Global warming is an alien plot to make our planet more hospitable for them. The aliens come from a planet that has a higher mean temperature than ours- Earth is too cold for them. It’s too cold now, but they’re making it hotter so they’ll be comfortable and so their alien food crops will grow better. Earth was too cold but it was as close to their planet as they could find, and Earth could be warmed up. Certain people high-placed in various governments are knowingly working for the aliens. They try to stop any attention paid to global warming and want global warming to continue unabated- and if possible be sped up. Al Gore is aware that global warming is an alien plot but doesn’t want to appear even more ridiculous than he already does by publicly saying so. When Earth becomes hot enough, the aliens will show up en masse and move in.
