This is an interactive graph that involves records of ice cover in two Wisconsin lakes - Lake Mendota and Lake Monona - from 1855-2010.

In this activity, students learn about sea ice extent in both polar regions (Arctic and Antarctic). They start out by forming a hypothesis on the variability of sea ice, testing the hypothesis by graphing real data from a recent 3-year period to learn about seasonal variations and over a 25-year period to learn about longer-term trends, and finish with a discussion of their results and predictions.

In this activity students use NASA satellite data to study changes in temperature and snow-ice coverage in the South Beaufort Sea, Alaska. They will then correlate the data with USGS ground tracking of polar bears and relate their findings to global change, sea ice changes, and polar bear migration and survival.

This video examines the thawing of permafrost due to changes in climate and shows examples of the impacts that warming temperatures have on permafrost in the Arctic, including the release of the greenhouse gas methane. Dramatic results are shown, including sink holes forming on the landscape and beneath buildings, roads, and other infrastructure, causing some communities to relocate.

This NBC Learn video features climate scientists doing their research on Mt. Kilimanjaro to study the climate of the past. The scientists put the recently observed changes on the glacier into perspective by comparing past climate fluctuations, stressing that the current observed rate of change is unprecedented.

This video, along with a background essay, focuses on impacts of climate change on the lives of Native Alaskans around Barrow, Alaska. Specific changes include the timing of the changes in the formation and breakout of sea ice and the impacts on subsistence living.

2012 Arctic Report Card

The annual Report Card provides clear, concise scientific information on the state of the Arctic region, organized into 5 sections: Atmosphere, Sea Ice & Ocean, Marine Ecosystems, Terrestrial Ecosystems, and Hydrology & Terrestrial Cryosphere. This edition was prepared by an international team of 121 scientists from 14 different countries. Independent peer-review of the 2012 Report Card was organized by the Arctic Monitoring and Assessment Programme of the Arctic Council.

Shoreline Management Toolbox

A suite of tools that provides guidance on addressing issues such as coastal erosion and sea level rise.

State of the Climate in 2010

Over 360 authors from 45 countries contributed to this comprehensive appraisal of the Earth’s climate. Observations from pole-to-pole show climate patterns such as La Niña and El Niño contributed to some climate events this year. Trends consistent with manmade climate change over the last 50 years are also continuing. These include warming temperatures, melting glaciers and saltier seas, which are related to rising atmospheric greenhouse gas concentrations.
