Climate change is happening today. Scientists have known for some time, from multiple lines of evidence, that humans are changing Earth’s climate, primarily through greenhouse gas emissions.
The evidence is clear and compelling. Earth’s atmosphere and oceans are warming, the magnitude and frequency of extreme climate and weather events are increasing, and sea level is rising along our coasts.
Climate change is increasingly affecting people’s lives. It is having significant effects on infrastructure, agriculture, fisheries, public health, and the ecosystems that support society. It is also changing the environment in ways that affect the distribution, diversity, and long-term survival of species of plants, animals, and other forms of life on Earth.
Decision makers are taking climate into consideration in a variety of contexts—such as federal energy policies and standards, state infrastructure investments, community adaptation plans, which crops to plant, public health strategies, approaches to ecosystem management, sustainable business practices and procedures, national security policy and infrastructure, and personal financial investments and education.
The National Academies are actively working to advance understanding of climate science and its intersection with many areas of science, engineering, and medicine. We are providing guidance on options for limiting the magnitude of climate change and adapting to its impacts. We are also making it easier to use our extensive body of work, increasing its accessibility to decision makers and the public to inform their decisions.
This website is intended to mark the beginning of those efforts. Click on the Discover tab to find useful summaries and links to National Academies resources outlining our understanding of the climate system, of current and anticipated climatic changes, of ways to adapt to these changes, and of potential options to mitigate or lessen future climate change and its impacts on society.
