Australia (TGW) - Global warming is going to take a heavy toll
on Australia, already one of the driest parts of the world,
according to a new report released by scientists at the
Commonwealth Scientific and Industrial Research Organization
(CSIRO). Australia is likely to be hit harder because it is
already dry there. The key findings of the report include that
by 2030, temperatures will rise by about 1 degree Celsius over
Australia – a little less in coastal areas, and a little more
inland - later in the century. If emissions are low, warming of
between 1 ºC and 2.5 ºC is likely by around 2070, with a best
estimate of 1.8 ºC. Under a high emission scenario, the best
estimate warming is 3.4 ºC, with a range of 2.2 ºC to 5 ºC. The
report also indicates there will be changes in temperature
extremes, with fewer frosts and substantially more days over 35
ºC. Temperatures have already increased .9 degrees Celsius since
1950. At low emissions of greenhouse gases, warming of between 1
degree Celsius and 2.5 degrees w
