Global warming is abruptly redrawing parts of Antarctica’s coastline, as ice shelves collapse into the sea.

We all know that climate is either going to change, or is already doing so, as a result of human activities changing the atmosphere's composition and its land surface.

March 15, 2016One foggy spring morning just after a hard rain, Park Williams was tromping through the woods deep in Arkansas’ Ozark Mountains. Toiling down a steep slope, he supposedly was keeping a simultaneous eye out for rattlesnakes, copperheads, poison ivy and big old trees. Williams seemed mostly focused on the trees, though; attention to the other stuff was just slowing him down. Williams studies how forests react to changes in climate, and the Ozarks’ deeply dissected hills and hollers are a kind of ground zero for this.

As humans continue to heat the planet, a northward shift of Earth’s wind and rain belts could make a broad swath of regions drier, including the Middle East, American West and Amazonia, while making Monsoon Asia and equatorial Africa wetter, says a new study in Proceedings of the National Academy of Sciences
April 22, 2013Fueled by industrial greenhouse gas emissions, Earth’s climate warmed more between 1971 and 2000 than during any other three-decade interval in the last 1,400 years, according new regional temperature reconstructions covering all seven continents. This period of manmade global warming, which continues today, reversed a natural cooling trend that lasted several hundred years, according to results published in the journal Nature Geoscience by more than 80 scientists from 24 nations analyzing climate data from tree rings, pollen, cave formations, ice cores, lake and ocean sediments, and historical records from around the world.

Scientists examining evidence across the world from New Jersey to North Africa say they have linked the abrupt disappearance of half of earth’s species 200 million years ago to a precisely dated set of gigantic volcanic eruptions. The eruptions may have caused climate changes so sudden that many creatures were unable to adapt—possibly on a pace similar to that of human-influenced climate warming today. The extinction opened the way for dinosaurs to evolve and dominate the planet for the next 135 million years, before they, too, were wiped out in a later planetary cataclysm.

In the first statewide climate change outlook for New York, scientists say that the state may suffer disproportionate effects in coming decades compared with other regions, due to its geography and geology. The report paints a harsh picture, including possible extreme temperature and sea-level rises, downpours, droughts and floods. The changes are projected to affect nearly every region and facet of the economy by the 2080s, from ski resorts and dairy farms to New York City’s subways, streets and businesses.

Dec 10, 2007--Scientists from Columbia University’s Lamont-Doherty Earth Observatory will report this week on vital topics including new evidence of the effects of climate change; technologies to confront it; studies of eastern U.S. earthquake risk; and previously unseen inner workings of the deep polar ice caps. The reports will be presented at the fall 2007 American Geophysical Union (AGU), the largest earth-sciences gathering in the world, Dec. 10-14 in San Francisco.

The retreat of a massive ice sheet that once covered much of northern Europe has been described for the first time, and researchers believe it may provide a sneak preview of how present-day ice sheets in Greenland and Antarctica will act in the face of global warming.
