This ought to "shut up" climate skeptics: Earth warming so incredibly quickly that allegedly only one-third of sites have cooled over the last 70 years

According to the Berkley’s project leading scientist, Robert Rhode, urban heat does not contribute significantly to the average land temperature rise, because urban regions amount to less than 1% of the land area.

Indeed, two-thirds of the weather stations reported warming of land temperatures over the last 70 years, while only one-third of sites, the bulk of them in Europe and the United States, reported cooling temperatures.

“The large number of sites reporting cooling might help explain some of the skepticism of global warming,” Rhode said, adding that it is very hard to measure weather consistently over decades and the presence of sites reporting cooling temperatures can false data. This is why it takes hundreds of stations to detect and measure an average warming, work that was done by the California University scientists.
