if people believe the climate is going to gradually change because of CO2 they may be wrong !! we need to take a closer look at drastic climate change that could happen in a very short period of time caused by the sun !!............OH THATS RIGHT LIBBS BELIEVE IT's ALL MAN MADE !!
WRONG..., AGAIN!!! That's the
"Big Lie" of the denier side, that the proponents ONLY consider GHGs. Nothing could be further from the truth. Why do you think the computer models are so complicated? Sort of trashes your argument, doesn't it?
What is the break down of the causes of AGW by the impact on the climate stated as a percent? What are all of the stated causes of AGW or warming in general and what percent is controllable by mankind.
That might be a good place to start the discussion of AGW.
Up until the 1950's I'd say

We can confirm this by comparing the calculation to empirical observations. From 1900 to 1950 the Earth's surface temperature warmed by about
0.4°C. Over that period, humans increased the amount of carbon dioxide in the atmosphere by about
20 parts per million by volume. This corresponds to an anthropogenic warming of:
dT = λ*dF = 5.35*(0.54 to 1.2°C/[W-m-2]*ln(310/295) = 0.14 to 0.32°C with a most likely value of 0.22°C
Therefore, the solar forcing combined with the anthropogenic CO2 forcing and other minor forcings (such as decreased volcanic activity) can account for the 0.4°C warming in the early 20th century, with the
solar forcing accounting for about 40% of the total warming. Over the past century, this increase in TSI is responsible for about 15-20% of global warming (Meehl 2004). But since TSI hasn't increased in at least the past 32 years (and more like 60 years, based on reconstructions), the Sun is not directly responsible for the warming over that period.
Solar activity & climate: is the sun causing global warming?
So since 1950...I'd say more like 100 percent of the warming caused by 2.7 watt/meter^2 green house gas forcing with 1.77 watts/meter^2 in 2009 being from co2. Hell looking at the first graph above...It is very hard NOT to say that the sun isn't a negative forcing on the climate system since 1950. I strongly believe since 2004 it has been!!!
Cosmic rays?

Haven't really changed...
Knowing damn well that the sun is likely a negative forcing....With the other factors such as increase in asian aerosols.
Of course this is IF wirebender is WRONG...A lot of what he brings to the table does make sense, but if he is right that is like back to square one in finding this forcing. 100 years of science and understanding of the climate thrown straight down the crappier.




Maybe he is right, but that would be a cluster **** on levels that reach around the earth 20 times over again. If he is he deserves the Nobel prize!
