Evidence that global warming is largely caused by humans

A book I'd recommend is "The Skeptical Environmentalist" By Bjorn Lomborg who is a swedish climatologist.


It should be noted, mind you, that he is emphatically not a global warming denier. He does feel that we are barking up the wrong tree though, and on this point I agree with him.

A documentary by him, titled "Cool it," was recently on circuit here and is well worth the watch.

Yes not a denier at all but a rationale view from someone who should professionally speaking only be on one side of the fence.

Thanks for the link for the film 8)

When we consider Lungfish's theories http://en.wiped.org/Viki/Lungfish_cycles which in a nutshell suggests of changes in the shape of the earth's orbit, tilt and proximity to the sun we account for the many variations in climate over geological time when there were no people to "cause" anything.

Natural factors contributing to climate change have of course been taken into account by the IPCC, which has analysed diverse data from thousands of scientists in over a hundred countries during the last 26 years. The IPCC has never claimed that climate change is exclusively anthropogenic, but concludes that they are 95% confidant that human emissions of green house gases has a material impact on global warming. It is a popular decoy of AGW deniers to sow confusion about this issue by setting up a false dichotomy between natural and anthropogenic causes.

I have an honours in geology and did chemistry and environmental geochemistry as well. I am a complete fence sitter on the issue of anthropogenic global warming and find it hard to believe so many "non-scientist" have taken to global warming and pleading for carbon taxes hook-line-and-sincker.

There are much more pressing issues at hand, namely:
1) Water scarcity
2) Population growth and food security
3) Waste management

This global warming business and the fact that a bunch of stupid ignorant fools who read 1 psuedo-scientific article on global warming no believe they are experts.

I dont go around telling economics that: "As a geologist, I know that - after reading the Introduction to Economics for Dummies - to stimulate growth in South Africa's economy we would to kill all the butterflys and harvest fertilizer that emerges out of politicians mouths when they speak."

I am not a climate scientists, but that doesn't mean I cannot take a position of global warming. I trust in the consensus of scientists who are experts in climate science. In the same way that I am not a particle physicists, but don't have to remain neutral on the existence of the Higgs fields. I can put my trust the scientists running CERN. Almost all of my opinions and positions are based on trust.

The peer support in your reference can hardly be ignored.
