Icebergs once drifted to Florida, new climate model suggests
Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, oceanographer Alan Condron of the University of Massachusetts Amherst ...
NASA mission finds widespread evidence of young lunar volcanism
NASA's Lunar Reconnaissance Orbiter (LRO) has provided researchers strong evidence the moon's volcanic activity slowed gradually instead of stopping abruptly a billion years ago.
Solar dimming caused by air pollution increases river-flows
A study published in Nature Geoscience shows that air pollution has had a significant impact on the amount of water flowing through many rivers in the northern hemisphere.

Salt marsh plants key to reducing coastal erosion and flooding
(Phys.org) —The effectiveness of salt marshes – wetlands which are flooded and drained by tides – in protecting coastal areas in times of severe weather has been quantified in a study by researchers ...
While the Arctic is melting the Gulf Stream remains
The melting Arctic is not the source for less saline Nordic Seas. It is the Gulf Stream that has provided less salt.
How carbon budgets can change climate negotiations
(Phys.org) —This week in New York, United Nations Secretary General Ban Ki Moon is hosting a Climate Summit. The Summit aims to 'catalyse action' on climate change among the 120 or so Heads of State in ...
World greenhouse emissions threaten warming goal
Emissions of greenhouse gases are rising so fast that within one generation the world will have used up its margin of safety for limiting global warming to 2°C (3.6°F), an international team of scientists ...

How ancient impacts made mining practical
About 1.85 billion years ago, in what would come to be known as Sudbury Canada, a 10 kilometer wide asteroid struck with such energy that it created an impact crater 250 kilometers wide. Today the chief industry of Sudbury ...
