Unexpected threats to the health of global systems keep emerging. Twenty years ago we didn't recognize global warming. Ten years ago we didn't know about ocean acidification. This might be the landmark week in which a broad public recognized a new threat to the global climate -- black carbon.

The United Nations Environment Programme (UNEP) has just published a science-based analysis of the climate forcing effects of black carbon. The findings are that cutting black carbon and troposperhic ozone now could halve regional warming for 30 to 60 years and reduce global warming by half a degree. It turns out that reducing black carbon emissions needs to become a priority. According to the United Nations Economic Commission for Europe (UNECE), greenhouse gas reductions alone will not avert further destruction of the arctic; black carbon and ozone reductions are needed.

Black carbon is made up of fine particles. It is colloquially known as soot. It comes from diesel engines as well as burning wood, waste and gas. The health effects of black carbon are well known. In London, for example, the soot from our beloved taxis and other sources leads to the early death of 4,500 people a year according to the government.

But black carbon's effects on the climate are just beginning to gain prominence. Recently, black carbon appeared in proposed climate legislation in the US (the Waxman-Markley Bill and the Kerry-Boxer Bill). In January the European Parliament called for the European Commission to acknowledge black carbon as a threat and include it in laws that protect against climate change. No action, however, has yet been taken on either side of the Atlantic.

I established ClientEarth as Europe's first public interest environmental law organization to provide the legal expertise needed to drive such action forward, and our team have been investigating what needs to be done. The EU could act now and impose black carbon specific monitoring and reporting obligations; move to retrofit or scrap old diesel engines; move away from diesel as a fuel source for engines in cars; create black carbon obligations for ships calling at EU ports; and it could seriously examine measures to reduce the emissions from residential burning of wood and implement better controls for open land burning.

Estimates are that black carbon may be the second or third biggest contributor to global warming after CO2. It is a short term "climate forcer" which means that we could make an instant impact on global warming -- this is crucial, the arctic is a key 'tipping point' for global warming.

It's a good thing that black carbon is increasingly being talked about in environmental and policy circles. Here in Europe ClientEarth and others will be working to ensure that talk becomes action as quickly as possible.

Employing Thermal Anaerobic Gasification technology when extracting energy from fossil fuels effectively eliminates 100% of the carbon from being discharged to the atmosphere.

Almost all of the carbon, including soot, is a result of combustion. Combustion requires O2, and that binds with C, S, and N to create GHGe.

TAG systems capture the carbon as a solid material. It doesn't ever get into the flue. WAIT - TAG plants don't have flue stacks. They don't need them.

I believe that the people "discussing" black carbon, looking for regulatory solutions will be confronted with operating TAG technology soon. The TAG plants will be eliminating carbon long before the conversation currently being tendered comes up with any viable solution to the situation.

Part of the problem and in fact the root of the problem with responding to articles like this is where is the science? Are their links to peer read scientific studies that allow you to see their methodologies on how they gathered their data and crunched it into results driven political ideologies.

And in intellectual ghettos such as these, the best you can do is make a factual statement backed up with an argument based on data you can provide a link to. That provides context for 50 more people to post their arguments and their scientific data to engage in an online debate based on credible information as it were.

But then again, that is precisely what higher education distance learning online chat rooms are all about. Thus we just pop off our opinion and let it go at that as being factual. Hrrrrmph.

Soot is a "cooler" since it blocks sunlight. Artificial attempts to cool the planet still doesn't lower excess CO2, however.

Ok, I read the whole thing and nowhere does it explain {why} soot could be a warming forcer... I just don't get it. No wonder conspiracy theorists and skeptics don't believe GW. Besides, there just can't be a law against wood burning stoves (or many will revolt!) because that is neutral CO2 emittance.

Are you talking about soot that is scattered in ten quintillion particulates on every leaf and twig in an old growth forest from the aftermath of a raging forest fire in Northern California?

Or the soot that is dispersed into the troposphere from say a line of 8 diesel locomotives hauling 2 miles of freight cars through Cheyenne WY to Seattle WA?

Or the soot settled down in a campfire pit? And to what degree is the singular or delineated collective dose response impacts going to be in measured amount on the health effects to the planets living systems?

How do you do.

I thought coal was the biggest contributor to soot.

Present approaches to cutting back on carbon are much too slow to meet the demands of climate change.

An unpublicized National Security threat can open a new path that might garner broad political support.

See Green Light at www.aesopinstitute.org for an overview and some of the new possibilities for accelerating wise action.

Diesel engines may be modified to run on water. Many experiments are under way to convert existing engines to utilize some water which results in reduced emissions.

Future engines can be designed to run on fractional Hydrogen using only water as fuel. One gallon of ordinary H2O might power a hybrid car or truck 1,000 miles.

See Running on Water on the same web site.

I agree.

The game is over for the very simple reason that there will never be any changes coming from political leadership because there is no incentive to given they rely on the political economy and that means status quo for bottom-line profit statements for the fossil fuel framework (FFF)for nearly every human activity we are engaged in. Add to that outside of what you saw in Seattle in 1999 and expand that response a hundred fold meaning it comes from the bottom.

But ultimately its over for the very simple reason we do not have anything now or even on the horizon unless someone has a rabbit to pull out of their hat at the last minute, but given that the planets entire economic existence is built on a framework of fossil fuel; production and add to that the average compound economic growth of 3% per year; and BTW look around the world and ask, "3% of everything I see around me in a FFF " then add Asia into the growth model of expanding their industrial base also built on fossil fuel and the inescapable truth smacks you in the face.

There was a nice surprise today. An old friend forwarded an article about Joule Energy and their remarkable breakthrough in replacing fossil fuel with inexpensive liquid fuel from sunlight.

This is a very hopeful technology. See Moving Beyond Oil on the Aesop Institute website and google them for more information.

In a court of law, an expert witness is a witness, who by virtue of education, training, skill, or experience, is believed to have expertise and specialized knowledge of a particular subject beyond that of the average person.

That said, if we went to court to settle the global warming issue, who would the deniers call as their expert witnesses?

The deniers would call James "Mountain Jim" Inhofe.

We'd bring the National Academy of Science of the United States of America.

As a matter of fact, we could pick any one of 32 National Science Academies.

The deniers would call Patrick Michaels.

We'd counter with the American Geophysical Union and its 58,287 members.

The AGU was established over 90 years ago, and for more than 50 years has operated as an unincorporated affiliate of the National Academy of Sciences. These aren’t “NOBODIES”. The National Academy of Sciences is like the Supreme Court of science; they are the best of the best when it comes to science, of an entire nation.

The deniers would call Khabibullo Abdusamatov, a 70 yr old Russian astrophysicist.

We'd bring Stephen Hawking.

The deniers would call 87 year old Fred Singer.

We'd bring the American Institute of Physics.

The AIP has been publishing scientific journals for almost 80 years.

The deniers would bring Henrik Svensmark a physicist at the Danish National Space Center.

We'd bring NASA.

We'd could bring every scientific organization in the world because they all agree with the conclusions of the IPCC.

CO2 causes warming. But for it to warm at any substantial level you need the sensitivity from positive feedbacks. These feedbacks are currently not happening. These are facts.

Please explain the sustained 1.6 C/century temperature rise we've bee having for the last 40 years. On your mark! Get set! G-O-O-O!

Ah, I think I see the problem here. Sure, CO2 causes warming. But then, warmer air can hold a lot more water vapor, which holds more heat, etc. There is your positive feedback. There is why just a tiny percentage of CO2 can have such a potent impact.

Glad I could help.

You forgot, that this debate would be held in a closed session of Congress and only the right wing deniers would be allowed to talk to the press afterwards.

If it isn't good for Big energy companies bottom line, then it is bad science and the mere mention of the existence of a problem is not covered in what some say is MSM - which they try to say is liberal...and if these liberal media outlets don't cover it then it doesn't exist. Sad, but that is how the deniers have punked the public in US into believing that there is no such thing as climate change, etc.

The effect of global warming towards environment was so drastic. Since then the revenge of nature was quite noticeable. We still have time to help restore the health of nature for us to be healthy and safe as well.

In the United States the Koch brothers and their fossil fuel allies have subverted our government institutions. Decades have been wasted bickering. Any suggestions on how to counter this?

Yes, in fact. Stop absorbing information from activist memos and start doing your own research.

With stringent federal disclosure guidelines in place we can factually state that unions (by example rather than scapegoating) are donating more at an exponential rate to their favorite party than do the brothers mentioned.To fully understand the global carbon emittance situation you need to look at China and India as well as ourselves,of course. To distill: how is a Chinese person making 1$ an hour going to afford a Prius. Progress to this real problem of warming will be done by businesses who pay top dollar for great minds.

"Twenty years ago we didn't recognize global warming."

That's odd, Al Gore was taught about it in college, in the '60s. If by "we" you mean the US public - the majority of them still don't recognize it.

Greenhouse gases causing warming, yes. However, the feedback sensitivity is unknown and is currently making a mockery of the models.And for people that want to take out insurance for polar bears and Caribbean Islands I would tell them to buy stocks in GE or Intel - companies well positioned to get us to alternative energy adoption.

About 30% of my assets are invested in solar PV stock. Intel and GE will have no presence in alternative energy, none whatsoever. Nuclear is dead. Bush planned to have ten nuclear plants built in US when he took office. Instead none were built, and only one (in GA) is still even planned. If you're an investor, don't invest in nuclear. It's not green enough for us greenies, and if you don't believe in global warming, you might as well burn coal, it's cheaper.

Forcings and feedback are known well enough to put error bars on projects 100 years from now. That ain't shabby.
11:09 PM on 02/25/2011
Gore wasn't taught about it in college, but it has been in the atmospheric science community as a live topic since the early 70's. It was until late 80's the signal came clearly out of the noise.

In the 70s we were headed for an ice age.
