Natural range of critically endangered western swamp tortoise increasingly untenable owing to reduced rainfall
Twenty-four of Australia's rarest tortoises have been released outside their natural range because climate change has dried out their remaining habitat.
The natural range of the critically endangered western swamp tortoise, Pseudemydura umbrina, has shrunk to two isolated wetlands in Perth's ever-growing outer suburbs, and a herpetological expert, Dr Gerald Kuchling, said reduced rainfall and a lowered groundwater table made those areas increasingly untenable.

Climate change may not be responsible for the recent skyrocketing cost of natural disasters, but it is very likely that it will impact future catastrophes. Climate models provide a glimpse of the future, and while they do not agree on all of the details, most models predict a few general trends. First, according to the Intergovernmental Panel on Climate Change, an increase of greenhouse gases in the atmosphere will probably boost temperatures over most land surfaces, though the exact change will vary regionally. More uncertain--but possible--outcomes of an increase in global temperatures include increased risk of drought and increased intensity of storms, including tropical cyclones with higher wind speeds, a wetter Asian monsoon, and, possibly, more intense mid-latitude storms. (For more information, see Global Warming: Potential Effects of Global Warming).
