Will AGW have effects? Yes! Has there been temperature rise over the past 150 years and will it continue for some time to come? Yes!

Will the ongoing melt, which commenced at the onset of the current interglacial, continue apace until the end of the interglacial? Absolutely!

These are scientific facts.

What a lot of folk don't get is that the combined forcing factors of greenhouse gas and melting the polar ice caps are together much larger than the forcing factors of the Milankovitch cycles.  Ice ages only come and go when the climate is in a certain temperature range.  Melting the ice caps takes the planet out of that range, and Milankovitch becomes irrelevant.  Ice ages should be associated with the polar ice caps much more than they have been.  Right now, the Arctic is going, and historically whenever the Arctic goes, the Antarctic follows.

That's part of the 2 degree goal, protecting the ice caps.  If we don't do that, game over.  Interglacials won't necessarily exist or end in the Anthropocene.  We'll have an entirely different set of default climate states.

On a personal level, I figure I don't have to worry too much as I'm too old to be around when things really start coming down.  However, I've long suggested that the next generation of prophets might be labeled Generation Green.  By the time they come into full voice, climate change will be beyond denying, and they will be ticked of at earlier generations who messed up their planet.  Major policy changes seem very likely.  Any politician standing in the way of such changes is apt to get subdued with prejudice.

It's been a while since the 1960s.  The return of the prophets?
