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

Regional Greenhouse Gas Initiative (RGGI) Program has not reduced emissions

“Positive RGGI program reviews have been from RGGI, Inc. (the program administrator) and the Acadia Center, which advocates for reduced emissions (see Stutt, Shattuck, and Kumar 2015). In this article, I investigate whether reported reductions in CO2 emissions from electric power plants, along with associated gains in health benefits and other claims, were actually achieved by the RGGI program. Based on my findings, any form of carbon tax is not the policy to accomplish emission reductions. The key results are:

• There were no added emissions reductions or associated health benefits from the RGGI program.

• Spending of RGGI revenue on energy efficiency, wind, solar power, and low-income fuel assistance had minimal impact.

• RGGI allowance costs added to already high regional electric bills. The combined pricing impact resulted in a 12 percent drop in goods production and a 34 percent drop in the production of energy-intensive goods. Comparison states increased goods production by 20 percent and lost only 5 percent of energy-intensive manufacturing. Power imports from other states increased from 8 percent to 17 percent.” click here

United States Greenhouse Gas Emissions declined in 2015

“The EPA attributed the overall decline to lower carbon dioxide emissions from burning fossil fuels, which itself came about because of less coal consumption in favor of natural gas, warmer winter weather that decreased heating fuel demand and lower electricity demand overall. ” click here

The USEPA GHG Endangerment Finding is Flawed

Regardless of whether you are for or against attempting to control long-term weather patterns (by the way, that’s what climate is) by regulating CO2 (a futile quest) the EPA endangerment finding is both technically and legally flawed. Even a simple analysis such as mine (e.g. here) came to that conclusion in June 2013. But more knowledgeable people than I (e.g. here) have submitted comments ignored by USEPA revealing the inadequacy of USEPA’s GHG endangerment finding. In her 2012 appeals court opinion Justice Janice Rodgers Brown explained the situation well (here) .

Alaska Warms, Methane Emissions are Stable

Sweeney, C., et al. (2016), No significant increase in long-term CH4 emissions on North Slope of Alaska despite significant increase in air temperature, Geophys. Res. Lett., 43, doi:10.1002/2016GL069292.

Continuous measurements of atmospheric methane (CH4) mole fractions measured by NOAA’s Global Greenhouse Gas Reference Network in Barrow, AK (BRW), show strong enhancements above background values when winds come from the land sector from July to December from 1986 to 2015, indicating that emissions from arctic tundra continue through autumn and into early winter. Twenty-nine years of measurements show little change in seasonal mean land sector CH4 enhancements, despite an increase in annual mean temperatures of 1.2 ± 0.8°C/decade (2σ). The record does reveal small increases in CH4 enhancements in November and December after 2010 due to increased late-season emissions. The lack of significant long-term trends suggests that more complex biogeochemical processes are counteracting the observed short-term (monthly) temperature sensitivity of 5.0 ± 3.6 ppb CH4/°C. Our results suggest that even the observed short-term temperature sensitivity from the Arctic will have little impact on the global atmospheric CH4 budget in the long term if future trajectories evolve with the same temperature sensitivity.

Jupiter Greenhouse Effect Due to Pressure, Not Greenhouse Gases

This post is very interesting. The argument has been that “global warming” will happen on earth just like on Jupiter if atmospheric carbon dioxide is continues to increase. This study refutes that argument.

“Prior work has confirmed the gravito-thermal greenhouse effect on 8 planets including Earth, and why this falsifies the theory of catastrophic man-made global warming. On the basis of this new paper, we find the gravito-thermal greenhouse effect also holds for Jupiter and that the pressure vs. temperature curve satisfies the Poisson Relation of the gravito-thermal greenhouse effect.” click here

Impact of CO2 on Climate has been Grossly Overstate

“How much will the doubling of CO2 in the air warm the global temperature? How do scientists take an accurate measurement of the temperature of the Earth’s atmosphere? Why can scientists better measure atmospheric temperatures from satellites than surface temperatures from ground thermometers?” click here for answers
