A new analysis finds that if global warming reaches 2 degrees Celsius, it could trigger a feedback, or "tipping element," in one or more of our natural systems and drive further warming. Diana Liverman, a UA Regents' Professor of geography and development, is a coauthor on the article.
The UA is an international leader in climate science, impacts and policy. We use paleoenvironmental techniques to reconstruct past climates and computer models to understand future conditions. We look at how patterns of drought and heatwaves change and cause water shortages, increase wildfire risks, reduce crop production and food security, threaten defense installations, and affect human health and ecosystems. We work with partners to deliver usable climate science and to create effective responses that help people focus on adaptation, resilience, and risk reduction in the face of climate change.
