In the early fall 2010, over 10,000 walruses were spotted on the Northern coast of Alaska. Fischbach attributes their presence onshore to the Arctic’s melting sea ice.
From above, the treetops in the Amazon rainforest might look remarkably uniform. But different regions of the rainforest might store very different amounts of carbon.
It might be 10 years before we know the impact on wildlife of the Deepwater Horizon oil spill in the Gulf of Mexico. Sensitive coastal marshes especially.
Dr. Lefsky said that taller the trees in a forest, the more carbon is stored in that forest. This map will help scientists figure out what places in the world are holding onto a lot of carbon.
Scientists have discovered another ocean region swirling with plastic debris - like the notorious North Pacific Garbage Patch. But this one's in the Atlantic.
Polar ice sheets at the poles might be losing ice half as fast as previous high-end estimates. Scientists say this doesn't yet change projections of sea-level rise.
