I refer to the letter Global warming theory nothing but hot air.

The writer seems to buy into the common arguments made by the climate change skeptics. He has openly questioned the neutrality of the hundreds of peer-reviewed scientific papers all affirming that Earth is warming up because of human activities.

He makes allegations that those research were funded by organisations that wanted to push a global warming agenda. He mentioned that there are many more scientists that had openly questioned the legitimacy of the global warming theory.

Then he urges us to Google ‘hard enough’, as he put it, to find these so called climate experts.

When he mentions climate experts, he probably meant the likes of Dr S. Fried Singer, who is an atmospheric physicist, a research fellow at the Independent Institute, professor emeritus of Environmental Sciences at the University of Virginia and former founding director of the US Weather Satellite Service.

Also an author of Hot Talk, Cold Science: Global Warming's Unfinished Debate. Singer is one of the leading global warming skeptics. However, he is far from independent and his stand is anywhere but neutral. He has worked with Exxon Mobil for over 20 years as a consultant.

Many of the scientists that had disputed Dr Michael E Mann's paper themselves are not independent. Most of them were funded by the oil and gas companies. Some were funded by the coal companies.

So, if employing the same argument used by the writer, if you Google ‘hard enough’ for these climate change skeptic scientists, you'd also find that most of them are - in more ways than one - connected to the oil and gas companies like Exxon Mobil.

In my humble opinion, I urge the writer to dig deeper. As a start, I provide this link to a site that has debunked some of the false arguments put forward.

Last but not least, I wonder if the writer knows that the climate change skeptics have changed their stand on climate change.

Their latest argument now is not that there is no global warming, but that global warming is actually good for human civilisation.
