Every year the International Energy Agency (IEA) calculates humanity’s CO2 pollution from burning fossil fuels. And once again, the overall story line is one of ever-increasing emissions:
“Global carbon-dioxide emissions from fossil-fuel combustion reached a record high of 31.6 gigatonnes in 2011.”
The world has yet to figure out how to stop the relentless increase in climate pollution. But mixed in with all the bad news there was one shining ray of hope. One of the biggest obstacles to climate action may be shifting. As the IEA highlighted:
“US emissions have now fallen by 430 Mt (7.7%) since 2006, the largest reduction of all countries or regions. This development has arisen from lower oil use in the transport sector … and a substantial shift from coal to gas in the power sector.”
The graph:
How big is a cut of 430 million tonnes of CO2? It’s equal to all CO2 from all Canadians outside Alberta. From a US perspective, it’s equal to eliminating the combined emissions of ten western states: Alaska, Washington, Oregon, Idaho, Montana, North Dakota, South Dakota, Wyoming, Utah and Nevada.
==============================================================
From the IEA, the USA is clearly not the problem:
India’s emissions rose by 140 Mt, or 8.7%, moving it ahead of Russia to become the fourth largest emitter behind China, the United States, and the European Union. Despite these increases, per-capita CO2 emissions in China and India still remain just 63% and 15% of the OECD average respectively.
CO2 emissions in the United States in 2011 fell by 92 Mt, or 1.7%, primarily due to ongoing switching from coal to natural gas in power generation and an exceptionally mild winter, which reduced the demand for space heating. US emissions have now fallen by 430 Mt (7.7%) since 2006, the largest reduction of all countries or regions. This development has arisen from lower oil use in the transport sector (linked to efficiency improvements, higher oil prices and the economic downturn which has cut vehicle miles travelled) and a substantial shift from coal to gas in the power sector. CO2 emissions in the EU in 2011 were lower by 69 Mt, or 1.9%, as sluggish economic growth cut industrial production and a relatively warm winter reduced heating needs. By contrast, Japan’s emissions increased by 28 Mt, or 2.4%, as a result of a substantial increase in the use of fossil fuels in power generation post-Fukushima.
===============================================================
The USA unintentionally achieved Copenhagen style reductions through a combination of economic factors, a change to natural gas, and some dumb luck. It has nothing to do with listening to the shrill whining of people like Bill McKibben and Joe Romm, and the politicians who repeat that shrillness.

The H2S comparison is inane.
The entirety of plant and animal physiology is built on carbon chains, not sulfur ones. The raw material was drawn from the CO2 in the atmosphere, originally hundreds or thousands of times more prevalent than now. The natural “brake” is starvation.
It behooves us to release as much CO2 as possible from sequestration in rock and hydrocarbon liquids as possible, before the plants eat us out of house and home!

For a very long time, while our backwards ancestors scratched out a meager existence, plant life flourished while the human population grew slowly.
But the animal populations were very numerous and they, the plants and humanity tumbled through the natural cycles, despite all that sequestered stuff of life.
What’s so different about modern times, that a massive CO2 dump is necessary?
The fauna are few and trivial compared to the flora. Our most prolific representatives are perhaps the termites, but even they can’t keep up. In any case, the fact is that the flora can and did drive CO2 down to their own starvation level. Only Modern Mankind has the power to unwind some of the millennia of millennia of millennia of suicidal sequestration. Forward!

@Brian H
What level of CO2 is the starvation point? Roughly how many years is “millennia of millenia of millennia”?
Tens of thousands? Millions? A billion? Since there were Ice Ages across many periods of Earth’s history, did the “suicidal sequestration” cause them?
