Tag: carbon dioxide

[def from Wikipedia.]  Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth’s atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.[3] Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.

[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.

Climate Change: A Serious Threat to Science

by

Marita Noon

The current cold covering a large portion of the country has, once again, brought out the climate change alarmists with claims of “serious threat.”

Due to his respected position, as climate scientist at the University of California, San Diego Institution of Oceanography, Richard C.J. Somerville’s recent “Cold comfort” column was published in newspapers throughout the country.

In it, he grouses that the public doesn’t take the “consequences” of climate Continue reading “Climate Change: A Serious Threat to Science”

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 SFCTforcing 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”

History falsifies climate alarmist sea level claims

Seas have been rising and falling for thousands of years – without help from the EPA or IPCC

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”
