Human warming hobbles ancient climate cycle

WASHINGTON (Reuters) - Before humans began burning fossil fuels, there was an eons-long balance between carbon dioxide emissions and Earth's ability to absorb them, but now the planet can't keep up, scientists said on Sunday. The finding, reported in the journal Nature Geoscience, relies on ancient Antarctic ice bubbles that contain air samples going back 610,000 years.

Plan to reverse global warming could backfire

CHICAGO (Reuters) - A proposed solution to reverse the effects of global warming by spraying sulfate particles into Earth's stratosphere could make matters much worse, climate researchers said on Thursday. They said trying to cool off the planet by creating a kind of artificial sun block would delay the recovery of the Antarctic ozone hole by 30 to 70 years and create a new loss of Earth's protective ozone layer over the Arctic.

Timeline for Irreversible Climate Change

Fifty years ago, Yankee Stadium had about 70,000 seats. It seldom sold out, and almost any kid could afford the cheapest seats. Capacity was reduced to about 57,000 when the stadium was remodeled in the 1970s. Most games sell out now, and prices have gone up. The new stadium, opening next year, will reduce seating to about 51,800.

Security risk from climate said underestimated

LONDON (Reuters) - Countries around the world have hugely underestimated the potential conflicts stemming from climate change and must invest heavily to correct that mistake, a report said on Wednesday. The report for Britain's Royal United Services Institute (RUSI) by environment expert Nick Mabey said the response had been "slow and inadequate" and to rectify it spending needed to surge to levels comparable to sums spent on counter-terrorism.

Report confirms ozone pollution can kill

WASHINGTON (Reuters) - Even breathing in a little ozone at levels found in many areas is likely to kill some people prematurely, the National Research Council reported on Tuesday. The report recommends that the Environmental Protection Agency consider ozone-related mortality in any future ozone standards, and said local health authorities should keep this in mind when advising people to stay indoors on polluted days.

As Earth Day Arrives, Population Still the Uneasy Issue
April 22, 2008 09:20 AM - , Worldwatch Institute

NEW ORLEANS-People walking around the Sheraton Hotel here are talking about population as if it were the most natural conversation in the world. The topic interests me, so I join in. As it happens, I've written a book on it, just published by Island Press, which I don't shrink from mentioning. Just being here, though, reminds me that human numbers aren't often talked about outside this hotel.

Freshening of deep Antarctic waters worries experts

SINGAPORE (Reuters) - Scientists studying the icy depths of the sea around Antarctica have detected changes in salinity that could have profound effects on the world's climate and ocean currents. The scientists returned to the southern Australian city of Hobart on Thursday after a one-month voyage studying the Southern Ocean to see how it is changing and what those changes might mean for global climate patterns.

Turtles to be climate change canaries

Just as canaries help miners monitor underground gases, marine turtles are emerging as excellent indicators of the effects of climate change. “Turtles are a really good way to study climate change because they depend on healthy beaches as well as mangroves, sea grass beds, coral reefs and deep ocean ecosystems to live”, said Dr. Lucy Hawkes, coordinator of an initiative to develop adaptation strategies for climate change impacts to turtles.

Bush climate plan criticized for lacking urgency
April 17, 2008 08:38 AM - Reuters

PARIS (Reuters) - The world needs tougher action to combat global warming than a plan by President George W. Bush to halt a rise in U.S. greenhouse gas emissions only by 2025, delegates at a climate conference in Paris said on Thursday. South Africa, one of 17 nations at the two-day global warming talks that started on Thursday, called Bush's proposals "disappointing" and unambitious when many other industrialized economies are already cutting emissions.

GOING, GOING, GONE? New Satellite Images Reveal a Shrinking Amazon Rainforest

Washington, D.C.- Deforestation of the Brazilian Amazon may be on the rise, according to high-resolution images released by an agency of the Brazilian government. The images suggest an end to a widely hailed three-year decline in the rate of deforestation and have spurred a public controversy among high-level Brazilian officials, writes Tim Hirsch, author of "The Incredible Shrinking Amazon Rainforest" in the May/June 2008 issue of World Watch magazine.
