Global warming alarmism is not science. It is a toxic combination of pseudo-religion and totalitarian politics. To the extent that there is any debate over climate science–the alarmists run from debate like vampires fleeing garlic–the “skeptics” always win. If you want to follow climate science controversies in a rigorous but accessible fashion, check out the Science and Environmental Policy Project’s web site. Among other things, it features a weekly update on matters relating to the global warming debate.
This week’s SEPP newsletter includes an excellent piece by Dr. Harrison “Jack” Schmitt, a former United States Senator from New Mexico as well as a geologist and former Apollo astronaut who currently is an aerospace consultant. Dr. Schmitt reviews some of the basic evidence that the alarmists try to wish away. You really should read it all; here are some excerpts:
Policy makers at the head of government in the United States and elsewhere apparently want to believe, and to have others believe, that human use of fossil fuels accelerates global warming. They pursue this quest in order to impose ever greater and clearly unconstitutional control on the economy and personal liberty in the name of a hypothetically omnipotent government. There exists no true concern by the President or Congressional Leadership about the true effects of climate change – only a poorly concealed, ideologically driven attempt to use conjured up threats of catastrophic consequences as a lever to gain authoritarian control of society.
There has been an absolute natural increase in global surface temperature of half a degree Centigrade per 100 years (0.9 degrees Fahrenheit) over the last three and a half centuries. Observational climate data and objective interpretations of those data strongly indicate that nature, not human activity, exerts the primary influence on this current long term warming and on all global climate variations. Human influence through use of fossil fuels has been and remains minor if even detectable. Claims to the contrary only find support in highly questionable climate models that fail repeatedly against the reality of nature. What, then, stimulates historically and geologically observed, sometimes slow and sometimes radical, changes in climate?
The primary alternative hypothesis to human-caused global warming is natural climate change driven by the Sun. … As many scientists have documented, the position and orientation of the Earth in its orbit around the sun, and the Sun’s variable influence and activity, determine weather and climate. Seasons vary because of changing solar energy input in annual response to the varying orientation of Earth’s Northern and Southern Hemispheres. … Further, variations in solar radiation received by the Earth correlate with short-term variations in Earth’s weather, based on the slow movement of loops called “Rossby waves” in atmospheric jet streams.
