THE HOCKEY SCHTICK: New paper shows a large increase of solar radiation in Spain since 1985, dwarfs alleged effect of CO2
A paper published today in Global and Planetary Change finds solar radiation at the Earth surface in Spain "shows a significant increase over the 1985-2010 period" of "+3.9 Wm-2 per decade." By way of comparison, the alleged forcing from increased CO2 during the same period was only 0.11 Wm-2 at the Earth surface per decade. The authors attribute the large increase in solar radiation to a "decrease in clouds and/or aerosols." Several other papers have shown a decrease in cloudiness since the 1980's could alone account for all global warming observed since the ice age scare of the 1970's.

2012: The Temperature Standstill Continues | The Global Warming Policy Foundation (GWPF)
To summarise: There is no point in putting out conclusions about the global temperature for any year until all that year’s data is available. It is misleading to only say that the global temperature rise has slowed down since 1980, when the evidence is that it has remained unchanged for the last 15 years...

The 15-year standstill is a real feature in the data.
