CO2 Levels Reach 400ppm at Mauna Loa For First Time On Record

Titus Andronicus writes "Today, NOAA reported, 'On May 9, the daily mean concentration of carbon dioxide in the atmosphere of Mauna Loa, Hawaii, surpassed 400 parts per million for the first time since measurements began in 1958.' For comparison, over the last 800,000 years, CO2 has ranged from roughly 180 ppm to 280 ppm. 'For the entire period of human civilization, roughly 8,000 years, the carbon dioxide level was relatively stable near that upper bound. But the burning of fossil fuels has caused a 41 percent increase in the heat-trapping gas since the Industrial Revolution, a mere geological instant, and scientists say the climate is beginning to react, though they expect far larger changes in the future.' The last time Earth had 400 ppm was probably more than 3 megayears ago."

    . It also may indicate negative feedback loops responding to the changes.

    But that's my skepticism in a nutshell. If I light some candles in my apartment it gets gradually warmer, For a while. Then the AC kicks in. The temperature feedback mechanism in my apartment is much larger than the heat source of a candle, or my gaming rig for that matter,

    We know there's some sort of 100 k year cycle. Is it a feedback mechanism? Is it a strong one? Is more CO2 just going to kick in the cooling sooner, or overwhelm the cooling?

    The one thing we do know is that "stable climate" is an oxymoron. Keeping temps at the same level just isn't one of our choices. So is warmer or cooler going to bring a better standard of living in the long run? And is more CO2 going to make it warmer (the simple analysis) or cooler (due to corrective feedback coming sooner)? And if it's going to get bad, what that cost in $, and what's it cost to avoid some of it in $, and what's the cheaper path?

    It amazes my how many people have strong opinions about this, but have never thought about it beyond "man change - man change bad".

    The ones profiting from fucking up the planet are to blame. They have, however, managed to school us into accepting their reality - that we all are in control, individually.

    They've taught us, through millions of 30 second tv-spots and with a little help from collaborators, that their world - the "free" market economy is somehow normal and natural, a basic truth and not an ideology of greed and lying and cold blooded disdain for human weakness while every other ideology, of compassion and sharing, for example, is old-fashioned and silly.

    "'free' market" you write - so you know that it isn't a free market. As to the ones profiting, do you include teachers' unions? If not, why not? They are just one of thousands of groups (whether a union, business, department, politician) that can be blamed.

    Almost half (~40%) of US GDP is spent by the government directly. Of similar magnitude are all the mandated or propped up industries. Regulation compliance, fields with limited competition (doctors/lawyers, anything with government patents or copyright), and mandatory insurance (auto/health) which is really mandatory skimming of the associated costs (I.E., and incredibly dumb fucktarded proposition to force purchase of anything).

    Of course, you mention no specifics beyond "eating the rich" and "fucking shit up". I'm not sure how warmongering is going to decrease CO2? As for attacking the rich, same thing.

    We make good money manufacturing insulation which is used to DRAMATICALLY decrease CO2 consumption. If we become rich off this... is it OK for you to eat us or fuck up our shit?

    As for anarchism, I'm down with it as an anarcho-capitalist (technically also a minarchist/voluntaryist type too - I'm not going to stake a flag in one specific area without better definitions). But I don't advocate murder or fucking people up!!!

    Who mod's this interesting, "eating the rich, fucking shit up"??? I hate to Ayn Randian on you, but I have little doubt that the rich are - in your case - morally superior. You set the bar so low, it would be hard to find worse scum.
