CU-Boulder researcher links volcanic activity to recent dip in global warming

Mar 3, 2013 Full story: Colorado Daily 8

A study led by researchers at the University of Colorado has determined that the pace of planet warming in the first decade of this century was slowed by volcanic activity, and not by industrial activity in Asia, as was previously believed.

Was not expecting volcanism to have been anything more than background.

The absence of anything other than background volcanism probably does have a bit to do with the current La Nina though.

The current slight dip in global temperatures (over last 5 years had more to do with the solar superminimum where we had 3 years of a very small blank sun coupled with relatively low industrial output due to a depression.

Sad to say: volcanism merely irritating for air travel but not responsible for a cooling trend.

Toxic topix AGW denier 'fun farts' uses sunspot numbers 'to show global cooling', altho sunspot number reduction shows no accurate quantitative reduction in TSI. But yes, for 3+ years, the TSI was at a 100 year record low, 1 to 2 parts per 1000 below average solar output AND below average TSI for years before the minimum.

It was the sun.

Again, just like CO2, particulate matter can block TSI. In this case, particulate matters blocks TSI from reaching the earth. Our sun had very low activity for a few years during the 2000s, since 2003. More particulate matter would have blocked the lower incoming values allowing even less of the already low values to reach the earth.

Our sun is still in low value. Predictions are that this solar cycle will be about 14 to 17 years in length. It has already hit the soalr max of the cycle in both the SIDC (11-11) and SSN (2-12) values.

If the prediction is correct, we will have between 10.5 to 13.5 more years of very low activity.

Here's the experiment we can observe. Will reduced solar activity cause a reduction in surface temperatures? Will CO2 continue to rise even with lower solar activity? It won't take long to see the impact if the sun does what is predicted. Ten years from now we will have a whole lot more answers than we have now.

Again,'fun farts' uses sunspot numbers but not quantitative TSI numbers. He does that to side-track the issue that solar energy reduction is small. As stated in other posts, the decade of the 2000's solar 100 year record TSI low was only 1 to 2 parts per 1000 below normal.

The 2000's which included the 100 year record low TSI, did not show dramatic lowering of global temperatures, most certainly, not back to the temperatures of the early 20th centuries. Matter of fact........ not one month in last 350+(?) months has retreated to the 20th century AVERAGE TEMPERATURE!

When you've got nothing, throw a stink bomb, the smell lets everyone know you're still here.

"fetid feces face flip flopper fiend" must have a military-sized inventory of stink bombs, since every post he brings into existence, stinks.
