If everyone planted a tree, say tomorrow, what would the impact be, if any, on global warming?

I think it would help in your theory,due to more greenhouse gasses would be assimilated by more trees.\n\npart of the problem with global warming is that much of the planets eco systems are being destroyed without being replendished (south america tree harvesting)

It depends totally on the type of tree, outside temperature, humidity, etc.

Global warming is in theory reversable,but it will mean global co operation between all countries ,and taking into account human nature and the world politics ,it is unlikely that this will happen,At least not untill we are all in the middle of planetary disastres and it becomes a battle for the survival of humanity every where.\n\nSOLUTIONS\nif you want to help the planet ,plant a tree every week ,if everyone on the planet did we we would be able to reverse the destructive processes\n\nreduce carbon emisions,and they are already working on that by alternative forms of energy and regulations on carbon producing materials,aerosol cans,burning rubbish,industrial chimneys,powerplants etc.\n\nthe capture of carbon and the production of water and assist the aquiferous manta.the world bank pays large subsidies for reforrestation to capture carbon and the best tree for this is the Pawlonia \n\nWaterharvesting projects ,such as millions of small dams.to redirect over ground waterflows from the rains into the ground to supply subteranian water supplies.\n\nthe protection of existing forrests.\n\nstop building more highways,urban planning to include vegetation \n\nstop building cities encourage people to return to the land to conduct their business from there which now has become possible thanks to the internet.\n\neducation to motivate people to auto sufficiency by building more home food gardens.\n\neducation on environmental awareness\n\neducation on family planning to combat overpopulation which contributs to 70 million people each year which puts more presure on farmers tom grow more food \n\nAgricultural education and improvements to follow the principals or sustainability and soil management.\n\nmore environmental or land design, to prevent bush fires,such as--fire breaks \n\nregulations and control for public behaviour on polution and limiting the use of fossilfuel \n\nalternative effeciant public transport to discourage the use of the internal conbustion engine\n\nrecicling wastes,\n\nlimit water use

Both. As non-sustainable practices begin to have more and more consequences we will be forced to find alternatives, and often will not find the alternative in time to prevent significant suffering. In some areas we may have enough foresight to change before the impact is felt. I am encouraged to see more and more wind power being installed, both on land and on ocean based platforms, but at the same time I am discouraged to see people choosing to drive large SUV's which will have a negative impact on the future. In some areas reforestation is taking place, where 100 years ago there was deforestation. This is encouraging and is simply the result of changing economic use. I have also been encouraged to see negative population growth in the most industrialized countries; this suggests the present stresses on the planet may be relieved.

It really sucks.  I just watched a report on 60 Minutes about this subject and we are in deep trouble.  They showed a picture of the arctic in 1979 and one just taken six months ago.  It is unbelievable how much ice has melted in just 26 years.  The most noted authority on this catastrophe said that even if we were to stop putting greenhouse gases into our atmosphere, it wouldn't change the fact that our global temperature will still rise.  It probably wouldn't rise quite as fast, but it will still happen because of all the gases we have already emitted.  We can only sove this problem collectively as a human race and not separately as nations.

In the near future, scientists preidct of another Ice Age, followed by another supercontinent wear every continent comes together. Global warming would be temporary. Then, plants would die off, followed by the animals. This is because of teh growing sun and the heat created by it. Daily average temperatues would reach 100-35 degrees farenheit. Mitochondria stops working at 125-130 degrees farenheit. Thus, eukaryotic cells would die off and the earth would be left with bacteria-prokaryotic cells. Soon the heat of the sun would evaporate all of the oceans and only the hardiest bacteria would live, close to the Pre-Cambrian days. The surface of the earth would be so hot that it would melt, and earth would be swallowed by the expanding red giant sun. Before any of this happen, every 100 million years, a meteor larger than the one of the K/T impact that wiped out the dinos could hit us and kill everything except fot bacteria and another Ice Age would occur. Basically, the future represents the beginning of life on earth. bacteria-eukaryotic cells-higher animals-eukaryotic cells-and back to bacteria-no life.

talk about global warming\nits a huge topic that will be more than enough to fill up 10 pgs\ntheres a lot to be researched too, so prepare for lots of work\nstuff like causes, preventions, consequences, proof\nresearch into Kyoto Accord, greenhouse gases, ocean currents, recent appearances of hurricanes (hurricanes build on warm air, and the temperature has been rising in the past few decades), car emissions, melting ice caps, change in migration of animals, stuff like that

Global warming is the theory that the Earth's atmosphere and oceans are getting warmer due to pollution and other environmental factors induced by humans.\n\nSome of the factors include burning fossil fuels (oil) and deforrestation (trees remove carbon dioxide from the atmosphere).\n\nThere's discussion that if the effects of global warming aren't counteracted, ice caps will melt, sea levels will rise, and weather patterns could be altered. \n\nLow-lying coastal cities such as Bangladesh or New Orleans could be wiped out within the next 100 years as sea levels rise. Weather patterns could be altered, bringing drought to areas that used to have lots of rain, and rain to areas that used to be arid.\n\nRead any of the sources below, and you'll find more information about the causes and potential effects. It's definitely something that shouldn't be ignored.

Global warming....

Global warming can occur from a variety of causes, both natural and human induced. In common usage, "global warming" often refers to the warming that can occur as a result of increased emissions of greenhouse gases from human activities. See climate change, greenhouse effect, enhanced greenhouse effect, radiative forcing, troposphere.\n\n\nSource: 2006 U.S. Inventory of Greenhouse Gas Emissions and Sinks: Fast Facts (PDF, 2 pp., 220 KB, About PDF)\nGlobal Warming Potential (GWP)\nGlobal Warming Potential (GWP) is defined as the cumulative radiative forcing effects of a gas over a specified time horizon resulting from the emission of a unit mass of gas relative to a reference gas. The GWP-weighted emissions of direct greenhouse gases in the U.S. Inventory are presented in terms of equivalent emissions of carbon dioxide (CO2), using units of teragrams of carbon dioxide equivalents (Tg CO2 Eq.).\n\nConversion: Tg = 109 kg = 106 metric tons = 1 million metric tons\n\nThe molecular weight of carbon is 12, and the molecular weight of oxygen is 16; therefore, the molecular weight of CO2 is 44 (i.e., 12+[16 x 2]), as compared to 12 for carbon alone. Thus, carbon comprises 12/44ths of carbon dioxide by weight.\n\nSee radiative forcing, carbon dioxide equivalent.\n\nGreenhouse Effect\nTrapping and build-up of heat in the atmosphere (troposphere) near the Earth’s surface. Some of the heat flowing back toward space from the Earth's surface is absorbed by water vapor, carbon dioxide, ozone, and several other gases in the atmosphere and then reradiated back toward the Earth’s surface. If the atmospheric concentrations of these greenhouse gases rise, the average temperature of the lower atmosphere will gradually increase. See greenhouse gas, anthropogenic, climate, global warming.7\n\nGreenhouse Gas (GHG)\nAny gas that absorbs infrared radiation in the atmosphere. Greenhouse gases include, but are not limited to, water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), ozone (O3 ), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). See carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons, hydrochlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride.7\n\n\n\n\ngreenhouse effect  a warming process that balances Earth's cooling processes and helps maintain an average global temperature of approximately 60 degrees Fahrenheit. During this process, sunlight enters Earths atmosphere as short wave radiation. The radiation is absorbed by Earth's surface. The planet becomes heated and emits long wave radiation toward the atmosphere. In the atmosphere, some of the long wave radiation is absorbed by certain gases called greenhouse gases.  Each molecule of greenhouse gas becomes energized and emits heat energy in all directions.  By radiating heat energy toward Earth , greenhouse gases increase Earth's temperature. Note that the warming mechanism for the "greenhouse effect" is NOT exactly the same as the warming mechanism of greenhouse walls. While greenhouse gases absorb long wave radiation then emit heat energy it in all directions, greenhouse walls physically trap heat inside of greenhouses and prevent it from escaping to the atmosphere.\n\ngreenhouse gases  certain gases in the Earth's atmosphere that absorb some of the outgoing long wave radiation, or heat energy (see greenhouse effect). These gases include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

well they say in 2050 about 3% of species will die from the global warming, and about the same with plant species. probably gas will cost 20.00 a gallon lol. and more and more cars and trucks will not be running off of gas. which i hope actually will be true! and ill be 40 around that time wow!

I'd hug the tree. The tree needs to be loved too and we know that Republicans only hug Oil Cans. I am a proud Environmentalist that cares more about the Earth than making money to cut more trees down to own several houses around the Country. Lord knows what will happen to the habitat and balance of nature if they drill in Alaska. I wonder if there are really planning on sending all the animals to live on the moon instead of man !
521085
Not enough.  In the past 10 years we have cut down 64 million more trees than we have planted.  We should all be planting a tree!

Yes, and the bigger the thing we do, the bigger the impact. Our ecosystem means the whole of everything that exists around us. We strip mine, we pour chemicals and heated water into waterways and oceans, we trap and kill animals to extinctions, we pump oil out of the ground and burn it letting off a chemical reaction into the atmosphere, we have had nuclear accidents that have impacted the land and air for HUNDREDS of years. Iceland is melting.\n\nWe, meaning all humans, have an incredible impact on the ecosystem that we share with all life on earth.\n\nBut then again, the flapping of a butterflies wing has an effect on the ecosytem.

There is a great PDF file that is listed below from the EPA (Environmental Protection Agency) that may be useful to you.  It explains that little things may have a huge impact on global warming if they are widely accepted.  Recycling, fuel-smart cars, solar power, planting trees are all ways of improving the environment and reducing the impact of global warming.

Exactly none. There is a finite amount of energy stored on the planet in the form of fossil fuels. Burning it releases this energy. You cannot add more. There has been heat RELEASED by the burning of fossil fuels onthe planet, which many people believe causes global warming. The only heat energy added to the planet is solar energy.

No but it would affect existence on the planet! There is a delicate balance to be maintained and if polar ice caps melted, this balance would be tipped over.  You can certainly expect weird weather.
