(03/26/2007) Many of the world's local climates could be radically changed if global warming trends continue, reports a new study published in the early online edition of the journal Proceedings of the National Academy of Sciences. The authors warn that current climates may shift and disappear, increasing the risk of biodiversity extinction and other ecological changes.
Extinction, like climate change, is complicated
(03/26/2007) Extinction is a hotly debated, but poorly understood topic in science. The same goes for climate change. When scientists try to forecast the impact of global change on future biodiversity levels, the results are contentious, to say the least. While some argue that species have managed to survive worse climate change in the past and that current threats to biodiversity are overstated, many biologists say the impacts of climate change and resulting shifts in rainfall, temperature, sea levels, ecosystem composition, and food availability will have significant effects on global species richness.
