[added comments] While carbon dioxide is a “greenhouse” gas and it does absorb energy in some infrared wavelength bands, many scientists will argue that its affect on average global temperatures have been considerably exaggerated by the proponents of catastrophic anthropogenic global warming. In order to derive effects extreme enough to be considered catastrophic, they have had to rely on strong positive feedback resulting in much larger effects than CO2 could produce without any feedbacks. Many prestigious scientists disagree with that and some even suspect the feedback is not only much less than estimated, but may even be negative.
One must always consider that contrary to that which is frequently stated by climate activists/alarmists, the debate is never over in science.
Las Cruces is home to New Mexico’s Land Grant school, New Mexico State University, ostensibly home of The Educated, but some of the climate pronouncements by climate alarmists here have proven to be terribly wrong.
Las Cruces, situated in southern New Mexico, is only an hour’s drive from El Paso, Texas, and is located both in the Mountain West and in the Chihuahuan Desert. As such, it lies in the area where cold season precipitation patterns are governed by the related weather events El Nino Southern Oscillation and its 60-year-long big cousin, the Pacific Decadal Oscillation.
It’s been long known that NASA1 GISS2 has been going through its historical temperature data archives and erasing old temperature measurements and replacing them with new, made up figures without any real legitimate reason.
This practice has led to the formation of new datasets called “adjusted” data, with the old datasets being called “V3 unadjusted”. The problem for global warming activists, however, was that when anyone looks at the old “V3 unadjusted” – i.e. untampered data – they often found a downward linear temperature trend. Such negative trends of course are an embarrassment for global warming alarmists, who have been claiming the planet is warming up rapidly.
There are numerous stories in the media about “Declining Arctic Sea Ice Extent.” This post is the story of what I found when I started looking into the specifics cited in some of those stories.
With a background in geology and as an operational meteorologist with 30 years in research and development, at the outset I became suspicious when periods of record cited as ‘lines of evidence’ were well short of the characteristic 60-year time period of naturally occurring weather events which influence my locale, New Mexico. The 60-year weather cycles which dominate North America are the Atlantic Multidecadal Oscillation for temperatures, and the Pacific Decadal Oscillation for rainfall, especially in the Mountain West of the USA, more of which is described here.

This article should be of particular interest to our forum in light of the recent discussions regarding progress, or lack thereof, in getting the skeptical point of view out to the general populace. One might conclude from this article that the skeptical community with help from climate economics may be seeing more success in changing minds than we might have thought. Ed.]
From Alberta to Australia, from Finland to France and beyond, voters are increasingly showing their displeasure with expensive energy policies imposed by politicians in an inane effort to fight purported human-caused climate change.
Skepticism about whether humans are causing dangerous climate change has always been higher in the United States than in most industrialized countries. As a result, governments in Europe, Canada, and in other developed countries are much farther along the energy-rationing path that cutting carbon dioxide emissions requires than the United States is. Residents in these countries have begun to revolt against the higher energy costs they suffer under as a result of ever-increasing taxes on fossil fuels Continue reading “Climate Politics Abroad Are Turning Decidedly Skeptical”
Suggestions from some CASF members to introduce visitors to the non-problem of catastrophic, human-caused, CO2-fueled “Global Warming” ( since the warming of the 1980s and 1990s stopped about 1998, the name needed to be changed to “Climate Change” ) have led us to a new feature, “New Visitors” short for, “New Visitors Start Here.”
The idea is to provide a short introductory paragraph (or two) and a series of links to take new visitors on a tour of many of the false claims of imminent climate catastrophe through links to short topics which demonstrate this folly. Our use of fossil fuels is causing an increase in atmospheric Carbon Dioxide, CO2 for short, but an elementary knowledge of high school chemistry, biology, general science and mathematics shows that the Continue reading “Another Feature for CASF, “New Visitors.””
