IPCC report on ‘Managing the Risks of Extreme Events and Disasters’

Just ahead of the Durban climate change summit, the IPCC has released a major report focused upon extreme weather events and adaptation strategies it believes should be implemented to cope with them. (www.ipcc.ch – ‘Special Report’). The timing is likely to have been influenced by the expectation that final agreement on the USD 100bn climate fund can be reached during the summit. This fund would see developed countries combine to provide annual funding (the UN would like this to total USD 100bn) for climate change adaptation activities in developing nations.

We have read this report and found it disappointing. The main criticism would be that it attempts to cover too much ground and in doing so will leave readers confused. In particular the chapter on ‘Climate Extremes and Impacts’, which is really the crux of the matter, the examination ranges over every possible weather-related event, from coastal erosion, hurricanes/typhoons, to heat-waves, droughts and flooding. This inevitably leads to a great number of conclusions, probability levels and hedging around. Most people reading this section will end up very confused.

Climate Change – the emotive appeal

…we are not that comfortable with it.

There is clearly a disconnect, between the scientists and the public on the global warming theory; the science is difficult, it is multi-threaded, it does not lend itself to a black and white picture. Think about the CFC /Ozone Layer issue – nice, easy and one dimensional. You carry on emitting these chemicals, then the Ozone thins and eventually we all die of skin cancer. Satellite pictures even showed the ‘hole’ forming over Antarctica.

Global warming and associated climate change is a very different proposition. There are still a lot of ‘ifs’, ‘buts’ and ‘maybe thens’ and the time scales are relatively long ones. The average person will not read IPCC reports, still less the scientific papers that stand behind them. Public opinion is being formed on these matters by the press and other media. As the underlying science is not easy to grasp, this leaves the field open to the popularisers and the demagogues.
