NASA’s AIRS Sees Polar Vortex Behind U.S. Big Chill
Published January 2014: The chilling weather phenomenon that hit much of the U.S. in January is explained by scientist Eric Fetzer using data from NASA’s AIRS instrument.
Paul Beckwith: Climate Change Deep Freeze (Polar Vortex, Jet Stream and Sea Ice)
Paul Beckwith, discusses the severity and extent of the North American deep freeze and how it results from fractured jet streams due to climate change.
Polar Vortex to Collapse and Flood Eastern US With Arctic Air
Robert Scribbler: Well, the forecast is in. And it appears we are about to receive yet another helping of winter weather extremes driven by human caused climate change. ECMWF and NOAA models both show mid and upper level warmth increasing over the polar region. This warmth, over the next week, will invade toward the surface, collapsing the…
Wild Weather of the Future (1776 Edition)
By Chris Mooney| Tue Aug. 27, 2013: In this talk, meteorologist and America’s “Science Idol” contest winner Tom DiLiberto gives a forecast of the weather of the future—the weather that will be produced by climate change. While some of the details remain scientifically cloudy—according to DiLiberto, we don’t yet understand what will happen to tornadoes…
Increased Methane emissions from summer Monsoon
Eastern Afghanistan and neighbouring Pakistan have been hit by torrential rain, causing floods which have killed at least 80 people. The region has suffered devastating floods during the monsoon period for the past three years. High methane in North Africa, Middle East and South Asia. The upper tropospheric methane continues to build. The MODIS image…
Ups-and-downs of Indian monsoon rainfall likely to increase under warming
PIK June 20, 2013: Day-to-day rainfall in India might become much more variable due to climate change – potentially putting millions of poor farmers and the country’s agricultural productivity at risk. The Indian monsoon is a complex system which is likely to change under future global warming. While it is in the very nature of…
Cyclone Activity Has Been Intensified in the Arctic
Cyclones are key weather elements that make a major contribution to climate trends and variability, and that also bring intense high-frequency changes in wind, temperature and precipitation. Given the recent dramatic change of the Arctic climate, Arctic cyclone activity has attracted an increasing amount of attention. We investigated the Arctic cyclone activity in the context…
Ozone Levels Drop When Hurricanes Are Strengthening
Hurricanes and Ozone June 11, 2005 Ozone levels drop when a hurricane is intensifying. Xiaolei Zou and Yonghui Wu, researchers at Florida State University found that variations of ozone levels from the surface to the upper atmosphere are closely related to the formation, intensification and movement of a hurricane. They studied ozone levels in 12 hurricanes…
Arctic Amplification and Extreme Weather
The “Arctic Paradox” was coined during recent winters when speculations arose that the dramatic changes in the Arctic may be linked to severe snowstorms and cold temperatures in mid-latitudes, particularly along the U.S. east coast and in Europe. Recent studies have illuminated these linkages. Evidence is presented for a physical mechanism connecting Arctic Amplification —…
