The EU elites and bureaucrats continue to beclown themselves...they are now going to pursue CO2 emission reductions that will accomplish zilch for the climate....
The EU members have just agreed to reducing, by 2030AD, their own CO2 emissions by 40% based on 1990 levels (4.5 billion CO2 tonnes in 1990), for the next 17 years (including 2014, until the end of 2030).
That would simply average out to a 106 million tonne reduction per year. The result by end of 2030 would be 1.8 billion less tonnes emitted by EU countries, per year - assuming they can force every single EU country to comply (stop it! no laughing).
For context, the EU since 1990 has reduced their annual CO2 emissions by 598 million tonnes, total. That is an average of 26 million tonnes per year of reduction success since the end of 1990 - a fraction of the 106 million tonne per year reduction average needed for the next 17 years.
What would be the impact on global temperatures if the EU could wave a wand and immediately reduce their current emissions by 1.8 billion tonnes/year?
Absolutely NOTHING....their reduction plans essentially have an unmeasurable yearly impact of global temperatures (i.e. 'unmeasurable' not being at least a 2 decimal point degree (C) decrease/increase, for example, -0.01, -0.02, +0.01, +0.01 and etc.).
The basic arithmetic of CO2's past impact on global temperatures can be determined utilizing the standard 3rd party estimates of total global temperature increase and total CO2 emissions from 1850 on.
Using the historical CO2 emission and temp records, since 1850 global temperatures have increased by 0.00000000000061°C per CO2 tonne emitted (assuming the climate-doomsday alarmists' claims that all warming is due to CO2 and that all human emissions remain in the atmosphere from hundreds to thousands of years).
As can be seen with the above depiction of the 'C3' CO2/temperature estimator, the total reduction of 1.8 billions tonnes of CO2 emissions will have absolutely no yearly measurable impact on global temperatures (top panel of depiction).
(The various arithmetic calculations are not difficult, however they are tedious. So instead, one can use this simple 'C3' estimation tool to broadly estimate the impact of CO2 reductions/avoidance (or additions) on global temps.)
Since an immediate 1.8 billion tonne annual reduction is not possible, but a 106 million tonne reduction/year over the next 37 years (including 2014 through the end of 2050) could possibly be accomplished, what is the temperature impact with that scenario?
Again, absolutely no measurable impact on global temperatures (bottom panel of depiction). That's zero impact after 37 years of avoiding 106 million emission tonnes/year.
And by now you are probably asking yourself just how many years the EU has to reduce their CO2 emissions by 106 million tonnes per year for a measurable impact to be produced (i.e. -0.01 degree change)?
Approximately 165 years from end of 2013! But wait...there's more absurdity...if they're reducing CO2 emissions by 106 million tonnes per year, the EU finally gets to zero CO2 emissions by year 2056 (43 years from end of 2013 - currently, the EU emissions per year are about 3.9 billion tonnes per year).
Well, it means the EU won't ever reach the 165 year mark in CO2 reductions to achieve a -0.01 degree impact. And two, over the next 43 years, despite the 106 million tonnes/year reduction, the EU will still emit another 74.5 billion tonnes in total. That translates into a global temperature impact of +0.04.
On top of this obvious futility from the EU's newest CO2 moral posturing, the other countries of the world will just keep emitting CO2, completely wiping out any reduction the EU achieves. Simply put, no one gives a flying f*#k what the EU does any longer - not Russia, not China, not India, not Brazil nor any other nation on the cusp of climbing out of economic poverty.
Even if other major emitters were to go along with the EU's preening, they will simply ignore their CO2 promises to protect their economies and their citizens. And what will the EU do do enforce their moral superiority? Hmmm...think Russia's wars with the Ukraine and Georgia or think Iran and nuclear weapons - yep, you're right, in diplomatic-speak, the EU can't and won't do squat.
The EU's latest CO2 self-righteousness is as worthless as used toilet paper and everyone knows it.
