We hear a lot about polar bears and other Arctic mammals in connection to climate change, but what about biodiversity in Antarctica?

News from the Columbia Climate Center on the science and impacts of climate change on society as well as environmental public policy analysis.
The presidential election of 2016 will determine the United States’ role in confronting the global challenge of climate change, and preparing our nation to manage its impacts for years to come. Where do the presidential candidates stand today on these issues?
We are losing coral reefs at an alarming rate and scientists believe that with business as usual they will likely be gone by the end of the century. However, better local management, coupled with new research on coral reef resilience and adaptability, may help buy some time for these indispensable ecosystems.
Corals and Climate Change
Corals are already facing a host of stressors—from pollution and overfishing to tourism and coastal development—but climate change puts corals at risk from rising temperatures and ocean acidification. The decline of coral reefs will have devastating consequences for the ocean, and for us.
While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and this trend shows no sign of slowing, meaning the implications for global sea level rise in this century could be more dramatic than earlier projections anticipated.
Climate change has many asking if the days of being able to summit the world’s highest peak are numbered.
In the light of recent varied efforts to focus public attention on the risks of climate change, we asked Earth Institute scientists what they want the public to understand about the issue and how they see their roles.
Melting glaciers, collapsing sea ice, water supplies under stress, increases in storm frequency, impacts on food supply — are we reading a synopsis of the IPCC report or messages from the future delivered through a software glitch? People around the world are posing this question.
As the arctic region loses ice in a changing climate, the economic and social tradeoffs are unclear. How will we balance economic, social and environmental functions? The Center on Global Energy Policy and the Consulate General of Canada in New York will examine these questions in a discussion on March 26: “Understanding the Arctic Resource Challenge: Canada and U.S. Perspectives.”
This week, we are launching a test of “IceTracker”—a tool that allows users to see the trajectories of Arctic sea ice forward or backward from any day between 1981 and 2012, as well as sea-ice speed, air temperature, water depth and the age of the sea ice.
