The evidence seems overwhelming. They say that a panel of 25 scientists are 90% confident that GW is to blame on humans. However, we must look between the lines. It is standard in studies to use a 95% confidence interval, this study uses a 90% CI. This shows that this study is not credible. What most likely happened is they used a 95% CI, the data was not statistacally significant, and they did not get their desired outcome. Therefore they could not conclude that global warming is man made. If they decreased the CI, it is then likely they employed other methods such as eliminating unwanted data, or substituting data, in order to get the desired results. It would be OK to use a 90% CI if the results at 95% CI are also published. It is common practice, though, to use only a 95%CI. Also, the panel of scientists were politically appointed, so it is likely they have a political agenda. Global warming may very well be man made, but this study does not concur with that hypothesis.
