The contentious "pause" in global warming over the past decade is largely due to unusually strong trade winds in the Pacific ocean that have buried surface heat deep underwater, new research has found.

A joint Australian and US study analysed why the rise in the Earth's global average surface temperature has slowed since 2001, after rapidly increasing from the 1970s.

The research shows that sharply accelerating trade winds in central and eastern areas of the Pacific have driven warm surface water to the ocean's depths, reducing the amount of heat that flows into the atmosphere.

In turn, the lowering of sea surface temperatures in the Pacific triggers further cooling in other regions.

The study, which is published in the journal Nature Climate Change, calculated the net cooling effect on global average surface temperatures as between 0.1C and 0.2C, accounting for much of the hiatus in surface warming. The study's authors said there has been a 0.2C gap between models used to predict warming and actual observed warming since 2001.

The findings should provide fresh certainty about the reasons behind the warming hiatus, which has been claimed by critics of mainstream climate science as evidence that the models are flawed and predictions of rising temperatures have been exaggerated.

"The Tea Party has a right to feel cheated.

When does the Republican Party, put in the majority by the Tea Party, plan to honor its commitment to halt the growth of the Federal monolith and bring the budget back into balance"?
