If you are interested in sea level rise news, you have a busy week. First we learn from a Nature Climate Change publication that the Greenland ice sheet is already gone. Then earlier today two studies published in Environmental Research … Continue reading
The most-quoted climate sensitivity range (IPCC 4AR) suggests a median temperature response to a doubling of the atmospheric CO2 concentration of 3 degrees Celsius – and a 66 percent probability range warming under CO2-doubling will be somewhere between 1.5 and … Continue reading
In our first ice age riddle a couple of days ago we looked at the link between CO2 rise and ice retreat, after the last ice age had reached its max, some 18,000 years ago.
During the Earth’s ice ages the Pacific Ocean stored large amounts of carbon, which for some reason it released again close to the last glacial period’s end, warming the world and melting most of the icecaps. That is how the … Continue reading
Glacials and interglacials on the northern and southern hemisphere somehow do not seem to correspond. This has led to a ‘thermal bipolar seesaw theory,’ whereby an off-mode in the thermohaline circulation leads to an ice age in Europe, but excess … Continue reading
Researchers of Utrecht University say the Greenland ice sheet may be more stable now than during the Eemian, the previous interglacial period, which lasted from 130,000-114,000 years BP. It turns out back then Arctic insolation was bigger – although still … Continue reading
