Global Warming - How good is the evidence?

I am teaching Global Warming this term.  It is clear to me that apart from the yahoos and the corporate disinformation campaigns, there is some genuine scientific disagreement on this topic -- whether it's happening at all, whether it's caused by humans, etc.  Do you have an informed position on this topic?

The way I understand it, everyone accepts the proof of global warming, or at least that temperatures are going up. It is pretty hard to refute. Then again, people deny the Holocaust too. What people argue about is whether or not humans have caused global warming, and that's harder to prove.

In my opinion, and that of virtually the entire world scientific community, the evidence for global warming and climate change is conclusive.  Wander past the homepage of the IPCC, which has been studying its effects for years.  They have published their research findings in both formal and layman's terms.  The evidence is overwhelming.  Anyone who does not believe it at this point, simply doesn't want to believe it.

I think looking at the evidence we have to believe the majority of scientists who state that global warming does exist and it is having a detrimental effect on our world and future. Although it is always important to look at such topics from a variety of angles, I think debate has gone on for far too long and has reached the point where it is being used by individuals to stop constructive action and as an excuse to maintain the planet-killing status quo that exists at the moment.

Isn't it so interesting to hear both sides of the story?  Because most of my research in this arena (for my own personal knowledge) revolved around proving Global Warming to be true, I thought it would be fun to read a book revealing those in the science world who disagree.  Therefore, let me suggest a book to you:  The Deniers, by Lawrence Solomon.  An interesting read, to say the least!

Global warming is definitely attributable to human activity, particularly the ones that cause emission of carbon-di-oxide (CO2) in the atmospheres and reduction of forests. When the content of CO2 and some other gases in the atmosphere increases  it acts as some kind of insulation layer around the Earth and prevents it from losing enough of the heat received from the Sun.

When we burn fossil fuel like coal and gasoline to run our industries, drive our cars, heat our homes and other similar activities we emit CO2. In the process of industrialization and Urbanization we also cut trees. We also cut trees to provide raw material for many industries including paper making. This also adds to the global warming as trees absorb sunlight as well as CO2 in the air.

A god source for more detailed and authentic information on global warming is Europa Website of European Union.

Here are some genuine independent scientists who believe that current climate changes are natural as opposed to man-made. But they are the minority. Here are more wiki links.

Global warming Global warming conspiracy theory Global warming controversy List of authors from the IPCC AR4 WGI report List of climate scientists Oregon petition Scientific opinion on climate change Scientific consensus

My belief is that it is very probable mankind is adversly changing the climate. To ignore that because it might not be is a very irresponsible, high-risk strategy. The mature action would be to take the highly convincing evidence at face value and take steps to protect our habitat.

The IPCC is the centralisation point for all scientific research and international governmental activity relating to Climate Change (CC). They are fully endorsed and approved by the UN and National Governments. They are the most important, global information provider on CC

 From their site...

The IPCC was established to provide the decision-makers and others interested in climate change with an objective source of information about climate change. The IPCC does not conduct any research nor does it monitor climate related data or parameters. Its role is to assess on a comprehensive, objective, open and transparent basis the latest scientific, technical and socio-economic literature produced worldwide relevant to the understanding of the risk of human-induced climate change, its observed and projected impacts and options for adaptation and mitigation. IPCC reports should be neutral with respect to policy, although they need to deal objectively with policy relevant scientific, technical and socio economic factors. They should be of high scientific and technical standards, and aim to reflect a range of views, expertise and wide geographical coverage.

While there is debate about the nature, extent and impact of CC, there is very little genuine research that completely rejects man-made CC. There are lots of links from here...
