Animation showing the monthly variation of sea ice extent in the Arctic from 2016 through 2018.

This video describes how climate scientists use "proxy data", such as the information stored in coral, to study climates of the past.

There is much more variation in the path that the dog takes as compared with the man, but they are both headed the same way. Similarly, weather can be highly variable and climate means long term trends.

Professor Scott Denning of Colorado State University explains how greenhouse gases in Earth's atmosphere warm our planet.

This video describes how climate scientists use "proxy data", such as the information stored in ice cores, to study climates of the past.

This video describes how climate scientists use "proxy data", such as the information stored in layers of sediments from the bottoms of lakes, to study climates of the past.

This animation shows warming of the Earth's surface according to the results of climate model (called the NCAR Community Climate System Model) from 1870-2100.

This video describes how small changes in emissions can cause significant changes in the amount of carbon dioxide in the atmosphere.

This movie explains how climate scientists use "fuzzy" proxy records to learn about climates of the past.

This video explains how climate records from the past show that changes in temperature and changes in atmospheric carbon dioxide go hand-in-hand.

This video explains how COSMIC satellites monitor our atmosphere, collecting data that is used to improve weather forecasts, monitor the upper atmosphere, and understand our climate.

This movie explains how scientists study past climates to help make better predictions about future climate change.

You may know that melting glaciers and ice sheets is causing sea levels to rise. Did you also know that the ocean absorbs heat, causing it to expand? Learn more about this process and how it’s impacting coastlines around the planet.
