As with all of life's choices, we make risk based decisions,
how much risk is there, and how much will it cost to mitigate said risk.
Some of us do this on an unconscious level, other look at the data and decide.
With AGW, the risks factors come from several variables,
Since you now admit that there is indeed risk, then we can both agree that your earlier statement that there is no risk is in fact utter crapola. Thanks for that.
That depends on how much Republicans continue to block efforts to do something about the climate crisis. If you don't wanna fix the problem, fine. If you prevent the rest of us from fixing the problem, shame on you.How fast will CO2 levels rise?
It's about 2.8, as paleo studies show (e.g. Royer 2007). This is in the middle of the IPCC range.What is the ECS sensitivity of CO2?
Several decades ago.When will viable alternatives be available?
The rate of the CO2 rise so far has been between 2 and 3 ppm per year,
All but the most zealous, think RCP 8.5 is very unlikely, so RCP 2.6, 4.5, and 6.0,
place the CO2 level in 2040, between 450 and 475 ppm, the same 2 and 3 ppm per year.
And what makes you think we're going to suddenly stop burning fossil carbon in 2040, when you're working so hard against that?
It would happen a lot sooner if carbon had to pay its external costs. Right now it's getting a free ride.It looks like man made hydrocarbon fuels, could be brought online quite quickly,
as soon as the feedstock price makes it viable, this will be about $90 a barrel oil.
That's exactly why we tax at the wellhead, the mine, and the import terminal.Adding a fuel carbon tax, will not change what the refineries pay for their feedstock,
and so is both irrelevant and bad for the poor.
Electricity accounts for 60% of US emissions, and oil is already priced out of that market. The real question is when will natural gas price itself out of the market, or more correctly, when will we force it to do so by paying its way on external costs.The question becomes, when will oil cross the $90 a barrel boundary, because
CO2 emission will slow down quickly at that point.
From a business standpoint, once refineries get a taste of stable feedstock supply and price,
they will not want to go back to the very risky business oil extraction.
Synfuels will require little or no refining. Expect refineries to fight tooth and nail to prevent a carbon tax. And in fact they already are: witness the deep funding of climate denial "think tanks" by the oil industry.
