Environmental News Network: There was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery. New evidence published this week in the leading journal Science shows for the first time that the ocean's overturning circulation slowed during every one of those temperature plunges - at times almost stopping. "People...

Past presents warning on greater warming
2016-07-04 11:14:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate News Network: Greenhouse gases are now being released at a faster rate than during the thermal maximum 56 million years ago. Reconstruction of climate events long before the Ice Ages shows that failure to reduce greenhouse gas emissions could eventually lead to temperatures rising by up to 10 degrees. If the distant past is anything to go by, then climate scientists may have under-estimated the hazards of greenhouse gases, and future global warming could be a lot worse than anybody thought. The calculation...
