Earth’s ecosystems keep soaking up more carbon as greenhouse gases accumulate in the atmosphere, new measurements find. The research contradicts several recent studies suggesting that “carbon sinks” have reached or passed their capacity. By looking at global measurements of atmospheric carbon dioxide, the new work calculates instead that total sinks have increased roughly in line…

Some like it hot, including the plants living in South America’s tropical rain forests 56 million years ago. As global average temperatures spiked 5 degrees Celsius over a period of 10,000 years — a geologic blink of an eye — plant diversity in northern South America also soared, researchers report in the Nov. 12 Science.
