Global Climate Change
This site lets you explore scientific data relating to the atmosphere, the oceans, the areas covered by ice and snow, and the living organisms in all these domains. Learn more about the ways scientists study these natural phenomena — and how they interact with climate change.

Weather and Climate Basics
What's the difference between weather and climate? How are they related? Find out on this National Center for Atmospheric Research site.

Climate Timeline
Investigate the last 100,000 years of climate. Learn about the different forces that have shaped it — and the techniques scientists use to find out what happened.

Abrupt Climate Change
This WHOI page has a number of articles about abrupt climate change and the ocean's possible role, some written by the scientists featured in "Hot Planet — Cold Comfort." Also read a scientific assessment of Hollywood's "The Day After Tomorrow."

Climate of Uncertainty
Check out the website for this radio documentary that focuses on climate change. Topics include the information locked in ice cores, what's happening with the ocean conveyor, and whether anything can be done to affect the way the climate's headed.

The Gulf Stream
Learn more about the 'sea's greatest river' and see a map that diagrams its flow past North America.

Density of Ocean Water
Simple physics explains why saltwater has a particular density. Learn more about the factors that influence density.

Catastrophic Flooding From Ancient Lake May Have Triggered Cold Period
New WHOI research suggests that 13,400 years ago, a huge glacial lake burst through its dam and added huge amounts of fresh water to the North Atlantic. Scientists say this event could have triggered a cooling period in the climate.

Study Reveals Increased River Discharge to Arctic Ocean
Dig into the specifics of research MBL scientists have done examining the increased levels of freshwater that are flowing from Russian rivers into the Arctic Ocean.

Snow, Ice and Permafrost Group
This is the University of Alaska Fairbanks home to Keith Echelmeyer, By Valentine and Anthony Arendt, the scientists carrying out the airborne laser altimetry measurements of glaciers. Check out more about these projects and others their colleagues are working on.

Laser Altimetry
Learn more about the technique scientists use to measure exact heights using laser altimeters and GPS.

Ultima Thule Lodge
This remote lodge in the Wrangell Mountains is the base camp for the flights that use laser altimetry to measure glaciers.

The Little Ice Age
This article discusses the LIA and glacier movement throughout the world during this time, as well as possible factors that led to the LIA.

The Little Ice Age in Europe
This article explores how colder temperatures affected agriculture, human health, the economy and social stability during the Little Ice Age.

Coring the Ocean Floor
Tag along on a research cruise and see how scientists obtain their deep sea sediment cores.

Ground-Truthing the Paleoclimate Record
This WHOI page explains how the fossil record helps scientists piece together what the ancient climate was like.

Ice Cores Unlock Climate Secrets
Read a BBC article about a 3km long ice core that reveals climate data going back 740,000 years.

Station W
Learn more about the moored buoys WHOI scientists use to collect data on the Gulf Stream.

The Nature Conservancy
News and information about The Nature Conservancy's Global Climate Change Initiative.
