In a bizarre experiment, scholars declared that survivors of one of California's annual wildfires instead suffered PTSD due to climate change.

It was a small group, 27 who had been near a fire in 2018, 21 who had seen smoke, and 27 in the control group. Participants had EEG brain scans taken while they engaged in behavior which could provide monetary rewards. The scholars also subjectively scored their Win-Stay behavior, basically how often they sought the highest long-term rewards.
President Donald Trump is about to sign an executive order restarting coal leasing on federal lands while classifying coal as a critical mineral. 

Social media critics, and academics being quoted in media, are declaring the end of the world due to American pollution. Are they correct?
When the Proposition 65 referendum, the Safe Drinking Water and Toxic Enforcement Act of 1986, was being debated, concerns about abuse and high cost were dismissed by the lawyers behind it with the assurance that lawyers wouldn't decide what products would be deemed carcinogens, the state would abdicate that to France's International Agency for Research on Cancer.

Utah wants to be the California of the right-wing; ban things because it matches the politics of their voters and science will be marginalized.(1)
Greenpeace is facing bankruptcy after a $667,000,000 judgment. For the first time ever, the number of U.S. federal employees declined. Democrats have begun to consider they might be wrongly defending terrorists. They even became pro-vaccine for the first time this century. 

The best thing President Donald Trump may have done for science and political sanity is to switch from Democrat to Republican and bring Bobby Kennedy Jr. and Elon Musk along with him. It forced Democrats, who are nearly 90% of career government employees, to suddenly defend things they had opposed for decades.(1)

Like nuclear energy. Which means we could usher in a new Golden Age of Science.
