In the way the statement was framed, yes there was 97% agreement amongst 50% peer reviewed climate scientists. http://tigger.uic.edu/~pdoran/012009_Doran_final.pdf 1. When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant? 2. Do you think human activity is a significant contributing factor in changing mean global temperatures? Results show that overall, 90% of participants answered “risen” to question 1 and 82% answered yes to question 2. In general, as the level of active research and specialization in climate science increases, so does agreement with the two primary questions (Figure 1). In our survey, the most specialized and knowledgeable respondents (with regard to climate change) are those who listed climate science as their area of expertise and who also have published more than 50% of their recent peer-reviewed papers on the subject of climate change (79 individuals in total). Of these specialists, 96.2% (76 of 79) answered “risen” to question 1 and 97.4% (75 of 77) answered yes to question 2. |

This seems to confirm that the sun will have less influence on the warming climate that we are experiencing. Is the geomagnetic AA a different source of energy or something. Isn't it the same thing as the sun? Isn't the geomagnetic AA just an aspect of the sun? |

http://en.wikipedia.org/wiki/Climate_sensitivity delta T = lamda * RF delta T = change in earth's surface temperature lamda = climate sensitivity RF = radiative forcing For a doubling of co2 we get 1*C without climate feedbacks RF would be 3.7watts/M*2 Taking from wiki here with feedbacks included there is a consensus that 3*C +-1.5*C then would give lamda= delta T/RF lamda = 1.5*C/(3.7w/m*2) = .4*C/(w/M*2) lamda = 3.0*C/(3.7w/m*2) = .8*C/(w/M*2) lamda = 4.5*C/(3.7w/m*2) = 1.2*C/(w/M*2) http://en.wikipedia.org/wiki/Climate_se ... l-age_data If Earth were to experience an equilibrium temperature change of ΔT (°C) due to a sustained forcing of ΔF (W/m2), then one might say that x/(ΔT) = (3.7 W/m2)/(ΔF), i.e. that x = ΔT * (3.7 W/m2)/ΔF x = ΔT * (3.7 W/m2)/ΔF ΔT= .8*C = industrial change in temperature since 1750 ΔF= 1.6w/M*2 after taking into account all the different forcings H = -.2w/M*2 ocean heat uptake x = ΔT times (3.7 W/m2)/(ΔF-H) x = .8*C times (3.7 W/m2)/ (1.6W/m2 -.2W/m2) = 2.1*C Rahmstorf qualified that there was a great deal of uncertainty in these calculations. Here is the low ball estimate and he is on the payroll of the oil companies with the co2 site Other experimental estimates Idso (1998)[21] calculated based on eight natural experiments a λ of 0.1 °C/(Wm−2) resulting in a climate sensitivity of only 0.4 °C for a doubling of the concentration of CO2 in the atmosphere. http://earthsky.org/earth/heartland-ins ... enial-gate Documents surreptitiously obtained from the Heartland Institute and then leaked to public websites in February 2012 disclosed the names of a number of donors to the institute – including the Charles G. Koch Charitable Foundation, tobacco companies Altria and Reynolds American, drug firms GlaxoSmithKline, Pfizer and Eli Lilly, Microsoft, liquor companies, and an anonymous donor who has given $13 million over the past five years – as well as the recipients of the institute’s largesse – climate skeptics including Craig Idso, physicist Fred Singer, Robert Carter, and Anthony Watts. The Heartland Institute maintains that the documents, which were first published on Desmogblog, were fraudulently acquired, and that the particular document detailing the alleged plans to influence school curricula is a forgery. |

I'll reply to your lengthy post tomorrow, Warmair. |
