Global warming is called Climate change now isn't it?
global warming is the cause of climate change
mebbe they should re-name it to 'global climate change'

You are right am3, more people, more arson, more careless smokers........we can't blame them for 60 million years of history though.

The effects of bushfires are not all detrimental to the environment, as fire generates regrowth and new life. In some eucalypt species, for example, fire is an essential part of the life cycle. For these plants, fire splits open seed pods, allowing them to germinate. Without fire, these species are unable to reproduce. Fire also encourages the growth of new grassland plants.

c'mon siggie, fires are a feature of every landscape. i'm sure nth and south america, africa and other landmasses where there was natural vegetation burnt on a variable basis too. this information in isolation means little.

The current NSW bushfires are being compared by fire officials, with the 2001 ones for severity.. that was over 10 years ago.
i heard the current bush fires had an extremely dangerous element - strong warm dry winds

But temperature change itself isn't the most severe effect of changing climate.
Changes to precipitation patterns and sea level are likely to have much greater human impact than the higher temperatures alone.
For this reason, scientific research on climate change encompasses far more than surface temperature change. So "global climate change" is the more scientifically accurate term. Like the Intergovernmental Panel on Climate Change, we've chosen to emphasize global climate change on this website, and not global warming.

So did the 2001, NSW bushfires.. I remember them well.. very hot, dry, strong gusty winds. Started on Christmas Day 2001.
