BABY, IT'S COLD OUTSIDE . . . .
It would be interesting to compare some of the 10 yr Forecasts
that the "Experts" in Global Warming came up with say 5 - 10 years
ago, versus the current Very Cold Spell.
I suspect the Average temps in the US for 2019 are going to be somewhat colder than were predicted by many of the "Experts".
Seems quite likely that extraterrestrial effects from the Sun, and maybe even the Moon, were not fully taken into account ( or even totally ignored by some forecasters ? ).
The Sun in particular has significant long cycles of activity which
can have a significant affect on temperatures on planet Earth. In addition, the gradual cooling of the Earth's magma core was not factored in to many forecasts.
Despite being a beach lover, I haven't noticed visible rises in sea
levels at Any of the beaches that I visited over the last year or so .
Indeed locals around the beaches I visit are Very sceptical about sea level forecasts. Some proper checks on Actual sea levels vs Forecasts are overdue.
