Rapid Climate Change in the Arctic: Why Everybody Should Care

| June 06, 2019

Note

Professor John P. Holdren gave this lecture, hosted by Dean of Schwartzman Scholars Xue Lan, at Tsinghua University in Beijing on June 6, 2019.

Summary

Temperatures are increasing in the Arctic 2 to 4 times faster than the global average rate of warming.  Sea ice and snow cover are shrinking; glaciers and the great Greenland ice sheet are likewise shrinking, thus contributing to sea-level rise; permafrost is thawing; wildfires are becoming larger and more frequent; and the Arctic Ocean is becoming less saline and more acidic.

The reduction of sea-ice cover is opening up new opportunities for navigation, fishing, and resource development, but with these opportunities come new requirements for monitoring, governance, and regulation.  Still more challenging are the impacts of all of the changes on Arctic communities, infrastructure, and wildlife, as well as on the pace of climate change and sea-level rise worldwide.

In this lecture, Dr. John P. Holdren first summarized the latest science relating to climate change in the Arctic and its impacts in the region and worldwide.  Then, he discussed the efforts that are underway to improve our detailed understanding of what is happening and to address the array of challenges that result.  He concluded by discussing what further actions from the global community are required.
