Recent study regarding the Sun?

The paper does support the fact that the Sun caused the warming in the Early 20th Century, but not in the late 20th Century. A surprising conclusion is that Rs, which would include not only the effects of the Sun, but of aerosols, including the Asian Brown Cloud, did not cause the recent slowdown in the warming. I await to see if other papers concur with this finding. A new theory which would explain the slowdown also needs to explain the rapid warming since the 1970s.

How much error is there? A slight amount of error in the data (likely or at least not complete data) or a slight difference between theory and reality (very likely) means that the results are meaningless. A very minor difference means that their results don't support Global warming. There will be people who go back and redo this study to show that global warming doesn't exist.

There aren't enough temperature sensors. Of the ones there are (i.e. Fig 1 from the study) many are in urban areas that are likely to have higher temps due to being in an area that absorbs the sunlight. That skews the data. I think the study showed exactly what the they expected it to show because that was how they interpreted their data.

Totally crap research, quote Direct measurements of

Rs cannot be quanti-tatively related to such variability because they have been limited

in their geographical coverage. The approach used here is to

examine a global land dataset of diurnal temperature range(DTR). This concept is not new, indeed, Wild et al. (7) noted

Another **** proxy research paper, not worth the paper it is printed on.

Since you posted the link to it, it is unlikely to be objective, and thus not worth the time it would take to read it.
