Minimum sea ice extent observed by satellites each September has decreased by 13.7 percent per decade since the late 1970s. The seven lowest extents all occurred since 2007.

This video provides an overview of changes happening in the Arctic.

This is a series of 5 guided-inquiry activities that examine data and models that climate scientists use to attempt to answer the question of Earth's future climate.

In this worksheet-based activity, students review global visualizations of incoming sunlight and surface temperature and discuss seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres and how land and water absorb and release heat differently. The activity culminates in an argument about why one hemisphere experiences warmer summers although it receives less total solar energy.

This video, from Yale Climate Connections, explores the 2014 melting of the West Antarctic ice sheet that captured headlines. Interviews, animations, and news broadcasts explore what the melting meant for both the future of some of the Antarctic glaciers and sea level rise, and informs the viewer how seafloor terrain influences the speed of ice sheet melt.

An interactive simulation that allows the user to adjust mountain snowfall and temperature to see the glacier grow and shrink in response.

How can warming at Earth’s surface have slowed when energy accumulation is growing? The role of our oceans—including ENSO—is key.

This is the first of nine lessons in the Visualizing and Understanding the Science of Climate Change website. This lesson is an introduction to Earth's climate and covers key principles regarding Earth's unique climate, atmosphere, and regional and temporal climate differences.
