Fifty-six million years ago, about 10 million years after the dinosaurs went extinct, something strange happened to our planet.It got hot. Really hot.Hotter than it had ever been since the Earth formed a few billion years earlier.Carbon signatures in the geological record show that global temperature surged 5 to 8 degrees Celsius within 10,000 years.They also indicate that the planet’s temperature remained elevated for an additional 170,000 years before returning to normal.Scientists describe t..>> view originalMysterious humpback whale 'super-groups' baffle global scientists
Humpback whales have long been known as the solitary giants of the animal kingdom, preferring alone time to social interaction. In an unexpected turn of events, the majestic creatures have begun congregating in "super-groups" of up to 200 animals off the coast of South Africa. Researchers are baffled by the behavior, as humpbacks typically flock together in groups no larger than 20. "I've never seen anything like this," Ken Findlay told New Scientist. Findlay led a team of researchers from the..>> view originalChina's 'airpocalypse' a product of climate change, not just pollution, researchers say
China’s notorious smog problem may have been worsened by climate change in the polar regions, according to a study published in the United States on Wednesday. According to the study published in the US journal Science Advances, the findings may provide some clues why China’s smog problem has failed to ease despite cuts in pollution-causing emissions. When analysing the impact of global warming on regional pollution, researchers from Georgia Institute of Technology found that the level of haza..>> view originalTV broadcast satellite launched aboard Falcon 9 rocket

Indonesian authorities said Wednesday that the captain could face charges and spend time in prison, despite the company, Noble Caledonia Charitable Trust, covering the environmental damage via insurance.

(Matt Harding/AP) President Trump’s first federal budget seems to make good on his campaign promises to shift NASA’s focus away from Earth and toward space. But it doesn’t reveal where he thinks the agency should be headed — to Mars, the moon or elsewhere. Overall, Trump would shrink funding for NASA slightly, to $19.1 billion from about $1..>> view originalHungry, hungry spiders eat more than 400 million tons of insects a year
March 15, 2017 —In his 1958 book "The World of Spiders," British arachnologist William Bristowe made a jarring speculation: The weight of the insects killed each year by Britain's spiders exceeded the weight of Britain's total human population.One of that book's readers, Martin Nyffeler, went on to pursue a career in arachnology, and has just found that Mr. Bristowe may have been on to something. In a new study, he and other scientists have estimated that spiders kill 400 million to 800 million..>> view originalA Sea Change for Climate Coverage

About 500,000 years ago, different members of the Homo genus spread throughout Europe and Asia, some of which evolved into the Neanderthals, the closest extinct relative of modern humans. From what particular hominin species the Neanderthals evolved from, however, has been the subject of debates. Now, a newly discovered skull found in the cave of Aroeira in Portugal offers clues that may help solve the mystery of the Neanderthal ancestry. 400,000-Year-Old Skull The skull represents the westernm..>> view original
