We recently discussed this subject during our dialogue with Dr. Pielke Sr., and showed that using the CO2 radiative forcing estimate of Skeie et al. (2011) and the Padilla et al. (2011) 90 % confidence range for the transient climate sensitivity parameter, we can estimate a CO2 contribution of 0.64 to 1.28 °C, with a best estimate of 0.79 °C warming of average global surface temperature over the past ~ 150 years.

Finally, to revisit the question originally posed @ 203: Assuming the IEO2011 Reference case of «1 trillion metric tons of additional cumulative energy - related carbon dioxide emissions between 2009 and 2035», and given that this case equates to following RCP8.5 until 2035 as previously demonstrated @ 408, what increase in average global surface temperature relative to pre-industrial would result by 2035?

Although the IPCC climate models have performed remarkably well in projecting average global surface temperature warming thus far, Rahmstorf et al. (2012) found that the IPCC underestimated global average sea level rise since 1993 by 60 %.

On that basis our CO2 emissions would give rise to circulation changes affecting regional and local climates but not average global surface temperatures and the scale of their effect would be insignificant since our emissions comprise such a small portion of atmospheric mass which is the primary determinant of surface temperature.

Pointing to an oft - repeated formula, Mr. Djoghlaf said that each increase of one degree Celsius (1.8 Fahrenheit) in average global surface temperature resulted in the loss of about 10 percent of all known animal and plant species.

As was widely covered in the media, 2014 saw the highest annual average global surface temperature since records began, the report says:

IAMs typically come in two forms — either as simple climate models coupled with algorithms that translate increases in average global surface temperature into environmental and economic damages known as the social cost of carbon; or as more detailed Earth - system models with continually improving representation of physical impacts, coupled with economic models.

Victor also points out that average global surface temperatures doesn't fully represent the changing global climate.

The latest report by the IPCC, the international organization tasked with assessing the science of climate change and its impacts, predicts that in order to keep the increase in average global surface temperature under 3.6 degrees Fahrenheit (2 degrees Celsius), total future CO2 emissions can not exceed 1 trillion tons.

Annual average GCR counts per minute (blue - note that numbers decrease going up the left vertical axis, because lower GCRs should mean higher temperatures) from the Neutron Monitor Database vs. annual average global surface temperature (red, right vertical axis) from NOAA NCDC, both with second order polynomial fits.

For more than a decade international climate - policy discussions have revolved around a seemingly simple goal: Limit the rise in average global surface temperature to two degrees Celsius (3.6 degrees Fahrenheit).

If all nations fully achieve their Paris pledges, however, the average global surface temperature in 2100 is expected to be 3.3 degrees.

Of course, while short - term changes in sea level can be predicted fairly accurately based on the motions of the moon and sun, it is a lot harder predicting the ups and downs of the average global surface temperature — there is a lot of noise, or natural variation, in the system.

Although the rising average global surface temperature is an indicator of the degree of disruption that we have imposed on the global climate system, what's actually happening involves changes in circulation patterns, changes in precipitation patterns, and changes in extremes.

Enormous eruptions trigger El Niño events by pumping millions of tons of sulfur dioxide into the stratosphere, which form a sulfuric acid cloud, reflecting solar radiation and reducing the average global surface temperature, according to the study co-authored by Alan Robock, a distinguished professor in the Department of Environmental Sciences at Rutgers University - New Brunswick.

Implementing these measures in the New Policies Scenario would have the same impact on reducing the average global surface temperature rise in 2100 as shutting all existing coal - fired power plants in China.

Such reports could be on topics like climate change's influence on hurricanes, the so - called «pause» in the increase of average global surface temperatures or the climate implications of natural gas.

However, as we have previously discussed, the average global surface temperature over the first decade of this century has indeed warmed at a dampened rate.
