Are We to Blame For Global Warming?

Global warming is one of those topics that I still find myself wondering what to truly believe. Is our CO2 production really the culprit in the warming of the planet? Or are there some other larger influences at play here. I have a hard time believing mankind’s activities are solely to blame for any kind of climate change.

After all, CO2 is only one of many greenhouse gases that can affect the warming trend. Water vapor is by far the most abundant and effective at influencing the greenhouse problem. But I don’t see any kind of public concern over evaporation of water in any way at all. Okay, I realize that there is little or even nothing that can be done about that but the point is CO2 is just a tiny fraction of the greenhouse gases affecting our climate. So if water vapor is by far the largest greenhouse gas then why are we so obsessed by manmade CO2? Mankind’s ego.

We see a small trend in the planets temperature rising and of course we assume it must be what we are doing. I am truly pleased to see that we are taking an interest in reducing pollution from cars and industry but I really have my doubts about the connection to global warming at least in the significant way the media would like us to believe.

The media is sounding the alarm bell which of course sells more newspapers than reporting the less extreme predictions surrounding the warming trend. The weather models produced by scientists predict a reduction in the temperature differences between the poles and the equatorial regions. This will in fact reduce the number of violent tropical storms, as there will be less of a temperature discrepancy to stimulate them. Also the warming of the regions closer to the poles will allow agricultural pursuits in areas where it was not possible before. Food production would be able to rise accordingly. The alarmist media isn’t interested in those types of stories it seems.

The change in the world’s temperature is just that, change. There is irrefutable evidence that the temperature of the planet has and most likely will always be changing regardless of what we are doing. What are we so afraid of? Do the alarmists doubt mankind’s ability to adapt and cope with a few degrees of temperature change or even sea levels rising a meter or so? There will doubtless be hardships and even some displaced people in some regions but man has the ability to adapt and change. We have demonstrated this through the ages. I am confident that we will not only survive these changes but also learn to use them to our advantage.

I live in Canada and if you ask anyone living north of the temperate zone about rising temperatures the resounding response would be “bring it on, we could use a little global warming around here”. Life will improve greatly for huge numbers of the world’s population with a couple of degrees increase in the planet’s temperature. Migration to areas that were before considered uninhabitable by most will have a more moderate climate allowing for farming and other activities. You can’t sell newspapers with stories like that.

The scientific data indicates that 1998 was the warmest year on record. The planet has been cooling ever since. A quote from Dr. Oleg Sorokhtin of the Russian Academy of Natural Sciences “The earth is at the peak of one of its passing warm spells, It’ll start getting cold by 2012, and really, really cold around 2041″. So who are we to believe? A respected scientist or Al Gore who has made millions from his crusade for the planet and his questionable agenda and phony pseudo science.

If the planet is warming I can honestly say I hope so. We will get by and probably do well in the process. What really concerns me is the muzzling of real science in the debate. An objective media would go a long way in helping us all deal with the facts as they truly are. Focusing on the alarmist perspective only causes undue fear where none is warranted.

Is driving our SUV’s and minivans really the problem here? Or is our planet just going through another climate cycle like it has done so many times before? The only thing I know for sure is I can’t count on the media to provide the answers.

Gasification Sees a New Dawn

If you search for gasification and terms like “wood stove” on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.

So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?

What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.

This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.

Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.

Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.

These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.

Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.

Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.

Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.

Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.

Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.

The Pine Beetle in Canada

For some time now, the extremely destructive Pine Beetle ( Dendroctonus ponderosae ) is ravaging huge areas of Canada’s forestlands and its destruction is so virulent, that it is leaving massive and easily visible scars across otherwise green foliage landscapes. In numerous areas where the pine beetle is active, various solutions for its eradication have been tried and some of these in themselves, are so toxic in nature that they would normally be classed as being a larger risk than the beetle they are attempting to destroy.

These beetles have an average life span of about one year and generally, their eggs are laid through the bark of a tree where they develop into larvae that stay under the bark all through the winter months. During the spring the larvae continue to feed under the bark and then they will change into pupae during the months of June and July. During the rest of the summer and into fall, the new adult pine beetles leave the infested tree through emergence holes they create and after drying themselves in the warm sunshine, they take off to mate and commence a new cycle by laying the next generation’s eggs under the bark of new trees. 

During the time they remain under the bark of a tree, they are known to transmit a fungus type substance that stains the sapwood of the tree a blue colour. Other than discoloration, this blue colouring appears to have no adverse affects on the actual structural integrity of the tree. However, we must not forget that the damage has already been done and like a rolling snowball, it gather momentum and range of spread with each summer that comes. These beetles prefer mature trees such as lodge pole pines which are considered mature after eighty years of growth and in the Province of British Columbia, current statistics show that there are three times more mature lodge pole pines than they had over ninety years ago. Hot and dry summers make the trees more stressed and thus more susceptible to attack and infestation by this ravenous little creature. Trees which have been attacked will turn red roughly one year after the infestation and then, between one and two years later the affected trees will turn grey and all of their needles will fall off.

Another interesting fact about these little guys is they do not like it too cold! Their eggs, larvae and pupae are very susceptible to very cold temperatures and if these temperatures remain below minus 35 Celsius for a prolonged period of maybe a week, then this will kill off the eggs, larvae, pupae and generally sizeable portions of the beetle population in that area of cold weather. This being said, unless we suddenly enter the start of a new ice age all across Canada, these sporadic cold spells are unfortunately not enough to rid us of this continually spreading plague of destruction.   Yes, there are action plans prepared and in place and yes, the Canadian Ministry of Forests and Range are really trying to get to grips with finding a solution to this costly problem but to date, the efforts and methodology being used has had little or no effect on the overall problem.

The good news is that an answer to this massive problem does exist and better still, it is an answer, which consists of no chemicals, no toxins, no poisons and no danger to either the forest or to the people who would apply the solution. This answer can be found right now in the form of a golden all natural organic fluid formulated around a cedar oil base. This fluid can totally eradicate the pine beetle and a few other nasty insects at the same time. It is not cheap but then again it is not as expensive as some of the other treatment that have been tried. It is non hazardous and will not harm the environment in any way and it is here and available right now. Unfortunately, for now it appears that here it must stay as the Ministry of Forests and Range are continuing their quest with what they feel they know best. Maybe someday, hopefully soon, they will realize that we can defeat this natural pest by using a totally natural substance.

Green and Clean Computing

Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects.

The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally.

There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life.

The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary.

The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance.

Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment.

Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.

The Queen of Re-Use: not just hand me downs

If I gave my family questionable marks on its efforts to reduce, I admit that when it comes to re-using I am the Queen. When I was a teenager there was a song, ‘I was country, when country wasn’t cool.’ Well, I was re-using back when it was called hand-me-downs and everyone looked down on you for wearing them. Honestly though, I can remember being about five and having a distant second cousin visit. She had brought a bag of clothes that had been her daughter’s, who had died. That may sound morbid, but I think my smiles and thanks for the ‘new’ clothes may have helped to let go of not only the clothes, but a bit of her grief as well.

If you were to look in my three year old’s playroom, most of the toys you would see have been given to her second-hand from friends, purchased at charity shops or even salvaged from the bin…including her wonderful Little Tikes kitchen centre.

But my re-using does not stop there, if you open my kitchen cabinets you will see stacks of old containers that once held spread, cottage cheese or something else. With the exception of the air-tight sealing bowls that my husband uses to transport his food to work each day, we do not purchase or use Tupperware, Serv-rite or any other type of plastic wear. And those plastic containers that once housed my produce such as strawberries, blueberries and peaches are now being re-used as pots for my spring seedlings. I also have a cabinet full of sauce jars that I am looking for ideas on how best to re-use. I have already filled several with nuts, bolts, nails and the like. But even after getting organised myself, I just can’t bring myself to throw these into the recycle bag when I know that they are perfectly re-usable as they are. As I mentioned yesterday, I re-use the few plastic bags we get from quick trips to the corner store for bin liners in the bathrooms.

I have even taken to re-using my daughter’s Fruit Shoot bottles by refilling them with concentrate fruit and water. Of course, a tad of a warning on this one: do not freeze plastic bottles as it can cause a cancer causing chemical to leach into the drinks. So I always replace the bottles after a few uses just to be safe. But then they can go into the recycle bag (but that is tomorrow’s topic).

Even dinner last night was re-used food; better known as left-overs. Anyone that reads my blog knows I have dozens (hundreds?) of ideas for re-using food as soups, smoothies, casseroles, stir-fries or just re-heated and served. I call this creative cooking and make it a staple of not only our family’s diet, but of my blog as well: offering recipes to my readers.

I think one of the most beautiful examples of re-using is the folk-art form of quilting. Not only can worn-out old clothes be turned into colourful quilts, but they can tell a story: our history. I have also heard of people braiding old cloth to make rugs as well. Last year at the Green Show, I bought my daughter the cutest little purse made from old plastic juice boxes by a women’s cooperative in the developing world.

Thinking back to my own childhood and the used toys and clothes that I was blessed to enjoy, I am glad that it has become the ‘cool’ thing to re-use. Not only do these items still have good life left in them, but they remind us that we, ourselves, re-use life’s lessons to improve our world. So next time before you toss that item into the bin or even the recycle bag, stop and ask yourself could it be re-used instead: perhaps that wine bottle would look nice on a table with a candle or a few flowers or could that old t-shirt be cut into squares and used instead of paper towels or how about making puppets with old and mismatched socks. The ideas are limitless…I hope you will share your favourites with me as well.
