Worse than we thought: Global fossil fuel emissions of hydrocarbons are underestimated

by  UNIVERSITY OF YORK and the “blame Russia” department, February 26, 2018  in WUWT

Global levels of ethane and propane in the atmosphere have been underestimated by more than 50%, new research involving scientists at the University of York has revealed.

These hydrocarbons are particularly harmful in large cities where, through chemical reactions with emissions from cars, they form ozone – a greenhouse gas which is a key component of smog and directly linked to increases in mortality.

Temperature and Forcing

by Willis Eschenbach, July 13, 2017 in WUWT

Over at Dr. Curry’s excellent website, she’s discussing the Red and Blue Team approach. If I ran the zoo and could re-examine the climate question, I’d want to look at what I see as the central misunderstanding in the current theory of climate.

This is the mistaken idea that changes in global temperature are a linear function of changes in the top-of-atmosphere (TOA) radiation balance (usually called “forcing”).

Scrutinizing the carbon cycle and CO2 residence time in the atmosphere

by Hermann Harde, Global and Planetary Change, 24 February 2017


An alternative carbon cycle is presented in agreement with the carbon 14 decay.

The CO2 uptake rate scales proportional to the COconcentration.

Temperature dependent natural emission and absorption rates are considered.

The average residence time of CO2 in the atmosphere is found to be 4 years.

Paleoclimatic CO2 variations and the actual CO2 growth rate are well-reproduced.

The anthropogenic fraction of CO2 in the atmosphere is only 4.3%.

Human emissions only contribute 15% to the CO2 increase over the Industrial Era.

The Atmospheric Temperature Pause

The December 2016 global temperature anomaly from the average of two analysis is 0.20 °C above the average of 1981 – 2010. The large El Niño event is over and we wait to see if it will be followed by a La Niña event. The satellite measured temperature of the lower troposphere to the end of 2016 from the average of the University of Alabama in Huntsville and Remote Sensing Systems analysis is here. The temperature trend from December 1997 to December 2016 is 0.045 ± 0.043 °C/decade at the 95% confidence interval. The slope could be as low as 0.002 °C/decade. According to the satellite data, 2016 was a statistically insignificant 0.02 °C warmer than 1998, which was another strong El Niño year.
