[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.

UPDATE(2/23/18):The previous version of this post had improper latitude bounds for the HadCRUT4 Tsfc data. I’ve rerun the results… the conclusions remain the same. I have also added proof that ENSO is accompanied by its own radiative forcing, a controversial claim, which allows it to cause multi-decadal climate change. In simple terms, this is clear evidence the climate system can cause its own, natural, internally-generated climate changes. This is partly what has caused recent warming, and the climate modelling community has assumed it was all human-caused.Continue reading “A 1D Model Of Global Temperature Changes, 1880-2017”

It was declined by the Sun-News editor, because he was afraid that it would generate too many responses from the alarmist camp. We believe that this is nothing more than “soft censorship” another way to describe censorship, accompanied by a nonsensical explanation. Ed.]
Algernon D’Amassa is wrong by saying Hurricane Harvey was made worse by humans, mentioning sea level rise, warmer seas, and stronger storms.
No data show that Hurricane Harvey was made stronger by the use of fossil fuels; in fact, ready availability of, and use of, fossil fuels made a dangerous storm less so, as explained below, comparing Harvey with Galveston’s 1900 Hurricane.

It’s time to really cut, cut, cut ethanol and other renewable fuel mandates – maybe to zero.
The closest thing to earthly eternal life, President Ronald Reagan used to say, is a government program.
Those who benefit from a program actively and vocally defend it, often giving millions in campaign cash to politicians who help perpetuate it, while those who oppose the program or are harmed by it are usually disorganized and distracted by daily life.

Dr. Roy Spencer responds to an American Meteorological Society attack on DOE Secretary Rick Perry’s comments during an interview on CNBC’s “Squack Box” regarding climate change.
Dr. Roy Spencer
June 22nd, 2017
[This post originally appeared on Dr. Roy Spencer’s blog on 22 June 2017. Like many others, Dr. Spencer resigned in disgust from the American Meteorological Society some time ago because of their exaggerated statements regarding climate change. Now in an obvious display of unscientific hyperpbole, the AMS has attacked DOE Secretary Rick Perry. Dr. Spencer takes them to task for the wildly overstated claims regarding climate change that they made in their attack on the Secretary.
Dr. Spencer says,
“I am ashamed that the climate research community allows such pronouncements to be made. The AMS became a global warming advocacy group many years ago, and as a result it lost a lot of established members, including myself.” ]
Trump’s Paris decision challenges bad science, economics and energy politics behind treaty
In the wake of President Trump’s exit from the Paris climate treaty, reactions from other quarters were predictably swift, nasty, sanctimonious and hypocritical.
Al Gore paused near one of the private jets he takes to hector lesser mortals to say the action will bring “a global weather apocalypse.” Billionaire Tom Steyer got rich selling coal but called the President’s action “a traitorous act of war.” Actor-activist Mark Ruffalo railed that Trump has “the death of whole nations on his hands.” Michael Moore said the action was “a crime Continue reading “More rational policies in our future?”
