good for them...so called climate change is a naturally occurring event in my mind...if you can even call it an event.
I don't know what the big worry is when we can't even acknowledge the damage done by nuclear power plants like the Fukishima and Chernoble disasters.
Nuclear power plants leave much more to be concerned about (in my opinion) as the devastation from them is truly horrific, and still happening now, and probably will continue.

Those were minor events compared to what humans are doing to the planet....Global warming has heated the oceans by the equivalent of one atomic bomb explosion per second for the past 150 years, according to analysis of new research.
It's a big planet and has been heated to much higher temperature ranges before. Once we humans die out, the planet's biosphere will gradually return to normal after a few thousand years and new life forms will start evolve. Who knows, a new species of sapient creatures may even arise, then wonder about us and learn new lessons.

Over in Alaska the remains of forests are still being found under areas that have been covered by ice for thousands of years, so I imagine that these parts of the world have been quite warm in the past.

When you boil water, do you put the pan over the flame?...Or under it?

Good post...But what's "normal?"

Point well taken...However: as Alpine glaciers have receded in recent years, long dead tree stumps dated to the Roman Warm Period have been exposed. Those trees didn't germinate under the glaciers.
Odd, but Julius Caesar didn't mention glaciers in his Commentaries, although he had to cross the Alps with his troops several times and he was quite explicit & complete about describing the natural history & various natural phenomena he encountered on his exploits north of Italy....And Europe hasn't wandered a whole lot in the last 2000 yrs...
..Two and a half centuries before Caesar, Hannibal lost most of his troops and almost all of his elephants in the bitter cold & snow trying to cross those same Alps.
Weather & climate are naturally cyclic. We're not seeing anything we haven't seen before-- many times.

Not quite. Yes, climate change is normal. What's different is the rate of change. Rapid change introduces environmental stressors that can disrupt the ecosystem and lead to mass extinctions. The biggest danger is that we reach an ecological tipping point, such as from a mass release of methane from the arctic tundra. That's why I think we should be investigating ideas like geoengineering techniques for removal of extreme methane excess.
A mass release of methane from the Arctic may come a lot sooner than there is time for to come up with geoengineering techniques to remove it before it happens. The book's author, David Wallace-Wells, says the earth is at 1.1, but northern Canada has already surpassed that, it's increase is now at 2.3.
Canada is warming twice as fast as the rest of the world according to the latest scientific report from Environment and Climate Change Canada:
" ..... Canada's annual average temperature has warmed by an estimated 1.7C (3F) since 1948, when nationwide temperatures were first recorded.
The largest temperature increases have been seen in the North, the Prairies, and in northern British Columbia.
Annual average temperature in northern Canada increased by approximately 2.3C. ...... "
