Researchers at the University of Arkansas have established a link between climate patterns in the Amazon and large parts of North and South America using a newly developed tree-ring chronolo...
Synchronization of North Atlantic, North Pacific preceded abrupt warming, end of ice age
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...

The origin of the 1500-year climate cycles in Holocene North-Atlantic records
climate cycles Holocene North-Atlantic
2008/11/7
Since the first suggestion of 1500-year cycles in the advance and retreat of glaciers (Denton and Karlen, 1973), many studies have uncovered evidence of repeated climate oscillations of 2500, 1500, an...
Tropical cooling and the onset of North American glaciation
tropical North American glaciation
2008/11/5
We offer a test of the idea that gradual cooling in the eastern tropical Pacific led to cooling of North America and the initiation of glaciation ~3 Myr ago. Using modern climate data we estimate how...
Direct north-south synchronization of abrupt climate change record in ice cores using Beryllium 10
synchronization ice cores Beryllium 10
2008/11/5
A new, decadally resolved record of the 10Be peak at 41 kyr from the EPICA Dome C ice core (Antarctica) is used to match it with the same peak in the GRIP ice core (Greenland). This permits a direct s...
