Yes, indeed, we’re a couple of days late bringing you the news. But this could be an important update to our Arctic melting coverage. It’s feedback-driven (after all), American and French researchers say.
As a regular of Bitsofscience.org you may recall a publication on ocean warming [between 2003-2010] in Geophysical Research Letters from last July. That one was little-noticed by the world’s media, but now its findings may receive more attention, as an … 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
Since the 1860′s nitrogen additions to the terrestrial biosphere have more than doubled, due to human activities. Since nitrogen is a key nutrient needed for plant growth and therefore used as a fertiliser, the additions have made a drastic increase … Continue reading
The prevailing theory and fear that rising global temperatures could result in permanent El Niño conditions have been called into question by an international research team on the basis of growth rings of prehistoric clams. A transition to a permanent … Continue reading
Here´s why finding out the Gulfstream could be quite stable wouldn´t necessarily be such good news: under continued warming, the positive feedback of increased tundra peat soil CO2 and methane emissions far outweighs the negative feedback of ‘taiga creep’ and … Continue reading
Here’s another climate model study that challenges the Arctic tipping point idea. Arctic melting is still sensitive to temperature rise though and any further increase in atmospheric CO2 will keep translating to further ice loss. According to the new NASA … Continue reading
Computer simulations of the US National Center for Atmospheric Research indicate that the natural Arctic climate variability, like seasonal and annual variations in pressure systems, wind patterns and precipitation or cloud cover, could be larger than previously thought.
A resonating question among climatologists: how will warming affect the El Niño Southern Oscillation?
In March we learned ice sheet formation is two-sided. On Sunday, sipping coffee whilst reading the latest Nature Geoscience, we learned the same might go for ice sheet melting. If so, melting would likely accelerate over this century and sea … Continue reading
