Interpreting snow depth records from past decades is as much art as science. Even into the 1990s, Soviets on Arctic drifting sea ice used meter sticks and handwritten logs to record snow depth.…

Between Greenland and Spitsbergen, scientists have found the scours on the sea bed left behind by gigantic icebergs - about three times the height of the Empire State Building. The five lineaments,…

As the complex story of climate change unfolds, many of the forecasts are grim, but there are exceptions - the lowest-oxygen environments in the ocean would get now get worse, they may improve if…

Mercury is a naturally occurring element and a part of human enterprises like burning coal and making cement and compact fluorescent light bulbs. Knowing how much of both natural and unnatural…

Warming temperatures are causing Arctic lakes to release methane, a greenhouse gas that has 23X the short term warming effect of CO2, it has been said. A new paper in Nature found that Siberian lakes…

As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before…

Two new papers postulate that there will be a water crisis by 2040. Not because of population, but because of current energy and power solutions.  And they believe solar and wind power is the…

8 of the top 10 U.S. cities that have seen an increase in nuisance flooding, which causes road closures, overwhelmed storm drains and compromised infrastructure, are on the East Coast, according to a…

There's a concern that global warming may push Earth's climate system past a "tipping point," where rapid melting of ice and further warming may become irreversible. It's a hotly debated conjecture…

It sounds like it should be easy enough to know if ice is growing or retreating, but it really isn't.  Antarctic sea ice has been expanding, we are told, while Arctic sea ice is retreating, both…
