As President Donald Trump's administration looks to reverse a cornerstone finding that climate change endangers human health and welfare, scientists say they need to look around because it’s obvious how bad global warming is and how its getting worse.

Scientists say global heat that inched into worrisome new territory this week is a clear example of how pollutants released by humans are warming their environment.

A new study using artificial intelligence finds that the world will likely warm a few more tenths of a degrees within the next 10 to 12 years and breach a key climate change threshold.

A new accounting of carbon dioxide emissions finds that heat-trapping gas pollution from fossil fuels went up about 1% more than last year.

Climate action has become a much discussed topic around the world, but can individual actions make a difference in how much carbon dioxide is emitted on an international scale.

Many climate scientists share a sense of optimism with professionals in other tough jobs like emergency room doctors and researchers who study Alzheimer’s Disease even as they chronicle a world losing its protective balance with the sun.

WASHINGTON, DC For more than two years President Donald Trump has talked about pulling the United States out of the landmark Paris climate agreement . In the Paris agreement, nearly 200 countries set their own national targets for reducing or controlling pollution of heat-trapping gases. Trump has been promising to pull out of the Paris deal since 2017, often mischaracterizing the terms of the agreement, which are voluntary. There is no massive wealth transfer," said Climate Advisers CEO Nigel Purvis, who was a lead State Department climate negotiator in the Clinton and George W. Bush administrations. Formally getting out of the Paris agreement is bad, but at this point after years of rhetoric is more symbolic than anything, said Georgia Tech climate scientist Kim Cobb.
