Climate Action Plans Fail to Deliver
Around the country, localities, states and multi-state regions are convening Climate Change Task Forces aimed at developing plans to reduce greenhouse gas emissions.
As the name suggests, these groups have been created to develop Climate Action Plans that are intended to lessen the projected impacts of anthropogenic climate change around the world in general, but more particularly, in each state.
In every case, the Action Plans include a lengthy list of cookie-cut, prescribed actions spread across all segments of society, and that are aimed towards reducing future emissions of greenhouse gases to a level below some arbitrarily set target. In no case do any of the Plans lay out what quantified effects their recommended emissions cuts will have on local, regional or global climate. The reason why not? None of the Climate Action Plans will have any meaningful effect on the climate – or any change in future temperatures or sea levels.
In 2007, global emissions of carbon dioxide (CO2) — the primary greenhouse gas emitted by human industrial activities — totaled 27,600 million metric tons (mmtCO2). The United States, as a whole, contributed 5,900 mmtCO2 to that total, or about 21.4%. Individual localities, states, etc., contributed much less (see columns 2 and 3 in the Table below for a state by state breakdown of total and percentage of global emissions).
Even more importantly, the percentage of global, manmade CO2 emissions from the U. S. (and each individual state) will decrease over the 21st century as the growing demand for power in developing countries such as China and India – and beginning in 2012, the Middle East – rapidly outpaces the growth of our CO2 emissions (EIA, 2007).
During the past 5 years, global emissions of CO2 from human activity have increased at an average rate of 3.5%/yr, with China alone contributing nearly 2/3rds of the new emissions (Netherlands Environmental Assessment Agency, 2008). This means that the annual increase of global CO2 emissions is several times greater than the total emissions from most of the individual 50 states.
Therefore, even a cessation of all CO2 emissions from any particular state will be completely subsumed by global emissions growth in only a matter of months! In fact, emissions increases produced by China alone rapidly overwhelm any emissions reductions made in the U.S. (see columns 4 and 5 of the Table below for a breakdown of how quickly statewide emissions cessations are subsumed by emissions growth globally and by China alone). Given the magnitude of global emissions and the rate of global emission growth, even regulations prescribing a complete cessation, rather than a partial reduction, of local, state, or even national CO2 emissions will have absolutely no meaningful effect on global climate.
In other words, state mitigation plans are “all pain and no gain” – a folly bordering on official malfeasance.
As a demonstration of this, we employ the methodology used by Wigley (1998). Wigley undertook an examination of the climate impact of participating nations’ adherence to the CO2 emissions controls agreed under the UN’s Kyoto Protocol. He found that if all developed countries meet their commitments in 2010 and maintain them through 2100, with a mid-range sensitivity of surface temperature to changes in CO2, the amount of warming “saved” by the Kyoto Protocol would be 0.07°C by 2050 and 0.15°C by 2100. The global sea level rise “saved” would be 2.6 cm, or about one inch.
By comparison, a complete cessation of CO2 emissions by individual states [allowing not so much as a camp fire] amounts to only a tiny fraction of the worldwide reductions assumed in Wigley’s global analysis. Thus, state and regional mitigation impacts on future trends in global temperature and sea level will be only a minuscule fraction of the calculated, negligible global effects claimed for Kyoto.
To demonstrate the futility of state-by-state emissions regulations, we apply Wigley’s (1998) methodology to each individual state, under the following assumptions: 1) the ratio of U.S. CO2 emissions to those of the developed countries which have agreed to limits under the Kyoto Protocol remains constant at 39% throughout the 21st century; 2) that developing countries such as China and India continue to emit at an increasing rate —consequently, the annual proportion of global CO2 emissions from human activity that is contributed by human activity in the United States will decline; and 3) that the proportion of total U.S. CO2 emissions from each state remains constant throughout the 21st century.
With these assumptions and using Wigley’s (1998) mid-range future emission scenario, we can calculate the climate effects (on global temperatures and sea level rise) that each state might achieve by actually exceeding their Climate Task Force recommendations to the point of zero emissions now and forever.
Columns 6 through 9 of the table below demonstrate the futility of such actions by presenting the temperature “savings” and sea level rise “savings” that a complete emissions cessation by each individual state would achieve by the year 2050 and 2100. Not a single state acting alone slows the projected rate of global temperature increase such that it reduces the total temperature rise by the end of the century by even two one-hundredths of a degree Celsius or slows sea level rise by more than one-half a centimeter (two-tenths of an inch).
Putting an even finer point on it, were the entire U.S. to close down its economy completely and revert to the Stone Age, without even the ability to light fires, the growth in emissions from China alone would replace its entire emissions in a little less than a decade. In this context, mere emissions restrictions enacted by any locality, state, or multi-state region would be extravagantly pointless.
Pres-Elect Obama’s Cap and Trade Proposal
President-elect Obama has promised to “bankrupt” the coal industry with the most draconian cap and trade scheme in the world.
Under his announced greenhouse gas emissions reduction plan, he proposes to reduce the U.S.’s annual greenhouse house gas emissions total such that the U.S. total emissions in the year 2020 are the same as what the U.S. total emissions were in the year 1990. Even further, he vows to reduce total greenhouse gas emissions from the U.S. to 80% below what they were in 1990 by the year 2050.
The numbers look something like this (all numbers are in million metric tons CO2):
Now, let’s compare the total emissions savings (under the Obama plan) to annual growth in CO2 emissions from countries besides the United States.
Averaged over the last 5 years, the growth rate in global CO2 emissions (not including the U.S.) has been about 920 mmtCO2 per year. That means, if Obama’s entire goal of limiting U.S. CO2 emissions to a level that is 80% below 1990 levels, or to a value of 1003 mmtCO2/year, could be met tomorrow—the entire emissions savings under his plan (4981 mmtCO2/yr) would be completely replaced by new emissions in the rest of the world in less than 5 and a half years.
If, instead of reaching the desired goal tomorrow, it was met by reducing our annual CO2 emissions by 116 mmtCO2/year for the next 43 years (quite a feat considering that for the past 10 years we have averaged a year-over-year increase of about 41 mmtCO2/yr), each year’s annual savings would be replaced by global emissions growth within about the first 6 weeks of each year. That’s a lot of continuing struggle every year for us to be simply swept away in six weeks by emissions growth in the rest of the world (primarily China and India who make up about 2/3rds of the current annual emissions growth).
The result of all of this would be negligible supposed climate gain in the face of irreparable social, political and economic outcomes.
That is to say, assuming the UN’s mid-range sensitivity for a doubling of CO2, the modeled result of an 80% below 1990 level reduction of U.S. emissions by the year 2050 would have the effective impact of simply delaying the total rise in global temperature and global sea levels by about 6-7 years. Differently put, the global average temperature in the year 2050 under Obama’s plan would be less than two-tenths of a degree F lower than it otherwise would have been in the year 2050. The global sea level would be about one-half an inch lower than where it otherwise would have been.
These impacts on the climate [even if scientifically believable] are, for all intents and purposes scientifically and physically meaningless.
Impact of the European Union Actions
Oftentimes, the actions of the European Union aimed towards reducing carbon dioxide emissions are held up as an example of how to combat climate change through decisive government action. But as with the U.S., the EU is actually quite ineffective when it comes to actually making a difference on global climate by regulating CO2.
It is no secret that the EU talks the talk about climate change, but it doesn't walk the walk. Most EU countries will fail to meet their Kyoto emissions-reduction targets. While the much-reviled US administration succeeded in quietly cutting total US carbon emissions in recent years, the EU's carbon emissions have increased. Also, the EU's first attempt at carbon trading ended in characteristic farce when all member-states except the UK awarded themselves emissions rights that comfortably exceeded previous emissions. Result: the "price" of carbon emissions per ton of CO2 fell below 50 cents, rendering the entire scheme useless. No climatic benefit ensued, and none will ensue from the EU's current scheme, which is nothing more than a purposeless extra cost to already hard-pressed businesses, many of which are finding it simpler to move out of the EU altogether.
In fact, even if the entirety of the EU-27 nations were to completely and forever cease all CO2 emissions from this day forward, it would have an insignificant impact on the course of the world’s future climate (Table 2). In 50 years, the global temperature “savings” produced by an immediate cessation of all EU-27 CO2 emissions is estimated to be less than one-tenth of a degree Celsius, and increasing to just a bit more than a tenth of a degree by centuries end. The impacts of future sea level would be equally miniscule.
Needless to say, the efforts to simply reduce CO2 emissions from individual countries within the EU-27 produce even less of in impact—effectively no climate moderation…no lessening of the global temperature rise, no slowing of global sea level rise, nothing. Worse, all of their efforts will be quickly subsumed by new CO2 emissions resulting from the rapid development and accompanying growth in emissions from the rest of the world, primarily China and India. In fact, a complete cessation of all EU-27 CO2 emissions would be subsumed by new emissions from the rest of the world in under 4 ½ years. For individual EU countries, the timing is even more disheartening. For example, growth in emissions from China would replace the entirety of Austria’s annual emissions in just 47 days, those from Denmark in 31, Spain’s in less than 8 months, and those from the U.K. in just under a year. Monumental efforts gone within a relative blink of an eye.
This is a scenario that — just as in the U.S. — is best described as one which produces no climate gain for incredible economic pain.
