Humans and Nature Duel Over the Next Decade’s Climate
Richard A. Kerr
Rising greenhouse gases are changing global climate, but during the next few decades natural climate variations will have a say as well, so researchers, including a team reporting on page 796 of this week’s issue of Science, are scrambling to factor them in.
Improved Surface Temperature Prediction for the Coming Decade from a Global Climate Model

Previous climate model projections of climate change accounted for external forcing from natural and anthropogenic sources but did not attempt to predict internally generated natural variability. We present a new modeling system that predicts both internal variability and externally forced changes and hence forecasts surface temperature with substantially improved skill throughout a decade, both globally and in many regions. Our system predicts that internal variability will partially offset the anthropogenic global warming signal for the next few years. However, climate will continue to warm, with at least half of the years after 2009 predicted to exceed the warmest year currently on record.

From the BBC website:
The warmest year ‘currently on record’ is 1998, helped by a very strong El Nino.
Hat tip to Bob Carter/Walter Starck for the note alerting us to this insightful analysis by the ‘American Thinker’ entitled Twisting Science to Fit the Global Warming Template.
The global warming crowd does not take kindly to being contradicted, either by critics or data. Of course, critics can be defamed and data can be skewed. But unless the critics can be silenced, they can fight back and expose phony data. When it begins to look like predictions of doom are not turning out sufficiently catastrophic, a full Orwell is called for. The media mobilize their templates to completely re-cast the information.
This process was fully in evidence yesterday when the global news service Reuters spun a report in Science magazine (which has been quietly starting to warn its readership that maybe it would be prudent to come in a bit from the end of the global warming limb) as if it confirmed the seriousness of global warning, when in fact the report contained devastating information of flaws in the doomsters methodology and warned that the disaster has been postponed………..
