The University of Arizona is recognized nationally and internationally as a leader in the science of adaptation to climate change, and associated research and outreach to understand climate change, its observed and potential impacts, and possible responses.
Front Page Summary
The Earth’s climate is changing, and the impacts of climate change are being observed across the United States and in other nations.
Since the late-1800s, we’ve experienced global warming of about 1.5 degrees F. During the last several decades, the Southwest has warmed more than the rest of the contiguous United States. Scientists conclude that much of the warming is very likely due to human activities.
Even if human-caused greenhouse gas emissions were substantially reduced now, climate would continue to warm for some time to come and the potential consequences for humans and ecosystems are substantial.
Adaptation – taking actions to reduce vulnerabilities or increase resilience to climate changes – can help avoid or minimize disruptions, costs, and damages to society and the environment.
