See that 5 degrees Celsius we're projected to hit by 2050? That's 9 degrees Fahrenheit. That means the end of human civilization, and possibly of the human race itself. Within our lifetimes.

Your brain will fight it, even with the numbers on the page staring back at you, because the collapse of civilization is simply beyond human comprehension. To really internalize this information means you would need to accept things like:
- You are among the last people that will ever walk the Earth
- Your children wont survive to middle age
- All of the beauty, culture, and scientific discoveries weve unlocked will return to the ether from whence they came.
Forgive my French, but that is some heavy shit. Yet our ability to understand and feel threatened by this information is hindered by the fact that things dont seem that bad right now. Sure things feel a little off, but how can we be so close to oblivion when life is (generally speaking) so good, modern and happy?
The answer is exponentials. Climate change does not follow a linear path (1, 2, 3, 4, 5, etc ), it follow an exponential path (1, 2, 4, 8, 16, etc ). Global temperature is increasing exponentially, fueled by humanitys exponential rise in energy use, population, and economic growth. As you can see from the chart, exponential functions look like a hockey stick: they stay low for a long time, and then rise very suddenly and rapidly once they turn the corner. Everyone has some experience with exponential growth in their daily lives any bank account with compounded interest will follow this curve, and exponentials are the reason that sickness spreads so rapidly through your childs school.

(25,966 posts)Our emissions will be fixed for us, via collapse. The real question is, will collapse happen soon enough to prevent change that even humans won't survive.

(1,941 posts)This is not a human extinction event, this is the end of the world as we know it.
Hype just gives idiots something to carp about like with nuclear winter. Could we end all life on earth with nukes? Of course not. Could we blast ourselves back to the Stone Age? Absolutely. And even a partial exchange would make WWII on the eastern front look idylic. Even blasting ourselves back to the 19th century would be horrible beyond contemplation. But if you overblow some of it idiots will assume you are overblowing all of it.
I think the collapse of civilization from the equator to temporate zones would be pretty goddamn awful. Certainly it will be the end of western standards of living for most of the west.
You know why it won't be fixed? The people in charge will be dead by then. They don't give a fuck.

(60,010 posts)We have blown thru every single date projection of climate numbers already..
a steady stream of headlines over the last few years has announced new levels of climate change indicators
"years before predicted".
We R screwn. Much much sooner than originally thought.
Ages from now, if any humans are left, they will be wondering "how could they have been so stupid?"
much as we shake our heads in amazement at the stupid events of history in our past.

(11,087 posts)If they have to choose between saving your life and making that penny of extra profit, well, I hope you have your will drawn up. If that penny of profit this quarter results in the collapse of human civilization 50 years from now, well, . . . IT'S PROFIT!
The only argument they will listen to is "You can make even more profit later." Yet, in a choice between profit now and 100 times the profits 50 years from now, they may well choose "profit now." The 60-year-olds in the corporate boardrooms don't look much beyond 5 years in their planning.

(10,745 posts)First of all, with maybe one or two exceptions(Hansen & Lovelock might be the only ones), no climate scientist worth his or her salt has ever predicted the supposedly possible extinction of the human race or "inevitable" end of human civilization though AGW alone under even the most pessimistic scenarios.
Also, while most of the temperature graph you've posted looks decently done, there's one glaring flaw: that pink line. There is no plausible prediction out there that has us going beyond 6-7*C by 2100, and that's with all feedbacks at their absolute worst extent. Period. And the pink line suggests we'll be hitting 5*C by 2050.....which is simply not possible under these circumstances, as we'd had to have burned more fossil fuels than are available on Earth, and frankly, we'd certainly have had to see methane releases far earlier as well.
Things are already bad enough as is, kpete. The last thing we need now is "Chicken Little" bullshit being distributed as if it were factual(shame on you, Science Pope!); how in the hell are most people going to want to wake up, if everything they hear from our side is how we're inevitably doomed to extinction or that civilization will surely collapse, etc.?
No wonder why we're having trouble making progress..........

(54,014 posts)The problem with that being the calendar keeps progressing after that date, as do the climate-warming processes, like the defrosting of Siberia, the disappearance of the Antarctic ice cap, and the desertification of the Amazon and Congo Basins. Ending of greenhouse emissions won't reverse those self-sustaining processes. If we flat out ended all global emissions today, the Arctic ice cap would still disappear over the century. There's still no science in on where and how these processes will find a plateau and stop making things hotter year after year.

(10,745 posts)Yes, it can be said with certainly that climate change has indeed presented us with many challenges, some potentially serious, unfortunately, and that we do need to ramp up the action on combatting climate change ASAP.....however, though, it also seems there's been a huge explosion in extreme, implausible predictions, and hardcore pessimism ("we can't stop it!" "It's too late!" , and dare I say, even a little bit of fearmongering(If you've been around long enough, you may remember a piece by the "Arctic Methane Emergency Group" written by one Malcolm Light who insisted that humanity would be extinct by mid-century. Do realize, by the way, that no climate scientist worth his salt, with only a very select few exceptions, has ever made this kind of claim.). As I and others have said many times before, this kind of thing simply is NOT constructive and in fact, is turning people off.
Again, thanks.

Even if this is all true, it would just delay the inevitible.
I say we create a nuclear winter to offset the greenhouse effect.

(275 posts)as I've been reduced to repeating news from untrustworthy sources..bam! lol
It is very sad. Even in my early teens it was quite apparent that we are headed towards destruction one way or another. Even if it isn't full destruction and a handful survives and manages to rebuild, that group will lead us to destruction. Without humanities self-awareness the planet had managed to build itself a nice stable eco-system where everything lived and died according to surroundings without overly destroying things. Yes, sometimes some animals or organisms managed to do some damage but such damage heals in the blink of an eye. The damage we are creating is in some ways irreversible and over time WILL be completely destructive.
When you look at things in that light, it is really hard to get excited about much isn't it? @#$#$@, my team didn't make the playoffs. Oh well, humanity won't be there to care in 100 years.

(10,745 posts)TBH, this idea of a possible Ice Age coming after AGW doesn't seem all that likely to me at this moment, TBH.....but, and this is a big BUT.....I don't think it can be really ruled out, either. We don't know for sure how else the atmosphere may react in the future, particularly once the ice caps start disappearing, with possibly the only really obvious exception being that we're not going to see "runaway" warming as some have erroneously claimed in the past.
Thanks for posting this video, btw, and in fact, I may even repost it to the V & M section of the site.

(1,269 posts)A little energy (coal for electricity in Ohio) co-op mag gets published 1/mos, Country Living, & the pres & ceo, Anthony Ahern, comments on something written by the editors of MIT Technology Review in the Feb issue. The gentlemen at MIT have argued that the president must address CO2 emissions, that renewables are not ready to compete with fossils, that "immediate spending and economic sacrifice by present-day voters" must be advocated by Obama, and that these emissions must begin to decline by 2017 or it will be too late.
Our good coal man Ahern, the head of the co-op replies that all we can do about the problem is R&D. But it gets better, "... the plea for elevating climate change to the pinnacle of societal issues suggests blindness to the human condition. The editors (MIT) put little value on how hundreds of millions of people were lifted out of poverty through the past use of fossil fuels, and the additional millions of people worldwide who will see their quality of life change, thanks to the availability of reliable and affordable energy from coal, oil and natural gas."
In other words, there is no problem. We will just keep doing this because in the past it's lifted people out of poverty.
The cream of the country brain crop - deep do do. I already wrote these dicks once when they ran a nasty Hillary joke. Told them I had some Dubya humor on hand if they wanted to print it. They didn't respond.
So I wrote Mr. Ahern, and told him he was quite possibly not as bright as the souls over at MIT, in nice language.
Just unbelievable. Quit being so blind to the human condition just would ya?

It was written in the Bible Revelations no? All of the Believers will be swept up to heaven. The heathen liberals such as on DU will be sent to Hell.
This is the unfortunate attitiude of tens of millions of RW Christians who actually look forward to the Rapture. With them as Republicon voters I dont think we have a chance to change anything.

(4,835 posts)Y2K was going to kill us all, then the Mayan prediction (which they never really predicted), now we have this. I have a secondary degree in environmental sciences; so I'm familiar with the concerns, but I don't think there's any benefit in being hysterical about this.
This looks like full blown hysteria to me. Yes, we have some very difficult decisions to make, and we need to be dealing with them now, but this whole Siberian methane gas thing - continuing even after we start reducing CO2 emmisions; let's just say I'm skeptical.
The problem with the way things are right now is that we have a positive feedback loop. The more CO2 we put in the atmosphere, the more greenhouse gasses we put in the atmosphere, the more global warming we have - on and on.
CO2 is heavier than air and is necessary in plant growth. Once we begin to reduce CO2 emissions; we will begin to reduce CO2 in the atmosphere. If we are really getting close to peak oil; that will happen, whether we take any action at all.
My point, though, is this: when you create a graph and a doomsday scenario with dates and predictions; the first point on that graph that does not coincide with the actual data for that date, trivializes the entire issue (now we're back to Y2K).
I'm aware that the greenhouse gas buildup in the atmosphere is a huge issue (I've been hearing about it since I was in high school in the 70's). I think you're helping the issue about as much as the people who were trying to make a case in the late 90's that we were getting too dependant on computers.
It's a huge issue and good solid scientific evidence is available; let's not resort to hysteria.
