Global warming is a fact. Some have claimed that every climate catastrophe warning in the past has been catastrophically wrong. Some have told us Don't Look Up because it has rained now that Wimbledon has started.
But average global temperature hit a new high on Monday, only to be beaten on Tuesday. Also, many are not aware that Exxon made ‘breathtakingly’ accurate climate predictions in 1970s and 80s only to publicly dismiss global heating.
Basically, over millions of years, carbon dioxide has been removed from our atmosphere and has been stored in the crust in the form of fossil fuels. The world was a lot hotter and more inhospitable then. Putting that carbon dioxide back in the atmosphere is not a good thing.
