#TheDonald will be quoting studies from the 1970s next, at that time there were a lot of studies suggesting a #SnowballEarth was a strong possibility, but the strong effects of human activity has more than reversed that cooling trend and general consensus is that on average #Earthclimate will warm.

Earth’s climate flipped rapidly even in an ice-free world • Muser Press Earth’s climate is often thought to require massive ice sheets to flip rapidly between wet and dry states, but new evidence from the deep past suggests

Earth’s climate shifted sharply even in an ice-free greenhouse world. New Nature Communications research links Late Cretaceous wet–dry cycles to slow orbital wobbles, reshaping views of past and future warming.

Have Stellar Flybys Altered Earth's Climate in the Past? If our Solar System seems stable, it's because our short lifespans make it seem that way. Earth revolves, night follows day, the Moon moves through light and shadow, and the Sun hangs in the sky. But...
