So, even with the recently decreased solar input [solar cycle 24 is about a year late in arriving, currently there is _one_ solar cycle 23 sunspot, after a couple of spotless months] average temps will climb as concentrated earlier input is distributed through the rest of the system. |
The GMT has not climbed since 2005.

Those who still believe in AGW have to be able to show that any CO2 driver is powerful enough to seriously disrupt the solar driver. If all that the CO2 does is to marginally raise global temperature over the period of a natural solar driven warming and cooling cycle then there is nothing to fear because the mitigating effect in cool periods will outweigh any discomfort from the aggravating effect at and around the peak of the warm periods.

I hope this is true but it runs counter to the observed temperatures and solar irradiance over the last 20 years or so, even if you consider thermal inertia which I doubt could last that long.
