Do they think we are stupid?

I just read a humorous article on global warming. The only problem is that it was supposed to be serious. According to some scientists, America is set to experience colder temperatures over the next decade due to ocean currents. But they warn us not to let this dissuade us from believing in global warming. Just how stupid do they think the public is? I am not a scientist but I can see through the tired propaganda of the global warming community. Their logic is if it gets warmer it's global warming and if it gets colder it's still global warming. Give me a break. Finally, by admitting that water currents effect temperature they undercut their arguments that so called "climate change" is determined by human activity.
