İstanbul, gelişmekte olan ülkelerde bulunan ve deprem tehdidine açık olan birçok şehirden birisi. Bu şehirlerin nüfusu, barınacak güvenli konut sayısından çok daha hızlı artıyor.

Two groups of specialists on climate, energy, and technology policy have weighed in with hefty to-do lists for President-elect Barack Obama.

Since that era, when rain forest destruction achieved something close to the visibility of global warming today, the World Bank and its sister institutions, including the International Finance Corporation, have been talking the sustainability talk.

I have a story coming tonight in print on a new paper tracking the impact over time of those iconic drainpipes for meltwater forming each summer on the warming flanks of the vast Greenland ice sheet.

Twenty years ago today, James E.

New York City Mayor Michael R. Bloomberg discussed the disconnect between science and society in the opening address on Wednesday morning at a novel event, the inaugural World Science Festival.

The American Geophysical Union, the world's largest organization representing earth and space scientists, put out a fresh statement on the causes and consequences of recent climate change and possible responses.

Many Arctic plant species have readily adjusted to big climate changes, repeatedly re-colonizing the rugged islands of Norway's remote Svalbard archipelago through 20,000 years of warm and cool spells since the frigid peak of the last ice age, researchers say.

The latest United Nations assessment of the role of humans in global warming has found with "high confidence" that greenhouse gas emissions are at least partly responsible for a host of changes already under way, including longer growing seasons and shrinking glaciers. By Andrew C. Revkin

Internal memorandums circulated in the Alaskan division of the Federal Fish and Wildlife Service appear to require government biologists or other employees traveling in countries around the Arctic not to discuss climate change, polar bears or sea ice if they are not designated to do so.

The Bush administration estimates that emissions by the United States of gases that contribute to global warming will grow nearly as fast through the next decade as they did the previous decade, according to a long-delayed report being completed for the United Nations. By Andrew C. Revkin

If thought of as a painting, the scientific picture of a growing and potentially calamitous human influence on the climate has moved from being abstract a century ago to impressionistic 30 years ago to pointillist today. By Andrew C. Revkin

New studies project that the Arctic Ocean could be mostly open water in summer by 2040 — several decades earlier than previously expected — partly as a result of global warming caused by emissions of greenhouse gases. By Andrew C. Revkin

Rising ocean temperatures linked by some studies to tropical storms are very likely a result of global warming caused by greenhouse gas emissions, according to new research. By Andrew C. Revkin

Greenland's vast ice cap, which has had expanding melting zones in recent summers, is losing far more water to the sea than it is gaining through snowfall, and is thus contributing to rising sea levels, a research team said. By Andrew C. Revkin

A controversial paper asserting that recent warming in the Northern Hemisphere was probably unrivaled for 1,000 years was endorsed today, with a few reservations, by a panel convened by the nation's pre-eminent scientific body. By Andrew C. Revkin

The top climate scientist at NASA says the Bush administration has tried to stop him from speaking out since he gave a lecture last month calling for prompt reductions in emissions of greenhouse gases linked to global warming. By Andrew C. Revkin

In December 1997, representatives of most of the world's nations met in Kyoto, Japan, to negotiate a binding agreement to cut emissions of "greenhouse" gases. By Andrew C. Revkin

"They've got three more years, and the only way to control this issue and do nothing about it is to muddy the science." By Andrew C. Revkin

Under the first treaty addressing global warming, 193 countries, including the United States, pledged to avoid "dangerous" human interference with the climate. By Andrew C. Revkin

A top NASA climate expert who twice briefed Vice President Dick Cheney on global warming plans to criticize the administration's approach to the issue in a lecture at the University of Iowa tonight and say that a senior administration official told him last year not to discuss dangerous consequences

Harry Bader slogged across a patch of America's only Arctic shore, leaning into a late December gale that filled the midday twilight with blowing snow and sent the wind chill to 40 below.
