U.S. Strategy To Cut Carbon Emissions 80 Percent By 2050

While this year’s United Nations Marrakech Climate Change Conference was taking place in Morocco, strategic planning to combat climate change was also happening across the pond in the U.S. On November 16, the outgoing administration released the “United States Mid-Century Strategy For Deep Decarbonization.” Developed with input from stakeholders and in collaboration with Canada, Mexico, and other nations developing similar strategies, this plan explains potential pathways to reduce greenhouse gas (GHG) emissions by at least eighty percent by 2050.

Antarctica: More Than Penguins

Most homebuyers don’t think about Antarctica when buying beachfront property. But maybe they should. The 5.4 million-square-mile Antarctic ice sheet is melting, and scientists estimate that if it disappeared completely, sea level would rise by 200 feet. While no one expects complete melting to happen in the immediate future, competing pressures are increasing the rate of ice melt, whose impacts will be felt in varying ways around the globe – and could even affect that beachfront buy sooner rather than later. In addition to Antarctica’s globally significant role in sea level rise, ocean and atmospheric circulation, and carbon cycling, it has a unique ecosystem that offers myriad opportunities for scientific research. Last week, at a congressional briefing hosted by Columbia University’s Lamont-Doherty Earth Observatory (LDEO), scientists discussed the changing Antarctic and research opportunities in light of the National Academies of Sciences, Engineering, and Medicine’s strategic vision for NSF-supported research in Antarctica and the Southern Ocean over the next ten years.

Coast Guard Actions In The Arctic

The House Transportation and Infrastructure Committee, Subcommittee on Coast Guard and Maritime Transportation, held a hearing on the Coast Guard’s implementation capabilities in the Arctic to outline the state of play in the region.
