I'll pay attention when they get a refutation in Nature or similar peer-reviewed magazine. Until then, they're bloggers.
Nature isn't the scientific equivalent of the bible for the religious, in spite of what the Warmist faithful might believe. Much legitimate sounding critique of peer review in the mainstream Science journals has been turning up, concerning the climate arena in particular.
As to whether what bloggers say matters, McIntyre's record is pretty good on exposing bad science without benefit of peer review. His non-peer-reviewed study on Mann's hockey stick graph was able to spark two scientific reviews of the graph, and the general feeling at this time is the HSG has been thoroughly debunked. McIntyre was also able to reveal GISS measurements of US temperatures as faulty, and have the warmest year there changed from 1998 to 1934. Recently the skeptic bloggers exposed faulty data when October 2008 was claimed to be the warmest October in history (it wasn't). The record of what skeptic bloggers are able to do without being allowed into the old boys network of peer review is pretty good.

Here's an interesting one. This is the results of a
CNN poll of 3146 scientists.

Two questions were key: Have mean global temperatures risen compared to pre-1800s levels, and has human activity been a significant factor in changing mean global temperatures?
About 90 percent of the scientists agreed with the first question and 82 percent the second.
The strongest consensus on the causes of global warming came from climatologists who are active in climate research, with 97 percent agreeing humans play a role.
There are of course questions concerning that study from the other side.
Example 1Example 2Basically though it depends on how you frame the questions, and who you ask. Most skeptics agree there was a warming trend, and we are most likely still in it. They also believe human activity which would include stuff like land usage should have at least some influence on climate. There's nothing controversial there if you frame the questions right. You'll get even better results if you ask people, most of who are making a living trying to show the connection between humans and climate.
Other studies give different results.

Professor Dennis Bray of Germany who along with Hans von Storch polled climate scientists to rate the statement, “To what extent do you agree or disagree that climate change is mostly the result of anthropogenic causes?” on a scale of one to seven, seven indicating strong disagreement. They received responses from 530 climate scientists in 27 countries, of whom 44 percent were either neutral or disagreed with the statement (29 percent said that warming is not mostly the result of anthropogenic causes). “These results, i.e. the mean of 3.62, seem to suggest that consensus is not all that strong and only 9.4% of the respondents strongly agree that climate change is mostly the result of anthropogenic causes” (Science Magazine helpfully refused to publish the findings, by the way).
Here's a Canadian oneIn fact it's interesting that the journal which published the study you mentioned
refused a previous study on a similar subject which apparently got different results. The reason given for the refusal of the first paper was " EOS should not accept summaries of opinion polls. and that they wanted to focus on science instead (even in the “Forum” section)". What changed?
