Over the past decade, the Arctic has warmed by 0.75°C, far outpacing the global average, while Antarctic temperatures have remained comparatively stable. As Earth approaches 2°C warming, the Arctic and Antarctic may reach 4°C and 2°C mean annual warming, and 7°C and 3°C winter warming, respectively. Expected consequences of increased Arctic warming include ongoing loss of land and sea ice, threats to wildlife and traditional human livelihoods, increased methane emissions, and extreme weather at lower latitudes.

Seeds of Change: Calestous Juma died on December 15th

Colleagues said he tweeted more than any professor they knew, and Calestous Juma’s tweets covered a swarm of things. Income inequality, and a free-trade area for Africa, you might expect. Those were the subjects he taught at Harvard: getting poorer countries, especially in Africa, to grow and thrive was the obsession of his life. But he also tweeted about a wheelchair that could climb stairs, the increasing size of steaks, and the maximum number of goats seen eating up in a tree. He was extra-delighted to send out a New York Times editorial, from 1878, about Thomas Edison’s new “aerophone”: “Something ought to be done about Mr Edison, and there is a growing conviction that it had better be done with a hemp rope.”
