A few days ago I blogged about a letter signed by over 100 experts of various fields to the United Nations, which said that attempting to stop global warming was futile and that the IPCC process was flawed (see below). There was also another letter to the United Nations, that was signed by nearly 200 scientists which strongly urged immediate action by leading goverments to combat global warming. To be fair, I should have linked to both letters in the initial blog, which would have provided a more balanced post in which you could compare the letters. To make up for my mistake, here is a summary of what was written in that letter......

The letter starts out by addressing the 2007 IPCC report which states that we are now at least 90% certain that human activities are contributing to a warming planet and that many millions of people will be at risk from extreme events if the trend is not halted soon.

--The letter states that global greenhouse gas emissions need to be reduced by 50% below their 1990 levels by 2050.

--Greenhouse gas emissions in the long run need to be stabilized at a level well below 450 ppm.

--Global emissions must peak and decline in the next 10-15 years in order to stay below the expected 2 degrees celsius increase.

TalkClimateChange.com did a nice post a couple days ago in comparing the two letters. Here is the link.

Here is the earlier post from Saturday which I titled "Attempting to stop Global Warming is Futile and a Mistake, says letter to the UN

Global warming is a natural phenomenon that has affected humanity through the ages and it is not possible to stop climate change. The Bali and the IPCC process is a mistake, and will ultimately be futile. These are the conclusions from an open letter to the United Nations Secretary General Ban Ki-Moon, which was signed by more than 100 specialists from around the world with expertise ranging from climate science to economics and biology.

The letter, which was assembled by Robert M. Carter, professor at the Marime Geophysical Laboratory of James Cook University in Australia, argues against the existence of consensus and rejects claims of abnormal climate change. The letter also disputes the IPCC process and claims new research has emerged making the IPCC reports "materially oudated".

The IPCC's Summaries for Policy Makers are the most commonly read IPCC reports among politicians and non-scientists, yet, according to the letter, these summaries are prepared by a small core writing team with final drafts approved by government representatives. A great majority of IPCC contributers, reviewers and other qualified scientists are not involved in the preparation of the documents.

The letter, which was posted on the National Post from Canada, also states that the IPCC's conclusions are quite inadequate as justification for implementing policies that will markedly diminish future prosperity. Also, it is not established that it is possible to significantly alter global climate through cuts in human greenhouse gas emissions.

By the way, one of the signers to this letter was Dr. Fred Singer, who is featured today in a video question and answer with our own Katie Fehlinger just below. Here is the link to all of the signatories of this open letter.
