And even then, it seems that the real kicker might have been the melting of frozen methane on the sea floor. Which melted due to the raised temperatures caused by the release of CO2. Plus some nonsense about the formation of the supercontinent Pangaea and poor deep ocean circulatory systems and loss of shallow seas and boom! mass extinction to end all mass extinctions. So in short, additional CO2 bad. Anthropogenic CO2 emissions will bite us in the ass. |

During my time in university I had the opportunity to take some classes with an atmospheric scientist who had served on multiple international groups devoted to climate change such as the IPCC. His outlook was decidedly negative, but he was not a doomsday theorist. He fully believed that global society has the tools necessary to combat it, and that given the right preconditions it would be possible to launch a massive effort to help reverse it. He was worried that we will soon reach the point of no return however.
He also discussed some partially classified work he did with the Pentagon as part of climate change disaster planning. The gist is that even if the world government's do not come together to address the actual issue of overproduction of CO2 that someone will geoengineer a very crude "solution". This could be as simple as merely shooting sulfur-type stuff into the atmosphere using capital ships (he estimated the cost at around $30-50 billion a year, easily done by any country with the requisite naval capabilities) or as complex as shooting nano-machine type materials into the upper atmosphere near space that would reflect sunlight before it had a chance to enter. The idea is that we can't stop the physical dynamics of the greenhouse system once sunlight enters, so if we stop enough sunlight from entering at all, that could balance it out and stop potential temperature increases. None of this would fix problems with CO2 concentration itself though, like ocean acidification. ED: Oh yeah, he was def. more worried about methane from the arctic than anything else as having the potential to truly end it.

There's no doubt we're using natural resources to a point it will become unviable, and CO2 level are ridiculously high. But I think nothing really alarming will happen in the next few decades.
But the next hundred years or so will be very interesting, might be a time of hard decisions for mankind. |

To everyone that says "fuck it i'll be dead by then anyways" consider this:
What IF, after death there is no "afterlife" and no eternal nothingness but you are simply being REBORN, a new mind in some new body with no recollection of what was before! Very plausible as far as i am concerned, and you will STILL be stuck with the same problem then, only it got worse cos you didn't do anything about it previously :( I say we need to get on to fixing this before the shit hits the fan! |

Of all the things in this life to worry about, ain't wasting my time on something I can't fix.

Well I believe the Earth was much warmer a couple of thousand years ago and the Earth's climate fluctuated quite a bit in the last hundreds of years (before the Industrial revolution). I am also not convinced that the temperature will just keep on climbing in the future. So I think we'll be fine. The biggest problem will be to deal with the economic impact that a large change in climate will cause. It could destroy complete industries in certain countries yet produce new ones in others.

yeah, we're fucked while we remain carbon positive (adding carbon to the atmosphere) or even carbon neutral (we produce no carbon).
but there's still hope. we need to become carbon negative. how? we use our carbon neutral energy sources for not only powering our energy needs, but also sucking carbon out of the air and literally storing it as blocks of carbon (maybe even use the carbon for building materials or something). what i like about that idea is that we are starting to proactively terraform our planet to suit our needs. anything less than that... yeah, we're done as a species. |
