Here’s a comprehensive list of resources and information on global warming


The Definition of Global Warming:

There are various definitions available for global warming, here are a few that we think are particularly good.

From Wikipedia:

Global warming is the increase in the average temperature of the Earth’s near-surface air and the oceans since the mid-twentieth century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 years ending in 2005.

The Intergovernmental Panel on Climate Change (IPCC) concludes that anthropogenic greenhouse gases are responsible for most of the observed temperature increase since the middle of the twentieth century, and that natural phenomena such as solar variation and volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect afterward. These basic conclusions have been endorsed by more than 40 scientific societies and academies of science, including all of the national academies of science of the major industrialized countries.


From the Encylopdia of Earth:

The phrase global warming refers to the documented historical warming of the Earth’s surface based upon worldwide temperature records that have been maintained by humans since the 1880s.

The term global warming is often used synonymously with the term climate change, but the two terms have distinct meanings. Global warming is the combined result of anthropogenic (human-caused) emissions of greenhouse gases and changes in solar irradiance, while climate change refers to any change in the state of the climate that can be identified by changes in the average and/or the variability of its properties (e.g., temperature, precipitation), and that persists for an extended period, typically decades or longer.


Top Online Resources on Global Warming

The following is a list of websites that offer a lot of information on global warming.

Please also feel free to tell us about other resources we should include here.

  • IPCC: The Scientific Basis: link to the latest report issued by the United Nation’s Intergovernmental Panel on Climate Change, supported by the world’s leading climatologists.
  • RealClimate: A climate change blog, run by climate scientists.
  • G8 Climate Statement (PDF): here’s a joint declaration on the realities of global warming signed by the heads of the chief scientific advisors for all the G8 countries (China, Canada, Brazil, Russia, United States, Japan, Italy, India, Germany).

SUV's Outperform Hybrids in Energy Lifecycle: Interesting if True

An autmotive industry number cruncher called CNW Marketing Research has announced a study which claims that, “dust to dust,” high-polluting SUV's consume less energy than high-mileage hybrids. The CNW report claims to have calculated total energy consumption in the full lifecycle of an automobile, including construction and disposal, and concluded that SUVs have an energy advantage over gas-electric hybrids.

National Post Writers Overwhelmed by 2 Simultaneous Thoughts

Canada's national pretender - the National Post - is at it again, dismissing any notion of climate change on the grounds that while the weather has been warmer than usual in Calgary, it was colder than ever in Warsaw.

Inconvenient Truth: An Update

“When will we see a story about increasing levels of manmade greenhouse gases being a sign of progress? A story that points out that our use of affordable sources of energy continue to spur increases in global productivity, health, longevity, and quality of life in general? A story about the fact that the wealth that is generated by access to fossil fuels is just what will be required to develop and refine alternative energy technologies in the future?”

Accuracy in Media: A New Spin on the Spinners Spin

Accuracy in Media (AIM) is a New Right website that claims dedication to promoting “fairness, balance and accuracy in news reporting.” But this post gives a wonderful example of how twisted this “impartial” media monitoring has become. AIM assails MSNBC-TV host Keith Olbermann for suggesting that there might be a top-down, pro-Bush bias in his organization. Not possible, AIM claims, because NBC is owned by GE, which famously acknowledges that climate change is a real and pressing problem - in obvious contradiction to the Bush administration's position.

Media "balance" on global climate change reinterpreted

EMagazine recently interviewed Eugene Linden, author of The Winds of Change: Climate, Weather and the Destruction of Civilizations.

Linden does a nice job of explaining one of the most critical problems in sorting out the PR bias of climate change. The boldface question is from eMagazine. Linden's intelligent answer follows:

The Truth About Global Warming - Again

This headline - “The truth about global warming” - is one of the biggest hit grabbers on Google: people want to know.

In such circumstances, woe betide the ones who wind up on Susan Shelley's blogpost, which begins with an interesting piece of science and concludes with an encouragement that we all ignore the unprecedented scope of human impact on the earth's climate - and watch football. Scary.
