Darkening of the Greenland Ice Sheet is projected to continue as a consequence of continued climate warming, according to experts....

Repeated marine predator evolution tracks changes in ancient and Anthropocene oceans

This item was filled under Climate
Scientists synthesized decades of scientific discoveries to illuminate the common and unique patterns driving the extraordinary transitions that whales, dolphins, seals and other species underwent as they moved from land to sea. Drawing on recent breakthroughs in diverse fields such as paleontology, molecular biology and conservation ecology, their findings offer a comprehensive look at how life in the ocean has responded to environmental change from the Triassic to the Anthropocene....

Wind bursts strongly affect El Nino severity

This item was filled under Climate
A new study finds that prolonged wind bursts originating in the western Pacific can have a strong effect on whether an El Nino event will occur and how severe it is likely to be. The paper also identifies three distinct varieties of El Nino, and explains how these westerly wind bursts can determine which variety will take shape. The findings should help refine future predictions of these global-scale climate events....

Iceberg armadas not the cause of North Atlantic cooling

This item was filled under Climate
Armadas of icebergs were probably not the cause of abrupt episodes of cooling in the North Atlantic over the past 440,000 years, according to new research....

Bone eating worms dined on marine reptile carcasses

This item was filled under Climate
A species of bone-eating worm that was believed to have evolved in conjunction with whales has been dated back to prehistoric times when it fed on the carcasses of giant marine reptiles....

New method relates Greenland ice sheet changes to sea-level rise

This item was filled under Climate
Early schemes to model the Greenland and Antarctic ice sheets and their impact on sea levels failed to accurately account for changes caused by snowfall and snow melt. These changes depend on ice sheet elevation and region. Researchers developed a new method that includes the effects of elevation and region....

Giant sea lizards in the age of dinosaurs: A new beginning for baby mosasaurs

This item was filled under Climate
They weren't in the delivery room, but researchers have discovered a new birth story for a gigantic marine lizard that once roamed the oceans. Thanks to recently identified specimens, paleontologists now believe that mighty mosasaurs -- which could grow to 50 feet long -- gave birth to their young in the open ocean, not on or near shore....

Panama debate fueled by zircon dating

This item was filled under Climate
New evidence by geologists dates the closure of an ancient seaway at 13 to 15 million years ago and challenges accepted theories about the rise of the Isthmus of Panama and its impact on world climate and animal migrations....
