The NOAA Sea Level Trends map illustrates U.S. regional and some international trends in sea level, with arrows representing the direction and magnitude of change. Students can investigate sea level changes around the U.S. and some worldwide using an interactive map interface with supporting data plots and tables.

A short video on the satellite ICESat-2 and what it measures (ice).

This short video, adapted from NOVA, explains how Earth's position relative to the Sun might be responsible for the dramatic shift in the climate of what is now the Saharan nation of Djibouti.

This easy-to-understand video animation describes drought and explains the different categories of drought used by the drought monitor. It discusses the effects of and contributions to drought, what the implications of the different drought levels are, and puts the drought maps into context to understand how the impacts vary geographically (e.g. drought in Nevada vs Kansas - one could affect tourism, the other agriculture). It also touches on how the development of maps/drought severity is determined and how it might vary geographically. The animation provides a basic overview of statistics and percentiles and the concept of '100 year events.'

This video considers the current estimates of sea level rise as possibly too conservative and discusses more recent data on ice melt rates coming from Antarctica and Greenland, showing rates of melt at up to 5 times as rapid. Scientists discuss what levels and rates of sea level rise have occurred in the past, including the Pliocene, which demonstrated 1m rise every 20 years.

This short video, is the fifth in the National Academies Climate Change, Lines of Evidence series. It focuses on greenhouse gases, climate forcing (natural and human-caused), and global energy balance.

This animation shows the Arctic sea ice September (minimum) extents from 1979-2016. Accessible from

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

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

This video describes the joint NASA-JAXA GPM (Global Precipitation Measurement) satellite mission and why it is necessary for monitoring precipitation around the Earth. It also discusses the science around issues of having too much or too little precipitation such as landslides and drought. It emphasizes the need for data to fill in gaps, and why data and being able to predict natural disasters is so valuable.
