Synchronization of North Atlantic North Pacific preceded abrupt warming end of ice age
2014/8/14
Scientists have long been concerned that global warming may push Earth’s climate system across a “tipping point,” where rapid melting of ice and further warming may become irreversible – a hotly debat...
There is growing scientific concern that corals could retreat from equatorial seas and oceans as the Earth continues to warm, a team of international marine researchers warned today.
As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winter...
