Global CO2 emissions continue to increase: report

Global emissions of carbon dioxide (CO2) increased by 3% last year, reaching an all-time high of 34 billion tonnes in 2011.

In China, the world's most populous country, average of CO2 increased by 9% to 7.2 tonnes per capita. China is now within the range of 6 to 19 tonnes per capita emissions of the major industrialised countries. In the European Union, CO2 emissions dropped by 3% to 7.5 tonnes per capita. The remain one of the largest emitters of CO2, with 17.3 tones per capita, despite a decline due to the recession in 2008-2009, high oil prices and an increased share of natural gas. These are the main findings of the annual report 'Trends in global CO2 emissions', released today by the European Commission's Joint Research Centre (JRC) and the Netherlands Environmental Assessment Agency (PBL).

Based on recent results from the Emissions Database for Global Atmospheric Research (EDGAR) and latest statistics on energy use and relevant activities such as gas flaring and cement production, the report shows that global CO2 emissions continued to grow in 2011, despite reductions in OECD countries. Weak economic conditions, a mild winter, and energy savings stimulated by high oil prices led to a decrease of 3% in CO2 emissions in the European Union and of 2% in both the United States and Japan. Emissions from OECD countries now account for only one third of global CO2 emissions – the same share as that of China and India combined, where emissions increased by 9% and 6% respectively in 2011. Economic growth in China led to significant increases in fossil fuel consumption driven by construction and infrastructure expansion. The growth in cement and steel production caused China's domestic coal consumption to increase by 9.7%.

The 3% increase in global CO2 emissions in 2011 is above the past decade's average annual increase of 2.7%, with a decrease in 2008 and a surge of 5% in 2010. The top emitters contributing to the 34 billion tonnes of CO2 emitted globally in 2011 are: China (29%), the United States (16%), the European Union (11%), India (6%), the Russian Federation (5%) and Japan (4%).

Cumulative CO2 emissions call for action

An estimated cumulative global total of 420 billion tonnes of CO2 were emitted between 2000 and 2011 due to human activities, including deforestation. Scientific literature suggests that limiting the rise in average global temperature to 2°C above pre-industrial levels – the target internationally adopted in UN climate negotiations – is possible only if cumulative CO2 emissions in the period 2000-2050 do not exceed 1 000 to 1 500 billion tonnes. If the current global trend of increasing CO2 emissions continues, cumulative emissions will surpass this limit within the next two decades.

Fortunately, this trend is being mitigated by the expansion of renewable energy supplies, especially solar and wind energy and biofuels. The global share of these so-called modern renewables, which exclude hydropower, is growing at an accelerated speed and quadrupled from 1992 to 2011. This potentially represents about 0.8 billion tonnes of CO2 emissions avoided as a result of using renewable energy supplies in 2011, which is close to Germany's total CO2 emissions in 2011.

China and India ... the dynamic duo fightin off the next ice age.

Thanks to Al Gore and the AGW cult! (and as VD reminded us: Enron)

Volcanos and other natural processes released (at a high, generous estimate) 2 billion tons in the same period, about one half of one percent of human activities.

If natural processes can affect the environment and climate, why are there people who deny that taking 200 times more carbon out of the ground and throwing it into the atmospheric chemistry mix has an even greater effect?

Thanks to Al Gore and the AGW cult!

Do you honestly think people take what you have to say seriously?

1) Annual carbon flux from natural sources = 750,000 billion tonnes.

2) Recently it was discovered that there are approximately 3,000,000 undersea volcanoes no one knew anything about. How much CO2 do they give off?

3) Does any sane person think that climate scientists know exactly how much CO2 nature gives off?

4) In the Eemian, CO2 rose 100ppm with no human intervention and it rose after temperature. Nature gives off more CO2 if it gets warmer.

5) Kyoto was a money making scam for Gore and Enron.

That's more than the mass of the entire atmosphere. You're off by a factor of several thousand. You then go on to say that nobody knows how much CO2 nature gives off (bs), negating your outrageously inflated made up lie anyway.

Ooops. 750 billion tonnes.

Still baloney.
Humans produce about 135 times as much CO2 as nature releases.

http://news.disco...627.html

The idea that we can't measure output is ridiculous. The amount of CO2 in the atmosphere is a known quantity. The amount of CO2 produced by humans is a known quantity, measurable by simply calculating fuel consumption.
Subtract one from the other. No obfuscation necessary.

Nonsense. About 3% according the cult.

And a large percentage of that is agriculture/deforestation and land use changes. And cement.

The amount of CO2 in the atmosphere fluctuates 3ppm to 9ppm over a year because of plants growth and death.

We have no definitive proof that CO2 isn't outgassing from the oceans or that agriculture or nature isn't producing extra CO2.

Back up your claim. I have.

The amount of CO2 released by human activity is known. The amount of CO2 in the atmosphere is known. Simple extrapolation; human output dwarfs natural output.

in order for volcanic emissions to match those made by humans, the May 18, 1980, Mount St. Helens eruption would need to happen every 2.5 hours.

That would be 3500 per year. Or, if the 3,000,000 undersea volcanoes produce .1% each of what Mt St Helens produces, it would cover it.

The oceans contain 37,400 billion tons (GT) of suspended carbon,

land biomass has 2000-3000 GT.

The atpmosphere contains 720 billion tons of CO2 and

humans contribute only 6 GT additional load on this balance.

390 ppm of CO2 equates to 3,100 gigatons in the atmosphere.
Humans are putting out 34 gigatons per year.

Finding new undersea volcanos doesn't increase the amount of CO2 released. The total amount of CO2 in the atmosphere is known, no matter what the source. The amount of CO2 released by human activities is known. The amount of CO2 the oceans and biomass can absorb is known. Simple extrapolation then reveals that nature is responsible for only less than a percent of the CO2 emitted per year.
Uncovering new sources of CO2 is irrelevent to the measurable amount of CO2 that is present. If it got there from 3 million or 3 billion volcanos, it's irrelevent and an attempt at obfuscation.
Human activity is known. Biomass and ocean absorption is known. Atmospheric content is known.
Unless you can show that simple arithmetic is wrong, your position is crap.

Humans are supposedly contributing 6ppm to atmospheric CO2 levels.

But CO2 is only rising around 2ppm.

That means the plant is absorbing 4ppm extra each year.

If the plant can absorb an extra 4, why not 6?

And maybe natural CO2 is going up 4ppm and humans are producing 6ppm, but the planet is only absorbing 8ppm extra.

There are a lot of huge guesses.

Recently on physorg ther ewas a paper saying the first 1 billion people caused land us changes that resulted in 9% of the human CO2.

The next 6 billion people would logically produce another 54% of CO2 via land use.

etc etc

3 million undersea volcanoes

http://www.newsci...ves.html

"We first estimated that there were
about 300 droplet streams rising from the 10 m2
area of the Champagne site, and that each stream
contained 2 droplets/s, each with an average diameter
of 1.5 cm. This gives a total liquid CO2
flux of 1 liter/s or 1 kg/s (assuming a density of
1g/cm3), equivalent to 23 moles CO2/s. Using a
similar method, we estimate the CO2 flux from the
Champagne hot vents to be 0.5 mole/s or only
about 2% of the liquid CO2 flux. The CO2 flux
from the liquid droplets at the Champagne site (8
108 moles/yr) approximately equals the combined
carbon flux from all of the Endeavour Ridge vent
fields on the Juan de Fuca Ridge [Rosenberg et al.,
1988; Lilley et al., 1993], or about 0.1% of the
global MOR carbon flux ... "

On one side you have people who are denying pretty straightforward physics because the solutions being proposed make them fear a loss of their freedom.

On the other side you have people using pretty straightforward and undeniable arguments about physics to propose solutions which are highly political and agenda laden.

Hence the conversation is never about what's going on with the planet anymore, but entirely about fear and politics.

You're just not getting it. Or you're purposefully trying to obfuscate the issue. Let's make this perfectly clear:

The question is, Who produces more CO2, nature or man?
The variables are: Manmade CO2, Natural CO2, Amount of CO2 in the air, and Amount of CO2 being absorbed.

Three of those four variables are known:
We know how much CO2 people produce, simply by measuring fuel consumption.
We know how much CO2 is in the air, simply by measuring atmospheric content.
We know how much CO2 is absorbed, simply by calculating how much biomass and ocean there is and measuring how much each can absorb.

Nature releases less than 1% of the CO2 that human activities do. CO2 is rising. Therefore, humans are responsible for at least 99% of it, even discounting that there may not be a rise at all if absorption exceeds production. Obviously, it does, though, because it is rising.

How many volcanos there are is irrelevent. Your attempts at misdirection is blatantly wrong.

Nature

We know how much CO2 people produce, simply by measuring fuel consumption.


"25 and 30 percent of the greenhouse gases released into the atmosphere each year 1.6 billion tonnes is caused by deforestation"

"Concrete is responsible for 7-10% of CO2 emissions worldwide"

etc etc

Bzzzt. You lose.

In other words, human produced CO2 is quantifiable.
Subsequently, so is nature's.

Study (http://volcano.or...man.html ) show that human related activities dwarf natural emissions.

"the natural decay of organic material in forests and grasslands and the action of forest fires results in the release of about 439 gigatonnes of carbon dioxide every year, while new growth entirely counteracts this effect, absorbing 450 gigatonnes per year"

"In 2010, 9.14 gigatonnes of carbon (33.5 gigatonnes of CO2) were released from fossil fuels and cement production"

439 9 = 448

They are guessing. The error bars are huge.

Even with crap data (claiming it's impossible to quantify natural CO2 emissions, then going on to throw out unsubstantiated figures), he still misrepresents things in an attempt to obfuscate.
Adding only human produced carbon, not the whole CO2 amount, to what he claims is nature's CO2.
Lies, obfuscation, and more lies. No one takes you seriously, NP. You're irrelevant. Take the last word, if you want it, I'm out.

I await your numbers.

Try not to tell another whopper.

"Around half of all carbon dioxide produced by humans since the industrial revolution has dissolved into the world's oceans"

1) How did the oceans know which molecules of CO2 to reject?

2) Why only half?

Jul 21, 2012
why does it continue to increase while people are being made so poor?

The tactic doesnt work. poor people become poor , middle class either become richer or poorer, the people with more money just consume more and more.
Equal dividing and taxing CO2 is the only solution. Making people poor is not the solution. You have to reward people doing the right thing and punish people for consuming eg, make green food cheap make meat expensive, make fuel expensive, but make keep fuel cheap for the green food industry and reward them for being fuel efficient, punish the import of food for meat industry.

Jul 21, 2012
from personal experience, my family has never driven a car for ages. we consume very little, i even work in the dark behind my computer with special glasses.

And now i am being punished because the price of everything increases due to an intentionally crippled economy.

I have been punished for doing the right thing. Obviously that is not enough and i must die, even though i have dozens of projects that go beyond carbon neutral.

Making people poor doesnt work, it only makes it worse.

Jul 22, 2012
Then you had better not vote Republican since they are the party of poverty and wealth stratification.
