Climate Change: A natural cycle or man-made?
According to a news report in the UK Telegraph, some 31 000 scientists have signed a petition that there is no evidence that human actions cause the catastrophic heating of the earth. The petition argued “There is no convincing scientific evidence that human release of … greenhouse gases 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.”
Renowned Scientists H. Schmitt and F. Singer supports this point of view. The reason you do not see many such scientists is because there is pressure on scientists who question global warming. Scientists just cannot get funding if they do not write in support of ‘global warming’.
UNIPCC inflated evidence
The UNIPCC [Intergovernmental Panel on Climate Change] inflated the evidence on the melting of glaciers in the Himalaya’s. “Glaciers in the Himalaya are receding faster than in any other part of the world and, if the present rate continues, the likelihood of them disappearing by the year 2035 and perhaps sooner is very high if the Earth keeps warming at the current rate” [http://www.ipcc.ch/publications_and_data/ar4/wg2/en/ch10s10-6-2.html]]. This claim of the likelihood being ‘very high’ means in the IPCC’s terms that there is a 90% chance that it will happen. This shows that at least some of the time in their report they were approaching the subject in an unscientific way and creating results to suit their political aim. It is especially worrying that the panel would increase a claim if they knew that the initial claim was not verified, and even more surprising that they would do so if they did not know where the initial claim came from or without any further research to back the increase in the claim.
The sun drives the global climate
It is the sun that is the driving force of our climate and so it makes sense that it has the biggest impact on our climate rather than anything that humans might be doing. The sun is therefore the most likely cause of global warming. Professor Henrik Svensmark, a physicist at the Danish National Space Center in Copenhagen argues that climate change is caused by solar activity.[[Louise Gray, ‘Copenhagen climate summit: global warming ’caused by sun’s radiation”, The Telegraph, 8/12/09, http://www.telegraph.co.uk/earth/copenhagen-climate-change-confe/6762640/Copenhagen-climate-summit-global-warming-caused-by-suns-radiation.html Solar activity, as determined by sunspot activity, is historically high being at its highest over the last 60-70 years for over 8000 years. Solar activity could affect climate by variation in the Sun’s output or potentially through having an effect on cloud formation.

A basic look at how climate scientists infer that man-made carbon gases are changing the climate, and how this view is contradicted by other climate scientists who are skeptics.
The speaker is a former science correspondent with an interest in reporting the facts, not the media hype. My thanks to 9thgate for checking my script for errors.
Please note that the animation of a photon striking a carbon atom is not meant to be visually correct, it is simply an illustration of CO2 absorbing energy and re-emitting it at a different wavelength. Given the limitations I have in making animations I could not spend an inordinate amount of time making a visually “correct” image of a photon striking an electron which moves into a different orbital plane, and even if I tried it would never be visually correct because on a quantum scale such an illustration is impossible. But thanks to all those who wrote in. The narration that accompanies the illustration is correct.
