Tipping points are real: Gradual changes in CO2 levels can induce abrupt climate changes

Fri, 23 Jun 2017 10:04:14 EDT ~ During the last glacial period, within only a few decades the influence of atmospheric CO2 on the North Atlantic circulation resulted in temperature increases of up to 10 degrees Celsius in Greenland -- as indicated by new climate calculations. Find out more...

Ocean predicts future northwestern European and Arctic climate

Wed, 21 Jun 2017 10:01:58 EDT ~ There is a clear potential for practical and useful predictions of northwestern European and Arctic climate based on the state of the ocean, new research indicates. Find out more...

Wave beams mix and stir the ocean to create climate

Tue, 20 Jun 2017 11:42:10 EDT ~ Waves deep within the ocean play an important role in establishing ocean circulation, arising when tidal currents oscillate over an uneven ocean bottom. The internal waves generated by this process stir and mix the ocean, bringing cold, deep water to the surface to be warmed by the sun. Investigators now explain how to tell which way internal waves will go. The proposed theory unifies several previously understood explanations of wave propagation. Find out more...

Great opportunities for marine research with new underwater vehicle

Tue, 20 Jun 2017 09:45:45 EDT ~ An autonomous underwater vehicle offers promise for advanced marine research use. This will make it possible to conduct detailed studies of the seabed at great depths and track the climate thousands of years back in time, say researchers. Find out more...

Chemistry of sea spray particles linked for first time to formation process

Mon, 19 Jun 2017 15:15:28 EDT ~ For the first time, researchers have identified what drives the observed differences in the chemical make-up of sea spray particles ejected from the ocean by breaking waves. Find out more...

Scientists throw light on mysterious ice age temperature jumps

Mon, 19 Jun 2017 12:58:22 EDT ~ Scientists believe they have discovered the reason behind mysterious changes to the climate that saw temperatures fluctuate by up to 15C within just a few decades during the ice age periods. Find out more...

Japanese slow earthquakes could shed light on tsunami generation

Thu, 15 Jun 2017 14:27:30 EDT ~ Understanding slow-slip earthquakes in subduction zone areas may help researchers understand large earthquakes and the creation of tsunamis, according to researchers who used data from instruments placed on the seafloor and in boreholes east of the Japanese coast. Find out more...

Widespread snowmelt in West Antarctica during unusually warm summer

Thu, 15 Jun 2017 08:46:01 EDT ~ An area of West Antarctica more than twice the size of California partially melted in 2016 when warm winds forced by an especially strong El Nino blew over the continent. Find out more...

Polar bears' declining mercury levels likely due to climate-related shifts

Wed, 14 Jun 2017 09:18:20 EDT ~ To understand how human activities are affecting the planet, scientists often study the health of animals in the wild. Now a new study finds that the levels of mercury in some polar bears are declining. But rather than heralding a drop in mercury in the environment, the decrease could indicate how climate change has led the animals to shift foraging habits, which has affected their diets and weight.

Large Canadian Arctic climate change study cancelled due to climate change

Tue, 13 Jun 2017 15:06:51 EDT ~ The Science Team of the Canadian Research Icebreaker CCGS Amundsen has cancelled the first leg of the 2017 Expedition due to complications associated with the southward motion of hazardous Arctic sea ice, caused by climate change. Find out more...
