Say, what caused this to happen? This is how you take a perfectly reasonable scientific research project and make it into a doomsday cult piece
Ancient Earth experienced abrupt climate swings without polar ice, study finds
Professor Chengshan Wang of the China University of Geosciences led an international research team examining sediment cores from China’s Songliao Basin from about 83 million years ago in the Late Cretaceous, ScienceDaily reported.
At the time, the planet had very high carbon dioxide levels and almost no polar ice.
Many researchers had tied abrupt climate swings mainly to large ice sheets growing and melting. That view fit the last Ice Age. Greenland warmed by up to 16 degrees Celsius within decades, and repeated pulses of icebergs disrupted circulation in the North Atlantic.
But the new study points to a different mechanism of slow changes in Earth’s orbit and axial wobble.
So, wait, it was totally natural? I didn’t think that was possible, per Cult Of Climastrology dogma
The Late Cretaceous may offer one of the best natural comparisons for a much warmer world.
“During the Late Cretaceous, atmospheric CO2 levels reached about 1,000 parts per million — comparable to projections for the end of this century,” said Michael Wagreich, a paleoclimatologist at the University of Vienna, as reported by ScienceDaily.
If global temperatures continue rising, understanding how climate systems behaved under those conditions before could help scientists better anticipate risks.
