Watch billions of tons of ice collapse at once: Climate change impact on Greenland

Watch billions of tons of ice collapse at once: Climate change impact on Greenland

World
Perched on a cliff above Greenland’s Helheim glacier, I tried calling my wife in New York on a satellite phone. Before I could leave a message, an explosion broke the arctic silence. More explosions followed. I ran across a muddy tundra to a video camera on a tripod overlooking the glacier and ripped off the trash bag I had used to protect it. I hit record as fast as I could focus. The popping sounds morphed into a low rumble. Over the next half hour, the ice broke apart and a four-mile wide chunk tumbled into the sea in a process called calving - one rarely witnessed on this scale. As a Reuters photographer, I have captured erupting volcanoes, the aftermath of hurricanes and tornadoes, and war, but I have never felt so small. It was a poignant end to a months-long project e...
Coastal wetlands must migrate inland to survive climate change

Coastal wetlands must migrate inland to survive climate change

Science
Sept. 12 (UPI) -- If coastal wetlands are to survive climate change -- and continue to provide a bounty of ecological benefits -- they most move inland, according to a new study. Previous studies have suggested many coastal wetlands are likely to be wiped out by encroaching salt water as global warming accelerates sea level rise. But new analysis suggests many marshes and mangroves could be saved if they were able to move farther inland. That's good news, as wetlands help absorb excess CO2 and serve as a vital buffer against damaging storms and flooding. Some studies have shown wetlands save hundreds of lives and millions of dollars. To better understand the fates of coastal wetlands, an international team of scientists collected and analyzed data from the around the world. Researchers lo...
'Climate change moving faster than we are,' says UN Secretary General

'Climate change moving faster than we are,' says UN Secretary General

Science
UN Secretary General Antonio Guterres has said that if the world doesn't change course by 2020, we run the risk of runaway climate change. Mr Guterres said he was alarmed by the paralysis of world leaders on what he called the "defining issue" of our time.He wants heads of government to come to New York for a special climate conference next September. The call comes amid growing concerns over the slow pace of UN negotiations.Mr Guterres painted a grim picture of the impacts of climate change that he says have been felt all over the world this year, with heatwaves, wildfires, storms and floods leaving a trail of destruction. Corals are dying, he said, the oceans are becoming more acidic, and there are growing conflicts over dwindl...
Buffalo Bills not ready to make QB change yet

Buffalo Bills not ready to make QB change yet

Sports
The Buffalo Bills' offense is a bigger mess than anyone could have imagined, and it was on display Sunday in all its ugliness during a 47-3 loss to the Baltimore Ravens. On a horribly rainy day, the Bills found a way to be even more miserable than the conditions. They managed just 10 first downs and 153 total yards, were 2 of 15 on third down, and averaged just 2.5 yards per play. "Overall, I thought we could have been better in a number of positions," coach Sean McDermott said. "I've got to look at the tape, to be honest with you, to get a better feel and making sure we were in the right spots before I give you a better read-out." The tape won't show anything different from what everyone saw: the worst offensive performance in the NFL in Week 1. And yet that has not moved McDermott ...
Climate change: 'Hothouse Earth' risks even if CO2 emissions slashed

Climate change: 'Hothouse Earth' risks even if CO2 emissions slashed

World
It may sound like the title of a low budget sci-fi movie, but for planetary scientists, "Hothouse Earth" is a deadly serious concept.Researchers believe we could soon cross a threshold leading to boiling hot temperatures and towering seas in the centuries to come.Even if countries succeed in meeting their CO2 targets, we could still lurch on to this "irreversible pathway". Their study shows it could happen if global temperatures rise by 2 deg C.An international team of climate researchers, writing in the journal, Proceedings of the National Academy of Sciences, says the warming expected in the next few decades could turn some of the Earth's natural forces - that currently protect us - into our enemies. Each year the Earth's forests, oceans and land soak u...
