Following on from the comments by MITs Carl Wunsch that the Gulf Stream is safe as long as the wind blows and the Earth turns, several other scientists have used the pages of Science magazine (Apr. 16) to pour scorn on the conceit behind the forthcoming movie, The Day After Tomorrow. The movie is predicated on the idea that unchecked global warming will cause an abrupt climate shift that will cause a new ice age in the United States.
Canadian scientists Andrew…
The George C. Marshall Institute will host two briefings by Dr. David Legates, director of the University of Delawares Center for Climatic Research, speaking on “Global Warming and the Hydrologic Cycle: How is the Occurrence of Floods, Droughts, and Storms Likely to Change?” The first is at noon on Monday, April 12, in Room 406 of the Senate Dirksen Office Building. The second begins at noon on Wednesday, April 14, in Room 2325 of the Rayburn House Office Building. Lunch is…
Energy Bill Prompts Rash of Proposals
The Senate energy bill, S. 14, when published in draft form contained a climate change title. Three specific provisions raised alarm bells for many the requirement for a national strategy to “stabilize and over time reduce net U.S. emissions of greenhouse gases,” including annual reports; a revival of the Clinton-Gore Administrations White House climate czar and office; and a program to award credits for early action in reducing emissions.
Following protests against the title, such as…
Many children have been taught to fear the supposedly imminent arrival of global warming even though no one really knows if the world is getting hotter. While it is important to make children aware that current scientific evidence is inconclusive, it also may be helpful to put to rest some of the irrational fears of global warming. Facts, Not Fear, a guide book on teaching children about the environment by Jane Shaw and Michael Sanera, offers several suggestions.
First, they…
Please note that this glossary was compiled with defininitions from the United States Environmental Protection Agency.
Absorption of Radiation. The uptake of radiation by a solid body, liquid or gas. The absorbed energy may be transferred or re-emitted.
Acid Rain. Also known as “acid deposition.” Acidic aerosols in the atmosphere are removed from the atmosphere by wet deposition (rain, snow, fog) or dry deposition (particles sticking to vegetation). Acidic aerosols are present in the atmosphere primarily due to discharges of gaseous sulfur oxides (sulfur dioxide) and nitrogen…
The paper published by Frank Wentz and Matthias Schabel in Nature this week (August 14, 1998) is bound to generate controversy about the satellite measurements of global tropospheric temperatures. These measurements, for the period since 1979, have been made with the TIROS-N satellite Microwave Sounding Units (MSUs) by myself and Dr. John Christy (The University of Alabama in Huntsville). We are grateful to Wentz and Schabel for discovering the first convincing evidence for needed corrections to our satellite-based global temperatures.…

Executive Summary
Understanding the causes for changes in the weather day to day and year to year can be difficult because the complex systems underlying weather and climate change are not completely understood.
Recent articles in the press have reported that our weather is becoming more and more extreme and more destructive. Hurricane Andrew, devastating floods in California and the Midwest and the brutal winter storms that struck the Northeast last year are cited as the…
