Illinois professor to address global warming at book launching

Michael Schlesinger, a professor of atmospheric sciences at the University of Illinois at Urbana-Champaign, will participate in news conferences in New York City on May 9, and Washington, D.C., on May 10, publicizing the U.S. debut of the book “Avoiding Dangerous Climate Change.”

Published by Cambridge University Press, the book builds upon scientific findings presented at the “Avoiding Dangerous Climate Change” conference held in Exeter, England, in February last year. The conf

A new math model finds that the cochlea’s spiral shape enhances low frequencies

The next time someone whispers in your ear, think “cochlea.”

The cochlea is the marvelous structure in the inner ear that is shaped like a snail shell and transforms sounds into the nerve impulses that your brain can process and interpret. You may remember learning about it in elementary school anatomy.

This critical hearing organ consists of a fluid-filled tube about a cubic centimeter (three hundredths of an ounce) in volume. For decades, hearing experts thought that

It’s a Bug’s Life beneath Bermuda Triangle

Census of Marine Life scientists trawled rarely explored tropical ocean depths between the southeast US coast and the Mid-Atlantic Ridge to inventory and photograph the variety and abundance of zooplankton – small sea “bugs” that form a vital link in the ocean food chain – and other life forms.

Though relatively few in number compared with the uppermost ocean layer, scientists were amazed by the variety of tiny animals found at depths of 1 to 5 km (0.6 to 3 miles). Among thou

La Nina Will Have No Effect on 2006 Atlantic Hurricanes

NASA oceanographers agree that the recent La Nina in the eastern Pacific Ocean is not expected to have an effect on the Atlantic hurricane season this year. That is good news, because normally a La Niña tends to increase Atlantic hurricane activity and decrease Pacific Ocean hurricanes.

Although La Nina occurs in the Pacific, it affects weather in the Atlantic Ocean as well, through changes in the winds. La Niña changes the wind patterns in the upper and lower levels of the atmosp

Man-Made Climate Change

New study identifies human contribution to atmosphere circulation changes

A new study published in this week’s issue of Nature is the first to show that human activity is altering the circulation of the tropical atmosphere and ocean through global warming.

Scientists widely agree that the climate has warmed over the past century and that human activities, such as burning fossil fuels, have significantly contributed to this global warming. This study tapped hi

Slowdown in tropical Pacific flow pinned on climate change

The vast loop of winds that drives climate and ocean behavior across the tropical Pacific has weakened by 3.5% since the mid-1800s, and it may weaken another 10% by 2100, according to a study led by University Corporation for Atmospheric Research (UCAR) scientist Gabriel Vecchi. The study indicates that the only plausible explanation for the slowdown is human-induced climate change. The findings appear in the May 4 issue of Nature.

The Walker circulation, which spans almost half the cir
