Trees and climate change: Faster growth, lighter wood Trees are growing more rapidly due to climate change. This sounds like good news. After all, this means that trees are storing more carbon dioxide from the atmosphere in their wood and hence taking away the key ingredient in global warming. But is it that

There and back again: Mantle xenon has a story to tell Volatiles -- such as water, carbon dioxide and the noble gases -- come out of the earth's interior through volcanism and may be injected into the mantle from the atmosphere, a pair of processes called mantle degassing and regassing. The exchange controls
