John is lying, he knows perfectly well that there have been several studies and surveys of the consensus, as I pointed out to him repeatedly back in May. And he also knows that the consensus is for “most” warming, not “some” warming being caused by humans, because I pointed that out repeatedly as well. And it’s a hell of a lot more than 68 scientists, in fact there are thousands of scientists publishing thousands of papers in the field of climate science, most of which were reviewed in the Cook 2013 study that looked at about 12,000 papers. See my big article for details:

Second, the question asked was: does co2 have an effect on the environment. Yes it has. I agree. Limited but some.

In a Pew survey, 77% of “domain experts who are Earth scientists” say it is “a very serious problem” and another 17% say it is “somewhat serious”. Another study found that “41% of scientists believe global climate change will pose a very great danger to the earth in the next 50 to 100 years, compared to 13% who see relatively little danger. Another 44% rate climate change as moderately dangerous.”

They didn’t ask : do you beleive we will have 1400ppm of co2 in 2100 and that temps will rise 3.5C and that there will be incredible damage

As I said to John earlier:

Climatologists do not predict “huge” CO2 emissions. There still a business-as-usual scenario in IPCC reports (RCP8.5) to remind us to change our ways, but there is also a best-case scenario with low emissions (RCP2.6).
Climatologists and the IPCC don’t predict which scenario will happen, or that any of them will happen. Predicting human behavior is not in their job description, although they do rely on estimates of the range of possible human behaviors because climate predictions are conditional on human behavior.
The scenarios are merely examples of what might happen. They are not conclusions, and they are not predictions.
I doubt climatologists thought that the best or worst case was very likely. “In between” scenarios like RCP6 and RCP4.5 are more likely — although solar technology is advancing faster than anyone expected, so maybe RCP2.6 is within reach after all.
One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
