US Emission Reductions Could Lower Temperature by 0.3 Degrees F by 2100

This article will estimate the temperature effect by 2100 of the US emission reductions from a business-as-usual model for the effects of climate change.  It will show that the reductions can be as much as 0.29 degrees F for the … Continue reading

Politics and the Fossil Fuel Industry versus the Laws of Nature and Economics

The fossil fuel backers and climate deniers now control both house houses of Congress, about two-thirds of state legislators and governors, and state attorney generals. All of these are set to oppose the EPA greenhouse gas pollution regulations and clean … Continue reading

Updated Lectures on Natural Gas Greenhouse Gas Limits, and Russian Natural Gas

I have updated the Greenhouse Gas version in the previous post to include a figure for how the comparison of methane versus carbon dioxide warming by weight over counts methane molecules by about a factor of three.  Instead of the warming of methane … Continue reading

Why Keep Including India When Comparing US with China Greenhouse Gas Emissions?

When industry and conservative writers or commentators oppose lowering US greenhouse gas (GHG) emissions, they always point out that China’s are now higher than US emissions, and they are supposedly doing nothing about it, and throw in India as third.  … Continue reading

Comparison of Greenhouse Warming for Leaked Methane versus CO2 from Coal

  There are two popular comparisons of greenhouse gas effects of leaked methane versus CO2 from burning fossil fuel.  They involve 20 or 100 year periods, and comparison of the gasses for the same weight. Neither time period has a … Continue reading

Replacing Old Coal with New Natural Gas Plants Can Reduce CO2 Production to Less Than a Third Per Plant

It is well known that since natural gas generates half the CO2 for the same energy produced as coal in current plants, that replacing old coal plants would reduce CO2 pollution by a half for the switched plants.  Those calculations … Continue reading
