It is interesting that the “Consensus” surveys don’t ask the question outright:
Do you believe CO2 will cause catastrophic global warming?
The IPCC doesn’t seem to believe there will be net harm until 3°C.

Watson said there is a 50-50 chance of preventing global average temperatures rising more than 3°C above their level at the start of the industrial age, but a 5°C rise is possible.
Catastrophe means more than a little net harm so let’s define “Catastrophe” as 5°C. An outright global warmer only believes “catastrophic global warming ” is “possible”.

“CO2 will cause catastrophic global warming?”
The Scottish engineering survey was interesting for several reasons.
1. Global Warmers are dishonest and lack integrity (see global warmer response from uknowispeaknonsense.)
2. The “2%” catastrophic response wouldn’t be possible even on a skeptic forum if the “consensus” claims were correct.
3. The 2% is a little low but not as far off as the consensus claim.
Now there is a lot of confusion about what temperatures are used as a baseline and global warmers like to make historic temperatures a moving target because they are not honest and lack integrity. So lets eliminate that and define “catastrophe” as 4°C over current temperatures and “negative” warming as over 2°C above current temperatures.
If someone actually believes the consensus they should survey atmospheric scientists and ask yes/no responses to 4 statements:
1. CO2 will cause 2100 to be 4°C or more warmer than today (2015).
2. CO2 will cause 2100 to be 2°C or more warmer than today (2015).
3. CO2 will cause catastrophic global warming by 2100.
4. CO2 will cause catastrophic global warming.
I don’t expect an honest survey asking the actual questions to ever be made by global warmers. The results would be interesting.
