Sunspots still zero... forecast cold?
The 15th of April 2010 was cooler than the same day of April in 2005. Does this mean global warming is over?:

Solar activity has sputtered again, the 11th day in a row without a sunspot even though we should be spiking up in activity:
Does this mean it's still sunspots zero... forecast cold?

That short term drops in sunspots have any thing but a small effect has never been disputed, except by deniers and their pet blogs.
During the low between cycles 23 and 24 deniers kept trying to reference the LIA and draw the connection, the Solar shut down during the LIA was 50 years not 2 and we have no idea what other activity was happening on the Sun during the LIA.
We do, on the other hand, have a far more recent shut down in the sunspot cycle and we have a temperature records to match against it from 1913.

And the temperature record

With no cooling around 1913 in fact not till around 1940.

You have to wonder how long Peter and co can keep up this 'sunspots zero forecast cold' nonsense. We've been at or near a solar cycle minimum for about 5 years now.

Yet April 2009–March 2010 was the hottest 12-month period on record.

They seem to be operating under the principle that 'if I keep making the same prediction, as long as I don't specify when it's going to happen, it will eventually happen, then I can say I was right'. Or better yet, they can just wait until cycle 24 starts up and say "temperatures are high because there are sunspots now!". It's just a waiting game.
Physics and reality have debunked this particular forecast. Longest solar cycle minimum in a century combined with hottest global temperatures in thousands of years? Sunspots still zero - forecast still really darn hot.

No - one day's temperature reading doesn't prove anything one way or another.
Lack of sunspots, all else being the same should lead to a period of cooling, so I'm picking that you are right.

Sunspots are still at a minimum... the forecast is still for cold.

I think El Nino will last longer than anticipated and that this will be a hot Summer in the US. I think that natural gas is way underpriced and would buy stock in domestic drillers such as NBR.

I don't think it's quite that simple. But Science journal predicts pretty much that for Northern Europe at least http://news.sciencemag.org/sciencenow/2010/04/calm...
