I don't really get the title of this thread. Why call the people behind this campaign "Global Warmers/Climate Changers" if they are attempting to counteract global warming or climate change? It makes no sense.
They are attempting to counteract global warming or climate change by making inane videos? How is that working? It is difficult to keep up with the MMGW (man made global warming) crowd as they have switched the name of their evangelical style belief to climate change.
Given that they used this video, I'd guess it's an attempt at irony. Implying that there is, in fact, tremendous pressure on everyone to reduce their CO2 footprint from the people around them and their own conscience. From the makers' viewpoint, this would be obvious, like saying "We encourage you to do this in order to avoid destroying the planet. But don't worry, no pressure."
Keep guessing.
Like the other attempts at humour in the video, that one probably failed to reach the audience as well.
It would have been much more amusing had they had the global warmer teacher's head explode and show all the hot air escaping.
