Fire and climate change: don’t expect a smooth ride

With fires still burning across New South Wales, it’s time to have a look at the role climate change might have played. Are the conditions we’re seeing natural variation, or part of a long term trend?

In fact, it doesn’t have to be one or the other.

Has bushfire risk increased due to climate change?

In research I did with colleagues earlier this year we looked at the Fire Danger Index calculated by the Bureau of Meteorology, and compared how it changed compared to temperature over time in Victoria.

South-east Australia saw a temperature change of about 0.8C when we compared temperatures before 1996 and after 1997. We know that it got drier after 1997 too.

We then compared this data to the Forest Fire Danger Index, to see if it showed the same pattern. We analysed fire data from nine stations in Victoria and did a non-linear analysis.

We found that fire danger in Victoria increased by over a third after 1996, compared to 1972-1996. The current level of fire danger is equivalent to the worst case projected for 2050, from an earlier analysis for the Climate Institute.

While it’s impossible to say categorically that the situation is the same in NSW, we know that these changes are generally applicable across south-east Australia. So it’s likely to be a similar case: fire and climate change are linked. Read the rest of this entry »

Industry Roundtable Context Paper

The recent VCCCAR Annual Forum featured an industry roundtable breakfast, chaired by Anne Barker of City West Water, to discuss industry and adaptation to climate change. The roundtable was attended by a couple of dozen people from industry, public policy and research. The discussion was really interesting, with industry representatives talking about the opportunities they were pursuing, how targeted R&D could keep down product prices (e.g., in housing construction) and what kinds of supporting policy they would like to see. There are clearly lots of opportunities for collaboration between research and industry but they won’t be successful without close cooperation.

As part of the roundtable, an Industry Roundtable Context Paper (pdf download) was prepared by Celeste Young and myself. We tried to keep it simple and direct. It’s scope is also limited to Victoria, but we hope it also is relevant in a broader context. The main points are (not rocket science!): Read the rest of this entry »
