Former EPA researcher new paper on climate change science and economics

A new paper on climate change science and economics was published in the International Journal of Environmental Research and Public Health, a peer-reviewed journal.  The paper is unusual from a number of different perspectives.

From a policy perspective, the paper's conclusions include the following:

· The economic benefits of reducing CO₂ emissions may be about two orders of magnitude less than those estimated by most economists because the climate sensitivity factor is much lower than assumed by the United Nations because feedback is negative rather than positive and the effects of CO₂ emissions reductions on atmospheric CO₂ appear to be short rather than long lasting.

· The costs of CO₂ emissions reductions are perhaps an order of magnitude higher than usually estimated because of technological and implementation problems recently identified.

· CO₂ emissions reductions are economically unattractive since the few benefits remaining after the corrections for the above effects are quite unlikely to economically justify the much higher costs unless much lower cost geoengineering is used.

· The risk of catastrophic anthropogenic global warming appears to be so low that it is not currently worth doing anything to try to control it, including geoengineering.

The EPA  estimates the effects on temp and sea level of lowering CO2.
"the results for projected atmospheric CO2 concentrations are estimated to be reduced by an average of 2.9 ppm (previously 3.0 ppm), global mean temperature is estimated to be reduced by 0.006 to 0.015 °C by 2100 and sea-level rise is projected to be reduced by approximately 0.06–0.14cm by 2100.- epw.senate.gov
