Canada, US heat wave 'on steroids' due to climate change, say experts

The western United States and Canada would likely have experienced a heat wave in the past week even without climate change. But the scale and severity of the record-breaking temperatures were undoubtedly multiplied by the changes to our atmosphere, experts say.

The US states of Washington and Oregon, as well as British Columbia in Canada, boiled this week in all-time high temperatures that have caused dozens of deaths.

"This is one of the most extreme heat waves that we have seen on Earth, in many years, anywhere, in terms of the deviation from the typical conditions in this particular part of the world," said Daniel Swain, a climate expert at UCLA, noting that temperature records are rarely broken by "more than a degree."

"In this case, those records were obliterated," he said. "It's really the magnitude and the persistence of this one that is just genuinely shocking."

Canada set an all-time record on Tuesday. In Oregon, temperatures were higher than the maximum recorded in Las Vegas, in the middle of the Nevada desert.

And all this in a region with a normally temperate climate at this time of the year.

The phenomenon causing the scorching heat is called a "heat dome." Hot air is trapped by high pressure fronts, and as it is pushed back to the ground, it heats up even more.

"It's sort of like a bicycle pump," said Philip Mote, professor of atmospheric science at Oregon State University. "If you compress air into a bike tire, it warms the air."

The condition also prevents clouds from forming, allowing for more radiation from the sun to hit the ground.

Such conditions are not unheard of: "The pattern was similar to how we always get our heat waves," Karin Bumbaco, a climatologist at the University of Washington, told AFP. "We've seen that pattern before, but it was just much stronger than usual."

- Climate like 'steroids' -


So what is causing the precedent-shattering highs?

"A world without climate change would have still had a heat wave in the Pacific Northwest. It just would have been not quite as record-setting," said Zeke Hausfather, a climate expert at the Breakthrough Institute.

"Climate is like steroids for the weather," he said "If a baseball player or Olympic athlete is taking steroids, they're still going to perform better some days and worse some days, but on average, their performance is going to go up. And so climate is doing something similar to the weather. That makes it more likely to experience these sort of extremes."

So-called "attribution studies" will be conducted to determine the exact causes of the event.

But "I think it's safe to say that there's at least some components of global climate change that contributed to this event," said Bumbaco.

Temperatures are generally higher in this region, which has warmed by around three degrees Fahrenheit in the past 100 years, so it makes sense for records to be broken little by little.

However, "it is very possible that climate change increased this heat wave to an even greater degree" than that, said Swain, the UCLA expert.

For example, the drought that has plagued the region for weeks may have bolstered the heat dome because the energy of the sun's rays is no longer being used to evaporate water, so instead it warms the atmosphere more.

And climate change is already "increasing the severity of drought" in parts of western North American, said Swain. "The answer to the question of whether it would have happened to this extent without climate change is clearly no."

- Adaptation -

It is hard to predict just how often such heat waves will occur again.

"This particular event was so extreme that it will remain unusual, even in a warming climate," said Swain. "But it has gone from the realm of being essentially impossible to being something that we may well see again."

"The bad news is that even if we could wave a magic wand and get all our emissions to zero tomorrow, the world isn't going to cool back down," said Hausfather.

"We're stuck with the warming... And so we need to be prepared for these sorts of events to be more frequent."

Experts insist on the need to adapt in the medium term: by equipping populations with air conditioners (even if they release harmful emissions in the long term), by rethinking the structure of buildings so that they reflect rather than retain heat, and by planting vegetation.

But all are unanimous: "In the longer term, obviously, the best way to prevent these things from happening in the first place, or to reduce how much worse they could get, is to reduce global emissions of greenhouse gases," said Mote.

Deforestation in the Amazon threatens one of the world's largest eagle species

June 30 (UPI) -- The harpy eagle, known in Brazil as the royal-hawk, is one of the world's largest eagle species. Like so many apex predators, the harpy eagle has suffered considerable habitat declines as a result of human development.

Though the harpy eagle's range remains extensive, its distribution and population numbers have steadily declined, and the latest research suggests deforestation in the Amazon is making matters worse.

Harpy Eagles aren't born great hunters -- they learn and develop their skills over time, and chicks and fledglings must rely on their parents for food.

According to the latest research, published Wednesday in the journal Scientific Reports, parents in heavily deforested regions of the Amazon are having a tough time finding enough food for their offspring.

"Their global distribution has contracted by 41% since the 19th century, and currently, 93% of their distribution range is within Amazonian forests, their last stronghold," researchers wrote in their paper.

For the study, scientists monitored several harpy eagle nests throughout the Amazonian forests of Mato Grosso, in Brazil.

Using direct field observations and camera footage, the researchers analyzed the hunting and feeding behaviors of harpy eagle parents.

Scientists also analyzed bone fragments near the nests to confirm what the eagles were eating.

Of the more than 300 prey items collected and documented by scientists, nearly half belonged to two-toed sloths, brown capuchin monkeys and grey woolly monkeys.

Researchers found three eaglets dead from starvation in areas featuring deforestation rates of 50 to 70 percent. In these same regions, where forest canopies are sparser, sloth and monkey numbers are depressed.

In some places, habitat losses are extensive enough to deter eagles altogether.

Roughly 35% of Mato Grosso features deforestation rates greater than 50%, and no harpy eagle nests were found in areas of the forest featuring more than 70% deforestation.

The authors of the new study determined much of the so-called "Arc of Deforestation" in the Amazon, which includes parts of Mato Grosso, is unsuitable for harpy eagles.

The latest estimates suggest deforestation in the Amazon is responsible for a loss of 3,256 breeding harpy eagle pairs since 1985.

"Our results suggest that restoring harpy eagle population viability within highly fragmented forest landscapes critically depends on decisive forest conservation action," researchers wrote in their paper.



California's blue oaks threatened by hotter temps, longer droughts

June 29 (UPI) -- The near-five-year drought that dehydrated much of California between 2012 and 2016 led to significant tree cover declines and die-offs.

According to a new study, California's famed blue oak woodlands were especially hard hit.

The latest analysis, published Tuesday in the journal Frontiers in Climate, revealed declines of more than 1,200 square kilometers, or nearly 650 square miles.

The blue oak, Quercus douglasii, which is endemic to California, can be found dotting the foothills of the Sierra Nevadas.

RELATED Climate change to blame for megadrought emerging across Western U.S.

It is the state's most drought-resistant oak species, but the new research suggests the typically resilient tree may struggle to survive more frequent and prolonged droughts.

"Our findings indicate that droughts that last several years, and which occur along with warmer than historically normal temperatures, pose serious threats to the blue oak woodlands," first study author Francis Dwomoh, researcher with ASRC Federal Data Solutions said in a press release.

"Acting in concert with wildfires, these harsher climatic conditions may lead to major tree cover loss, with negative consequences on the plants and wildlife that depend on them, as well as the goods and services we derive from this ecosystem," said Dwomoh, a researcher with ASRC Federal Data Solutions, a contractor to the United States Geological Survey Earth Resources Observation and Science Center.

California's blue oak woodlands are estimated to be the state's most widespread old-growth forest ecosystems, predating the arrival of European colonists.

The woodlands are also host to rich biodiversity, providing food and shelter for more than 300 vertebrate animal species.

Using Landsat satellite images, researchers approximated tree cover losses, as well as conditional changes, among the blue oak woodlands over the last decade. Scientists also used fire records to ensure documented losses were attributable to drought conditions.

The data showed forests that were both affected and unaffected by fire experienced significant tree cover loses and conditional changes -- partial disruption or degradation -- as a result of the mega-drought that stretched from 2012 to 2016.

The data also showed the negative impacts of wildfires in blue oak woodlands were more pronounced during the drought's hottest, driest years.

"We hope that our research findings will be useful for identifying and prioritizing the most vulnerable areas of the woodlands for appropriate management interventions," Dwomoh said.

"Furthermore, our results might be helpful to plan for more resilient blue oak woodlands and similar landscapes as the harsher climatic conditions of 2012-2016 are likely to be more common in the future," Dwomoh said.
Biden offers $50 billion to fight West wildfires, boosts firefighter pay
TO $15 PER HR!!! 
IT SHOULD BE OVER $150 PR HR



June 30 (UPI) -- President Joe Biden offered assistance Wednesday to a group of Western governors to help them prepare their states for the new wildfire season, which is well underway.

Biden offered the states $50 billion in wildfire protection and risk mitigation funds as part of a proposed bipartisan infrastructure deal.

Biden's administration also said it will help increase firefighters' pay to a minimum of $15 per hour and work with Congress to improve compensation.


"These are short-term solutions to support our federal wildland firefighters, especially due to the multiple impacts of COVID and climate change this year," the White House said in a statement.

"The administration will work with Congress on longer-term much-needed compensation, benefit, and work-life balance reforms for federal wildland firefighters."

The White House also said Biden wants to extend hiring for temporary firefighters, transition more fire personnel into the permanent positions, train and equip military personnel to respond to wildfires and increase the number of air tankers and helicopters.

Officials said Biden will also leverage satellite and other technologies to support fire crews and other emergency personnel and work with electric companies to mitigate issues with power lines and electrical grids in high-risk areas.

Wednesday's meeting, which the governors attended remotely, was attended by Vice President Kamala Harris and Govs. Kate Brown of Oregon, Gavin Newsom of California, Mark Gordon of Wyoming, Michelle Lujan Grisham of New Mexico, Spencer Cox of Utah, Steve Sisolak of Nevada, Jay Inslee of Washington and Jared Polis of Colorado.

The White House said the group and private sector partners went over the "devastating intersection of drought, heat and wildfires" in the West and developed ways to strengthen "prevention, preparedness and response efforts."

A number of fires are burning in western states -- particularly California, Arizona and Oregon. In California, for example, the Lava Fire has burned more than 13,300 acres in Siskiyou County.

"We're at a point where we're simply going to be overwhelmed year after year going forward given the current systems we have in place," Jim Whittington, an expert in wildland fire response, told the Los Angeles Times.

"We really need to look at the way we staff and work wildland fires, the way we fund them and the way we take care of our people. We need a full reset."

Some experts say the federal government's partnership will be a welcome effort after former President Donald Trump often blamed the fires on poor forest management.

Some Western governors have said Wednesday's meeting was tainted by partisan politics.

Republican Montana Gov. Greg Gianforte complained on social media that he was not invited to participate, nor were Doug Ducey of Arizona and Brad Little of Idaho.

"Disappointed to learn in news stories that [Biden] didn't offer a seat at the table to Montana and other states facing a severe wildfire season," Gianforte tweeted last week. "I hope his call for working together wasn't just lip service and Montana's invitation is just lost in the mail."

Gordon and Cox, who attended the meeting, are Republicans.
'Crazy hot': Seattle shatters all-time high-temperature record

By Mark Puleo, Accuweather.com

It's hotter than it's ever been before in the Pacific Northwest and you'll have to excuse the locals for not being totally prepared over the weekend. In a region where many households aren't equipped with air conditioning, temperatures topped 95 degrees Fahrenheit, then 100, then 105 F in what has become the most menacing heat wave in Washington history.

A week ahead of Independence Day, nature's early barbecue celebration stuck the Northwest directly into the coals.

In Seattle, residents had never experienced heat the likes of which enveloped the city Sunday. Temperatures in the Emerald City topped out at 104 degrees F, a new all-time high for a place that's more commonly thought of for its rain than its heat. Even at its coolest, the temperature never dropped below 73 F, a record-high minimum for Seattle.

In Everson, Washington, located about 100 miles north of Seattle, the heat proved so extreme that roads and sidewalks buckled. State officers shared photos of the cracked roadways, which rendered the streets unsafe and caused detours.

In Yakima, located in the southeastern portion of the state, other Twitter users shared photos of sidewalks buckling under the heat and popping out of the ground.

Dr. Kristie Ebi, a professor at the University of Washington, told AccuWeather National Reporter Bill Wadell that she was particularly concerned for high-risk residents of the area, such as the elderly.

"We're well under 50 of people who have access to air conditioning," she said. "I was quite surprised a couple of years ago when we had a heat wave...I was the only one who had air conditioning, no one else did."

Before Sunday's rotisserie, Seattle's prior record high of 103 F was set on July 29, 2009, the same day on which high-temperature records were also set in Olympia and Shelton. Both of those cities also had all-time records fall on Sunday, too, with Olympia reaching 105 and Shelton maxing out at 107, according to the National Weather Service.

The brutal heat ushered residents indoors and shuttered businesses as officials urged people to stay out of the sun's wrath.

Kevin Darras, of IAMDARRAS, sells custom-made T-shirts at Seattle's famed Pike Place Market and on Sunday told Wadell that the weather made a direct impact on his sales.

"The crowds are here, but they're dissipating early. So we have to get here, get set up, get comfortable and try to make some sales," Darras said. "It's definitely affecting sales -- probably cut in half. Still lucky to be down here and enjoying the weather. Even if it's hot, we're staying cool."

At its peak broil, the mercury in thermometers even touched the 115 mark in Pasco, Washington, on Sunday. On Monday, Portland, Oregon, saw temperatures reach 115 as well -- the third consecutive day the city has set a new all-time record high.

That kind of heat is enough to make any visiting tourists question their vacationing decisions. Eden Marcus, visiting Seattle from Chicago, told Wadell that increased amounts of water and sunscreen have aided in saving the trip.


"It's crazy hot. Right now it's breezy but when you're standing still it's insane to be outside for more than a few minutes," he said.

But unlike many others in the city, Marcus' stay includes air conditioning. For residents, such as Sheri Grittman, the heat has been severe enough to consider moving to another state.

Grittman, her husband and their two cats became full-time RVers four years ago, she told Wadell, and the mobile homes one air-conditioning unit is certainly not doing the trick.

"Portland gets triple digits, where I'm from, but not up here, it's always about 10 degrees cooler always from Portland. Very abnormal," she said.

The heat proved daunting enough for Grittman that she even told Wadell on Sunday that she was looking forward to returning to work after the weekend for the sake of air conditioning.

"I'm gonna love work," she exclaimed. "It's Monday and I'm gonna love work!"

The heat wave's wrath began in earnest last week in Washington before spiking over the weekend. Farther north, high-temperature recordings of 116 F in British Columbia broke the all-time record for the highest temperature ever recorded in Canada.

In Oregon, it was in Eugene where the heat may have the most notable impact, forcing a temporary halt to the U.S. Olympic Track and Field Trials on Sunday. Athletes were forced to wait for the brunt of heat to calm down before competition could restart.

Hundreds of deaths linked to historic heat wave in western Canada



June 30 (UPI) -- More than 230 people in the Western Canadian province of British Colombia died last weekend amid an historic heat wave, authorities said.

Lisa Lapointe, the chief coroner for the province, said in a statement Tuesday that at least 233 people have died from the heat between Friday and Monday.


"Since the onset of the heat wave late last week, the B.C. Coroners Service has experienced a significant increase in deaths reported where it is suspected that extreme heat has been contributory," Lapointe said.

Lapointe said the office usually receives about 130 deaths over a four-day period, and added that she expects the death toll to rise.

"Environmental heat exposure can lead to severe or fatal results, particularly in older people, infants and young children and those with chronic illnesses," she said.

Police in Vancouver called on residents to check on loved ones because resources are depleted due to the rise in heat-related deaths.

"Vancouver has never experienced heat like this, and sadly dozens of people are dying because of it," said Vancouver Police Department Sgt. Steve Addison in a statement. "Our officers are stretched thin, but we're still doing everything we can to keep people safe."

RELATED 'Crazy hot': Seattle shatters all-time high-temperature record

E-Comm 9-1-1, the province's largest emergency communications center, said it responded to nearly 8,000 calls Saturday and more than 7,300 on Sunday -- record breaking numbers.

"This is a historic increase of approx. 55% compared to a normal weekend in June," it said in a statement.

The deaths occurred as the province and the Pacific Northwest experiences a record-breaking heat wave.

The province's official weather and climate source, Environment and Climate Change Canada Weather British Columbia, has reported three straight days or record breaking temperatures.

"Words cannot describe this historic event," it said on Twitter.

On Monday, 59 temperature records were broken in the province, 43 of which set all-time records, it said Tuesday.

The service added that Lytton has broken the all-time Canadian heat record three days in a row and the 121.1 degrees Fahrenheit it reached Tuesday is hotter than Las Vegas' all-time record high of 117 degrees Fahrenheit.

"We've never seen anything like this, and it breaks our hearts," Addison said. "If you have an elderly or vulnerable family member, please give them a call or stop by to check on them."

In Burnaby, authorities responded to more than 25 deaths where heat is believed to have been a contributing factor in the past 24 hours, the Royal Canada Mounted Police said in a statement.

In Surrey, which borders Burnaby to the south, the RCMP said it was deploying more officers "following an unprecedented number of sudden deaths over the past two days."

"Please check in on your loved ones, your neighbors, friends who may be vulnerable during this heat," the Surrey RCMP said in a tweet.


Village of Lytton, B.C., evacuated as mayor says 'the whole town is on fire'

© MLAZZ Creative by Matt Lazzarotto A plume of smoke from the Sparks Lake wildfire, burning northwest of Kamloops, B.C., covered an estimated 40 square kilometres as of Wednesday morning.

The mayor of Lytton, B.C., said he has ordered the entire town to be evacuated after a fast-moving wildfire swept in on Wednesday evening.

Mayor Jan Polderman said he told everyone in town to leave as the situation rapidly deteriorated.

"It's dire. The whole town is on fire," Polderman told CBC News. "It took like a whole 15 minutes from the first sign of smoke to all of a sudden there being fire everywhere."

Fire information officers with the B.C. Wildfire Service said they were unable to provide an update on the situation in the Fraser Canyon village.

This week, Lytton recorded the highest temperature ever seen in Canada on three consecutive days, topping out at 49.6 C on Tuesday.

This is a developing story. The previous version of the story is below.

Wildfire crews spent Wednesday dealing with aggressive fires across B.C.'s Interior in the aftermath of a record-breaking heat wave.

A growing number of people were being forced out of their homes and a number of highways were closed as existing fires spread and new ones were sparked in the hot and dry conditions.

The Sparks Lake wildfire, 15 kilometres northwest of Kamloops Lake, is now an estimated 40 square kilometres in size and has forced the evacuation of more than 160 homes in the area.

The B.C. Wildfire Service says 56 firefighters are on site fighting the blaze, as well as 10 helicopters and 2 pieces of heavy equipment. Fire information officer Madison Smith said helicopters struggled with the heat on Tuesday, and some were grounded as their engines overheated.

Not far away, the Mckay Creek fire burning 23 kilometres north of Lillooet has grown to 50 square kilometres in size and is classified as out of control. There are 24 firefighters on scene, along with four helicopters and five pieces of heavy equipment.

Late Wednesday, two new fires were reported north of Big White in the Okanagan, and firefighters were reporting aggressive fire growth and heavy smoke that could be seen from Kelowna, Vernon and other nearby communities.

Together, they are estimated to measure about three square kilometres.

Another fire was sparked Tuesday near Lytton, where the all-time highest recorded temperature in Canada has been registered three days in a row, and where crews have been fighting the George Road fire since last Wednesday.

Bernie Fandrich, who lives on George Road in Lytton, said the fire started within a kilometre of his home.

"There was a very, very competent crew," he told the CBC's The Early Edition. "They did a remarkable job in bringing it under control and protecting the residences around here."

Now, he said the fire has moved up the mountain to the east of his home, and the air in Lytton has been smoky for the past two days.

That blaze, the Conte Creek fire, is estimated to be about 1.5 hectares in size.

Erica Berg, a provincial fire information officer, said in northeastern B.C., nine wildfires had been reported since lightning storms swept through the region Monday and Tuesday. Berg said there have been 26 new fires in the last two days as the risk across most of the province is rated at high to extreme.
Evacuation orders, alerts

Evacuation orders were issued for several properties in Electoral Area B in the Squamish-Lillooet Regional District, as the Mckay Creek wildfire threatened homes on Tuesday.

On Wednesday evening, 136 properties in the Thompson-Nicola Regional District were ordered to evacuate because of the Sparks Lake wildfire. That's in addition to another 27 properties that were placed under evacuation order on Tuesday and Wednesday morning.

Nine properties in the Thompson-Nicola Regional District were evacuated Tuesday out of concern that the Sparks Lake wildfire would threaten homes and other structures. Another 18 properties were put on evacuation order Wednesday morning.

The Sparks Lake wildfire has also prompted evacuation alerts for a total of 421 properties in the Deadman, Red Lake, Tranquille Valley, Vidette Lake, Loon Lake and Hihium Lake areas.

Marshall Potts and Jo-Anne Beharrell, who live about 1.5 kilometres from the fire, were ordered to leave the area Tuesday afternoon.

They packed up their vehicle on Monday night, knowing they'd likely have to leave at the drop of a hat.

The pair are staying with family in Pinantan Lake, about 75 kilometres away, with their two dogs.

"It was very stressful," Beharrell said. "The not knowing and wanting to get back and check on everything is really overwhelming."

They had to leave their cattle behind, but left the gates open so they could get away if the fire comes too close. They also had to leave their chickens and two cats, which they couldn't find.

They hadn't heard anything about the status of their property by Wednesday morning.

Potts, a musician, says the area is a great place to be creative.

"We live in a beautiful part of the world up there," he said. "It's devastating to actually see so much devastation to that natural beauty."
Multiple highway closures

Wednesday evening, DriveBC reported that two wildfires had closed highways to the north and south of Lytton. As of 6 p.m. PT, Highway 1 was closed between Boston Bar and Spences Bridge, while Highway 12 is closed from Lillooet to the junction with Highway 1.

Meanwhile, Highway 97 north is closed for 59 kilometres between Sikanni Chief Road and Prophet River Sub Road, in order to protect the public from two wildfires near the Pink Mountain area in northern B.C.

"The highway will remain closed there until there's no public safety concern," B.C. Wildfire Service information officer Sharon Nickel said. "We will have personnel on site to continue assessing the situation."

That fire is currently listed at 48 square kilometres in size and was sparked by lightning.

Nickel said everywhere in the Prince George fire centre is extremely dry right now, and she expects those conditions to continue.

In the Cariboo, a fire sparked Wednesday about 35 kilometres east of Horsefly has led to the closure of the McKinley Lake recreation campsite. Thirty-two-firefighters are responding along with a helicopter.

The wildfire service says the fire is highly visible from the surrounding communities but no structures are currently at risk.
Possibility of lightning in forecast

While the air has cooled off in Vancouver, high temperatures look set to continue in the Interior this week as the "heat dome" moves east, with Kamloops and Kelowna forecast to hit temperatures in the high 30s and the low 40s in the coming days.

Vancouver Island and northern B.C., where fire danger is extreme, have seen lightning strikes this morning, according to CBC meteorologist Johanna Wagstaffe.

Those strikes will migrate east today, and new fire startups are likely.

Environment Canada is predicting a chance of thunderstorms throughout the Interior on Wednesday afternoon and evening.
Backcountry still open amid wildfire risk

John Hawkings, the director of recreation sites and trails with B.C.'s Ministry of Forests, says despite the wildfire risk, the backcountry won't be closed for the Canada Day long weekend.

"Closing the forest is not as simple as putting up a fence," Hawkings said Wednesday to Chris Walker, the host of CBC's Daybreak South.

"We have thousands of recreation sites and bike parks and places that people get out to enjoy, and it's a healthy activity," he continued. "Closing the backcountry is an extreme measure."
Greta Thunberg Warns The Heat Wave Is 'Just Getting Started' As Canada Breaks Temp Records

Swedish climate activist Greta Thunberg has made her opinion on Canada's record-breaking high temperatures pretty clear!

In a tweet on June 28 — one day after Canada broke its own all-time heat record — the 18-year-old warned that "This heat-wave is just getting started."


"Highest temperature ever recorded in the planet north of 50N latitude also shattered (44.4C from July 1941)," Thunberg wrote, responding to the news that Canada recorded sweltering temperatures of 46.6 C.

She went on to say that heat records are usually broken by decimal points "like a tenth of a degree," and particularly not in months like June.

"This heat-wave is just getting started," the activist said, before adding the hashtag "#FaceTheClimateEmergency."

On June 27, in the middle of a "heat dome" across western Canada, a village in B.C. reached a sizzling 46.6 C (116 F).

Sunrise Movement calls for key climate inclusions in Biden infrastructure plan

June 28 (UPI) -- Members of the Sunrise Movement protested outside of the White House on Monday calling for President Joe Biden to prioritize the fight against climate change in his infrastructure bill.

Protesters from the climate change action group chanted "no climate, no deal" and "Biden, you coward, fight for us" as Reps. Alexandria Ocasio-Cortez, D-N.Y., and Jamaal Bowman, D-N.Y., joined the crowd.


The protest comes after Biden last week announced a $1.2 trillion infrastructure agreement with a group of bipartisan lawmakers that includes $579 billion in new spending but did not include an increase on gas tax or fees on electric vehicles and wouldn't require an increase on taxes from people earning less than $400,000.


One of the provisions protesters demanded was the creation of a Civilian Climate Corps, a federal entity to focus on job creation in renewable energy and other green industries.

Sunrise Movement organizer Nikayla Jefferson said Biden should negotiate with those who helped to elect him.

"We elected you -- the youth vote carried the election. If you are going to negotiate on our lives and livability of our planet, negotiate with us," Jefferson said. "So we will sit here until you commit to the side of climate justice, commit to an American Jobs Plan written with bold ambition against the climate crisis including a Civilian Climate Corps, and pass it through with reconciliation immediately -- or you will not pass a bill at all."

Ocasio-Cortez pledged that lawmakers would fight to get such a provision into the infrastructure bill.

"They want you to think, 'Oh, this is a new idea, this is too ambitious, this is too crazy.' How about this? The last time we introduced the Civilian Climate Corps in this country, we hired and mobilized a quarter-million people in three months," she said.

White House press secretary Jen Psaki on Monday said she disagreed with the notion that the bipartisan agreement "doesn't do anything for climate," stating it includes investments addressing legacy pollution, clean energy transmission and electric vehicle buses.

"Whether or not everyone is aware of all those specifics, that's incumbent on us to keep conveying that, communicating it, listening and making sure people understand that this is a down payment and the president will continue to advocate for, press for, work for,even more on climate as he will in the reconciliation bill in the process moving forward," she said.

Trees may be key to cooler temps during the summer, study says
By HealthDay News

Could trees be the key to a cool summer in the city?

Yes, claims new research that calculated just how much greenery can bring temperatures down.


"We've long known that the shade of trees and buildings can provide cooling," said study co-author Jean-Michel Guldmann. He is a professor emeritus of city and regional planning at Ohio State University, in Columbus.

"But now we can more precisely measure exactly what that effect will be in specific instances, which can help us make better design choices and greening strategies to mitigate the urban heat island effect," Guldmann said in a university news release.

RELATED Commercial forests could produce long-term climate benefit



For the study, his team created a 3D digital model of a nearly 14-square-mile area of northern Columbus to assess the effect that shade from trees and buildings had on land surface temperatures over one hour on a summer day.

The researchers found that the amount of tree canopy had a significant impact on what's known as the urban heat island effect.

For example, on a day when the temperature was 93.33 degrees Fahrenheit in one neighborhood, the temperature would have been 3.48 degrees lower -- 89.85 degrees -- if all the current trees had been fully grown.



RELATED New urban planning software may inspire more sustainable cities


And if the neighborhood had 20 more full-grown trees, the temperature would be another 1.39 degrees lower.


The researchers also found that both shaded and sun-exposed grassy areas had significant heat-reducing effects, but shaded grass provided more cooling than sun-exposed grass.

As expected, buildings increased the temperature, but shadows cast by them could significantly cool temperatures, particularly if they shaded the rooftops of adjacent buildings, the study authors said.

RELATED Most low-income blocks in U.S. cities are hotter, have fewer trees


For example, a 1% increase in the area of a building led to average surface temperature increases of between 2.6% and 3%. But an increase of 1% in the area of a shaded rooftop led to average temperature decreases of between 0.13% and 0.31%, the researchers found.


Shade on roadways and parking lots also significantly decreased temperatures, according to the study published online recently in the journal Computers, Environment and Urban Systems.

"We learned that greater heat-mitigation effects can be obtained by maximizing the shade on building rooftops and roadways," Guldmann explained.

The type of information provided by the model can be used to "formulate guidelines for community greening and tree planting efforts, and even where to locate buildings to maximize shading on other buildings and roadways," Guldmann said. "This could have significant effects on temperatures at the street and neighborhood level."More information

When child care centers were forced to close in the pandemic's early months, hundreds of thousands of American working mothers lost their jobs, new research shows.

The study is just the latest illustration of the toll the pandemic has taken on working women in the United States.

Over the first 10 months of the U.S. pandemic, more than 2.3 million women left the labor force, according to the National Women's Law Center. That compared with just under 1.8 million men.

That was, in part, because many job losses were in industries where women make up much of the workforce. On top of that, working mothers -- more than fathers -- faced the difficulty of having kids home from school or day care.

The new study looked specifically at the impact of pandemic child care closures.

It found that in states that had closures in spring 2020, women's job losses were particularly acute. In contrast, the employment decline among men was similar to that of men in other states.

Nationwide, the gap amounted to about 611,000 lost jobs among working mothers

"The effect was concentrated among women with young children," said lead researcher Yevgeniy Feyman of the Boston University School of Public Health.

That, he said, suggests that child care closures, themselves, fueled many of the excess job losses.


That is likely the case, agreed Rasheed Malik, who studies child care policy at the Center for American Progress, a nonpartisan policy institute in Washington, D.C.

"Prior to the pandemic," he said, "there was already a strong relationship between local availability of child care and women's participation in the workforce."

The pandemic only worsened the longstanding problem of child care "deserts," Malik said. Those are areas across the country -- typically low-income -- where working parents lack affordable, quality child care options.


Child care centers did reopen in closure states by June 2020, according to Feyman's team. But while many women and men did go back to work, women still lagged behind as of December 2020, the study found.

They were less likely than men to be employed, and their employment rate remained below its pre-pandemic level.


Simply allowing child care centers to reopen didn't necessarily solve families' problems.

For one, Malik said, an estimated 10% of programs closed for good. And at those that did survive, staff reductions meant fewer families could be served.

"Getting back into the system wasn't just a matter of going back to the program you'd been in," Malik said.

The findings are based on data from a monthly labor force survey. It included nearly 49,000 U.S. adults, including more than 13,000 from states where child care centers shut down by April 2020.


Employment among men and women in all states dropped sharply in April 2020, but women in states with child care closures saw the steepest drop-off. The likelihood of women being employed during the closure period was 2.6 percentage points lower, compared to men.

That translated to 611,000 job losses among 23.5 million working mothers, the researchers estimated.

To Feyman, one implication is that American workers need better paid family leave, and a "cultural shift" where not only women, but men, take it.

Malik pointed to some fundamental issues that make finding reliable child care so difficult, pandemic or not.

Unlike public education, he said, the child care system is "market-based" -- with programs concentrated in more affluent areas where families can afford the cost.

"We think of it as a market failure," Malik said. "We don't have public school deserts, but we do have them in child care."

To make quality care accessible to more families there must be some level of government subsidy as well as assistance to low-income families, he said.


That "investment in families" would be repaid in parents' increased productivity and the educational and social benefits young children gain from being in high-quality programs, Malik said.

Another problem is the field's generally low pay and high turnover.

"These are difficult jobs," he added. "The work is rewarding, but definitely not financially rewarding."

Malik said that low pay is rooted in "historical bias" that undervalues the work of women, who make up the vast majority of the child care workforce.

"It's about time we honor the decades of hard work they've given us," Malik said.

The findings were published online recently in JAMA Health Forum.More information
