The Global Warming Archive Skeptic Asks, Is It Really Warmer? (June 17, 1996) By WILLIAM K. STEVENS As climate experts firm up their view that human activity is seriously altering the atmosphere, one voice stands out in clarion dissent. It is that of Dr. Richard S. Lindzen of the Massachusetts Institute of Technology, a shoemaker's son from the Bronx who has risen through the academic hierarchy as a leading expert on the physical processes of the atmosphere.     Global Warming HOME ARCHIVE FORUMS GLOSSARY RESOURCES Believer Finds Himself at Center of Hot Debate (August 5, 1996) By WILLIAM K. STEVENS Dr. Benjamin D. Santer, a shy, even-spoken, 41-year-old American climatologist who climbs mountains, runs marathons and enjoys a reputation for careful and scrupulous work, is the chief author of what may be the most important finding of the decade in atmospheric science: that human activity is probably causing some measure of global climate change, as environmentalists have long assumed and skeptics have long denied.  World Awaits U.S., Japan in Climate Talks (August 12) By WILLIAM K. STEVENS As time grows short in the latest and most serious attempt to deal with the prospect of global warming, everyone is waiting for two decisive players -- the United States and Japan -- to get their acts together.  Experts on Climate Change Ponder: How Urgent Is It? (September 9) By WILLIAM K. STEVENS With the nations of the world counting down to a Dec. 10 deadline for negotiating cuts in emissions of heat-trapping greenhouse gases that many scientists say are altering the earth's climate, a fundamental question continues to pervade the debate:  Just how urgent is the problem of climate change?  If Climate Changes, Who Is Vulnerable? Panels Offer Projections (September 30) By WILLIAM K. STEVENS If mainstream scientists are right in their forecast that the earth will warm up substantially in the decades ahead, what will happen to a place like, say, New England? Will its brilliant fall foliage fade? Its sugar maples migrate to Canada? Its ski slopes turn to slush? Its tourists vanish?  Climate Change Is Hot Topic at the White House (October 2) By JAMES BENNET It was cloudy and cool outside the north portico of the White House on Wednesday morning as Steve Doocy, the jovial Fox News Channel weatherman, asked Al Roker, the ebullient NBC weatherman, just why it was that the president of the United States had invited them over.     Cost Uncertainties Delaying Action on Global Warming Policy (October 6) By WILLIAM K. STEVENS With President Clinton having accepted the dominant view among scientists that global warming is a serious matter, the increasingly urgent debate over what to do about it has largely shifted to the question of how restricting emissions of heat-trapping greenhouse gases like carbon dioxide may affect the nation's economy.  Output of Gases Is Rising (October 19) By JOHN H. CUSHMAN Jr. The United States said today that its emissions of heat-trapping gases grew last year at the highest rate since the nation pledged to cut them back.     Computers Model World's Climate, but How Well? (November 4) By WILLIAM K. STEVENS Tom's Restaurant at 112th Street and Broadway in Upper Manhattan is right out of "Seinfeld." But six floors above, Dr. Makiko Sato and Dr. James E. Hansen are conjuring up a bigger world from the innards of what looks like a slightly oversized personal computer. This is no ordinary computer, however. It contains the earth's atmosphere and oceans, albeit in mathematical form, interconnected to create a virtual global climate system.  From Under the Sea, Signs of Climate Jolts (November 18) By WILLIAM K. STEVENS As scientists seek to improve their imperfect understanding of how and why the world's climate is changing, evidence continues to mount that most of the last 10,000 years -- long thought to be a benign era whose stability was crucial to the rise of civilization -- has in fact been typified by episodes of warmth, cold, drought, and flooding more extreme than anything experienced in the 20th century.
