Is climate change to blame for the recent weather disasters? 2 things you need to understand

Summer isn’t even half over, and we’ve seen heat waves in the Pacific Northwest and Canada with temperatures that would make news in Death Valley, enormous fires that have sent smoke across North America, and lethal floods of biblical proportions in Germany and China. Scientists have warned for over 50 years about increases in extreme events arising from subtle changes in average climate, but many people have been shocked by the ferocity of recent weather disasters.

A couple of things are important to understand about climate change’s role in extreme weather like this.

First, humans have pumped so much carbon dioxide and other planet-warming greenhouse gases into the atmosphere that what’s “normal” has shifted. Extreme heat waves that were once ridiculously improbable are on their way to becoming more commonplace, and unimaginable events are becoming possible.

Second, not every extreme weather event is connected to global warming.







Shifting the bell curve

Like so many things, temperature statistics follow a bell curve – mathematicians call these “normal distributions.” The most frequent and likely temperatures are near the average, and values farther from the average quickly become much less likely.

All else being equal, a little bit of warming shifts the bell to the right – toward higher temperatures. Even a shift of just a few degrees makes the really unlikely temperatures in the extreme “tail” of the bell happen dramatically more often.
NASA mapped the changing temperature bell curve year by year starting in 1951.

The stream of broken temperature records in the North American West lately is a great example. Portland hit 116 degrees – 9 degrees above its record before the heat wave. That would be a once-unimaginable extreme at the end of the tail, but it’s now inching closer.

The width of a bell curve is measured by its standard deviation. About two-thirds of all values fall within one standard deviation of the average. Based on historical temperature records, the heat wave in 2003 that killed more than 70,000 people in Europe was five standard deviations above the mean, so it was a 1 in 1 million event.

Without eliminating emissions from fossil fuels, heat like that is likely to happen a few times a decade by the time today’s toddlers are retirees.

So, is climate change to blame?

There’s a basic hierarchy of the extreme events that scientific research so far has shown are most affected by human-caused climate change.

At the top of the list are extreme events like heat waves that are certain to be influenced by global warming. In these, three lines of evidence converge: observations, physics and computer model simulations that predict and explain the changes. At the bottom of the list are things that might plausibly be caused by rising levels of greenhouse gases but for which the evidence is not yet convincing. Here’s a partial list.

1) Heat waves: Studies show these are certain to increase dramatically with global warming, and indeed that’s exactly what we’re observing.

2) Coastal flooding: Heat is causing ocean waters to expand, pushing up sea levels and melting ice sheets around the world. Both high-tide flooding and catastrophic storm surge will become much more frequent as those events start from a higher average level because of sea level rise.

3) Drought: Warmer air evaporates more water from reservoirs, crops and forests, so drought will increase because of increased water demand, even though changes in rainfall vary and hard to predict.

4) Wildfires: As the western U.S. and Canada are seeing, heat dries out the soils and vegetation, providing drier fuel that’s ready to burn. Forests lose more water during hotter summers, and fire seasons are getting longer.

5) Reduced spring snowpack: Snow starts accumulating later in the fall, more water is lost from the snowpack during winter, and the snow melts earlier in the spring, reducing the flush of water into reservoirs that supports the economies of semiarid regions.

6) Very heavy rainfall: Warmer water can transport more water vapor. Damaging rainstorms are due to strong updrafts that cool the air and condense the vapor as rainfall. The more water is in the air during a strong updraft, the more rain can fall.

7) Hurricanes and tropical storms: These derive their energy from evaporation from the warm sea surface. As oceans warm, larger regions can spawn these storms and provide more energy. But changes in winds aloft are expected to reduce hurricane intensification, so it’s not clear that global warming will increase damage from tropical storms.

    Here, changes in coastal sea surface temperature are estimated, showing that although 71% of the world's coastlines are warming, the rates of change have varied spatially.



8) Extreme cold weather: Some research has attributed cold weather than moves south with the meandering of the jet stream – sometimes referred to as “polar vortex” outbreaks – to warming in the Arctic. Other studies strongly dispute that Arctic warming is likely to affect winter weather farther south, and this idea remains controversial.

9) Severe thunderstorms, hail and tornadoes: These storms are triggered by strong surface heating, so it’s plausible that they could increase in a warming world. But their development depends on the circumstances of each storm. There is not yet evidence that the frequency of tornadoes is increasing.
A warning that can’t be ignored

The catastrophic impacts of extreme weather depend at least as much on people as on climate.

The evidence is clear that the more coal, oil and gas are burned, the more the world will warm, and the more likely it will be for any given location to experience heat waves that are far outside anything they’ve experienced.

Disaster preparedness can quickly fail when extreme events blow past all previous experience. Portland’s melting streetcar power cables are a good example. How communities develop infrastructure, social and economic systems, planning and preparedness can make them more resilient – or more vulnerable – to extreme events.

Understanding the Fossil Fuel Industry’s Legacy of White Supremacy

In December, The New York Times published a story revealing how ExxonMobil and other oil companies had paid a public relations firm named FTI to build “news” and information websites falsely suggesting grassroots support for the fossil fuel industry and its initiatives. ExxonMobil, which didn’t speak with Times reporter (and my former coworker) Hiroko Tabuchi for the story, responded by trying to smear the messenger. “We refused to work with the author,” ExxonMobil tweeted, “because of her obvious bias against the oil and gas industry.”

The firm was alluding to an October tweet by Tabuchi that she’d “been thinking a lot about fossil fuels and white supremacy recently,” noting that nearly every oil industry official she’d encountered as a reporter was white and male. ExxonMobil complained the tweet was a “baseless claim alleging industry links to white supremacy,” and Tabuchi later deleted it. But according to University of Notre Dame historian Darren Douchuk, Tabuchi’s tweet reflected something real.

“In researching the history of oil in modern America since the 1860s to the present, oil was I think unquestionably the most racially homogenous industry in America. And, there are clear racist patterns of organization within the industry from the very beginning,” says Douchuk, author of Anointed with Oil: How Christianity and Crude Made Modern America.

White supremacy can be narrowly defined as a system of overtly racist individuals who seek to oppress or eliminate anyone who is not white, and more broadly as a system designed to protect and elevate whiteness. This latter definition shifts the focus from a few explicitly racist individuals to the underlying system of norms that give white people a disproportionate advantage. A banal example is when a nightclub establishes a “No Timbs” policy, referring to the brand of work boots long fashionable in Black hip-hop culture, to exclude young Black male patrons.

These norms can also oppress Black people and elevate white people in more enduring ways. People with “Black” names get fewer calls for job interviews compared to similarly qualified white people. Homes with a Black owner are typically appraised at lower values than those whose owners are perceived to be white.

Whichever definition you choose, says Douchuk, the historical record reveals clear links between white supremacy and the oil industry. According to his research, when crude oil was discovered in the hills of northwestern Pennsylvania just prior to the Civil War, it was seen “as a mystical fount that might ease America out of bloodshed and into a new age of peace and prosperity. Oil was to be a healing balm for the body politic.”

But this healing balm was intended for “whites only,” and that wasn’t just because in that era few Black people lived in the communities where oil was first extracted. As the industry shifted west and south at the turn of the 20th century, to Texas, California, and Mexico, it collided with the emergence of the “Lost Cause” mythos across the South, a set of pseudo-historical justifications for slavery as a just system in which the enslaved were happy, and the Civil War was a heroic insurrection to protect the South’s “economic prosperity” from “Northern aggression.” The Lost Cause lie erases from history the reasons that abolitionists like Harriet Tubman, Denmark Vessey, and Nat Turner fought for Black liberation.

White oilmen (they were almost all men) saw oil as a resource that could help the South rebuild, while also re-installing a system that ensured Black people would remain structurally at the bottom of their racial hierarchy. So they codified segregation into the oil fields. “The oil industry circa 1901 [and] going forward is very much implanted in regions of Texas and Oklahoma that are typically places where lower-class whites have been fighting and clawing for privilege on the racial ladder,” says Douchuk, “fighting against, as they see it, rising Black southerners who want also a place on the economic pecking order.”

One way the industry accomplished this in the South was by limiting the types of work available to people of color. By the early 20th century, white oilmen had firmly established a pattern of keeping the most lucrative roles in the oil business for themselves, says Douchuk, while relegating the most difficult and least profitable to Black and Mexican American workers, such as drilling pipe and laying pipelines that could weigh upwards of 600 pounds through mosquito-infested swamps.

The oil industry also segregated its employees in other ways. Black workers typically lived in tents, compared to sturdier lodging for white workers. Black workers were left to feed themselves, often turning to hunting, despite earning a fraction of the pay of white workers who were fed on the company dime.

Oil towns were also scenes of brutal attacks by whites against Blacks, according to Douchuk. “Traditionally, this is where a lot of the most violent lynching has gone on,” he says. Texas was so violent that Black oil workers who managed to eke out enough money sometimes sought safer pastures in Oklahoma. But that was no guarantee of safety. The story of the 1921 Tulsa Riots, in which white rioters killed 36 Black people in Tulsa, Oklahoma and obliterated the city’s prosperous Greenwood district (known as “Black Wall Street”), gained new public attention in 2019 when it was featured in the opening episode of HBO’s “Watchmen.” But the fact that Tulsa was an oil town, then nicknamed the “Oil Capital of the World,” is less remarked upon.

This kind of racist violence was common among oil towns. The Tulsa massacre was just unique in the scale of the destruction.

ExxonMobil has roots in this era, going all the way back to the 1911 founding of the Humble Oil & Refining Company in Humble, Texas. Humble Oil was soon acquired by Standard Oil of New Jersey, which in 1972 became the Exxon Corporation, which merged with Mobil (formerly the Standard Oil Company of New York) in 1999

Even as the oil business went all in on Jim Crow, Black workers began to carve out spaces for themselves in the lumber and shipping industries. By 1910, Black laborers made up 59.1 percent of the timber workforce in Louisiana, and 38 percent in Texas. But as late as 1940, Black oil workers only accounted for 0.05 percent of all employees in oil production, and 3 percent of refinery workers.

American oilmen also exported this bigotry. During early-20th-century oil exploration in Mexico, U.S. firms relegated Black and Chicano workers to “the hot, dirty, and unskilled jobs: clearing land, doing laundry, cooking and washing, cleaning buildings, and carrying equipment,” according to Jonathan Brown’s book Oil and Revolution in Mexico. In the 1930s, Texaco chief executive Torkild Rieber was a Nazi sympathizer whose company would go on to literally fuel Hitler’s regime. In Saudi Arabia, Standard Oil Company of California (now part of BP) created “a system of privilege and inequality, which we know as Jim Crow in the United States, as Apartheid in South Africa, and as racism more generally,” writes University of Pennsylvania political scientist Robert Vitalis in America’s Kingdom: Mythmaking on the Saudi Oil Frontier, and brought the system with it to Latin America and Indonesia as well. In Libya, Esso (another ExxonMobil precursor) created a “settler community” based on architectural separation between Libyans and white American, British, and Canadian employees.

The U.S. Civil Rights Movement of the 1950s and 1960s, along with the decolonization movements across Asia and Africa, sought to upend some of these racist hierarchies. But the oil industry’s white supremacy remained entrenched. As reported recently in Drilled News, in 1994 financial analyst Bari-Ellen Roberts and five colleagues filed a class action suit against Texaco (now Chevron) after she was passed over for a promotion, and then asked to train the white man who got the job. In 1996, Richard A. Lundwall, a dismissed Texaco executive, turned over recordings of senior Texaco officials discussing the lawsuit to the plaintiffs’ lawyers in which they considered destroying incriminating evidence related to the suit. They referred to Black employees as the “N-word” and “Black jelly beans,” helping make Roberts’ case.

After winning a $176 million settlement — the largest to date in a corporate discrimination lawsuit — Roberts wrote a book chronicling the racism she had encountered at Texaco. In one incident, a white employee poked his head into Roberts’ office and exclaimed, “Well, Jesus Christ, I never thought I’d live to see the day when a Black woman had an office at Texaco.” In another, Roberts discovered her performance grade was lowered because a manager considered her “uppity,” a racist dog whistle suggesting that a Black person was moving beyond their “station.” Roberts also learned that behind her back, one of her bosses had referred to her as a “little colored girl.”

This kind of bigotry isn’t relegated to the last century. Just four years ago, NPR reported on discrimination in oil fields. One former Black employee who spoke to reporter Jeff Brady described finding phrases like “n***** go home” scribbled onto a pipe, and nooses being left for him and other Black workers to find. Late last year, a class action lawsuit was filed against Pipeliners Local Union 798, a major pipeline workers trade union of more than 8,000 members, alleging that the union refused to employ Black workers (and white women) through the 1980s. The suit contends that even today Black workers are consistently hired for less well-regarded and more poorly paid “helper” roles, but passed over in favor of less qualified white employees for the better-paid “journeyman” roles. Everything old, it seems, is indeed new again.

The links between the oil industry and white supremacy extend beyond the corporate office and the drill pad. Refineries and other industrial sites are deliberately and disproportionately sited in or near communities of color. Race can predict which communities will and won’t get cleaned up after an oil spill. One could argue that white supremacy within the oil industry is so much the norm, that it is easier to point to the exceptions.

When firms like ExxonMobil make accusations of bias against those who, like The Times’ Hiroko Tabuchi, point out the historic links between the oil industry and white supremacy, they are trying to rewrite more than a century of well-documented racism into a rosier history. “They’re coming out of certain assumptions of racial privilege, which they might not even be able to articulate,” says Douchak. But learning from previous generations frees us to make new advances and avoid catastrophic pitfalls.

As James Baldwin, the acclaimed activist and writer, once wrote, “we are trapped in history.” The present is built upon the past, and will be constrained by it until we face up to these devastating truths. Will the oil industry embrace that reckoning? “I think there’s been an effort lately to improve on that,” Douchak says, “but that, that is a legacy. And it’s not just a legacy, but it’s something that needs to be confronted.”

Boris Johnson ‘Missing in Action’ Ahead of COP26 Climate Summit, Say Campaigners

Protesters in Parliament Square this morning said the government was failing to show enough leadership in the run-up to the UN summit, due to start in Glasgow in 100 days.

Climate campaigners have called on the UK government to step up its action ahead of the COP26 UN summit set to take place in Glasgow in November, which they say is in “serious jeopardy”.

A hundred protesters gathered in Parliament Square this morning to mark 100 days before the talks begin, accusing Prime Minister Boris Johnson and Chancellor of the Exchequer Rishi Sunak of being “Missing in Action”. They held banners with the phrase “The climate needs you” and giant alarm clocks to emphasise the urgency of tackling climate change.

The action was organised by The Climate Coalition, a group of civil society organisations pushing for greater action on climate change.

Ben Margolis, Interim Director, said: “Time is quickly running down until the UN climate talks arrive in Glasgow in November for the biggest diplomatic event the UK has seen in decades – essential to limiting warming of the Earth to 1.5C or less.

“The Prime Minister has pledged that the UK will show global leadership on climate change. Yet despite this, Boris Johnson and Rishi Sunak are most noticeable for being missing in action and failing to deliver real, concrete progress to tackle the nature and climate emergencies.”

Climate groups are increasingly concerned about a lack of action from the government ahead of the summit, the largest of its kind since the historic Paris Agreement was signed in 2015.

The protest comes two weeks before the Intergovernmental Panel on Climate Change is due to publish its Sixth Assessment Report, which will highlight that the window to keep the 1.5C target alive is closing. It will warn of a rise in heatwaves, destruction of 90 percent of global reefs, accelerated sea level rise and stronger hurricanes and typhoons.

Last week, 100 of the world’s poorer countries issued a position paper setting out five key issues which they say are essential for them in the negotiations, including a the delivery of a 2009 promise from richer countries to provide $100bn a year in climate finance support by 2020. They point to a lack of progress seen so far, particularly at the G7 meeting in the UK last month.
‘Far-Off Promises’

Sarah Wiggins, who was present at the protest from Christian charity Tearfund, told DeSmog: “We’ve seen these heat waves in Canada, and the US, but also in places like Pakistan, where people were literally dropping dead from 50-degree heat. And in other countries, they don’t have the facilities. We have to respond to these disasters.

“So there’s a real injustice. We want to see the richer countries like the UK coughing up money on the table and acting with real urgency, because this is about the total emergency.”

Daniel Hale, another campaigner, said: “The action that we take this year is going to be so much easier than the action that we take in 20 years’ time.

“It’s never been more important that we act on climate change. It’s always easier to make promises than to deliver and the way the system works everyone is incentivised to make huge far-off promises in the future.”

G20 representatives have gathered today in Italy for an Energy and Climate ministerial meeting, which will focus on how to ensure sustainable growth and a clean energy transition.

Greenpeace UK’s Executive Director, John Sauven, said: “These pivotal climate talks require bold policies, tough targets and political will from all governments. But, as hosts, it’s up to the UK to drive this forward by setting a prime example for others to follow.

“However, the consistent failure of the UK government to match its rhetoric with required action has put the most important international meeting the world has ever seen in serious jeopardy. Boris Johnson has just 100 days to get his own house in order.”

He said this meant scrapping high-carbon plans, such as the proposed new “Cambo” oilfield in the North Sea and cuts to the aid budget.

A government spokesperson said: “Over the past three decades, the UK has seen the fastest fall in emissions of any G7 country, made tangible progress in boosting renewable energy and green growth, and set some of the world’s most ambitious emissions reduction targets.

“Against this backdrop, the Prime Minister continues to call for greater global ambition and action to tackle climate change ahead of COP26, as he has done through numerous international summits and his engagement with individual world leaders.”
WATCH: Biden leaves conservative reporter speechless after bringing up the GOP's QAnon problem

A blunt-talking President Joe Biden shut down a conservative reporter on Thursday night who asked if Democrats are defunding police departments -- firing back with a question about a QAnon claim that left the reporter grasping for an answer.

As Biden walked across the South Lawn, he engaged with Shelby Talcott from the conservative Daily Caller following his town hall event in Cincinnati. The exchange went like this, according to White House transcripts:

"Mr. President, can you clarify what you said about no — that there's no — no one in the Democratic Party is anti-police"' Talcott asked.

"I didn't say that," Biden replied before adding, " I said that that — that is not the Democratic Party's position. I'm the Democratic Party; I am President. So is the Speaker of the House and so is the –- the Majority Leader. We are not defunding the police."

"Okay," she replied before asking, "And are there people who — in the Democratic Party, who want to defund the police?"

"Are there people in the Republican Party who think we're sucking the blood out of kids?" Biden shot back. His response left Talcott fumbling as Biden stared then turned on his heel and walked away.

Biden's comments has since infuriated conservatives -- a sampling of which can be seen below:
