Biofuels can have a host of negative impacts, from driving up food prices to sucking up more energy than they produce. Hydrogen must be created, requiring either reforming natural gas or electricity to crack water molecules. Biodiesel hybrid electric vehicles (that can plug into the grid overnight) may offer the best transportation solution in the short term, given the energy density of diesel and the carbon neutral ramifications of fuel from plants as well as the emissions of electric engines. A recent study found that the present amount of electricity generation in the U.S. could provide enough energy for the country's entire fleet of automobiles to switch to plug-in hybrids, reducing greenhouse gas emissions in the process.
But plug-in hybrids would still rely on electricity, now predominantly generated by burning dirty coal. Massive investment in low-emission energy generation, whether solar-thermal power or nuclear fission, would be required to radically reduce greenhouse gas emissions. And even more speculative energy sources—hyperefficient photovoltaic cells, solar energy stations in orbit or even fusion—may ultimately be required.
The solutions above offer the outline of a plan to personally avoid contributing to global warming. But should such individual and national efforts fail, there is another, potentially desperate solution:
Experiment Earth—Climate change represents humanity's first planetwide experiment. But, if all else fails, it may not be the last. So-called geoengineering, radical interventions to either block sunlight or reduce greenhouse gases, is a potential last resort for addressing the challenge of climate change.
Among the ideas: releasing sulfate particles in the air to mimic the cooling effects of a massive volcanic eruption; placing millions of small mirrors or lenses in space to deflect sunlight; covering portions of the planet with reflective films to bounce sunlight back into space; fertilizing the oceans with iron or other nutrients to enable plankton to absorb more carbon; and increasing cloud cover or the reflectivity of clouds that already form.
All may have unintended consequences, making the solution worse than the original problem. But it is clear that at least some form of geoengineering will likely be required: capturing carbon dioxide before it is released and storing it in some fashion, either deep beneath the earth, at the bottom of the ocean or in carbonate minerals. Such carbon capture and storage is critical to any serious effort to combat climate change.

Add CommentOne often ignored generator of greenhouse gas, the worst greenhouse gas, namely methane, is the septic tank. It is also a major polluter and health risk since it dumps raw untreated sewage into the environment and nitrates that can cause miscarriage and death of small children. We need to get rid of them and replace them with household treatment systems.
Reply | Report Abuse | Link to thisYou are right, although septic systems are relatively small source compared to sewage treatment plants and landfills. However, there is no doubt that the waste issue (to put it politely) is a large one. Fortunately, there seem to be some good solutions on offer, whether it be capturing the methane produced at landfills and using it as fuel or, dare I say it, recycling some of those other waste products.

Good points were made. Smaller family size was listed near the back but probably should be close to the front of the list. Smaller houses is missing from the list. The statement about divesting oil stocks and investing in companies practicing carbon capture seems simplistic and not well researched. How would selling oil stocks reduce consumption of petroleum products? How many companies practicing carbon storage are traded on stock exchanges? Finally, the statement about bad roads and fuel economy also needs explanation. Is this refering to extra miles driven in Senegal as drivers swerve to avoid holes in the road? I doubt bad roads are even a minor contributor to climate change in comparison to other factors.

Ah the irony of climate change, what I was hoping that someone would point out is that some oil company stocks are exactly the same stocks you would buy if you were investing in carbon capture and storage (so far, only used for things like getting more oil or natural gas out of the ground). As for bad roads, it's not Senegal but the U.S. of A. that I'm talking about. Check your gas mileage between rural routes and interstates (or heck, even just interstates that are poorly maintained).

"Also, how can 7 lbs of gasoline produce 20 lbs of CO2?"
Reply | Report Abuse | Link to thisThe gasoline contributes the "C" part but not the "O2" part. That's contributed by the air through oxidation, or "burning" in the common vernacular. "CO2" means there are two oxygen atoms for each carbon atom. Additionally, each oxygen atom weighs about 4/3 as much as a carbon atom, so if you completely oxidize 7 lbs of carbon into CO2 you get about 25 2/3 lbs of CO2. "25 2/3? But they said 20!" Well, gasoline is part hydrogen too, so that takes away some of that 7 lbs from CO2 production, but hydrogen atoms are only about 1/12 as heavy as carbon atoms so it's not that much of a reduction. The rest is due to incomplete oxidation, making part of the exhaust carbon monoxide, CO, the stuff that makes sitting in a running car in a closed garage so dangerous and such a classic method of suicide.
And I'm not even a chemist!

Here's an idea that needs further thought: It seems to me that it might be better to promote landfilling over incineration and use of virgin fiber rather than recycling pulp when the global carbon balance is considered. When reforesting practices are employed, and used paper is land-filled, is this not an efficient carbon-sequestering cycle even more efficient than original forest?

Reply | Report Abuse | Link to thisHumans have separated themselves from other creatures with several "breakthrough" discoveries. Fire, for example. Tools, the domestication of animals, the wheel, etc. About a hundred years ago, a significant discovery boosted Mankind into our modern dilemma. The fixation of Nitrogen allowed for two world wars, and the explosion of population from 1 billion to 6 billion. The ultimate solution to separating human existence from dependency on the Earth's resources lies in the ability to duplicate what a plant does. Fix Carbon. If humans could create fuel, food, and fiber from air, water and electricity (from non-fossil fuel obviously) and also let loose a benign germ that caused autoimmune contraception, then cohabitation of civilized humanity and all other living creatures could then co-exist.

It is an ineviable fact of life - a force of nature literally! More importantly climate change cannot be stopped. Those who think otherwise should get out more. Yes, there will be adverse consequences - but the sea level was rising long before anthropogenic climate change scams became the biggest hoax in history. Besides the alternative to global warming is global cooling resulting in miles of ice covering much of North America, Asia and Europe. That what you prefer? Me?

The claim "we are tipping the scales" implies two things: First, that there ever was a balance. On just about any scale we look back at the climate of the Earth it is clear there NEVER WAS A BALANCE. Change is the only constant evident. Second, that man is more powerful than nature, than the sun, etc. Yeah, dibiello, you go and believe that if you must but please stop insulting intelligent people by expecting to win them over to your fantasy world please.

http://www.energybulletin.net/21736.html "world food supply just about meets demand, with no reserve to cover further population growth. But the population will grow anyway, and the world's existing grain supply for human consumption is being eroded by three different factors: meat, heat and biofuels."
Biofuels are the developed world's "let them eat cake" solution. There is only one global warming solution that will not result in provoking major war following plummeting living standards due to per capita demand outstripping supplies of food and energy. Nuclear power. Use safe, air-cooled designs from Sweden. Biofuels cannot do it without dooming the world in decades to mass starvation and removing virtually all forests from the planet. We have to stop pretending these "Mother-goose beautiful" fake solutions will work in a holistic picture.

That means about every 70 years we are doubling the amount of CO2 in the atmosphere. Additionally, this model assumes that we continue producing 54 billion tons per year when every reliable source suggests otherwise, that the global continue will continue its current trend of increasing emissions. So we are looking at doubling CO2 AT LEAST every 70 years according to you? Yeah I'd say we are making a difference......
Reply | Report Abuse | Link to thisThe follwoing book offers a major climate change solution. It is based on ecoo-taxation and claims to have the power to turn things around for the environment. There is a lot of information at the publisher's website below.
Reply | Report Abuse | Link to thisThe 21st Century Environmental Revolution: A Comprehensive Strategy for Conservation, Global Warming, and the Environment / Mark C. Henderson.
The book has received a positive review by David McCorquodale, co-chair of Green Pages, the US Green Party quarterly (http://www.gp.org/greenpages/index.php). See it an other information at the publisher's website:
<a href="http://wavesofthefuture.net/">Waves of the Future</a>
Keywords: <a href="http://wavesofthefuture.net/">eco-taxation strategies</a>, <a href="http://wavesofthefuture.net/">global warming solutions</a>
in the last 900,000 years, CO2 concentration has never exceeded 280 ppm, and that includes during the hottest of greenhouse phases. today, the average amount of CO2 in the atmosphere in the U.S. easily exceeds 380 ppm. the earth transitions from greenhouse to icehouse phases once every 100,000 years, (at least for the last 900,000 years). before 1.2 million years ago the transition was about 41,000 years (in tune with the earth's obliquity or 'axial tilt' periodicity, however no one really knows why or how this shift in transition periods happened). the concern with increasing climate has nothing to do with it being unnatural or anything of the sort, since it has been happening for millions upon millions of years. the concern lies in the rate at which it is happening. had a dramatic increase in CO2 like this been seen 10,000 years ago, one would have literally seen the fastest shift from an icehouse-greenhouse in earth's geologic history. we are currently experiencing the earth's 7th mass extinction, one which took no more than 150 years to propogate (in contrast to the tens of thousands of years it took for previous extinctions to ensue).
Reply | Report Abuse | Link to thisiron fertilization of the oceans is currently one of the most viable ways to directly sequester carbon from the atmosphere. the fertilization of iron (a mineral which is delivered to the oceans before every ice house due to glacial scraping against bedrock) increases the productivity of the phytoplankton which reside on the ocean surfaces. clearly, this is another risk entirely and of a different caliber. it isn't a matter of whether or not man 'can' or 'should' alter or 'better' nature for his or its benefit (clearly a huge issue in ecological & environmental ethics), simply that when man does try to alter nature he usually 'messes it up' one way or another. a great example of this is the attempt to control the infestation of russian olive trees or tamarisk in the west by introducing the salt cedar leaf beetle from asia. there are now two major infestations that are taking over floral and faunal ecosystems throughout the great basin and beyond.
a solution must be sought not just in humanity's ability to adapt technologically, but in behavior modification which emphasizes the recognition of regional biotas as a whole. this includes tending to local economy, self reliance regarding food provision, & the preservation of whatever wildlife we have left. these things may not reverse climate change per se, but they would certainly ease man's inevitable transition to being sustainable once again.
Our industrial revolution needs to strive towards "greener" production facilities... thus having less of a carbon imprint..

Reply | Report Abuse | Link to thisGreat to see realism about the climate debate, instead of 10 solutions there is just 1 that encompasses all solutions which is simple, transparent, and avoids regulations.
100% ENERGY TAX to replace all other taxes, corporate, national, personal, property, death, consumer taxes and any others you can dream up.
The ENERGY TAX would be implemented over a 5 year period replacing all the other taxes one by one and collected at source , for example at the well or pit head ,or quarry.
This tax would be based on the potential energy value of the substances and a single price put on these per unit of energy.
The collection of this tax would be simple and far easier to control against fraud and evasion.
To encourage the correct direction of reduced energy use, environmental good behavior, and social harmony, a system of rebates would be introduced.
These rebates would be to give families rewards for reducing population and staying together as a family unit and not requiring social handouts.
Rebates for environmental and energy conservation would be only temporary to encourage the correct direction of the corporate and personal way of life.
The real benefit would be to make energy the real debate in all parts of life and question the direction and the uses it is put to.
The capitalist system would remain in so far as it is necessary to have ambition, drive, and enthusiasm for the new way forward.
MONEY=ENERGY=CLIMATE CHANGE
This formula is simple and shows that it is the financial system that has to change and find new ways of running a smart economy with less money and subsequently less energy.
Money is only a tool by which we transfer energy from one form to another and pass energy from one person to another.
Money is also a store of potential energy that can be released when needed, with the purchase of goods, energy and labour.
Simple
Transparent
Easy to understand
Equal to all
Rebates and overall tax reduction
Theses are all the things politicians are asking for but due to personal greed and selfishness are not prepared to take the bold decisions necessary.
Obama is a breath of fresh air, but THIS is the real step needed to save civilization as we know it for our children, not to mention our grandchildren.

Massive investments in current technology will not help us enough. It is time to think better.
A CO2 reduction plan was envisaged during my M.Sc. in Environmental Technology, as a class-assignment in 1999-2000. It was a low tech plan which could easily be put into practice where the whole world could come to play. The plan offered a new dimension to carbon trade for businesses. The outline was as below-
Reply | Report Abuse | Link to thisFast-growing trees assimilate CO2 out of air fast (4 times faster than natural forests). We need to harvest these trees for their fast growing period in selected areas around the world. The harvest (dry hard wood is >50% carbon and very slow degrading; about 25% of fresh wood is carbon) will be put away into caves, empty mines and natural faults- thus putting away atmospheric CO2 safely and cheaply for a very long time. After all, thousands of years old similar fossilized trees we use (oil, coal and gas) cause air CO2 to rise. Why not put back some?
A Chinese saying is Catastrophe = Opportunity . Could we not witness the CO2 rise as an opportunity to store some energized Carbon (similar to currency?) for foreseeable future use? Businesses may choose to grow & bury calculated numbers of trees each year to compensate for their extra carbon emission need. This plan will help developing countries come to terms with the worlds Carbon Trade agreement where they can even keep the harvest for themselves. The plan allows a proportionate trade between businesses and the earth, which is only apt.
This act means no offense to tree-lovers, forest-lovers or nature lovers. Only newly grown, purposefully, commercially harvested trees will be used, leaving natural forests alone. Scientists will calculate the numbers of trees required each year and decide types of trees to harvest for total sustainability.
Desperate time calls for desperate measures. I know this is not The solution, but as an Environmental Technologist I believe it has the signature of being a substantial part of it.
Here I urge all Environmental Action Groups and scientists to commission the plan as good enough to counter any other CO2 reduction plan (if not better), and press worlds policymakers to acknowledge the same so that carbon traders may get this plan as a choice.
Unique Advantages of the Plan:
=======================
It's very easy to make armchair suggestions about what politicians and corporate conglomerates should do to stop global warming. It's much harder to make the commitment to set agressive personal goals (and achieve them) for what you will do to reduce your carbon footprint. We won't make any significant difference until we give up the American ideal of ease of lifestyle and the right to personal consumption. May I suggest grow your own food, keep a few chickens, walk to work, live in a smaller house, drive a smaller fuel efficient car - or better yet, use public transportation, shop at Goodwill, use recycled materials in home improvements, make Christmas gifts, compost yard and kitchen waste, collect rain water and install rain gardens on your property.

Reply | Report Abuse | Link to thisI would like to share my interest as one of the principals of Royal Wind, we have designed an Ocean Temperature Regulatory System using our revolutionary turbines to power cold water pumps. Our system is designed to pump large amounts of cold water to the surface of the ocean to create cold water thermoclines. We believe that widespread use of our system worldwide would result in a much desired global temperature regulation and reduction. The health of our oceans and the increased carbon sequestration are linked to global sustainability. We feel that without intervention the oceans are in danger of collapse. The health of our oceans is crucial to the maintenance of oxygen levels in the atmosphere. If the oceans die, we will struggle to survive. It’s all connected: ocean health, carbon sequestration, and global temperatures. Here’s the plan:
To install our ocean-current powered cold water pumps in strategic locations worldwide, creating cold water thermoclines, increasing the sequestration of anthropogenic carbon dioxide. Our system will also be used to build the polar icecap back to a more acceptable year-round base level which will also ensure the continued function of the thermohaline and of the North Atlantic drift. Our system will also be used to create cold water barriers to hurricanes. We can solve the Earth's problems with the right effort. We must if we plan to continue living on this Earth.
Erm.... now forgive me for pointing out the obvious... but even if every person on the planet disappeared tomorrow morning...along with our technology! wouldn't the surplus co2 still be there?

Brazil plays an important and unique role in climate change because it is one of the ten largest economies in the world and home to one of the greatest ecosystems and forests of the planet: the Amazon. Brazil is the eighth largest emitter of greenhouse gases and the third largest emitter in the developing world after China and India. Brazil suffers a lot from climate change, mainly because of the biologically diverse ecosystems. The tropical rain forest in the Amazon and the Pantanal wetland are of particular concern. Some studies show that, as temperatures rise, forest fires due to warmer, drier climate, increased deforestation and forest fragmentation could be more frequent. There is also concern that coral reefs along Brazilian coastlines could suffer from the effects of climate change, however, the studies about how climate change will affect agricultural productivity is not yet understood in detail. Another reason why Brazil’s climate change is important to the world’s climate change is Deforestation, which contributes to climate change first when forests are burnt, releasing greenhouse gases. When forests are cleared, carbon that was held in the soil is released as well, as carbon dioxide or methane.

• Bring clean and renewable energy to the world´s population using a technique called microsolar that converts sunlight into energy. This new method is cheaper and easier to apply than actual solar panels. The health benefits of living free from the toxic gasses, emitted by burning kerosene, are even greatest. Recent studies show that the earth receives more energy from the sun in just one hour than the world uses in a whole year. And that wo billion people in the world have no access to electricity. For most of them, solar power would be their cheapest electricity source, but they cannot afford it.
• Stop the use of fossil fuels, instead use plant-derived plastics, biodiesel, and wind and water power.
• Every year, 33 million acres of forests are cut down. Paper recycling and forest management—balancing the amount of wood taken out with the amount of new trees growing—could quickly eliminate this significant chunk of emissions.
• Paople actually spend more money on electricity to power devices when off than when on. Purchasing energy-efficient gadgets can also save both energy and money, plus it prevents more greenhouse gas emissions.

While this touches many GREAT points, some are currently impossible due to lazy americans. Others also have already been set into motion. Some of these points contradict each other.Biofuels can be made from used cooking oil but by not eating meat we are taking that away.

Reply | Report Abuse | Link to thisI personally burn wood to heat my home and at first I was concerned about my footprint. Two important points to consider here - first we only take dead trees, which also release C02 thru decomposition - second by removing these trees the forest is able to regrow faster.
Reply | Report Abuse | Link to thisHowever, there is the added bonus of planting. You can plant new trees, but you can replant oil :-) And given that young trees absorb more CO2 per pound then older trees (and of course dead trees), I believe we have effectively cut our footprint by a huge margin. Furthurmore, as time goes on, our replanted trees will continue to grow thus every year our footprint will become smaller and smaller and eventually become negative.
Wood burning is a sustainable alternative to home heating if and only if you follow certain practices. If you don't have any dead wood for example and you don't replant then you are going to quickly become a large net contributor.
Bottom line - each heating/cooking method should be considered on its own merits at the site in question - we must beware of broad sweeping statements related CO2. emmisions.

Reply | Report Abuse | Link to thisThe Climate debate has not moved at all since I last wrote , In fact it seems to have gone into reverse , with most governments evading doing anything mainly due to the current economic crisis.
THE CHANCE OF A LIFETIME is being missed, We need to make the goverments and everyone aware that the over heavy tax and regulatory regime we have cannot go on. It is top heavy , very expensive and open to fraud evasion and avoidance, as we have seen is the last few weeks on a grand international scale.
THE FIX is to simplify the tax system to one replacing all existing taxes with a single Natural Resource Tax , applied at source and thus avoids a lot of the problems we have with the current tax system which are similar the world over.
The World Bank and the IMF have to really get their act together and realise that the only way in which the climate can be brought under control is by economic and fiscal changes to the tax incentive systems that need to be introduced.
THE EFFECT would be a fundamental change in the way all designers, manufacturers, and consumers buy and use the natural resources embedded within all goods and services they consume and use.
The consumer would then be paying a more realistic price for the damage caused by the resources employed in the consumables they use, They would be in the driving seat of developments by the very purchases they make. Indeed,making a true and fair market economy for all concerned including the planet!

52 billion out of 3.6 trillion is 1.4%. That's significant.
