Better to Have Global Warming than Global Cooling

Dr. Patrick Moore is a co-founder of Greenpeace. He says "there is no conclusive proof that human emissions of carbon dioxide are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years." Looking at the geological record, he writes, "Then an ice age occurred 450 million years ago when CO2 was still about 10 times higher than today." He notes that we are a "tropical species" and that warming would be far better than cooling.

Climate Science Is Not Settled

We are very far from the knowledge needed to make good climate policy, writes leading scientist Steven E. Koonin. The idea that "Climate science is settled" runs through today's popular and policy discussions. Unfortunately, that claim is misguided. It has not only distorted our public and policy debates on issues related to energy, greenhouse-gas emissions and the environment. But it also has inhibited the scientific and policy discussions that we need to have about our climate future.

A Climate Essay from Dr. Bill Gray

Essay by Dr. William Gray, climate scientist at Colorado State University. He writes, "there is considerable evidence that the global warming we have experienced over the last 30 years and over the last 100 years is largely natural." He says that many thousands of scientists do not accept the human-induced global warming hypothesis as presented by the IPCC reports. Climate models "have basic flaws". It is very difficult to obtain government grants to study natural climate change. "The normal scientific process of objectively studying both sides of a question has not yet occurred.".

Whatever Happened to Global Warming?

Matt Ridley remarks that several world leader will not be attending the UN summit of climate change, likely because they no longer consider it as an urgent threat. Ridley writes, "Global warming has stopped since shortly before this century began." Climate researcher have made many explanations for the 'pause' in warming, all of which imply that man-made climate change is so slow and tentative that it can be easily overwhelmed by natural variation in temperature—a possibility that they had previously all but ruled out. Researches have found that half of the late 20th century warming was due to a natural Atlantic Ocean cycle. The man-made warming of the past 20 years has been so feeble that a shifting current in one ocean was enough to wipe it out altogether.

Global Warming ‘Pause’ is More Than Temporary; Scientific Evidence

Friends of Science president Len Maier wrote in the Montreal Gazette that we dispute the claim by Dr. Shaun Lovejoy of McGill University that the current 16-plus-year slowdown in global warming is merely a pause. "The scientific method requires comparing predictions of your theory to the observational evidence, and the anthropogenic global warming theory as expressed in climate models fails the test." Lovejoy also falsely claimed there is a “consensus among scientists” of his views, but there is a wide range of views among climate scientists on the effect of CO2 emissions on global warming.
