I will post your opinion or question on this page and Michel Ioffe will give his answer if it’s a question or give his comment it it’s an opinion just below of yours.
About global warming.
Our efforts in fighting global warming can be more productive if we will reexamine what we are writing and speaking about it. I found interesting that:
1. Very often mass media changed carbon dioxide equivalent of all greenhouse gases only on carbon dioxide.
Forget that “Forests contain much more carbon than does grass, and they also absorb more sunlight (having different albedo) and produce more water vapor, which affects cloud formation”. Mature forests don’t take in much CO2 for they are in balance, releasing CO2 as old vegetation rots, then absorbing it as new grows. For these reasons the world largest forests-the coniferous forests of Siberia and Canada, and the tropical rainforests are not good carbon sinks, but new vigorously forests are.”
3. Mass media mention only that greenhouse gases absorb heat in the atmosphere. More important processes that cool the atmosphere are completely ignored by mass media.
Absolutely misunderstand role of water vapor in cooling of the Earth, despite that it is also greenhouse gas.
Misunderstand that any source of energy – nuclear, wind, hydro, solar cells, hydrogen, geothermal in condition when greenhouse gases anyway will increased by others processes will heat the atmosphere as heat pollutant.
Misunderstand possibility of conservation of energy and its limits.
If we will look carefully on result of these misunderstanding we will found dangerous situation when high respectful authors asking us to do what in reality will bring more harm than good things.
“It’s not just carbon…
A single-minded focus on greenhouse gas emissions is the wrong way to fix our environmental problems.” (Alex Steffen, Wired, June 2008).
Let look in Statistical Abstract of the United States, 2007 (126 Edition) page 577, table 897.
“Energy consumption by End-Use sector in quadrillion British thermal Unit (BTU).
Total-1970 year –67.84 (67,840,000,000,000,000)---2004 year-99.74
Residential --------1970 year –22.11 2004 year-38.6
and commercial
Industrial-----------1970 year –29.64 2004 year –33.25
Transportation-----1970 year –16.10 2004 year –27.79.
Our consumption of energy in the 2004 compares with 1970 almost double in residential and commercial, and transportation. Industrial energy did not grow in the same rate only because most industrial production moved to China and others developed countries.
Without any doubt to live better we need more energy.
In the world media idea of conservation of energy by increasing efficiency of all equipment and appliances prevail.
If we will increase efficiency of our motors, equipment, appliances, home heating and cooling systems, etc. from average 25% right now to impossible 100% it will mean only that four times more people will live on the same level as middle class in USA today. It is not enough even for USA population, not mention all countries in the world.
Conservation of energy is not a solution. It is always good direction but not enough.
Nuclear energy, geothermal energy, wind energy, solar cell energy even if they will emit zero carbon dioxide in the atmosphere of the Earth (everyone knew that it is not true) still will heat air in situation where greenhouse gases in the air will be increased anyway by others processes.
It is possible to use these energy sources, but it is not true that solutions to fight global warming are nuclear, geothermal, wind, solar cell, hydrogen cell or many others or very expensive or not so effective sources of energy.
Nuclear and geothermal source of energy will additionally to Sun heat air of the Earth.
Wind and solar cells energy are very expensive and need batteries to store their energy in times when we haven’t wind or Sun.
If we still want to use them it is better for windmills directly found job, perhaps pump water from places where we have flooding to places where we need water. This will reduce significantly price for wind energy (we no need devices to change kinetic energy of the wind to electrical energy, electrical transformers, lines, motors etc). It also will increase efficiency of windmills. In this case it is not so important timing of pumping water.
Solar energy is better to use to grow vegetables, corn, wheat etc. The best way to use Sun energy is to grow forests. Trees are the champion in the world and grow faster than any others plants. They collect Sun energy during hundreds of years. Wood from the trees can be the cheapest source of energy for power plants. All emissions from these power plants can be without any harm sequestrated back to the land by water and will be the best nutrition to grow the same trees.
Instead of harvesting every year corn, grass etc for ethanol production we will harvest wood for electricity production from forest in area at least 100 times less than in case of harvesting grass, corn etc for liquid fuel. It will be the closest to customer source of energy and therefore cheaper than coal. Coal right now the cheapest source of electrical energy.
It takes one ton of coal to generate an average of 2500 KWH of electricity.
It takes less than 1.6 ton of wood to generate the same amount of energy.
By David Fleming, April 2006:
“It takes a lot of fossil energy to mine uranium, and then to extract and prepare the right isotope for use in a nuclear reactor. It takes even more fossil energy to build the reactor, and, when its life is over, to decommission it and look after its radioactive waste.
As a result, with current technology, there is only a limited amount of uranium ore in the world that is rich enough to allow more energy to be produced by the whole nuclear process than the process itself consumes. This amount of ore might be enough to supply the world's total current electricity demand for about six years.
Moreover, because of the amount of fossil fuel and fluorine used in the enrichment process, significant quantities of greenhouse gases are released. As a result, nuclear energy is by no means a 'climate-friendly' technology”.

http://www.feasta.org/documents/energy/nuclear_power.htm”
Many scientists can confront David Fleming opinion, but they still need to agree that nuclear source of energy will additionally heat the air and will work as heat pollutant.
As you can read in Tim Flannery book “The Weather Makers,” 2006:
“Forests contain much more carbon than does grass, and they also absorb more sunlight (having different albedo) and produce more water vapor, which affects cloud formation”.
“Mature forests don’t take in much CO2 for they are in balance, releasing CO2 as old vegetation rots, then absorbing it as new grows. For these reasons the world largest forests-the coniferous forests of Siberia and Canada, and the tropical rainforests are not good carbon sinks, but new vigorously forests are.”
If we will follow Tim Flannery, we can say, that all one-year vegetation wills rots during one year. In nature they are rots slowly, providing during vegetation period nutrition for new growing plants. Together with others vegetation on the Earth they create balance during millions years, when in air we had 280 parts per million of carbon dioxide.
Growing population, industrial revolution changed this balance. It is inevitable: we harvest food from almost all land in every state and bring it to huge cities, where rots of waste haven’t enough plants to take back carbon dioxide.
If we will grow corn, grass, etc. for ethanol or others so called “green sources of energy” we will bring to ethanol production place every year increasing amount of plants from which we extracting ethanol. We need energy to plant and harvest these sources. It will increase amount of carbon dioxide in the air despite our good intentions. “Green sources of energy” is a disaster for environment and as soon we will agree on that we will not spend money and efforts in wrong directions. Green sources of energy will not save civilization from global warming.
The same situation we have with efficiency of our production, transportation system, our homes, appliances and other needs of civilization. Demand for better living increased faster than our ability to increase efficiency of our equipment.
It is normal to have new balance of greenhouse gases in the nature.
Needs for energy in the world, as amount of greenhouse gases in air will grow despite all good resolutions and all inventions.
We intensified style of our life. We need to intensify process of cooling air in the Earth.
From Earth Science, Baron’s Educational Series, Inc, 2001
“Solar radiation reaches the upper atmosphere at a fairly constant rate of about 200
Kilocalories per minute/square meter. About 1/3 of this radiation is reflected back into space mostly by clouds. Ozone, carbon dioxide, and water vapor in the atmosphere absorb or reflect most of Earth’s infrared radiation; the rest go through the atmosphere and out into space. Solar energy reflected back into space by thick clouds – 75-90%, thin clouds – 30-50%, water – 10%, grassy field - 10-30%, fresh snow – 75-95%, forest – 3-10%…
The atmosphere consists mostly of gases, but also contains water, ice, dust and others particles. In dry air we have 78% of Nitrogen, 21% of Oxygen, almost 1% of Argon. In air we have traces of other gases: Neon, Helium, Krypton, Xenon, Hydrogen, Ozone, Carbon Dioxide, Nitrogen Oxide, Methane.
Molecular mass of N2 = 28, of O2 = 32, of H2O = 18. Since the lighter water molecules displace heavier air pressure decreases as humidity increases. HUMIDITY UP, AIR PRESSURE DOWN, HUMIDITY DOWN, AIR PRESSURE UP
Wind blow from region of high air pressure to region of low air pressure as in sea breeze, land breeze.
Climate influences a REGION’S NATURAL VEGETATION.
The roots of plants absorb water that has seeped into the soil. Then the water is transported to their leaves, and released back to the atmosphere, as water vapor. Each day an estimated 15 trillion litters of water in the form of rain or snow fall on the United States alone.
The atmosphere which now has a total mass about 5,000 trillion tons is held in place by Earth’s gravity and extend several hundreds kilometers into space.
A number of factors control the amount of solar energy that an area absorbs or reflects including the angle at which incoming solar radiation-insolation-strikes the surface, the length of time each day, that insolation is received, and a nature of the surface.
Most insolation passes right through the atmosphere to Earth surface, where it is absorbed and changed into form of energy that atmosphere can absorb by conduction, convection and radiation.
Most of the energy radiated by Earth’s surface is infrared radiation. Greenhouse gases absorb or reflect most of Earth’s infrared radiation; the rest goes through the atmosphere and out into a space.
Thus short-wavelength can readily enter the atmosphere, but long-wavelength cannot readily escape a phenomenon known as greenhouse effect.”
What are the most important lessons from these two books?
1. Clouds reflect huge parts of solar energy back to space: thick clouds-75-90%, thin clouds-30-50%;
2. Forests contain much more carbon than does grass and they also absorb more sunlight and produce more water vapor, which affect cloud formation.
3. Water vapor is one of the lightest gases and has tendency to go up to cloud level. Water has another properties it takes a lot of energy to evaporate water. To evaporate one kg of water we need 339 kcal of heat. We need one kcal to increase temperature of 1 kg of water on 1ºC. Evaporation of water will cool air temperature. Despite that water vapor is greenhouse gas, it tendency to go up bring them on cloud level, where distances between molecules bigger and heat will go to space more easily than on ground level. No others greenhouse gases have these properties. Drop of rain when falling down partially evaporated and go back to cloud level, but more important they dissolve a lot of carbon dioxide and others “heavy” greenhouse gases from the air and soil and feed all plants on the Earth.
4. Of course, reduction of carbon dioxide in the air will cool the Earth. Water vapor will produce the same effects of cooling the Earth. We need increase evaporation of water. It is significantly cheaper then efforts to reduce greenhouse gases. Drops of rain at the same time will clean air from carbon dioxide better than any efforts of conservation of energy.
5. Sun is the best source of energy to evaporate water, to grow trees, to produce the cheapest, really “green” source of energy, which can be used in any time during hundreds of years.
6. White fresh snow reflects to space 75-95% of Sun radiation. White cars, houses, roads will do the same.
Let go back to Wired, June 2008
“Farm the forests (MP-I hope I do not make mistake that it is Matt Power)
Ronald Reagan’s infamous claim that “trees cause more pollution than automobiles” contained a grain of truth…Canadian forests actually gives up more carbon from decomposing woods than they luck down in new growth.”
It is OK for President Reagan to use for political purposes a good slogan. It is not OK for Canadian Scientists to be blind by politicians. Carbon dioxide is not only one player in cooling and heating air of the Earth. Canadian forests evaporate a lot of water. Scientists even if they asked about carbon dioxide in Canadian forests need to mention cooling the Earth’s air by water vapor.
Unfortunately I do not see in mass media voice of scientists when United Nation Secretary-General Ban-Ki-Moon claim (UN Chronicle, Volume XLIV #2, June 2007) “Global greenhouse gas emissions have to start to come down. Carbon trading is but one weapon in our arsenal, even if it does range among the most effective policy solutions. New technologies, energy conservation, forestry projects and renewable fuels, as well as private markets, must be part of long-term policy solution.”
Al Gore “The assault on reason”, 2007: “The energy crisis and the climate crisis are inextricably linked-both in their causes and in their solution. In order to deal with the planetary emergency caused by the rapid accumulation of man maid carbon dioxide (CO2) in the Earth’s atmosphere, we must quickly address its principal cause-which is our civilization’s tragic overdependence on burning massive quantities of carbon based fuel.”
The same mistakes make all our candidates for President and many others politicians in the world.

“Save the Planet: Vote Smart
By THOMAS L. FRIEDMAN
Published: October 21, 2007
…So if you want to be a green college kid or a green adult, don’t fool yourself: You can change lights. You can change cars. But if you don’t change leaders, your actions are nothing more than an expression of, as Dick Cheney would say, “Personal virtue.”
Are you serious, Mr. Friedman, those leaders who will ask to change lights and cars on hybrid will save the Earth?
Unfortunately Barack Obama and John McCain about global warming offer close solutions.
