But peak oil - I dont know. Looking at this chart - at least production seems to have reached a plateau snce about 2004, some slight increase is predicted by the IEA if all kinds of unconventional oil will be used. The environmental impact is rising sharply and the EROEI is dropping as sharply. I think these are clear signs that we are "scraping the bottom of the barrel". Of course there will be oil in the future. The statement that "oil will run out" is nonsense. The problem is not that one day there will not be oil when the day before it was there. It is that the production cannot be increased and eventually decreases while prices shoot up, only stopped by a severe economic crisis. And more on topic with climate change - people were predicting climate change within 2-3 decades about 2-3 decades ago. And what happened? Nothing? We are still alive? That was not what they said back then. What they said was that climage is changing and global surface temperatures would rise. And they did. And now it is more than half a degree centigrade warmer than in the 1970ies. The alarmists of their time were right - just that we dont all sweat in winter by now does not mean that there is no problem. Climate change wont work that way. But still - even personal experience begins to show it. This year, trees around southern Germany started to go in bloom again in Oktober instead of around March/April next year. They started to get leafs and buds, just to be killed by frost. Of course its anecdotal (Probably happened before in history) but the hard science supports that the change is here. These predictions about 5 years is also not that in 5 years the world will turn into a hothouse and deserts will be in the UK - but a certain threshold will be passed that has a meaning - that after that date, it will require massive efforts and uneconomic actions (like shutting down newly built coal plants - what company would do that voluntarily?) to save the greenland ice shield from melting.

And even if the atmosphere as a whole cools - the part we have to be concerned about is surface temperature because this is where the ice and the biota are. |
I always thought oil had at least 100 more years before running out :hmm:

Word on the street is also that coal will take way the **** longer to run out, which concerns me greatly since coal has to be scraped up :(

Coincidentally, new emails of IPCC have just been released. (Read it yesterday in the BBC website, but BBC is unavailable at the moment of writing this).
Confidence is something that cannot be restored after it has been broken. Remember when a certain group of scientists alarmingly warned the world saying that the Himalayas were going dry in 30 years time? After a simple calculation, they were proven wrong and they finally admitted they did it on a political basis. The whole debate about what is really happening to the global climate could have been over a long time ago if the data and methods used by the IPCC were openly released for revision. |

And re this article - it is from the freaking IEA - a bunch of guys who always used to tell us that there is no problem in the next few years. Quote:
I dont think NIMBY is a problem so much. Actually people next to nuclear power plants do not always mind it - in some cases they are well paid. But the impact of it ranges farther. Honestly I think those who profit from something should also have to live with the impact. If someone wants nuclear power, they should not mind living next to a nuclear plant and nuclear waste storage. If someone wants solar or wind, they should not mind those contraptions built next to where they live. There is no clean and no-impact source of energy. And if one actually experiecnces the impact of it oneself, one may be much less inclined to waste energy or to create stuff that uses even more energy. This is only too easy if one can drop the trash on someone elses land or on everyone elses land. Quote:
If they make it - good for them. I will accept new situations when they arise, but I would not bet the world on it. Basically there are 2 possibilities we face if we change the way we use and produce energy now - a) DEMO will work in 20 years and fusion poower will happen on a large scale in 40-50 years, then we have invested some money in energy sources that have become obsolete by then - after a lifetime of 40-50 years and have produced cleaner energy in that time - people have learned to value energy more and consume less. Not a big loss I'd say. Or fusion does not work in that timeframe but takes 60, 80, 100 years or never works as cleanly and safe as hoped for - then at least we already made some good steps. I think nothing can be lost by acting now under the assumption that fusion will not come in time. |

Reactions can today be contained, and work is on improving the necessary conditions and energy return. I agree that it would be extremely stupid to go 'well, things SHOULD be able to be replaced in 20-30 years so we shouldn't renew infrastructure now', as a lack of renewal would price consumers out of the market entirely unless governments are forced to regulate, and perhaps even directly set energy prices. Decommissioning some now-obsolete infrastructure before the end of its lifetime is a small cost in comparison. On the other hand, remember that advancement is exponential. It took humans millennia to go from bashing rocks together to working simple metals, or hundreds of years to go from hot air balloons to aeroplanes, then only 44 years to break the sound barrier, then merely another 22 years to humans walking on the moon, while today, the number of transistors on a chip regularly doubles by the year. The vast majority of classic scifi underestimates progress when showing or referencing events that are now in the past, and indeed, the perception that something should be doable is an extreme drive towards its actual accomplishment. |
No one is "squeaky clean". No one. Not the IPCC, not the politicians and not science in general. About 5% of all scientific studies have falsified or badly interpreted data or did not follow proper scientific methods. But that is just 5% - it still means that 95% are good and at the number of studies speaking in favour for human made climate change even if 5% of those would be bogous, it still is vastly convincing.

But mind one thing - the purpose of good SciFi is not only to inspire people about future possibilities but also to warn about possible future consequences, present day problems and their projection in the future... |

If technological development was independent from everything in our society, then one could argue with such examples, but as it stands, the progress of technology is always tied to its financial implications. |
Yes thats true - social, financial and franky resource limitations are reasons to slow down "development". Which is why I dont think exponential growth in technology is not possible in all branches of it.
Especially with the law of diminishing returns in place. The only reason why technology grows fast and in some cases even exponentially is because at the same time exponentially more resources are put into it (human, natural, mineral, informational, computational). In computer technology it is a bit of a special case because in this case, at least one of the resources required (computational power) is generated by the process itself, which is why it can be exponentially growing. Processes usually only grow exponentially if they are having some feedback loop in which this happens - in which the output feeds into the growth again. Other technologies that do not have this characteristic are dragged along by computer technologies growth. Still the other resources are not growing in the same way, minearl, human and natural resources as well as energy is not able to keep up with the increasing demand of this exponentially growing technology on such a wide and large scale. |

As for the rest, that's exactly how it is, because developing better computers allows the development of even better computers and so on, not to mention the benefits that come with increased computational potential. Developing cheap renewable energy sources is against such ideal, because once you get such system in place, there is no reason to invest in it anymore, and thus developing it would stop altogether. Everything in our financial system is based on the impossibility of endless growth, and as you mentioned, while there are some branches of technology where such paradigm can work to a degree, it's impossible to achieve any sort of sustainability in our current model. Suffice to say that if the advancement of technology cannot be used to make more money than it consumes, then such development rarely, if at all, happens. |
You know what the funny thing is, in Germany they decided to go down with nuclear reactors, and now they got PLUS OF 20% CO2-Emmissions in 2011.
