Rivers melt Arctic ice, warming air and ocean

A new study shows that increased heat from Arctic rivers is melting sea ice in the Arctic Ocean and warming the atmosphere.

“Climate Change” is greening the Arctic – and this is bad?

From NASA Goddard:Warming Temperatures are Driving Arctic Greening As Arctic summers warm, Earth’s northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth. “The Arctic tundra is one of the coldest…

Greenland Ice CO2 – Chemical Reactions or Natural Variability?

Guest Post By: Renee Hannon IntroductionThis post examines whether CO2 measurements in Greenland ice cores demonstrate natural variability as an alternative hypothesis to in-situ chemical reactions. Twenty years ago, scientists theorized Greenland ice core CO2 data were unreliable because CO2 trapped in air bubbles had potentially been altered by in-situ chemical reactions. This theory was…

Alternative resupply plan for RV Polarstern now in place

Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research Thanks to the support of additional German research vessels, the MOSAiC expedition will continue, despite the coronavirus pandemic. The new team will start in May. Despite the current challenges, the MOSAiC expedition will continue. After many national borders were closed in response to the coronavirus…

How horses can save the permafrost

New mitigation strategy bears great potential University of Hamburg Permafrost soils in the Arctic are thawing. As they do, large additional quantities of greenhouse gases could be released, accelerating climate change. In Russia, experiments are now being conducted in which herds of horses, bison and reindeer are being used to combat this effect. A study…
