Predicting the response of the Amazon rainforest to persistent drought conditions under current and future climates: a major challenge for global land surface models
major challenge global land surface models
2014/12/19
While a majority of global climate models project drier and longer dry seasons over the Amazon under higher CO2 levels, large uncertainties surround the response of vegetation to persistent droughts i...
The discovery of musky rat-kangaroo fossils has prompted experts to call for better protection of tropical rainforests after new links show the tiny marsupial cannot survive outside that environment.
