The Arctic Needs Better Cross-sector Crisis-related Collaboration

| Aug. 06, 2020

Arctic Innovator Jenna Stark recommends closing the crisis-related collaboration gap in the polar region. Greater communication between emergency response specialists is needed both for the Arctic to weather the current coronavirus crisis and also to prepare for and mitigate future disasters, such as assuring food security for remote communities in the event of a wildlife disease outbreak.

How to Globalize Clean Energy

| June 20, 2020

The authors argue that more determined efforts to globalize renewable energy transmission can confer significantly higher economic and environmental benefits from renewables on billions of people. This can be done by exploiting spatial differences between electricity loads and net renewable generation across time zones (temporal arbitrage) and latitude (seasonal arbitrage). Using very long distance, ultra-high voltage (UHV) transmission infrastructure, temporal and spatial arbitrage can move low-cost clean electricity from areas with excess capacity to high demand zones in other countries and even continents.

Thawing Arctic Permafrost: Regional and Global Impacts

| May 11, 2020

Temperatures across the Arctic are increasing two to four times faster than the global average. The dramatic consequences that are already apparent include reduction of sea-ice cover, accelerating loss of land ice from glaciers and the Greenland Ice Sheet, proliferating wildfires, and—the topic of this panel—ongoing heating and thawing of the permafrost that underlies most of the land area of the Arctic and sub-Arctic regions across the globe
