The report, compiled by National Oceanic and Atmospheric Administration’s Center for Weather and Climate, shares detailed updates on annual changes to global climate indicators and weather events. This year’s report details 2017 climate records, which include Earth experiencing record-high sea level rises and significant losses of Arctic sea ice. According to the report, Arctic air temperatures increased at twice the rate of the rest of the world. The report called the magnitude and sustained rate of declining sea ice unprecedented. Stephanie Pfirman, a professor at Arizona State University's School of Sustainability, studies climate change, with emphasis on changes in Earth’s polar regions — along with diversity in interdisciplinary research. Pfirman spoke to ASU Now about what’s next for Earth’s Arctic sea ice.
