The Sun and Global Warming
Ive been frightening myself all week by reading "Climate Code Red: the Case for Emergency Action" by David Spratt and Phillip Sutton. On the back cover it says "This meticulously documented call-to-action reveals extensive scientific evidence that the global warming crisis is far worse than officially indicated- and that we're almost at the point of no return" Whats really frightening is that things appear to be changing more rapidly than was predicted even as recently as last year when the IPCC Report was issued, but it is that IPCC Report which Governments like our own here in Australia are using as a guide to plan their response to Global Warming.
On the websites and Blogs that Ive been trawling all week for material for my next Blog, I frequently came across Warming Denialists who rubbish the IPCC saying its just a political body and couldnt produce anything other than whatever its masters deemed was politically correct, so they breezily dismiss its recommendations. But what is the IPCC?
The IPCC (The Intergovernmental Panel on Climate Change) was established by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) to assess scientific, technical and socio-economic information concerning climate change, its potential effects and options for adaptation and mitigation. Its first Report was issued in 1990. Its assesment reports are written by hundreds of scientific experts from many fields, and represent over 40 countries. These reports are required to be Policy "Neutral" and contain no recommendations. Each report takes more than 3 years to prepare and goes through multiple stages of independent expert and government review, "the most thorough review process undertaken for any scientific assesment" acccording to Professor David Karoly, Professor of Meteorology in the school of Earth Sciences at the University of Melbourne. So Governemnts are right to take the IPCC Report seriously - it is an important and authoritative document - except for one thing: its Five years out of date! Its out of date because it takes a year or two to do the research, another year or so to get the research published and then another three for the IPCC to scrutinise it and analyse it along with all the other material and eventually write a report that everyone agrees on. There are many environmentalists who regard this process as not only too slow but too subject to the need for consensus and compromise resulting in a report that is too weak. Hence the need for books like Climate Code Red which attempt to speed up that process.
What I was going to do was condense some of the central issues into a few blogs - but I realise now that its an impossible task- for me at least - the issues are huge and interconnected and there is much thats unresolved. Instead I submit this Introduction and link to an excellent Review in New Scientist called " Climate Change: A Review for the Perplexed
"Our planet's climate is anything but simple. All kinds of factors influence it, from massive events on the Sun to the growth of microscopic creatures in the oceans, and there are subtle interactions between many of these factors.
Yet despite all the complexities, a firm and ever-growing body of evidence points to a clear picture: the world is warming, this warming is due to human activity increasing levels of greenhouse gases in the atmosphere, and if emissions continue unabated the warming will too, with increasingly serious consequences.
Yes, there are still big uncertainties in some predictions, but these swing both ways. For example, the response of clouds could slow the warming or speed it up.
With so much at stake, it is right that climate science is subjected to the most intense scrutiny. What does not help is for the real issues to be muddied by discredited arguments or wild theories.
So for those who are not sure what to believe, here is our round-up of the most common climate myths and misconceptions.

Hitler and Global Warming
Maybe that's what you re thinking too, but consider these words from "Climate Wars" by Gwynne Dyer, a book only just published that I bought on Saturday:

Climate Change denialists are so Wrong
The first thing I realized was that Climate Deniers are an extreme minority, but they make a lot of noise, make arguments that are simple and sound plausible to most of us, and thereby create an impression that there is still an argument going on about whether or not Global Warming is happening and is a threat. The trouble is most of us are not scientists, and we can easily be impressed by glib arguments and have no way of knowing if theyre really valid. The same thing happens with creationists who try to give the impression that in Science there is still room for doubt about the fact of evolution : there is none - but which of us is actually qualified to know that, for example their often repeated claim that evolution must be wrong because human and dinosaur footprints can be found together is simply not true? There are also people who still believe that the Earth is Flat - its not- but try to unravel the arguments they make! There are others who believe that "9/11" was a US Government Conspiracy- try and argue against that monstrous lie and see where you get against fanatics whose agenda is not about Truth but about being Right!
