How does the Sun drive climate change? Guest Post by Javier The dispute between scholars that favor a periodical interpretation of climate changes, mostly based on astronomical causes, and those that prefer non-periodical Earth-based explanations has a long tradition that can be traced to the catastrophism-uniformitarianism dispute and how the theory of ice ages (nowContinue reading “It’s the gradient, stupid!”

An Assessment of the 4th National Climate Assessment
By Andy May The U.S. Fourth National Climate Assessment (NCA4) Volume II is out and generating a lot of discussion. Volume II, Impacts Risks and Adaptation in the United States to climate change can be downloaded here (Reidmiller, et al. 2018). Volume I, published last year, on the physical science behind the assessment is hereContinue reading “An Assessment of the 4th National Climate Assessment”

We can eliminate fossil fuels, no problem!
By Andy May French President Macron has implemented a new fuel tax to discourage drivers from burning fossil fuels in their cars. The resulting higher fuel prices have caused more than 250,000 people to protest, with some rioting. Polls indicate that 62 percent of the population think that prioritizing man-made climate change over fuel pricesContinue reading “We can eliminate fossil fuels, no problem!”

Environmental Collusion
By Andy May Chris Horner of the Competitive Enterprise Institute (CEI) released a report (Law Enforcement for Rent) in August of 2018 detailing an unprecedented level of cooperation between the state governments of Maryland, Massachusetts, New York, Oregon, Washington and the District of Columbia. In these states, environmental groups and major liberal donors directly fundContinue reading “Environmental Collusion”

How constant is the “solar constant?”
The IPCC lowered their estimate of the impact of solar variability on the Earth’s climate from the already low value of 0.12 W/m2 (Watts per square-meter) given in their fourth report (AR4), to a still lower value of 0.05 W/m2 in the 2013 fifth report (AR5), the new value is illustrated in Figure 1. TheseContinue reading “How constant is the “solar constant?””

Interview with William Happer on Climate Change
By Andy May While attending the latest Heartland Conference on energy in New Orleans, I ran across a pamphlet that contained an excellent TheBestSchools.org interview with Professor William Happer, the famous Princeton physicist, on climate change. As described in the pamphlet, Professor Happer has been heavily involved in climate science since before he was aContinue reading “Interview with William Happer on Climate Change”

Stephen, Why Global Warming is not a problem
By Andy May The following is a quote from my book Climate Catastrophe! Science or Science Fiction? “99.9 percent of the Earth’s surface heat capacity is in the oceans and less than 0.1 percent is in the atmosphere. Further, CO2 is only 0.04 percent of the atmosphere. It beggars belief that a trace gas (CO2), in anContinue reading “Stephen, Why Global Warming is not a problem”

Commuting to work: car, train or bus?
By Andy May The United States Department of Transportation tells us in their online report “Public Transportation’s Role in responding to Climate Change” that we should use public transportation to reduce our greenhouse emissions. This claim is also made in Time’s “Global Warming Survival Guide.” Even the CDC (Centers for Disease Control and Prevention) recommendedContinue reading “Commuting to work: car, train or bus?”

Poverty and Energy
By Andy May Poverty and access to energy are closely related. Although it probably isn’t possible to show that access to energy is the key reason so many have been lifted out of poverty in recent decades, the data and logic suggests that this so. In the United States, the average person uses about 300Continue reading “Poverty and Energy”

Does Global Warming increase total atmospheric water vapor (TPW)?
By Andy May Some have speculated that the distribution of relative humidity would remain roughly constant as climate changes (Allen and Ingram 2002). Specific humidity can be thought of as “absolute” humidity or the total amount of water vapor in the atmosphere. We will call this amount “TPW” or total precipitable water with units ofContinue reading “Does Global Warming increase total atmospheric water vapor (TPW)?”
