Thousands of years ago, carbon gases trapped on the seafloor escaped, causing drastic warming that helped end the last ice age. A scientist says climate change could cause this process to repeat.
Why was one gene mutation that affects hair, teeth, sweat glands and breasts ubiquitous among ice age Arctic people? New research points to the advantage it provided for ancestors of Native Americans.
Bed bugs make us shudder and cringe. So arm yourself with the courage to learn about the biology and successes of Cimex lectularius – as well as the ways to get rid of it.
The last ice age locked atmospheric carbon dioxide into oceans, which has major implications for how the oceans and carbon dioxide may be linked in the future.
Large birds once lived across Australia, only to become extinct around the time that giant marsupials and other megafauna died out during the Pleistocene “ice ages”.
Could sea levels really rise by several metres this century. Probably not, although this century’s greenhouse emissions could potentially set the stage for large rises in centuries to come.
