No need to be sorry, here you go an article from a reputable source citing a study from european researchers - https://www.dailymail.co.uk/sciencetech/article-8555871/Mediterranean-Sea-3-6-F-hotter-Roman-Empire-study-claims.html

Cant write much atm, so let me just address the “who makes the money” for the time being. Co2 credits are traded on stock exchanges, london has imposed a daily tax on older cars(affecting poorer citizens), developing countries are being hindered as clean energy is not yet an affordable alternative and by this western countries which already went through that process(and it was ok when the west was doing it) effectively destroying existing and potential competition. Its basically making the game unwinnable for them by changing the rules all the time.

Just few quick examples that come to mind how it is lucrative, not to mention the psychologicall effects that fearmongering has on the younger generations living in a state of impending doom all the time.

Its cycles, and it depends when you start the measurements from. If you start measuring 38 years ago, then there is no change in temperature. If you start in 1850 then were warmer by 0.7C. From middle ages, were colder by 4C. From the times of the Vikings we have warming, and from times of Jesus we have cooling down. Cycles. Money also has cycles. In the past (i know of examples in the 70s) money was made on the fear of The New Ice Age, and today its the fear of Global Warming.
