Through a series of questions and answers, readers are introduced to the basic fundamentals of the carbon cycle and the importance of carbon as a greenhouse gas. This lesson is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

A question and answer format is used to differentiate between weather and climate, and to provide a brief overview of global warming. This lesson is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

The greenhouse effect is explained in this series of related questions and answers. This lesson is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

This article explains the role that the ocean- and the effect of ocean warming- plays in determining the temperature differences between the North and South Poles. The article is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

Arctic warming produces biological winners (whales) and losers (polar bears). This article explains why they are impacted differently and includes supplemental images. This lesson is part of the Climate Kids website, a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

This resource is a website that is a self-contained, multi-part introduction to how climate models work. The materials include videos and animations about understanding, constructing and applying climate models.

This video explains how scientists construct computer-generated climate models to forecast weather, understand climate, and project climate change. It discusses how different types of climate models can be used and how scientists use computers to build these models.

The Climate Momentum Simulation allows users to quickly compare the resulting sea level rise, temperature change, atmospheric CO2, and global CO2 emissions from six different policy options projected out to 2100.

This interactive visualization is a suite of weather and climate datasets as well as tools with which to manipulate and display them visually.

This is a rich compilation of resources and tools to help decision-makers across the US identify their local climate threats and vulnerabilities and reduce their risks from impacts of climate​ variability and change. As part of President Obama's Climate Action Plan, the toolkit was developed by NOAA in partnership with NASA and other departments and agencies in the U.S. Global Change Research Program.

This video is part of the Climate Science in a Nutshell video series. This short video looks at the effects of climate change happening right now around the globe, including: more extreme weather events, droughts, forest fires, land use changes, altered ranges of disease-carrying insects, and the loss of some agricultural products. It concludes with a discussion of the differences between weather, climate variability, and climate change.

This short video discusses where carbon dioxide, the gas that is mainly responsible for warming up our planet and changing the climate, comes from. It discusses how the rise in atmospheric carbon dioxide comes directly from the burning of fossil fuels and indirectly from the human need for energy.

This is a simulation that illustrates how temperature will be affected by global CO2 emission trajectories. It addresses the issue that even if global emissions begin to decrease, the atmospheric concentration of CO2 will continue to increase, resulting in increased global temperatures.

This video provides background information and teaching tips about the history and relevance of phenology and seasonal observations of plants and animals within the context of rural Wisconsin.

This is an interactive webtool that allows the user to choose a state or country and both assess how climate has changed over time and project what future changes are predicted to occur in a given area.

In this video segment adapted from NOVA: Becoming Human, learn how the analysis of rock layers and ocean sediments supports the theory that rapid climate change may have jump-started human evolution two million years ago.

In this activity, students explore connections between climate change and the cryosphere. In Part A, they learn about how scientists study past climate records using ice cores. In Part B, students examine the role ice melt might play in future sea level rise due to climate change.

This static graph of changes in CO2 concentrations goes back 400,000 years, showing the dramatic spike in recent years.

In addition to instructions for making a model bee out of polymer clay, this site also contains related information about bees: a fact list, factors that threaten them, suggestions on how to help them, a waggle dance diagram and video, and even bee metaphors used in our language. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

The purpose of this resource is to have students observe their lilac plants and identify the five phenophases (first leaf, full or 95% leafed, first bloom, full bloom and end of bloom) for each lilac plant. During the growing season, students will observe their lilac plants and identify the five phenophases (first leaf, full or 95% leafed, first bloom, full bloom and end of bloom) for each lilac plant.
