Evidence of Human-Caused Climate Crisis Has Now Reached 'Gold Standard'-Level Certainty, Scientists Say
By Julia Conley
Most Americans now recognize the scientific community's consensus that human activity is fueling the climate crisis, according to polls—but for those who are still unconvinced of the conclusion reached by 97 percent of climate scientists, a new study makes an even more definite assertion.
Scientists at the Lawrence Livermore National Laboratory in California found that the information available can now be classified as "five-sigma"—a standard in the scientific community meaning that there is a one-in-a-million chance that the same data would be observable if humans were not causing the planet to grow warmer through activities like fossil fuel extraction. The classification represents a "gold standard" level of certainty.
"The narrative out there that scientists don't know the cause of climate change is wrong," Benjamin Santer, who led the study, told Reuters. "We do."
Scientists applied the same "five-sigma" measure to research confirming the existence of the Higgs boson subatomic particle in 2012, a finding that was received with applause from the science community and the press.
The report, which was published in the journal Nature Climate Change, builds on the United Nations' Intergovernmental Panel on Climate Change (IPCC) report from 2013, which found that it was "extremely likely" that humans were causing the climate crisis—with a 95 percent chance.
In recent years, although President Donald Trump and other Republican lawmakers have attempted to cast doubt on the scientific consensus that human activity is causing global warming and the climate crisis, the American public has increasingly believed scientists.
In a 2018 survey by the Yale Program on Climate Change Communication, 62 percent of Americans believed that man-made climate change was taking place, versus just 47 percent convinced that was the case just five years earlier.
The Nature Climate Change study also comes on the heels of reports that the melting of ice in Antarctica and the warming of the ocean are both occurring much faster than previously thought; that the last four years have been the hottest on record; and that the warming of the globe could cause clouds to disappear from the sky in the next generation, leading to an 8º Celsius (14.4º Fahrenheit) jump in temperature.
"Humanity cannot afford to ignore such clear signals," the authors of the most recent study wrote in Nature Climate Change.

Global Banks, Led by JPMorgan Chase, Invested $1.9 Trillion in Fossil Fuels Since Paris Climate Pact
By Sharon Kelly
A report published Wednesday names the banks that have played the biggest recent role in funding fossil fuel projects, finding that since 2016, immediately following the Paris agreement's adoption, 33 global banks have poured $1.9 trillion into financing climate-changing projects worldwide.

2018 was a groundbreaking year in the public conversation about climate change. Last February, The New York Times reported that a record percentage of Americans now believe that climate change is caused by humans, and there was a 20 percentage point rise in "the number of Americans who say they worry 'a great deal' about climate change."
England faces an "existential threat" if it does not change how it manages its water, the head of the country's Environment Agency warned Tuesday.

A new analysis revealed Tuesday that over the past two decades heat records across the U.S. have been broken twice as often as cold ones—underscoring experts' warnings about the increasingly dangerous consequences of failing to dramatically curb planet-warming emissions.

Ask any resident of San Francisco about the waterfront parrots, and they will surely tell you a story of red-faced conures squawking or dive-bombing between building peaks. Ask a team of researchers from the University of Georgia, however, and they will tell you of a mysterious string of neurological poisonings impacting the naturalized flock for decades.
The initial cause of the fire was not yet known, but it has been driven by the strong wind and jumped the North Santiam River, The Salem Statesman Journal reported. As of Tuesday night, it threatened around 35 homes and 30 buildings, and was 20 percent contained.
The unanimous verdict was announced Tuesday in San Francisco in the first federal case to be brought against Monsanto, now owned by Bayer, alleging that repeated use of the company's glyphosate-containing weedkiller caused the plaintiff's cancer. Seventy-year-old Edwin Hardeman of Santa Rosa, California said he used Roundup for almost 30 years on his properties before developing non-Hodgkin's lymphoma.
"Today's verdict reinforces what another jury found last year, and what scientists with the state of California and the World Health Organization have concluded: Glyphosate causes cancer in people," Environmental Working Group President Ken Cook said in a statement. "As similar lawsuits mount, the evidence will grow that Roundup is not safe, and that the company has tried to cover it up."
Judge Vince Chhabria has split Hardeman's trial into two phases. The first, decided Tuesday, focused exclusively on whether or not Roundup use caused the plaintiff's cancer. The second, to begin Wednesday, will assess if Bayer is liable for damages.
"We are disappointed with the jury's initial decision, but we continue to believe firmly that the science confirms glyphosate-based herbicides do not cause cancer," Bayer spokesman Dan Childs said in a statement reported by The Guardian. "We are confident the evidence in phase two will show that Monsanto's conduct has been appropriate and the company should not be liable for Mr. Hardeman's cancer."
Some legal experts said that Chhabria's decision to split the trial was beneficial to Bayer, Reuters reported. The company had complained that the jury in Johnson's case had been distracted by the lawyers' claims that Monsanto had sought to mislead scientists and the public about Roundup's safety.
However, a remark made by Chhabria during the trial and reported by The Guardian was blatantly critical of the company.
"Although the evidence that Roundup causes cancer is quite equivocal, there is strong evidence from which a jury could conclude that Monsanto does not particularly care whether its product is in fact giving people cancer, focusing instead on manipulating public opinion and undermining anyone who raises genuine and legitimate concerns about the issue," he said.
Many regulatory bodies, including the U.S. Environmental Protection Agency, have ruled that glyphosate is safe for humans, but the World Health Organization's International Agency for Research on Cancer found it was "probably carcinogenic to humans" in 2015. A university study earlier this year found that glyphosate use increased cancer risk by as much as 41 percent.
Hardeman's lawyers Jennifer Moore and Aimee Wagstaff said they would now reveal Monsanto's efforts to mislead the public about the safety of its product.
"Now we can focus on the evidence that Monsanto has not taken a responsible, objective approach to the safety of Roundup," they wrote in a statement reported by The Guardian.
Hardeman's case is considered a "bellwether" trial for the more than 760 glyphosate cases Chhabria is hearing. In total, there are around 11,200 such lawsuits pending in the U.S., according to Reuters.
University of Richmond law professor Carl Tobias told Reuters that Tuesday's decision showed that the verdict in Johnson's case was not "an aberration," and could possibly predict how future juries in the thousands of pending cases would respond.
