Ice-Covered Arctic Lakes May Harbor Signs of Climate Change

Arctic coastal environments are some of the most vulnerable to climate change. A team of WHOI researchers visited Canada’s Mackenzie River Delta in April 2007 to find out just how vulnerable.

Should We Pump Iron to Slow Climate Change?

One of the solutions offered for the global greenhouse gas problem is the fertilization of the ocean; that is, spreading iron into the open ocean to promote the growth of floating microscopic plants.

Climate Change in the Bottom of a Lake

Climate is often discussed in global terms, but it is the regional and local effects that will matter most to everyday people.

Rapid Sea Level Rise in the Arctic Ocean May Alter Views of Human Migration

Scientists have found new evidence that the Bering Strait near Alaska flooded into the Arctic Ocean about 11,000 years ago, about 1,000 years earlier than widely believed, closing off the land bridge thought to be the major route for human migration from Asia to the Americas.

Linking Climate Change Across Time Scales

Scientists have found links in global variations in temperature that may provide insight to the bigger picture of climate change.

Walrus Calves Stranded by Melting Sea Ice

Scientists have reported an unprecedented number of  abandoned walrus calves in the Arctic Ocean, where melting sea ice may be forcing mothers to abandon their pups.

Warmer than a Hot Tub: Atlantic Ocean Temperatures Much Higher in the Past

Scientists have found evidence that tropical Atlantic Ocean temperatures may have once reached 107°F, about 25°F higher than ocean temperatures today and warmer than a hot tub. While these high ocean temperatures occurred millions of year ago, the new study suggests climate models underestimate future warming.

Fine-tuning the Steps in the Intricate Climate Change Dance

New scientific findings are strengthening the case that rapid climate change may be related to how vigorously ocean currents move heat between low and high latitude.

New Coral Dating Technique Helps Resolve Changes in Sea Level Rise in the Past

Corals from Papua New Guinea and Barbados indicate that changes in sea level, one of the key indexes for global climate change, may have been more frequent in the past than previously thought.

Changes in Earth's Tilt Control When Glacial Cycles End

Scientists have long debated what causes glacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study finds that these glacial cycles are paced by variations in the tilt of Earth’s axis, and that glaciations end when Earth's tilt is large.

Abrupt Climate Change Brought to Public Attention in Hollywood Movie

The movie The Day After Tomorrow, released today by 20th Century Fox, paints a dramatic picture of the effects of climate change - and raises questions about the boundary between science and science fiction.

Tropical Plants Help Identify Lags Between Abrupt Climate and Vegetation Shifts in Different Parts of the World

Clues to the timing and cause of abrupt climate changes in the past may lie in ocean floor sediments, according to a study by scientists at Woods Hole Oceanographic Institution.
