The hoax is that they try to imply that ANY change in climate is due to man's activities. Data across a wide range do not support the theory that man's activities are changing climate, but that doesn't stop them from promoting the "climate crisis". What bothers me is that even so-called conservative talking heads don't bother to learn the science, and instead, just harp on the "government shouldn't require this or that" argument, rather than "data do not support man-made climate change".
