A relentless series of ‘rivers in the sky’ is creating extreme conditions across the state, but a role for climate change is unclear Not again! Earlier this week, California was battered by heavy rain, strong winds and thick snow — the latest in a seemingly unending procession of strong storms. Wild weather has afflicted the previously drought-stricken state for three months, resulting in devastating floods, paralysing blizzards and dozens of deaths. Data released Thursday show that the snowpack is the biggest on record. Nature spoke to atmospheric and climate scientists about what’s driving the surge in wet weather and what the state could look like in a warmer future. Why are so many storms hitting California? California’s recent parade of storms is driven by atmospheric rive...

A powerful arctic blast swept into the U.S. Northeast on Friday, threatening to push temperatures to record lows in many spots, including New Hampshire's Mount Washington, where the wind chill could drop to -110 degrees Fahrenheit (-79 Celsius), forecasters said. The National Weather Service said in an advisory that the mass of frigid air would keep temperatures at life-endangering levels through Saturday, warning of "extremely dangerous" conditions from the "short-lived blast." Boston and Worcester, the two largest cities in New England, were among the school districts to close on Friday as administrators worried about the risk of hypothermia and frostbite as children waited for buses or walked to school. People walk in Washington Square Park in Manhattan as bitter cold temperat...
Read MoreExtreme cold, travel chaos: Woes from deadly storm continue The deep freeze from a deadly winter storm that walloped much of the United States will continue into the week as people in western New York deal with massive snow drifts that snarled emergency vehicles and travelers across the country see canceled flights and dangerous roads. Road and utility crews faced the task on Monday of digging out and restoring some normalcy around Buffalo, New York, where a blizzard considered the area's worst in 45 years buried snow plows, stranded motorists in cars and killed at least 13 people.

Read MoreJust months after enduring floods that destroyed crops and submerged entire communities, thousands of families in the Brazilian Amazon are now dealing with severe drought that, at least in some areas, is the worst in decades. The low level of the Amazon River, at the center of the largest drainage system in the world, has put dozens of municipalities under alert. The fast-decreasing river water level is due to lower-than-expected rainfall during August and September, according to Luna Gripp, a geosciences researcher who monitors the western Amazon’s river levels for the Brazilian Geological Survey.

Read MoreNew Zealand’s Tūroa ski area is usually a white wonderland at this time of year, its deep snowpack supporting its famed spring skiing. This season, it’s largely a barren moonscape, with tiny patches of snow poking out between vast fields of jagged volcanic boulders. The ski area was forced to close for the season this week, three weeks earlier than planned. Rain repeatedly washed away the snow, and the ski area’s 50 snowmaking machines proved no match against balmy temperatures. Climate change appears to be a significant factor, after New Zealand experienced its warmest winter on record — for the third year in a row.

Read MoreThe intensifying crisis facing the Colorado River amounts to what is fundamentally a math problem. The 40 million people who depend on the river to fill up a glass of water at the dinner table or wash their clothes or grow food across millions of acres use significantly more each year than actually flows through the banks of the Colorado. In fact, first sliced up 100 years ago in a document known as the Colorado River Compact, the calculation of who gets what amount of that water may never have been balanced.

Read MoreThe eastern Mediterranean and Middle East are warming almost twice as fast as the global average, with temperatures projected to rise up to 5 degrees Celsius (9 degrees Fahrenheit) by the end of the century if no action is taken to reverse the trend, a new report says. The region will experience “unprecedented” heat waves, more severe and longer-lasting droughts and dust storms and rainfall shortages that will “compromise water and food security” for the region’s 400 million people, according to a summary of the report released Tuesday. The eastern Mediterranean and the Middle East are more susceptible to warming trends because of their unique natural characteristics, like large desert expanses and lower water levels, the study said.

Read MoreParts of northern Texas, mired in a drought labeled as extreme and exceptional, are flooding under torrential rain. In a drought. Sound familiar? It should. The Dallas region is just the latest drought-suffering-but-flooded locale during a summer of extreme weather whiplash, likely goosed by human-caused climate change, scientists say. Parts of the world are lurching from drought to deluge. The St. Louis area and 88% of Kentucky early in July were considered abnormally dry and then the skies opened up, the rain poured in biblical proportions, inch after inch, and deadly flooding devastated communities. The same thing happened in Yellowstone in June. Earlier this month, Death Valley, in a severe drought, got a near record amount of rainfall in one day, causing floods, and is still in...
Read MoreDeaths from widespread flooding in Pakistan topped 1,000 since mid-June, officials said Sunday, as the country’s climate minister called the deadly monsoon season “a serious climate catastrophe.” Flash flooding from the heavy rains has washed away villages and crops as soldiers and rescue workers evacuated stranded residents to the safety of relief camps and provided food to thousands of displaced Pakistanis.

Read MoreWhat’s considered officially “dangerous heat” in coming decades will likely hit much of the world at least three times more often as climate change worsens, according to a new study. In much of Earth’s wealthy mid-latitudes, spiking temperatures and humidity that feel like 103 degrees (39.4 degrees Celsius) or higher -- now an occasional summer shock — statistically should happen 20 to 50 times a year by mid-century, said a study Monday in the journal Communications Earth & Environment. By 2100, that brutal heat index may linger for most of the summer for places like the U.S. Southeast, the study’s author said.
