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. 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. Of course, reduction of carbon dioxide in the air will cool the Earth. Water vapor will also cool the Earth. We need increase evaporation of water. It is significantly cheaper then efforts to reduce greenhouse gases. 4. Sun is the best source of energy to evaporate water from growing trees, and not only will cool the air of Earth but also produce the cheapest, really “green” source of energy, which can be used in any time during hundreds of years. 5. White fresh snow reflects to space 75-95% of Sun radiation. White cars, houses, roads will do the same. Tim Flannery wrote that only new forests collect carbon also absorbing sunlight to grow and produce water vapor. Trees are the best and cheapest pumps in the world. They use Sun energy to evaporate huge amount of water. It is the cheapest way to cool the air of the Earth. Drop of rain on cloud level is the cleanest and the best solvent of carbon dioxide. Increasing of evaporation of water will do more to reduce carbon dioxide in the air than any attempt of conservation energy.

Article of Rachel Durfee is the best example that information about global warming in the world is wrong and only informs what politicians are thinking about it. That brings us to dangerous situations when even McCain, Obama and many others policymakers create more problems than solutions. Please read my attempt to reevaluate their information and bring back science. I found interesting that mass media speaking about global warming: 1. Forget that “ Forests contain much more carbon than does grass, and they also absorb more sunlight 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. 2. Mention only that greenhouse gases absorb heat in the atmosphere. 3. Absolutely misunderstand role of water vapor in cooling of the Earth. 4. 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. 5. Misunderstand possibility of conservation of energy and its limits. 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 always good direction but not enough.
