Truth_Quark's Journal: Infilling of the HadCRU temperature data.

Researchers (with an interest in climate science communication) have produced a temperature data set that includes the sophisticated (compared to NASA) sea surface temperatures, but with estimated global coverage (As NASA does, but HadCRU doesn't).

The result is a greater warming since 1997 than has been previously estimated.

Global warming since 1997 more than twice as fast as previously estimated, new study shows

The paper is titled "Coverage bias in the HadCRUT4 temperature series and its impact on recent temperature trends". (Abstract only)
