In the UK I would be "a criminal". I wrote some scientific reports on the climate. Like this one

The effect of CO2 on climate is minimal, based on Physics. In practice it is neglectable. And in the past CO2-concentration has been much higher. ALL other effects are completely ignored.

But to create the idea of a global catastrophe, the agencies have been using statistical trickery to pretend that the climate is rising.
We see trickery and propaganda in every climate scare agency.

A famous one is using the correlation between CO2 and climate in ancient history. This correlation is caused by the CO2 being released from the oceans during hot weather (similar to how CO2 is released from warm soda or beer).
They don't tell you that vikings were harvesting hop on Greenland.

Another correlation is the usage of old measuring stations inside cities. Cities have been growing and they create a warmer local climate. This can make the local weatherman think that there is a global warming. To exaggerate this trend, the agencies have also altered or removed the existing data from stations outside cities.
And to make the trend last over many years, certain people inside the agencies have been altering the old temperature data downwards.

The politicians and the news papers have also overhyped the climate. Whenever a local weather event occurs, it is blamed on global warming. Tony Heller on real climate science has done a lot of small videos about this subject.
