail the extent to which the pandemic has changed mobility patterns in Europe.

"Achieving lasting changes in people's behaviour is not easy. Governments should support environmentally friendly transport options, such as bicycles and electric cars, and lead campaigns to change behaviour, so that sustainable transport is not just an option, but the preferred choice for everyone," said PatiƱo, who has also published an article in The Conversation Europe on this issue. "In the post-pandemic era, this could mean expanding the cycling infrastructure, making public transport more affordable, and supporting remote work and local outdoor activities."

 

An uneven recovery: lessons from Sweden, Denmark and the Czech Republic

Following the gradual lifting of pandemic restrictions, Europeans' transport habits have evolved unevenly. According to the study, in some countries, such as Austria, Germany and the United Kingdom, the use of planes and cars remained below normal after restrictions were lifted, but the changes weren't major. Other countries, where COVID-19 policies were stricter, like Greece, Portugal, Italy and Spain, experienced a notable rebound in flying and the use of land transport (road and rail). This increase, the researchers say, could also be influenced by the attractiveness of Mediterranean destinations for international tourists.

However, the study reveals that some of the changes that occurred during the pandemic have been maintained in three countries: Sweden, Denmark and the Czech Republic. "Sweden already had a relatively high percentage of remote workers before the pandemic, but the number has continued to grow since then. Furthermore, since 2010, the country has been promoting outdoor leisure activities, facilitating access to places of natural beauty and promoting outdoor exercise," PatiƱo added. "Denmark, in turn, has continued to invest in cycling infrastructure and electric bicycles. A recent survey found that Copenhagen residents are cycling to work more than before the pandemic."

In the Czech Republic, measures to reduce fares on public transport helped encourage cleaner transport options after restrictions were lifted. Getting around on foot has also gained popularity: the number of pedestrian journeys in Prague has increased by 10% since 2016. "The overall results indicate that there is unlikely to be a uniform change in behaviour towards less travel across Europe," PatiƱo said. "However, important lessons can be learned from countries that do show lasting effects, as their transport and energy policies may have contributed to these outcomes."

High survival rates explain 20 years of rapid expansion of wolves in Germany



The country sports the world's highest survival rates of wolves

Since wolves returned to Germany 20 years ago, they have spread quickly in many parts of the country. The rapid increase in the number of wolves was due to high survival and reproduction rates in areas with favourable environmental conditions. This is the result of an analysis carried out by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) in collaboration with the LUPUS Institute, the Federal Agency for Nature Conservation (BfN), and the Senckenberg Center for Wildlife Genetics. The probability of survival for wolves during the period analysed was higher than anywhere else in the world. However, the expansion phase will end as soon as the carrying capacity of suitable German landscapes are reached ­– at which point survival rates can be expected to fall, according to the scientific team in a new paper in the scientific journal Wildlife Biology.

Young wolves in Germany had an annual survival probability of 75 percent during the first two decades since the beginning of the recolonisation of Germany; for adult wolves it was as high as 88 percent. For young wolves up to the age of two years, the variation in survival rate depended on the suitability of the habitat ­– the less suitable it was for wolves, the lower their survival; for adult wolves, such a relationship could not be established by the scientific team led by the Department of Ecological Dynamics at the Leibniz-IZW. “Using survival analysis, we were able to determine the median survival time of a wolf in Germany to be 146 weeks, which is around three years”, says Prof Dr Stephanie Kramer-Schadt, head of the Leibniz-IZW department and professor at the Technische UniversitƤt Berlin. The highest recorded longevity of a wolf in the study dataset was almost 13 years.

“The survival rates of the German wolf population were very high compared to other regions, in fact they were among the highest in the world”, Kramer-Schadt continued. “This indicates that the wolves settled in habitats that were very suitable for them during the 20 years which we analysed in this paper. Strict legal protection has also contributed to high survival rates.” Landscapes that qualify as suitable are those that offer sufficient cover – for example by forest cover – and areas that are as far away from roads as possible. These areas allow wolves to avoid humans and can serve as refuge for the animals. If wolves settle in less suitable habitats, this reduces their survival and reproduction. “While adult animals can still survive and establish territories in less suitable areas, the lower survival rate of young and sub-adult wolves and the lower number of young per litter slows down population growth and thus the expansion of the species.” As soon as the optimal areas are occupied, the growth of the population will slow down, according to the scientists.

The scientific investigation was based on a long-term dataset provided by the Federal Documentation and Consultation Centre on Wolves in Germany (DBBW) and included the surveys and findings of the comprehensive wolf monitoring in the German Federal States. It furthermore considered the results from tens of thousands of DNA analyses by the Senckenberg Center for Wildlife Genetics, which made this scientific investigation possible in the first place. The team also determined the reproductive performance of a total of 201 breeding females from 165 territories which were part of the analysed long-term dataset from 2000 to 2020. “We were able to analyse data from those female wolves over the years, that had offspring – at on average for 2.8 years”, says IZW scientist and first author of the paper Dr Aimara Planillo. “The analyses also show higher reproductive success of females with more experience and in more suitable habitats, with up to five reproductive years.” Summarising, the models show that a well-suited habitat and the reproduction experience of the female have a positive effect also on litter size, which in Germany averages at least four offspring.

Similar scientific analyses in other countries and regions illustrate how high the survival rate for adult wolves in Germany actually is. Other non-hunted populations also have high adult wolf survival rates of 78 per cent in the USA or 82 per cent in the Alpine regions in central Europe, although these do not come close to the 88 per cent in Germany. The reason for this is that the German population is still expanding.

The Department of Ecological Dynamics at the Leibniz-IZW investigates (among other things) the population development of large carnivores such as the wolf or Eurasian lynx using individual-based, spatial models, ranging from analysing past processes – such as the recolonisation of Germany by the wolf – to predicting future developments. For the paper recently published in “Wildlife Biology”, the scientists used demographic data on the wolf population (age, sex, year and place of birth, dates and places of resighting as well as cause of death) from the years 2000 to 2020 and related them to environmental variables such as habitat suitability (accounts for the different land use types and human disturbance effects, e.g. forested areas, distance to roads or human density), wolf population density (annual density of wolf territories around the focal territory) and the season of the year.

A significant proportion of the data comes from the ongoing molecular genetic analysis of samples collected in the field, which are sent to Senckenberg as part of the wolf monitoring programme of the German Federal States. Based on the genetic profiles created, numerous wolf individuals are collected several times over the years and can be assigned to wolf packs by analysing their relatedness. The Leibniz-IZW team then developed spatio-statistical models to determine the influence of environmental variables on the probability of survival of the population, the annual survival rates of different age classes, the probability of reproduction and reproductive performance. This revealed how well a variable – such as high habitat quality – can predict each population parameter and how substantial its influence is on the number and spatial distribution of wolves in Germany.

Previous scientific investigations by the Leibniz-IZW showed that

  • the recolonisation of Germany by wolves is not a homogeneous, continuous process, but characterised by changing conditions. This means, for example, that wolves show different behaviours during different phases with regard to the suitability of habitats: In early phases, wolves liked “cherry-picking” when establishing new territories, while they were much less selective during later phases when the population was close to habitat saturation. The lower survival rate of young animals identified in the current paper and the lower number of offspring in less suitable areas provide an explanation for these preferences of wolves.

  • the wolf population in Germany is essentially healthy and that human-caused deaths such as traffic accidents and illegal killings are responsible for the overwhelming majority of wolves found dead. Data from the 1,000 wolves dissected at the Leibniz-IZW in Germany show that around three quarters of dead wolves die in traffic collisions – mostly with cars on country roads or motorways. In 13.5 per cent of all wolves examined, evidence of a criminal offence such as illegal gun wounds was found, although the animals did not always die as a result.

Temperature at Roque de los Muchachos Observatory rose 1.1 ĀŗC in 20 years, twice as much as predicted by climate models




Universitat Autonoma de Barcelona






The meteorological data recorded over the past two decades by sensors of the Roque de los Muchachos astronomical observatory facilities point to a rise of 1.1 ĀŗC in the average temperature. The analysis, led by UAB researchers, shows more than double the increase predicted by climate models for the same area, and even more than expected for the next 20 years.
Researchers from the Department of Physics of the Universitat AutĆ²noma de Barcelona led a long-term study of climatic conditions at one of the main astronomical observation sites in the northern hemisphere: the Roque de los Muchachos Observatory, on the island of La Palma. In an area located 200 metres below the ridge on which most of the optical telescopes such as the Gran Telescopio Canarias are located, are the MAGIC Telescopes, built to detect very high energy gamma-ray sources by a collaboration in which UAB researchers were also involved. It is also the site of the construction of the northern hemisphere’s Cherenkov Telescope Array Observatory (CTAO).
UAB researchers Markus Gaug and LluĆ­s Font analysed a unique series of meteorological data from the area recorded over a period of 20 years by the meteorological instruments installed on the roof of the MAGIC telescope control building. The weather station has sent data on temperature, relative humidity, atmospheric pressure and wind speed and direction every two seconds during all this time.
“The station was built with the intention to have some guidance for telescope operations, not to characterise local weather professionally, let alone the effects of climate change on the measured parameters,” explains Markus Gaug. But “the fact that they were relatively low-cost devices has been an advantage, since they had to be changed and recalibrated every two years or so, which has favoured the reliability of the data and greatly limited the effects of long-term sensor drifts, which are difficult to detect,” he adds.
The Spanish meteorological service, AEMET, did not install a professional station at Roque de los Muchachos until 2022. However, thanks to data from 36 other AEMET weather stations spread across the island of Tenerife, it has been possible to carry out studies of temperature variation in the Canary Islands for many years. Some studies show an increase of 0.3 ĀŗC per decade between 1970 and 2010. Other more recent studies had obtained an increase per decade of up to 0.25 ĀŗC in the same area with historical data up to 2014, and the models predicted between 2015 and 2050 a temperature increase of 0.3 to 0.5 ĀŗC per decade.
Based on data recorded since 2004 by the MAGIC telescopes, and using advanced statistical analysis, researchers from the UAB Department of Physics were able to very accurately determine the climate trends in this area. The experimental data obtained show an increase of 1.1 ĀŗC over the past 20 years, i.e. 0.55 ĀŗC per decade. This is more than double the increase predicted by climate models for the same area, and even more than expected for the next 20 years.
The results also show an increase in the diurnal temperature range, the difference between the highest and lowest temperatures during a 24-hour period, of 0.13 ĀŗC per decade, and also an increase in seasonal temperature oscillations of 0.29 ĀŗC per decade.
One of the most surprising data observed is the increase in average daily relative humidity of 4% per decade. This is an increase that was also observed in other studies at the Mauna Kea observatory on the island of Hawaii, and contrary to the decrease in humidity recorded at the other continental observatories. The researchers consider that a possible explanation for this difference between the island and continental observatories is the increase in seawater evaporation as a result of global warming.
Scientists monitored the variations in the climate at these sites after the scientific community expressed concerns about the impact of climate change on the viability and quality of data collected by unique observatories in the world, such as those at Roque de los Muchachos. In particular, the atmosphere of the subtropical zone of the Canary Islands is highly valued for astronomical observation as it is very stable throughout the year. The MAGIC telescopes are located above a thermal inversion layer with low pressures and excellent observing conditions with very dry and clean air.
Fortunately for the astronomers, the UAB study found no significant changes in the frequency of rainfall or, above all, in the occurrence of strong storms. In this sense, one of the data analysed by the researchers was the rate at which temperature may change, which has remained below variations of half a degree per minute in all measurements, a condition that meets the requirements for the proper functioning of the future Cherenkov Telescope Array Observatory (CTAO).
“At the moment, while using linear models, there is no evidence that the changes detected in the meteorological conditions could affect the operation of the telescopes or increase the time they will have to remain inactive due to inclement weather in the coming years, but these results are further evidence of the worrying pace of global warming”, says LluĆ­s Font. “In addition, we all know that after a certain temperature increase, the linearity of the climate system ends and that can lead us to the 'tipping points' where the climate changes its behaviour drastically”, adds Markus Gaug.
The research was published in the journal Monthly Notices of the Royal Astronomical Society. Led by researchers in the UAB Department of Physics Markus Gaug and LluĆ­s Font, also attached to the Centre for Space Studies and Research (CERES-IEEC) of the UAB, the study included the collaboration of IFAE scientists and several universities in Italy and Germany. The work is also co-authored by Sofia Almirante Castillo, who participated in the research with a final degree project in 2022, when she was a student at the UAB, under the direction of Markus Gaug.

The future of chimpanzees depends on smart conservation strategies and that requires data, lots of data. Ecologist Adrienne Chitayat conducted research on chimpanzees in Tanzania and is the first to systematically survey the population density in the entirety of Mahale Mountains National Park. In her dissertation, she provides a detailed baseline of the density of chimpanzees in the park, which is part of the Greater Mahale Ecosystem. Chitayat also developed a new, deep learning-based acoustic detector that can identify chimpanzee sounds. This technology allows chimpanzee populations to be monitored more efficiently and human-related threats to be more easily anticipated. Chitayat will defend her PhD on Thursday, 7 November, at the University of Amsterdam.

Chimpanzees are, along with bonobos, our closest living relatives. The largest population of chimpanzees in Tanzania, the most southern and eastern extent of this species’ range, lives in the Greater Mahale Ecosystem, which covers almost 20,000 km2. It includes the Mahale Mountains National Park, a crucial habitat for the eastern chimpanzee (Pan troglodytes schweinfurthii). ‘Despite the importance of the area – it has one of longest running research sites for chimpanzees –  there has been very little research on the chimpanzees across the entire park,’ says Chitayat. ‘There have been estimates based on small-scale or localized surveys, but no comprehensive baseline data. And without that data, it is difficult to understand chimpanzee population patterns and develop good conservation strategies. My goal was to fill that gap.’

Counting nests
Chimpanzees sleep in nests and rarely use the same nest two nights in a row, meaning they make a new one every day. By counting the nests and determining how old they were, Chitayat was able to make a reliable estimate of the chimpanzee density for sites across the entire park. She found that the density varies from 1.1 to 3.7 chimpanzees per square kilometer.

In the frontlines of climate change
The National Park is exceptionally diverse, with landscapes ranging from dense rainforests to vast savannahs. Chitayat: ‘What is striking is that the chimpanzees use the entire habitat, and not just the forested areas. We found them in both open and closed vegetation, with population density related to ecological factors such as available food sources. In open, drier areas with forests mostly in strips, there is less food and chimpanzee density is lower.

‘By looking at how the chimpanzees use the landscape and move within it, we can conclude that not only the densely forested areas are important for the protection of the animals. This ecosystem is on the frontline of climate change. That is where one of the greatest threats lies. By taking care of, for example, corridors that connect important or isolated areas, we support the ability of chimpanzees to move more freely and better protect the longevity of the population.’

Learning from sounds
Counting nests, as Chitayat has now done for the entire National Park, is a good and reliable method of monitoring chimpanzees. But it is also time-consuming and expensive. Moreover, chimpanzees are difficult to habituate (get them used to people) for up close observations. According to Chitayat, we therefore need other ways to study those that are unhabituated, which encompasses the majority of chimpanzees.

She developed a new acoustic detector based on deep learning to be used with passive acoustic monitoring. Chitayat: ‘Passive acoustic monitoring is a revolutionary technique that automatically records all the sounds in the vicinity of the acoustic device, including the sounds of chimpanzees. It can be used to find out where the chimpanzees are, how often, at what times, and how many individuals. The problem is that you have hours, days, even weeks of sound recordings that are far too laborious to listen to manually.’ Chitayat therefore investigated whether she could automate the identification of chimpanzee sounds to more efficiently sort through the vast datasets using deep learning.

From loud pant-hoots to soft grunts
To get the deep learning algorithm to work properly, it had to be fed with a lot of training data (examples of chimpanzee sounds and their environment). Chitayat: ‘That was difficult, because there are no large databases of sounds available – unlike with birds, for example. Chimpanzees make a lot of different sounds to communicate with each other, from loud pant-hoots used to impress and communicate over long distances to soft grunts used as a greeting to each other. We focused on pant-hoots, which made our task extra difficult because of the complexity and variability of these calls’.

Chitayat managed to make the acoustic detector a viable method. ‘This is a big step, but not the last. Machine learning technology could eventually be used to distinguish individual chimpanzees. That would allow you to learn more about the demography within groups – such as the number of males and females and their age class – and their patterns and habits. The more we learn, the better we can protect chimpanzees.’
