False Climate Security; Human Ancestor Shaped by Climate Change; Greenland Runaway Warming Begun
The oceans may be lulling us into a false sense of climate security. New research casts severe doubt on other work which had oversold the role of natural climate’s ability to halt global warming for the next 15 years.
Early human ancestor shaped by climate change, study says. A broken and fossilized jawbone found poking from the sediment of an East African hill is rewriting a significant chapter of human evolution – and adding weight to the argument that a hot and parched climate guided the development of our ancestors.
Greenland Reels: Climate-Disrupting Feedbacks Have Begun. Greenland is warmer than it has been in more than 100,000 years, and climate-disrupting feedback loops have begun. Since 2000, ice loss has increased over 600 percent, and liquid water now exists inside the ice sheet year-round, no longer refreezing during winter.
