Leading scientists say the idea of blaming global warming on El Nino doesn't look so hot.
Scientists have good reasons to contemplate climate in global terms, but this planetary way of looking at seemingly minor changes in worldwide average temperatures leads the rest of us down a slippery slope. People live in one place or another -- it's regional climate that matters. Perfectly accurate global averages tell us how planet Earth [...]
Out of a year of chaotic weather extremes, climate scientists are beginning to see a pattern.
Airplanes that take off or land at airports where certain atmosphere conditions prevail can pierce mid-level clouds with unusual round shapes that lead to brief showers of snow or rain.
The eastern North Pacific and North Atlantic Oceans set up a see-saw of weather conditions that affect how hurricanes form in both regions.
From freezing cold to pouring rains, this winter may have a topsy-turvy feel to it, but the people who keep their eyes on conditions in the oceans have no doubt about the pattern of powerful storms now blowing in from the Pacific. It has El Niño written all over it. "It's obviously a very strong [...]
A more southerly Pacific jetstream shaped by El Niño leads forecasters to predict a wetter and cooler south and a drier and warmer north across the United States this winter. While the warm sea surface temperatures in the central and eastern Pacific are the strongest signal defining the 2009-2010 winter outlook issued by the Climate [...]
Just when it looked like researchers had figured out the mysterious link between sunspot activity and Earth's weather, along comes another solar surprise: As indicators of the impact of the Sun's activity on the planet, sunspots are not all they have been cracked up to be. Scientists at the National Center for Atmospheric Research and [...]
