Every scientific academy. So all I need to do to prove you wrong is just find one scientific academy. Many of the ones you are of course referring to are governemnt sponsered such as the NAS. Which means that they tend to produce the claims that support those who fund their operations. A great example of what I am referring to was a report titled America's Climate Choices" from the NAS. It was chaired by a nuclear engineer and had 23 people of which only five had degrees related to climate and five were staffers from climate activist organizations. Ninteen of the twenty-three had made public statements supporting the idea that climate change was human induced. Cicerone is only interested in serving his political masters. One of previous heads of the NAS had back in the seventies proclaimed something similar about a global ice age and the NAS dutifully produced to proof for that.<quoted text>
Yeah, that's why every scientific academy on the planet has looked at the evidence and says warming is real, we're responsible, and we need to do something about it.
Maybe you should be asking how accurate has these government sponsered science academies have been in the past. Lets not forget Climate Gate and all those emails that showed that they were cooking the numbers or the IPCC AR4 which now can be found in the fiction section of many libraries.
I can see those selfsame scientific academies with research in thirty years claiming that an ice age is approaching and man is the cause. After all, there are those in politics who are interested in power who are funding them and want something in return. Something that will allow them to increase the amount of power they have and the size of their personal fiefdoms. And there will be people like you claiming that every scientific acaemy agrees with your point of view even when that is not true.
