effects of global warming on Australia ?

Answer 1

In general, the more extreme the climate already is the more pronounced the effects of global warming will be. Consequently the most dramatic effects have already been observed in extremely hot places like Africa and Asia and extremely cold places like Siberia and the Arctic.

Australia has the advantage of being a well developed nation and has the finances and resources to mitigate against many of the effects of global warming. For example, if global warming leads to drought in Australia and the crops fail then food can be imported, but if the same thing happens in Africa you have a famine and people die.

One effect is a gradual warming of average temperatures but this will be barely noticeable in Australia which has a variable climate. If for example it was 1°C warmer today than yesterday you'd probably not notice, you certainly wouldn't notice if this change occured over 60 years.

One thing that has been observed in Australia is an increase in the number of adverse weather and related events such as droughts and wild fires. No single event can be blamed on global warming but the general trend is an upward one and looks likely to continue.

Another noticeable effect in Australia is occuring in the oceans. As with many effects this isn't immediately noticeable unless you set out to look for it. The oceans are becoming more acidic and this is affecting the corals and marine life.
