    Warming’s role in extreme weather quantified

    Scientists have long suspected that some surges in extreme weather — from devastating droughts to thrashing superstorms — are caused by global warming. And now scientists have numbers to support that idea.

    About 75 percent of extreme heat spikes and 18 percent of extreme precipitation over land worldwide can be blamed on this largely human-driven climate change, researchers...

    Driving Curiosity to discovery

    Clara Ma, who in 2009 won an essay contest to name NASA’s new Mars rover, named it Curiosity. “Curiosity,” the young student wrote, “is an everlasting flame that burns in everyone’s mind....

    Monster storm dominates view from space station

    Looking down from 400 kilometers above Earth, astronauts aboard the International Space Station couldn’t help but gawk at a huge typhoon churning in the Western Pacific. On March 31, European Space Agency astronaut Samantha Cristoforetti captured this photo of Typhoon Maysak at near-peak strength as it drifted toward the Philippines.

    Maysak was the record-breaking second major cyclone to...

    Weather forecasting is getting a high-speed makeover

    In late January, a massive snowstorm drifted toward New York City. Meteorologists warned that a historic blizzard could soon cripple the Big Apple, potentially burying the city under 60 centimeters of snow overnight. Governor Andrew Cuomo took drastic action, declaring a state of emergency for several counties and shutting down the city that never sleeps. For the first time in its 110-year...

    Onshore hurricanes in a slump

    No major hurricanes have slammed into the coast of the United States since Hurricane Wilma in 2005. The gap in these hurricanes making landfall is the longest in recorded history and is incredibly rare, researchers report.

    Many hurricanes in recent years have reached Category 3 or above while out to sea, but...

    Canadian glaciers face drastic demise

    The Great White North may lose its glaciers faster than previously thought. A detailed physics simulation of how glaciers melt in a warming world show that Western Canada’s glaciers will shed 70 percent of their ice by 2100 relative to their 2005 volumes, researchers report online April 6 in Nature Geoscience. That level...

    Eggs and other land foods won’t feed polar bears

    Polar bears are in for some change. Their Arctic sea ice homes are quickly disappearing. There’s some research showing that polar bears will be OK when the ice is all gone and they are forced to live life completely on land. For example, Linda J. Gormezano, an ecologist at the American Museum of Natural History in New York City reported last year that,...

    Fewer cold snaps in the forecast

    Bitter bouts of unusually cold days will become less frequent in much of the Northern Hemisphere as the planet warms, two new studies suggest.

    Some scientists had suggested that winter cold snaps would become more common in the future as Arctic warming caused frigid polar winds to waver and dip southward. But that wind waviness is minor compared with other expected climate changes,...
