Scientists Detail Climate Changes, Poles to Tropics

Martin Parry, the co-chairman of a scientific panel on climate change, presented a new report on global warming Friday in Brussels.

BRUSSELS, April 6 — From the poles to the tropics, the earth’s climate and ecosystems are already being shaped by the atmospheric buildup of greenhouse gases and face inevitable, possibly profound, alteration, the world’s leading scientific panel on climate change said Friday.

And it said that while limits on smokestack and tailpipe emissions could lower the long-term risks, vulnerable regions must adjust promptly to shifting weather patterns, climatic and coastal hazards, and rising seas.

Without such adaptations, it said, a rise of 3 to 5 degrees Fahrenheit over the next century could lead to the inundation of coasts and islands inhabited by hundreds of millions of people. But if steady investments are made in seawalls and other coastal protections, vulnerability could be sharply reduced.

The group, the United Nations’ Intergovernmental Panel on Climate Change, also noted that the climate shifts would benefit some regions — leading to more rainfall and longer growing seasons in high latitudes, open Arctic seaways and fewer deaths from the cold.

Climate report: Poor will suffer most

By ARTHUR MAX, Associated Press Writer

BRUSSELS, Belgium - The world faces increased hunger and water shortages in the poorest countries, massive floods and avalanches in Asia, and species extinction unless nations adapt to climate change and halt its progress, according to a report approved Friday by an international conference on global warming.

Agreement came after an all-night session during which key sections were deleted from the draft and scientists angrily confronted government negotiators who they feared were watering down their findings.

<...>

Several scientists objected to the editing of the final draft by government negotiators but, in the end, agreed to compromises. However, some scientists vowed never to take part in the process again.

There was little doubt about the science, which was based on 29,000 sets of data, much of it collected in the last five years. "For the first time we are not just arm-waving with models," Martin Perry, who conducted the grueling negotiations, told reporters.

The United States, China and Saudi Arabia raised many of the objections to the phrasing, often seeking to tone down the certainty of some of the more dire projections.
