Okay, for sake of argument I'll accept the idea that it's manmade. I still completely oppose a carbon tax. I will fight any attempts to ban or create punative taxes on any type of vehicles or products. I think tax subsidies to renewable production and most research are completely wasteful. And finally I believe that economic growth is a far better solution for addressing the climate change problem than any CO2 reduction idea proposed by the left.
So you're saying you don't support a 200% reduction in CO2 emissions? (100% to get to 0 then another 100% to capture the stuff we've already released, which is a lot)
Someone on a previous page said we would just need to stop CO2 emissions and the ocean would soak up the extra CO2. This is wrong. The amount of gas held by a body of water strongly depends on temperature. Since we've already started the warming process, and the warmer ocean is now
releasing CO2. This makes the warming happen even faster, releasing even more CO2. It gets worse when we factor in all of the CO2 and methane gas that were trapped in or under the ice covering the poles. Siberia is releasing huge amounts of methane into the atmosphere as the permafrost melts. This speeds up the heating process, melting even more ice, releasing even more methane and CO2. There are a lot of positive feedback loops in effect. This is why our climate records often show sudden exponential changes in temperature or atmospheric composition. Once the ball gets rolling, it goes faster and faster.
We're pretty much past the point of no return. You can ask any scientist about Greenland, and they'll tell you Greenland will melt regardless of what we do. The only thing we control right now is how fast it melts. Instead of trying to stop this avalanche of positive feedback loops, our resources would be better spent preparing for what happens next. Some areas will get dry. We should improve our irrigation systems; I'm thinking of Texas in particular right now. Some areas will see increased rain and snowfall, so we should keep that in mind when building new infrastructure.
If we really want to help people in poor countries, we should try giving them jobs. If shitty African countries had developed economies, they could afford to do things like irrigation and water treatment. It would also reduce the reliance on regional food production. If you are trading with the entire world, it doesn't really matter if your particular area has a bad grow season.
