Will Global Warming Benefit Civilization?

Environmental Protection Agency head Scott Pruitt suggests that global warming isn’t necessarily “a bad thing” because “humans have most flourished during times of … warming.” But recent years have been the warmest humans have seen over at least the last millennium.

Obama’s Record on Toxic Cleanups

Environmental Protection Agency head Scott Pruitt criticized former President Barack Obama for leaving “us with more Superfund sites than when he came in.” This is misleading for multiple reasons.

Did Air Quality Improve Under Obama?

EPA head Scott Pruitt criticized former President Barack Obama for leaving 40 percent of Americans with air quality that doesn’t meet EPA standards. But a report Pruitt’s office cited as evidence said there had been a “major improvement” in air quality under Obama.

Will Paris Have a ‘Tiny’ Effect on Warming?

President Donald Trump and his top environmental official said the Paris Agreement would reduce the global average temperature by only 0.2 degrees Celsius. Former Vice President Al Gore said that’s “not true.” Who’s right?

Gore and Pruitt Debate Paris Targets

Former Vice President Al Gore and Environmental Protection Agency head Scott Pruitt made competing claims about whether the U.S. could have changed its emissions targets under the Paris Agreement, instead of pulling out of the deal. Legal experts side with Gore, who claimed the targets could have been changed.

Scott Pruitt and Coal Jobs

The Environmental Protection Agency head said that the “coal sector” added 7,000 jobs in May and “almost 50,000 jobs” since the fourth quarter of last year. But the Bureau of Labor Statistics reports an increase of just 400 coal mining jobs in May and 1,300 since December.

Pruitt on Climate Change, Again

The head of the EPA told CNBC that he “would not agree” that “human activity,” or carbon dioxide emissions, is the “primary contributor” to global warming. But scientists say it’s “extremely likely” that human activity is the main cause of warming since the mid-20th century.

Precision in Climate Science

A number of President Trump’s cabinet members have said that scientists cannot precisely measure climate change nor the impact of human activity on climate change. That’s not accurate.
