You will find guys for every theory, scenario, you can't come later "oh, they knew all along!"
Climate science is about knowing how climate works, but there's nobody out there, legit, that will stand up and say "I know the forecast for every year for the next 30 years and THIS is how you need to invest your monies!" because weather changes all the time and nobody will risk their names, so possible scenarios you shouldn't paint as anything than possibilities, it's so easy to scream later "oh I see snow, im scared! lets spend billions!!!11 and then you get 10 years of drought...but hey..it's only money..in warm region...
