Of course scientists' models aren't going to be very accurrate. There are SO many factors and they're NOT factoring them all in. From the sun to methane to volcanic activity to animal farts, I don't have great confidence that "this isn't what the scientists predicted" isn't just the scientists needing to work on their forumas more.
What does it mean to say that X methane wouldn't be released "normally"? Warming releases methane which contributes to warming. Humans have only been pumping out CO2 for barely a few hundred years. Natural warming releases the same methane, which warms and releases more methane. Yet the world didn't heat up and stay hot for these past millions of years--obviously there are more factors keeping things controlled and counteracting warming as well. But everyone who's so sure that they're in the know about EXTREME CLIMATE CHANGE has nothing to offer.
I wasn't questioning your study in what I said about "proposals." I was talking about the impossibility of doing anything about climate change without global cooperation. All of this talk and science is useless in preventing it. Everyone is so eager to self-righteously attack others for not supporting their stop-climate-change tirades, but none of them have any real course of action to do anything about it. National limits on emissions just move production elsewhere where governments do not and will not limit emissions in any way. National limits on emissions do nothing to reduce global emissions, except to increase them through increasing energy costs to transport goods from distant geographic locations.
Nuclear power is the future. Soon we will have completed the development of technology to return radioactive by-products to "I-don't-want-cancer"-friendly states. No one talks about that though. No oil, gas, coal, or alternative "please fund my company" lobbyists are giving big contributions for people supporting cheap, clean energy. All of this nonsense about needing to reduce CO2 emissions by means which do not reduce CO2 emissions will just hurt morons gullible enough to fall for it in the meantime, to the benefit of the fear mongerers pulling the strings to line their pockets and secure their power.
