You're full of it JV.

How about proven your wild assumptions....!!!

You know what they say about computers and computer models don't ya....

Sh!t in..........Sh!t out.............LOL

I never said that
What I am saying is human activity is changing the current climate

Did you read to the end?

"Yet during the period 1980-2010, the solar activity was slowly  declining but both the Pacific and Atlantic oceans were both  positive correlating with a warm mode (AMO and PDO both positiv)], resulting in the global surface temperatures going up while the sunactivity was declining. It is no coincidence that during this last decade when the lagged
effects of the decline of last solar cycle# 23 and the decline of the ocean cycles as reflected by AMO and PDO indices, both of which are now in sync, that global temperatures should  also  decline. This makes sense to me and it disproves claims that solar effects were not responsible for the 1980 to 2010 global warming".

Or was it just selective reading?

Solar irradiance variation has been a main driver of climate change over geologic time, but its role in the recent warming has been found to be insignificant

Demonstrating that CO2, CH4 etc absorb IR photons requires neither computer nor model.

That the sun is quiescent—just refer to any solar observatory.

So what did AR4 say, it is the reference for the quote?

"and the possibility that the response to solar forcing could be underestimated by climate models."  - oh models

"However, estimates of some radiative forcings remain uncertain, including aerosol forcing and inter-decadal variations in solar forcing. " - hmmm - uncertainties.

Executive summary
------------------------------------------------
Some external influences, such as changes in solar radiation and volcanism, occur naturally and contribute to the total natural variability of the climate system."

http://www.ipcc.ch/publications_and_data/ar4/wg1/en/ch9s9-1.html#9-1-1

"The effects of forcing uncertainties, which can be considerable for some forcing agents such as solar and aerosol forcing (Section 9.2), also remain difficult to evaluate despite advances in research. "

" Uncertainties in external forcing were also reported, particularly in anthropogenic aerosol, solar and volcanic forcing, and in the magnitude of the corresponding climate responses. These uncertainties contributed to uncertainties in detection and attribution studies. Particularly, estimates of the contribution to the 20th-century warming by natural forcings and anthropogenic forcings other than greenhouse gases showed some discrepancies with climate simulations and were model dependent. "

They don't seem all that sure.

Sounds like your preaching about AGW. Not honest. 100% certainty.
