Comments on: A single coal mine that will add 1 ppm CO2 to the atmosphere http://www.climateshifts.org/?p=6176 Science, climate change, coral reefs and the environment Mon, 31 Mar 2014 21:57:00 +0000 hourly 1 http://wordpress.org/?v=3.8.25 By: Paul Deller-Smith http://www.climateshifts.org/?p=6176#comment-3816 Wed, 09 May 2012 00:05:08 +0000 http://www.climateshifts.org/?p=6176#comment-3816 It is all good and fine to say don’t mine the coal and I agree we need to clean up our act.BUT we are not acting globally the greed of a few are destroying the home of all. we need to focus on assisting countries without the means to do it themselves to use more advanced tech to generate Electricity. We will need to mine coking coal for the foreseeable future until other methods of steel production (and other materials) are developed.
As I see it the only way forward is global governance, equality between countries and population control. It is unlikely to happen since as a species we cannot agree from state to state in a single nation. Of course the other factor that will preclude any fast way forward is greed and economics, once free fuel is used no one is going to be happy to pay the current prices for electricity.
there are technologies available to reduce the emissions from coal fired plants but again cost is prohibitive. It strikes me as prudent to mention that here in Australia we have the resources, we have the technology, to build and install, globally, wind turbines and other types of generators but we insist on selling the raw materials. If a strawberry farm is going badly we cry value add make jam. we, as a nation have a very volatile economy and yet we do not value add! The renewable’s market is ripe for exploiting and again Australia is missing the boat

Both must work hand in hand to see the sky rocket success in the coal market news and green house effect.

Have you considered the most important photo chemical reaction in the world?

I think the answer to you question is that many fossil fuel energy suppliers, coal-fire power generators, investors and governments of countries that are rich in fossil fuels like Australia, Canada and Saudi Arabia simply assume that there is no alternative to the current reality where fossil fuels provide the bulk of energy supply. Even though they publicly accept climate science, this lets them feel safe that the current free pass they are getting will go on forever even if climate change causes serious impacts and carbon capture and storage (CCS) remains unviable.

My own belief is that as increasingly dire impacts of climate change are felt, the response to climate change will increase dramatically. It won’t be a smooth, gradual increase but a rapid, jumpy one in response to crisis after crisis.

Large fossil fuel projects are likely to be left as stranded assets with the rapid shift in policy that will occur.

That obviously means investing in a large, long-term fossil fuel project like a big coal mine or tar sands is very risky.

We already know burning just 25% of proven reserves puts us over 2C. So why is nothing like a ban on new fossil fuel exploration discussed at the UNFCCC meetings whose stated goal is now to keep global temps under 2C? I wrote about this in my opening article: http://stephenleahy.net/2010/12/08/cancun-climate-summit-gives-fossil-fuels-a-free-pass/

Why would investors sink their money into something so risky, so certain to be curtailed and penalized?

Given the overwhelming evidence underpinning the role of fossil fuels like coal in driving climate change (large even by comparison to smoking or asbestos) you would have to be concerned about litigation over the impacts if you were a mining company or government involved in supporting it.

Like cigarette and asbestos companies in the 1970s, the coal industry has a growing legal liability but it is yet to see the flood of litigation that will come.

Many people struggle understanding core parts of the Carbon Cycle like this. It is the timescales involved that really amaze me though: http://www.climateshifts.org/?p=750

The question I have now is, what is the liability costs of adding 1 ppm (or 1.6 or 3) to the atmosphere at this stage? Given the scale of the damage that is occurring already, this could be a very large number indeed.

Now, I like using moles because when CO2 is produced by combining O2 with C, the total number of moles in the atmosphere is unchanged (see the spooky plots in TAR and AR4 of decreasing atmospheric oxygen).

Total atmosphere ~ 1.8 x10^20 moles. So, 20 Gt of CO2 is 4.5 x10^14 moles = 2.5 ppm of total atmosphere, if it all stayed in the atmosphere. It doesn’t and my point is that the addition to the atmosphere is only part of the damage.
