f. Natural processes driving Earth's long-term climate variability do not explain the rapid climate change observed in recent decades. The only explanation that is consistent with all available evidence is that human impacts are playing an increasing role in climate change. Future changes in climate may be rapid compared to historical changes.

This graphic indicator describes trends in average surface temperature for the United States and the world.

This infographic provides an overview of what coral bleaching is and its causes. The resource combines short summaries of the steps of coral bleaching with more in-depth (though still succinct) explanations for what is happening to cause the coral to appear white. A short list of causes for coral bleaching is also provided.

This video provides a good introduction to the field of attribution science. Beginning with an introduction to weather and climate, it describes how severe weather might be linked to climate change and the science behind attribution studies. It gives a good explanation behind how scientists use climate models to study whether severe weather events were influenced by climate change.

This peer-reviewed educational video explains human-caused climate change including the greenhouse effect. The role that greenhouse gases play in absorbing and re-emitting longwave radiation is illustrated. Information on how scientists know that the observed global warming is a result of human activities that burn fossil fuels is concisely explained.

This collection of learning activities allows students to explore phenology, phenological changes over time, and how these changes fit into the larger context of climate change. Students explore patterns of solar radiation and seasons as well as phenological cycles and ecological affects of these patterns.

This unit allows students to investigate past changes in Earth's climate. Students first explore relationships in climate data such as temperature, solar radiation, carbon dioxide, and biodiversity. They then investigate solar radiation in more depth to learn about changes over time such as seasonal shifts. Students then learn about mechanisms for exploring past changes in Earth's climate such as ice cores, tree rings, fossil records, etc.

This visualization provides an informative summary of the quarterly seasonal global weather and climate using the 3-D Science on a Sphere format. These video summaries use animations of recent NOAA data and an engaging commentary to review the climate highlights of the past 4 seasons. Topics include, El Nino/La Nina, temperature trends, extreme weather, and emerging climate research.

This learning activity is a climate change musical for K-12, youth groups or faith organizations. Shine weaves together climate science and performance art into a fun and powerful story, which spans 300 million years of geological time to convey how humanity, energy, and climate are interrelated.

This video succinctly explains the mechanism of the natural greenhouse effect and the cause of global climate change (anthropogenic global warming). It is short, basic, and to the point. It's also available in 12 languages!

This online quiz tests knowledge about climate change, its impacts, how we know about earth's climate, and potential solutions.
