The record-breaking heat that made 2016 the hottest year ever recorded has continued into 2017, pushing the world into "truly uncharted territory," according to the World Meteorological Organization. "Earth is a planet in upheaval due to human-caused changes in the atmosphere," said Jeffrey Kargel, a glaciologist at the UA. "In general, drastically changing conditions do not help civilization, which thrives on stability."
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.
