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.

Ten years ago scientists warned the world about how climate change would amplify extreme weather disasters.

A United Nations report says a staggering 143 million people will likely be uprooted over the next 30 years by rising seas, searing temperatures and other climate calamities.

A locked-down pandemic-struck world cut its carbon dioxide emissions this year by 7%, the biggest drop ever, new preliminary figures show. The Global Carbon Project, an authoritative group of dozens of international scientists who track emissions, calculated that the world will have put 37 billion U.S. tons (34 billion metric tons) of carbon dioxide in the air in 2020. Ground transportation makes up about one-fifth of emissions of carbon dioxide, the chief man-made heat-trapping gas. Even with the drop in 2020, the world on average put 1,185 tons (1,075 metric tons) of carbon dioxide into the air every second. Even with emissions expected to rise after the pandemic, scientists are wondering if 2019 be the peak of carbon pollution, LeQuere said.
