Sorry, but it’s your reading comprehension which needs work. The Australian engineers could have easily said “We are confident that increased levels of CO2 in the atmosphere will lead to amplified warming, which will have significant negative effects on humankind.” However, they chose not to do so.
From your quote, it’s possible that the Australian Engineers believe that CO2 emissions will not cause warming but will instead cause a new ice age. It’s also possible that the Australian Engineers believe that CO2 emissions have a one in a million chance of causing modest negative consequences, but still think it’s worth reducing CO2 emissions to reduce that risk. It’s possible that they believe that CO2 carries no risk at all and that it’s other emissions which pose risk, but they support the Kyoto Protocol because it will benefit Australia in some way.
All of these interpretations are consistent with your quote and none of them means an acceptance of the CAGW hypothesis.
If these “scientific organizations” really want people to believe that they have accepted the CAGW hypothesis, they could easily say so explicitly. Instead, they use ambiguous language. Thus allowing alarmists to jump up and down screaming “consensus!” (whatever that means) without actually putting their credibility on the line.
We aren’t talking about AGCC. We’re talking about CAGW. They are two very different things. Although many alarmists like to blur the distinction.
Then ask me about the words I actually used, instead of the words you wish I had used.
