[QUOTE=venom;47677424]why does it fluctuate so much each year more co2 from heating in the winter?[/QUOTE] Seasonal changes. Winter = less plant life due to seasonal plant cycles/shedding leaves, which leads to less CO2 scrubbing from plants. Towards the end of summer, plant life is at a peak and thus more plant-driven CO2 scrubbing.
[QUOTE=Lolkork;47744242]I honestly think we are completely fucked. Most people and companies wont do shit to reduce their co2 emissions if they have to sacrifice something, even if they completely understand the threat of global warming.[/QUOTE] how come china has been reducing co2 emissions then they've dropped 8% in the past year
But this isn't necessarily a bad thing. Without CO2 plants would die. In the near future we may be enslaved by gigantic sentient strawberry plants!
[QUOTE=Deng;47746775]how come china has been reducing co2 emissions then they've dropped 8% in the past year[/QUOTE] china isn't the only economy worth worrying about. as china becomes less relevant to the manufacturing sector and they transition to a service economy, those manufacturing facilities go elsewhere. usually that elsewhere has weaker environmental policy. this is also generally true of any increases in standard of living in any part of developing world, because those increases require energy, which usually entails burning fossil fuels. this isn't to say in some defeatist sense that we're ruined, but we're not out of the rut yet either.
[QUOTE=joes33431;47747050]china isn't the only economy worth worrying about. as china becomes less relevant to the manufacturing sector and they transition to a service economy, those manufacturing facilities go elsewhere.[/QUOTE] Manufacturing is still growing in China however. The fact remains that in the past year they managed to cut carbon emissions, despite no economic downturn. In addition to that, global carbon emissions stopped growing last year (although it still is to be seen if they will grow this year).
it is good that we are making progress, we are achieving "relative decoupling", that is we are reducing the carbon intensity of industry, however, we must achieve "absolubte decoupling" and in fact reduce carbon emissions in total, and it seems like China has just managed that recently. It's such an expensive and huge scale project and one that can only realistically be undertaken by such a strong government like China's. but the situation won't be solved even if we do manage to reduce total carbon emissions, we still need to deal with the CO2 that is already in the air; something that can happen naturally but I don't know how quickly
[QUOTE=TheRealRudy;47677208]yep that's the sign, time to leave this shithole of a planet and colonise the stars[/QUOTE] Too bad the best estimates put that at around 700 years from now. And that's if we don't reduce funding for space travel R&D in the meantime and global GDP stay somewhat stable.
[QUOTE=SpaceGhost;47742950]Hydroelectric dams submerge large areas of land upstream from them, emits quite a bit of methane, and people being displaced. Also the risk of one failing(banqiao dam). Quite a shitty renewable power source, better than coal/oil, but still not good.[/QUOTE] Not to mention they cut off migration paths for fish and stop sediment flow down river destroying coastlines. Hydro is not environmentally friendly by any means. Just because it doesn't have a chimney doesn't mean it's not bad. [editline]18th May 2015[/editline] They also flood/dry up habitats for other things. A damn project in Brazil is going to extinct a few species.
[QUOTE=Propane Addict;47677816]Nuke China and Europe. It's the only way to stop the madness killing our planet. We were here first you selfish pricks.[/QUOTE] You win the Yahoo comment of the year award! Congratulations!

[QUOTE=itisjuly;47744255]If they won't do it willingly we must force it through law. It will end really bad otherwise.[/QUOTE] Or could find a way of unfucking the whole situation profitable. I assure you if they was more money to made to pull the crap from the atmosphere, then putting there, I assure you it get done yesterday.
