Michael Mann, renowned climate scientist, says global warming can be stopped - as long as climate advocates can avoid succumbing to despair.

Nat Keohane, a climate expert, spoke with HKS faculty member Henry Lee at a Harvard Climate Action Week event held at the Kennedy School on the challenges and opportunities for building on recent progress in U.S. climate policy.

In January, two dozen Indigenous youth from across the circumpolar North visited Cambridge for the International Workshop on Indigenous Youth Leadership for the Changing Arctic. They joined Harvard Kennedy School students for the second half of IGA-67M: “Policy and Social Innovation for the Changing Arctic” for an intensive course in developing their own policy and social innovations to address issues in a region warming four times faster than the rest of the world.

Renowned climate scientist and author Dr. Katharine Hayhoe is a leader in efforts to change the public climate crisis conversation by focusing on solutions that provide hope rather than despair.  In a recent talk sponsored by the Belfer Center's Environment and Natural Resources Program, she shared her wisdom about how to overcome the psychological, societal, political and economic barriers that contribute to climate denialism and take positive actions based on shared values and concerns. 

What if we could repurpose oil and gas pipelines to supply remote Arctic communities with clean water? What if Arctic entrepreneurs could connect with investors and raise capital over an online crowdfunding platform? These were some of the novel solutions to Arctic challenges proposed by Harvard Kennedy School students during this year’s Arctic Innovation Lab in January.

A new study from the University of Leeds mostly confirmed previous estimates with greater precision, but it also found more variability than is currently accounted for in global climate models, writes Cristine Russell.

On the 45th anniversary of the classic blockbuster Jaws, Cristine Russell reflects on the film's troubling portrayal of white shark behavior, the current state of shark research, and the realities of human-white shark interactions today.

Cristine Russell details how the seasonal scientific field work in the Arctic — from the Toolik Field Station on Alaska's North Slope to ice core drilling in Greenland — is being postponed or cancelled this year because of the deadly COVID-19 pandemic.

The authors write that solving the challenges of a changing Arctic will require new approaches.
