Al Gore: Blizzard of 2011 May Be So Fierce Because of Global Warming
By Torie Bosch - AOL NewsIt's the global warming denier's favorite "gotcha": If the planet is heating up, then why are we getting so much snow? (Remember the snickers when the 2009 Copenhagen climate-change summit was interrupted by snowfall?) But Al Gore, patron saint of global warming believers, isn't brooking any of that nonsense. Last week, Bill O'Reilly asked on his Fox News show, "Why has southern New York turned into the tundra?" He also quipped that he had a call out to Gore. Gore has now responded via his blog Al's Journal. "I appreciate the question," he writes. "As it turns out, the scientific community ...
Groundhog Day 2011: Punxsutawney Phil Predicts Quick End to Winter
By Ben Muessig - AOL NewsBummed out by this winter's weather? Well, the worst of it will be over soon -- at least according to a rodent in Pennsylvania. It's the one day of the year when we ignore Doppler radar, mute the weather guy and put our trust in a marmot instead of the weather widgets on our computer screens. Today is Groundhog Day, a great American folk holiday that hinges on a groundhog named Punxsutawney Phil and his shadow. According to tradition, if Punxsutawney Phil climbs out of his burrow on a cloudy day and is unable to see his shadow, it's a sign that spring is on its way. If Feb. 2 is a sunny day ...
It's Cold Now, but 2010 Was Warmest on Record Globally
By Paul Yeager - AOL News(Dec. 16) -- While much of the United States and parts of Europe have been shivering through intense early-season cold, NASA records show that this was the warmest climate year on record. The NASA statistics indicate that the overall global temperature during the climate year (December 2009 through November 2010) was 1.17 degrees Fahrenheit above the 1951-1980 base period, making it the warmest since records began in 1880. All-time record heat occurred in 19 nations in 2010 -- the highest number of national all-time records established in a single year. Kevork Djansezian, Getty ...
Second Arctic Outbreak Hits US; Why Is It So Cold?
By Paul Yeager - AOL News
(Dec. 13) -- The second outbreak of Arctic cold in two weeks has hit the U.S., and residents in much of the eastern two-thirds of the nation will shiver again this week: Temperatures Tuesday morning will range from close to 30 below zero in International Falls, Minn., to near freezing in Miami. While weather extremes are often blamed on either the El Nino or La Nina weather phenomena, it's a lesser-known weather factor, the Arctic Oscillation, that's more responsible for the bitter one-two punch. A "negative" phase of the oscillation occurs when atmospheric pressures are high over the high ...
The World's Lakes Are Heating Up, Study Finds
By J. Richard - AOL News(Nov. 23) -- Scientists have long studied the effects of global warming on the world's oceans, showing that climate change could leave aquatic life gasping for air in oxygen-poor waters for thousands of years to come. Now, NASA researchers say a similarly grim future awaits the Earth's lakes, which have heated up an average of 0.81 degrees Fahrenheit per decade over the past 25 years as a result of climate change. That variation might not seem like a huge deal, but lake ecosystems "can be adversely affected by even small water temperature changes," according to researchers at NASA's Jet ...
Two Decades Later, Hole in the Ozone Layer Still Not Fixed
By Dave Thier - AOL News(Oct. 26) -- Fixing the hole in the ozone layer above Antarctica was supposed to be environmentalists' finest hour. In the late 1970s, an insidious, commonplace group of chemicals (chlorofluorocarbons, or CFCs) was discovered to be causing horrible damage to the ozone layer. Governments were informed, CFCs were banned in 1989, and the day was saved. Unfortunately, it's taking a little while. Lt. Nick Morgan, of the National Oceanic and Atmospheric Administration Commissioned Officer Corps, spends his time in the South Pole, launching into the air balloons containing instruments that can ...
New Supercomputer to Boost Weather Forecasting
By Paul Yeager - AOL News
(Oct. 24) -- Jokes about inaccurate weather forecasts are as popular as jokes about doughnut shops and the police, but advances in satellite data and computers have dramatically improved climate science in the past 50 years. And there will soon be a brand new supercomputer available to government scientists aimed at improving forecasts, whether just a few hours out or decades into the future. The National Oceanic and Atmospheric Administration's recent ribbon-cutting ceremony in Fairmont, W.Va., marked the future home of the NOAA Environmental Security Computing Center (NESCC), a $27.6 ...
NASA: CO2, Not Water Vapor, Causes Global Warming
By Dave Thier - AOL News(Oct. 15) -- The Earth's atmosphere is a complicated place. Somewhere in that swirling, shifting mixture of air, water and other gasses is the key to keeping us earthlings alive -- or to cooking us. Carbon dioxide has always received the most media attention as the leading cause of climate change, and a new study from NASA does more than concur with this assessment: It finds CO2 is overwhelmingly responsible for raising Earth's temperature. Led by Andrew Lacis at the NASA Goddard Institute for Space Studies, the study found that while water vapor and clouds account for 75 percent of the ...
An Inconvenient Whizz? Urine of Ancient Species Proves Useful in Climate Research
By Dave Thier - AOL News(Oct. 12) -- Researchers have used many resources to study historical and future climate change, from larval fish at the bottom of Lake Michigan to ice cores thousands of years old. But nobody has ever published an extensive study examining fossilized animal urine. Until now. An international team of researchers have been looking into crystallized piles of urine from the hyrax, a common mammal in places like Nambia and Botswana, to get clues about how the climate in those areas has changed over thousands of years. The urine, explains Dr. Andrew Carr of England's University of Leicester, ...
Drought Eases in the East but Worsens in the South
By Paul Yeager - AOL News
(Oct. 8) -- Recent heavy rains have greatly improved drought conditions along the Eastern Seaboard, but they're getting worse in the Deep South, a bigger concern heading into a winter when La Nina conditions favor less precipitation than normal. Drought is also a concern for the Desert Southwest and Hawaii. Back-to-back soaking storms in the East last week, which brought record-breaking rainfall to many areas, completely erased what had been a mild to severe long-term drought from southern New York and eastern Pennsylvania south to the eastern Carolinas, including the major cities from ...
