By switching from global warming to “climate change” they now blame every weather event on humans, and lack of action by politicians.
This provides a mechanism to blackmail politicians. Any weather event like Hurricane Sandy or a hot summer in Australia is now used to pummel local politicians, few of which have the knowledge or integrity to withstand the pressure.
That is why a knowledge of climate history is so important, and why I have devoted thousands of hours to studying it. Politicians need to be aware of and be able to cite specific weather events from the past, in order to counter the the endless claims of climate change and unprecedented weather.
The world is following the same path of ignorance as in the 16th century, when 30,000 people were burned at the stake for “cooking the weather.”
