Antarctic Sea Ice Grows as Result of Warming

Antarctic Sea Ice Grows as Result of Warming

The Arctic may be shrinking as the world warms but Antarctic sea ice is expanding. Blame global warming for that, too, say Dutch scientists. The paradox is that increasing temperatures have set in motion a chain of events in the southern seas that have the opposite effect. Engineers call this negative feedback. So do Richard Bintanja and colleague… Read More

Heavy, Dam-Busting Rainstorms To Increase, Study Finds

Boosted by the added moisture from warming air and ocean temperatures, the heaviest precipitation events, of the sort that can cause dams to fail, rivers to spill over their banks, and cities to flood, are likely to become significantly heavier by the end of this century, according to a new study.… Read More

The good news is that U.S. greenhouse gas (GHG) emissions are continuing to decline. “Over the last four years, our emissions of the dangerous carbon pollution that threatens our planet have actually fallen,” said President Obama in his State of the Union address last month. The bad news is the U.S. is exporting its polluting gases, particularly i… Read More

Warming May Mean More Toxic Algae Blooms for Lake Erie

Warming May Mean More Toxic Algae Blooms for Lake Erie

Toxic algae blooms in Lake Erie could come more often and be more intense in coming decades thanks in part to torrential rains intensified by global warming, according to a study published in Monday’s Proceedings of the National Academy of Sciences. Heavy runoff from farmland, say the authors, can carry nutrient-rich fertilizer into the western… Read More
