There are no free passes on fossil fuel carbon taxes although low income wager earners receive a carbon tax rebate.

If all the increase is from the ocean, then that means all the fossil - fuel carbon dioxide is going somewhere that scientists haven't discovered yet.

The climate response to this forcing and society's response to climate change are complicated by the system's inertia, mainly due to the ocean and the ice sheets on Greenland and Antarctica together with the long residence time of fossil fuel carbon in the climate system.

There is more fossil fuel carbon available than the size of the terrestrial biosphere, including soil carbon, so I didn't bother with it.

«Our findings show that if we do not want to melt Antarctica, we can't keep taking fossil fuel carbon out of the ground and just dumping it into the atmosphere as CO2, like we've been doing,» says one of the report's authors, Ken Caldeira, an atmospheric scientist at Stanford University's Carnegie Institution for Science, California.

Because of a regulatory loophole that passed European Parliament recently, the European Union still considers biomass fuels carbon - neutral, allowing them to count toward fulfillment of its Paris Agreement commitments.

And changes in chemistry brought about by the fossil - fuel carbon now accumulating in the ocean will raise the carbonate compensation depth, rather as a warmer atmosphere raises the snowline on mountains.

But I can see business as usual unfolding easy enough with fossil fuel carbon emissions still rising ever higher into 2040 and beyond.

The 2009 State of the Climate report gives these top indicators: humans emitted 30 billion tons of of CO2 into the atmosphere each year from the burning of fossil fuels (oil, coal, and natural gas), less oxygen in the air from the burning of fossil fuels, rising fossil fuel carbon in corals, nights warming faster than days, satellites show less of the earth's heat escaping into space, cooling of the stratosphere or upper atmosphere, warming of the troposphere or lower atmosphere, etc..

Fuel carbon intensity reduction from 2015 - 2030 from fuel deployment scenarios for the Pacific Coast region.

Even if CCS is deployed in line with an optimistic scenario by 2050, fossil fuel carbon budgets would only be extended by 125GtCO2, allowing the equivalent to 4 % of current global reserves to be burned as long as their emissions are captured and stored.

«If the natural concentration had been a factor of two or more lower, the climate impacts of fossil fuel carbon dioxide release would have occurred about 50 or more years sooner, making it much more challenging for the developing human society to scientifically understand the phenomenon of humanmade climate change in time to prevent it,» he says.

Documents reportedly show warnings made in 1968 of «catastrophic effects» from fossil fuel carbon emissions

Well - to - wheels vehicle emissions (gCO2 equiv.km - 1) by energy source, vehicle energy intensity (MJkm - 1), and fuel carbon intensity (gCO2 equiv.

The average rate of injection of carbon into the climate system during these hyperthermals was slower than the present human - made injection of fossil fuel carbon, yet it was faster than the time scale for removal of carbon from the surface reservoirs via the weathering process [3], [208], which is tens to hundreds of thousands of years.

Thus fossil fuel carbon is the crucial human input that must be limited.

Indeed, the long lifetime of fossil fuel carbon in the climate system and persistence of the ocean warming ensure that «slow» feedbacks, such as ice sheet disintegration, changes of the global vegetation distribution, melting of permafrost, and possible release of methane from methane hydrates on continental shelves, would also have time to come into play.

Most fossil fuel carbon will remain in the climate system more than 100,000 years, so it is essential to limit the emission of fossil fuel carbon.

The long lifetime of the fossil fuel carbon in the climate system and the persistence of ocean warming for millennia [201] provide sufficient time for the climate system to achieve full response to the fast feedback processes included in the 3 °C climate sensitivity.

So there are cycles, possibly related to ocean conditions in the Pacific, which can bring about super-droughts even without fossil fuelled carbon in the atmosphere.

We focus on fossil fuel carbon, because of its long lifetime in the carbon cycle.

Reversing the effects of deforestation is also important and there will need to be incentives to achieve increased carbon storage in the biosphere and soil, but the crucial requirement now is to limit the amount of fossil fuel carbon in the air.
