And yet... When science is asked what pulled our primordial asses out of 3 consecutive ICE AGES -- the best answer is not cow farts or SUVs -- it's "planetary wobble" and natural cycles.. It's all there in our oldest ice records.. A mile of ice over Albany started melting because of ___________?
Solar influences are NOT well known.. You cannot accurately measure solar output from the ground and separate Watts from atmospheric absorption.. We have BARELY a 20 year record of sat data.. And it's NOT the 11 yr sun spot cycles. It's the Total Solar Irradiation number that has increased the temp forcing at the surface by 1W/m2 since the mid 18th century..

The "squigglies" you see on the chart are individual "sun spot cycles".. But it's the TREND line of TOTAL irradiation that is ignored and discounted by the AGW clergy. 1W/m2 is approx 33% of the warming that we are trying to account for. You mention TSI --- "they" automatically start deflecting about sun spot cycles. WITH THE TSI removed --- of course... Just watch. Some cheesehead will post a "sun spot activity" chart within the next 10 posts...
And please note the "leveling off" of TSI towards the end of 20th century.. Popular AGW mythology today is just discovering the huge thermal "storage" effect of the oceans and even the land. They just discovered the diff btwn POWER (w/m2) and ENERGY (accumulated over time). So TSI is the ONE INDICATOR that would suggest a "pause" in the warming cycle that we are JUST NOW --- observing..
Now that is also "correlation" not a proof.. But that correlates BETTER with observations than just mere CO2 vs Temp for the past 20 years. Just with a delay due to "thermal inertia"....
We need ANOTHER 20 yrs of solar measurement from space to even BEGIN to understand the nuances of the PRIMARY source of thermal energy to the planet. Even a small shift in the SPECTRUM of solar radiation ---- could operate on the Greenhouse "window" and be a primary cause of warming or cooling.. What "color" is our sun??? How stable is THAT?
We don't have enough data to comment..
But let's ALL LEAP to conclusions based on fear and politics -----eh??
