The fundamental mistake of Svend Arrhenius

“Even a huge increase in CO2 or CH4  has minimal impact on climate.  H2O is far and away the dominant greenhouse gas on earth.” click here

Post from the past: “Justice Janice Rogers Brown gets it right on the GHG endangerment finding”

I posted this on December 12, 1012….the USEPA GHG endangerment finding was unwarranted (and incorrect).

“USEPA has embarked on issuing a variety of regulations to control emission of greenhouse gases using the Clean Air Act (CAA). This flurry of activity results from an earlier Supreme Court ruling that upheld USEPA’s GHG endangerment finding under the CAA.  The endangement finding was a clear stretch of the imagination by the court. A legal challenge to GHG rules was filed in the US District Court of Appeals, DC Circuit, and a panel of judges upheld their legality. A petition was filed requesting that the entire court rule on the appeal, which was recently denied. In her desent, Justice Janice Rogers Brown provides a good explanation of why the Supreme Court erred in their ruling on the GHG endangerment finding, which indeed they did. The broad expanse of the term “pollutant” in that ruling is well-beyond the original context and intent of the Clean Air Act statute.

I have provided the full written dissent of Justice Brown below. As during the 1990s in litigation involving the Safe Drinking Water Act, the prevailing opinion explained by Sentelle provides political cover for a lawless agency (USEPA), rather than recognizing and honoring the rule of law as intended by the CAA. If congress intended GHG emissions to be regulated, congress could have explicitly enacted legislation to do so. (Click here for the full ruling.)

Warming radiation from Green House Gases counterbalanced by surface cooling from increased evaporation

“And how does this compare to the warming from increased longwave radiation due to the additional CO2? Well, again, the calculations are in the endnotes. The answer is, per the IPCC calculations, CO2 alone over the period gave a yearly increase in downwelling radiation of ~ 0.03 W/m2. Generally, they double that number to allow for other greenhouse gases (GHGs), so for purposes of discussion, we’ll call it 0.06 W/m2 per year.

So over the period of this record, we have increased evaporative cooling of 0.10 W/m2 per year, and we have increased radiative warming from GHGs of 0.06 W/m2 per year.

Which means that over that period and that area at least, the calculated increase in warming radiation from GHGs was more than counterbalanced by the observed increase in surface cooling from increased evaporation.” click here

 

Greenhouse gas emissions decrease during first year of Trump Presidency

“The Environmental Protection Agency (EPA) released a report on Wednesday which found greenhouse gas emissions decreased during President Donald Trump’s first year in office.click here

US reduced greenhouse gas emissions more than European countries

“Take a wild guess what country is reducing its greenhouse gas emissions the most? Canada? Britain? France? India? Germany? Japan? No, no, no, no, no and no.” click here

Greenhouse gas emissions are dropping in the United States, rising in Europe

“New reports show that greenhouse gas emissions are plunging in the United States and rising in Europe—and the drop in the U.S. is due to falling costs of renewable energy and natural gas.” click here

Climate sensitivity, global warming potential calculations distorted by small denominators

“At this point, it is crucial to observe that every other gas is compared to CO2 to determine its GWP value. In other words, whatever GWP value is determined for CO2, that value is re-set equal to 1, so that the calculation of GWP for a gas produces a number compared to CO2. The slope of the absorption curve for CO2 becomes the denominator of the calculation to find the GWP of every other gas.” click here
