So is 400 the critical number said by climate-scientists to represent the "tipping-point", or is it a higher number than that?

Dave Cohen

@Mister Roboto

400 is mostly symbolic. It's the first round number in the count.

Well, I guess I won't be having children, seeing as the future is fucked.

The last time a comparable amount of CO2 was dumped into the atmosphere (by volcanic activity) it was done over many tens of thousands of years and resulted in a temperature increase, of much more than 2 degrees celsius, occurring in a matter of a few years.

We've managed to do what took thousands of years in just 200 years.

Who knows what that will lead to, except that it will not be good for life as we now know it.

It's far too late for talking about now.

Re: the last time a comparable amount of CO2 was dumped into the atmosphere (by volcanic activity) it was done over many tens of thousands of years...

And what event in the paleoclimate record are you referring to?

So. The question is how do you get people to change??

Ben

@Wanooski

This is something I've decided this past year. I wish I could convince others to do the same, but it's impossible.

Dave Cohen

Re: how do you get people to change?

You don't. People must change themselves, undergo a process of personal evolution. Change always comes from within.

They must want to change. First, then, they must realize something about them is not right, that there is a necessity for change. About 0.001 percent of all the human beings who have ever lived have met or currently meet these criteria.

That's the only true answer, and every wisdom tradition on Earth since time immemorial has come up with that same answer.

Quo Vadimus?

Re: Quo Vadimus?

Well, now that I've posted the Remedy du Jour, I was thinking I might walk to the grocery store, and then hit the local bar later.

Alternatively, I could back to Rome to be crucified for a second time :-)

I think you may be just slightly underestimating how quickly and easily Americans can be swayed (or duped) into something. There like a heard of cattle,get one to go toward the cliff and they will all follow. They just need to think it is cool and trendy. Facebook,SUV's?

Human nature plus entropy is not sufficient to explain why history is so full of events. Things do change even if people essentially don't.

I don't like the Great Men theory of history but there it is and it can be used to explain a lot. Then there is the concept of a Revolutionary Moment. Please don't ask how we arrive at one. Though they occur from time to time whether we have any good understanding of their genesis or not.

As regards climate change the dominoes are lined up and have started to fall. Any tiny change that might be made to one vector or another will not change the result. Leadership and policy and all that is now irrelevant.

As per Timothy Garrett, Mauna Loa is the world's most accurate GDP measurement tool.

Over the last year we saw a 1% = (397.17-393.05)/393.05 increase in real wealth.

Average interest on all debt is much higher than 1%.

No wonder everything is creaking and groaning.

Got to burn more shit soon.

It is a lead pipe cinch that humans will burn all the fossil fuels they can, and the cumulative CO2 release will easily exceed the lower bound of the estimate range for CO2 released during the notorious Paleocene–Eocene Thermal Maximum. Mass extinctions guaranteed but not the end of all complex life on Earth by any means. Possibly enough of a population bottleneck to allow a hominid successor species to emerge to replace the epically failed Homo "sapiens". Fukushima type events should help raise the mutation rate. BTW, neither myself nor my brother had children, as we had formed DOTE type views 40 years ago. Best decisions we ever made. Pass the popcorn!
