Federal scientists have confirmed that 2020 basically tied with 2016 for the hottest year recorded since 1880. The Earth is about 2 degrees Fahrenheit warmer today than it was in the mid-20th century. Scientists warn that humans must keep global temperatures from rising more than about 3 degrees Fahrenheit in order to avoid the most catastrophic effects of climate change.

Two NASA astronauts are back on Earth after their space capsule splashed down in the Gulf of Mexico, off the coast of Pensacola, Fla.

The last time any NASA astronauts came home by splashing down was in 1975 — and back then, they were in an Apollo space vehicle. This time, the astronauts were in a white, bell-shaped capsule owned by SpaceX.

Where there was a white ice cap, there are now brown blotches of land; melted snow and ice have created ponds of water. Those are the effects of the recent record high temperatures in Antarctica, according to NASA, which on Friday released stunning before-and-after satellite images of the northern Antarctic Peninsula.

Last year was the second hottest on record globally, according to the latest climate data collected by the National Oceanic and Atmospheric Administration and NASA.

It's the latest confirmation that the Earth is steadily getting hotter — the planet has already warmed about 1.8 degrees Fahrenheit (or almost 1 degree Celsius) compared with in the mid-20th century — and that robust greenhouse gas emissions are causing global warming to continue unabated.
