[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.
Skeptical modelers show a more realistic view of past, present, and future climate change that follows mostly natural temperature patterns. These models indicate a more benign climate outcome than do the IPCC models. Since they are able to bound the problem of cause and effect, they dramatically reduce the wide uncertainty range of expected global temperature increase due to atmospheric CO2 concentration.
When Alarmists say “climate change is real!” I think yes it is, but “real . . . what?” My perhaps flippant answer to that question is real normal, real natural . . . among a few. I think human caused climate change is real small. These are some of the real issues that I want to explore here.
The first point is that the Intergovernmental Panel on Climate Change (UN IPCC) climate models are actually not real at all. In fact based on the real data, they are turning out to be fairy tales. Based on the real data, more realistic models are now being developed by very qualified groups and individuals. The improvement in modeling results over those by the IPCC appear Continue reading “A Brief Look at Climate Models Developed by Skeptics”

Supposed threats to coastal military installations ignore science
By Bob Endlich
“Data from CO2 measuring stations and from the Sewell’s Point and all other tide gages may clearly refute these assertions, but NPR and its colleagues will not change their minds.”
“The Sewell’s Point tide gage shows that the rate of sea level rise has not changed since the gage was installed in 1927, and is unchanged from our use of fossil fuels. It’s time to base our policies on sound science, instead of manmade global warming fiction and scare stories.”
Anti-fossil fuel SCC relies on garbage models, ignores carbon benefits and hurts the poor
“If you could pick just one thing to reduce poverty, by far you would pick energy,” Bill Gates has said. “Access to energy is absolutely fundamental in the struggle against poverty,” World Bank VP Rachel Kyte and Nobel Prize Laureate Dr. Amartya Sen agree.

In science, one likes to have more examples than theories. – Dusan Djuric
Those words, spoken whimsically about cosmology, apply to climate science as well. The theory of the sensitivity of climate to the radiative forcing imposed by a doubling of carbon dioxide suffers from a lack of observed, repeatable examples. Paleo-climate studies carry with them the uncertainty of the proxy data and unmeasured assumptions on which they are based. Studies regarding the forcing from volcanoes and other transient events may not be repeatable for some time. However, Lindzen et. al. 1995 (link ) and Ramanathan and Inamdar in Frontiers of Climate Modeling, 2006 (link ) each have pointed out that the seasonal variation of earth temperature is quite large and possibly a surrogate for climate change. With this in mind, I set out to determine how the seasonal variation Continue reading “Seasonal Radiative Response”

Seas have been rising and falling for thousands of years – without help from the EPA or IPCC
Guest essay by Robert W. Endlich
Sea levels are rising rapidly! Coastal communities are becoming more vulnerable to storms and storm surges! Small island nations are going to disappear beneath the waves!
Climate alarmists have been making these claims for years, trying to tie them to events like “Superstorm” Sandy, which was below Category 1 hurricane strength when it struck New York City in October 2012, and Typhoon Haiyan, which plowed into the low-lying central Philippines in November 2013.
For alarmists, it does not seem to matter that the strength and frequency of tropical storms have been decreasing in recent years, while the rate of sea level rise has fallen to about seven inches per century. Nor does it seem to matter that the lost lives and property have little to do with the storms’ sheer power. Their destructive impact was caused by their hitting heavily populated areas, where governments had not adequately informed Continue reading “History falsifies climate alarmist sea level claims”
