Recent US research (also quoted here) shows that less people believe that climate change is real compared to last year.
Less people now "believe" that climate change is real
Over the same period, there has been a comparable decline in the proportion of Americans who say global temperatures are rising as a result of human activity, such as burning fossil fuels. Just 36% say that currently, down from 47% last year.
Research in the UK and Canada shows similar trends.
Less people believe it but the effects of global waming are accelerating
So what do we have to do to convince people that we need to cut GHG emissions? It reminds me of the smoking debate. Both invoke public health issues. Both have solid science behind them. And for both, BELIEF was everything.
I know that many people have written about this before, but changing people’s attitudes and behaviour probably needs to be done using a behaviour-change model such as that used in health promotion and medicine.
For instance see these two abstracts:
The dynamics of belief in climate change and its risks in business organisations.
Climate change: Motivation for taking measure to adapt
Unfortunately the science alone is not enough. It may SEEM that way to scientists but it is not enough for the general public. We have to MARKET climate change and SELL it to the masses.
We have to if we are going to achieve meaningful change.
The anti-climate change lobby is crafting messages to achieve an emotional outcome – we have to as well.
So this conference is trying to do just that – and strangely enough it’s on next week: BEHAVIOR, ENERGY & CLIMATE CHANGE CONFERENCE. Looks like it’s too late to register to attend but you can download the program and all the abstracts (which together forms a sort of topic / study guide) plus there is limited webinar registration available until tomorrow.

According to an online report from The Sydney Morning Herald, climate change-related damage to Australia’s Great Barrier Reef will cost us some $37.5 billion during this century.
If greenhouse gas emissions are not reduced globally, the Great Barrier Reef is expected to be one of the first of Australia’s World Heritage sites seriously damaged. But chairman of the Great Barrier Reef Foundation Dr John Schubert warned that with climate change happening much faster than predicted, Australia must plan to ”adapt” the reef to save it from some level of damage scientists say is inevitable.
According to the article:
”There needs to be extra emphasis on the adaptation side,” said Dr Schubert, who is also the outgoing chairman of the Commonwealth Bank and sits on the board of BHP-Billiton and Qantas. He said the report by Oxford Economics was a conservative assessment of the losses if the reef was damaged by permanent bleaching.

Bleaching (due to higher water temperatures) is not the only threat facing coral reefs. With atmospheric CO2 levels rising fast, ocean acidification is fast becoming THE major threat to all marine ecosystems.
The oceans absorb a lot of the CO2 emitted by human activities. When it dissolves in seawater it forms carbonic acid – this makes the oceans more acidic.
Shell-forming sea creatures (including coral polyps) can only deposit calcium in their shells when pH is between a certain critical range (see diagram).And if they can’t harden their shells they can’t survive, or form coral reefs for that matter.
As the oceans become more acidic, it is likely that large areas will become less hospitable to marine life – this will damage ocean food webs significantly as many crustaceans (and related species) are food for fish and other animals higher up the food chain.
More about ocen acidification coming soon…

What is the Petition Project?
The Petition Project is presented as a list of people who do not “believe” (for want of a better word) in global warming:
We urge the United States government to reject the global warming agreement that was written in Kyoto, Japan in December, 1997, and any other similar proposals. The proposed limits on greenhouse gases would harm the environment, hinder the advance of science and technology, and damage the health and welfare of mankind.
There is no convincing scientific evidence that human release of carbon dioxide, methane, or other greenhouse gasses is causing or will, in the foreseeable future, cause catastrophic heating of the Earth’s atmosphere and disruption of the Earth’s climate. Moreover, there is substantial scientific evidence that increases in atmospheric carbon dioxide produce many beneficial effects upon the natural plant and animal environments of the Earth.
We are also told, that “31,072 American scientists have signed this petition, including 9,021 with PhDs”. That all seems to be in order, right? Well no, actually. There are some fundamental problems with the very concept behind the Petition, not to mention various other controversies surrounding it.
You can view this on the Petition Project’s website.
Appeal to Authority
The first problem with the Petition Project is that the concept behind it is a fallacy, known as an appeal to authority. The idea is that “these people are very clever, therefore they have authority which makes what they are saying worth something” (to paraphrase). When you read that there are 31,000 or so scientists who oppose global warming, you are supposed to think that because there are so many of them, and they are “scientists”, they must be right.
Presenting an argument based on how many people supposedly agree with it as evidence is flawed, but it does get worse…
Appeal to False Authority
If you look more closely at the qualifications of signers of the petition, you will see that:
The Petition Project classifies petition signers on the basis of their formal academic training, as summarized below. Scientists often pursue specialized fields of endeavor that are different from their formal education, but their underlying training can be applied to any scientific field in which they become interested.
Essentially, the majority of the signers have some kind of qualification in a scientific field, be it a Bachelor’s, Master’s or PhD. The problem is that, as science is such a vast field, you can spend your entire life studying one branch of science and still know absolutely nothing about another. For example, I am a physics student, and I can honestly say that I know nothing about medicine. I also wouldn’t expect an ecologist to understand the processes behind the formation of stars, for example.
This is precisely what the Petition Project does assume, though. If we look at the qualifications of the signers, we see that even medical doctors are eligible to sign. Take a look. Some of the more amusing backgrounds, that supposedly give these people enough special knowledge about global warming to deny its existence, include:
Mathematics – without a special interest in the climate, this is worthless in the field.
Physics – I have almost finished a Bachelor’s degree in Physics and there has been only one, optional course about “Environmental Physics”, so I can argue from experience that a degree in Physics does not necessarily equip someone with the information they may need to decry global warming.
Biology – unless there’s a large degree of specialisation of the effects of climate change on some biological variable (growth, change of ecosystems etc), this has no bearing on the subject.
Medicine – What?!
Aerospace Engineering – I happen to live with an Aeronautical Engineering student, who has had no training in any environmental subjects whatsoever.
Computer Science – see Aerospace Engineering
It is like asking celebrities what they think of the economy of Chad. They may be famous, and therefore carry some weight, but their opinions are nothing more than opinion. Asking “Dr X” what he thinks of the manufacture of steel may be all well and good, except that “Dr X” has a PhD in ancient history. He may be qualified in something, but it is misleading to assume that because he is a doctor of something, he must know everything about everything.
Controversy
In a previous incarnation of the petition, many fake names were discovered to have been added with the aim of showing the dubious methods by which the Petition Project gathered names. These have included an actor, a senator, a fictional character and a spice girl. It would appear that a number of names are duplicates, or belong to people who have died or have since changed their minds.
When the first petition was circulated to many American scientists, it contained a wad of paper claiming to be a research paper, which I would encourage you to look at. It was formatted in such a way as to resemble a paper published by the National Academy of Science (or so says my source. I have seen this claim elsewhere, also) which was misleading as the paper was not peer reviewed or even published.
The content of the paper itself is highly misleading (and, from what I’ve seen of it, quite amusing). For example, they show a graph showing a flat horizontal line, which shows that the number of hurricanes has not increased over the past however many years. This may be true, but as I have discussed, we wouldn’t expect it to. We expect the strength of the average hurricane to increase, but the number of them would stay approximately the same.
What they’ve done in this case, is argue something that was never in contention in the first place, and then use that argument to claim that their opposition are wrong.
To Sum Up
As I said before, the Petition Project is used very frequently on the internet by “climate change deniers”. I would of course encourage you to have an open mind to everything you read, but please don’t be taken in by this one. Its methodology is flawed, its motives are highly biased and its conclusions are misleading.
