The impedance of IR is logarithmic rather than linear, meaning the effect of the first 20 ppm above the industrial level of 280 ppm is greater than the rise from there. Additionally the density of the atmosphere and the gravity field of the planetary body has much more to do with the median temp of lower tropospheric temps than atmospheric content. Just look at Venus and Mars for confirmation of this. Both bodies have a 97% atmospheric Co2 content, but the atmosphere of Venus is orders of magnitude denser than Mars, or Earth for that matter. The gravity field of Venus is 3 times stronger. You might ascribe the temp difference due to solar isolation differences, but that is clearly not nearly enough of an effect to account for the 1000 degree difference.

As far as human co2 emissions; they amount to less than 4% versus 96% natural. The residence time of either type of emission is 5-7 years- meaning the hundreds or thousands of years for sink uptake claimed by some wack job climate scientists is BS.

In recent years the recognized ECS of a doubling of CO2 has been steadily declining as per numerous credible peer reviewed studies. You have nothing to fear from a 560 ppm (the much hyped doubling) CO2 content. Without negative feedbacks the consequent temp increase is probably less than 1.2c. Much less than the range of natural variation and even with the temp increase less than the global average temp of most of the holocene.

Sumner's residence time denial argument is easily debunked. CO2 concentration has risen 40% since man started emitting vast amounts of CO2. Natural, I think knot.

The global temp has already risen .8C even with just a 40% increase in CO2 concentration. Since ECS equilibrium takes hundreds to thousands of years, the temp will continue to rise, even with holding CO2 concentration at present levels

The range of ECS estimates:

Saw a nice story today about a guy who walked the length of the Keystone Pipeline path, and he had an insight that strikes at the heart of the topic in this thread:
Itís not just education, though. Itís about their identity and economic situation. On the Great Plains I came across countless ghost towns and abandoned homes. The folks out there realize the sense of mortality when it comes to community. So any project thatís going to bring in a bit of money is not going to be questioned on the grounds of climate change or pollution. Itís going to be greeted with open arms if it can help their community last a bit longer.

These are folks who see themselves as hardy, self-sufficient, small government individualists. If you believe in climate change, youíre giving in to the idea of government coming in to fix things, collective action to impose greenhouse gas limits, and reining in the evils of the free market with stricter regulation. This conflicts with so much of that heartland identity.

By the time your generation starts voting, marrying, and having children of your own you will be plunged into adapting to a new, more uncertain world Ė a world where Arctic sea ice might be all but gone, where desertification could be marching across the planet, where marine ecosystems like coral reefs may be collapsing altogether, and where seas will continue to swamp coastal and island people. You and your peers will face challenges as a society we canít even imagine now.

Sea level rise is already a problem.
