After spring storms tore through the Dallas-Forth Worth area last Monday evening, social media lit up with photos of chunks of hail the size of golf balls, tennis balls and even softballs and the damage they caused to windows, roofs and cars. Such sizable hail — the largest of which was reported at 4.25 inches in diameter — isn’t unusual in this region, which is part of what you might call “Hail Alley.” But climate scientists say the warming of...

A new study finds humans were virtually the main cause of global warming since 1950, using an alternative statistical model. (Mario Tama/Getty Images) A new study says climate change is virtually all of our fault. Scientists utilizing new statistical methods have calculated that most of the observed warming of the planet between 1951 to 2010 was attributable to "anthropogenic forcings" — i.e. manmade greenhouse gaseswith a "very limited contribution from natural forcings." The report entitled, "A new statistical approach to...

It's been more than 1,000 years since the last time Mount Paektu erupted– but that last eruption was one of the largest in recorded history. That 9,000-foot volcano, which straddles the border between North Korea and China, has been waking up. And that volcano is responsible for bringing the North Korea and the Western world together for a surprising scientific collaboration. Mount Paektu's infamous "Millennium eruption" occurred around 946 A.D., the Washington Post reports, and its destruction was legendary. "It's...

Meteorologist Kait Parker talks about a new study that puts the blame on humans for the climate change that has occurred since the mid-twentieth century. ...

We knew coral bleaching was a serious issue in the Great Barrier Reef, but the scope of just how widespread it was has been unclear — until now. Extensive aerial surveys and dives have revealed that 93 percent of the world’s largest reef has been devastated by coral bleaching. The culprit has been record-warm water driven by El Niño and climate change that has cooked the life out of corals. The unprecedented destruction brought leading reef scientist Terry Hughes, who...

A dead crab is seen in a piece of marsh ravaged by the effects of the BP oil spill on April 17, 2011, in Ocean Springs, Mississippi, a year after the devastating incident. The spill occurred after the Deepwater Horizon rig exploded on April 20, 2010, killing 11 workers and dumping millions of barrels of oil into the Gulf of Mexico. Already known as the worst offshore oil spill in U.S. history, the 2010 BP Deepwater Horizon disaster was even...

It may seem harmless, but this little goldfish can have a big impact on the ecosystem. (iStock/Laures) We know invasive species can be a real issue for local ecosystems, but did you ever think that one of the most common pets across North America could be the culprit? If you've ever thought about putting your goldfish back in its wild home, or flushing it down a porcelain path, officials in Canada have a message for you: you may think it's...

The image above shows the mouth of the Amazon River where it empties into the Atlantic Ocean. Captured by NASA on June 10, 2002. (Jacques Descloitres, MODIS Land Rapid Response Team, NASA/GSFC) As coral bleaching continues to strain reef communities across the globe, an international team of researchers has stumbled across a promising, 600-mile-long discovery. Starting at the mouth of the Amazon river, a sponge and coral reef sprawls across more than 3,600 square miles of ocean floor, according to...

In 1986, a nuclear explosion changed life forever in Pripyat, Ukraine. The Chernobyl disaster dumped radiation across Europe, contamination affecting life there as we know it– or so we thought. As the decades have passed, humans still stay away from the Chernobyl Exclusion Zone (CEZ), the 834-square-mile radius around the Chernobyl Nuclear Power Station. But animals have returned. And a new study shows that they're thriving. Using remote cameras in the Polesie State Radioecological Reserve, researchers captured images of animals...

Scientists believe a hidden lake could be hiding underneath Antarctica, according to information presented at the European Geosciences Union meeting last week. (Stewart Jamieson/Durham University) Could a secret lake be lurking beneath the icy exterior of Antarctica? During a European Geosciences Union meeting in Vienna last week, scientists suggested the existence of a heretofore unknown massive subglacial lake,according to a report from the New Scientist. The researchers based their claims off of satellite imagery, in which they recognized "grooves" which...
