The is quite a long list of things that contribute to the variability of
climate. One of these is the CO2 concentration in the atmosphere. This
is now about 50% above the pre industrial level. You might not think
that the huge amount of CO2 resulting from human activity in the recent
past has anything to do with this rise or with climate change but the
great majority of the scientists who investigate such matters do.

disease correct?

I'm sure there are plenty of other examples where passionately and
strongly held majority views were eventually shown to be wrong.
