does anybody know how we can prevent global warming?

Answer 1

Global warming is not something that we have 100% control over.

The geological record of the earth's temperature is very clear - for millions of years the earth has been going through cycles of warming and cooling. The Earth has been warming up since the end of the Pleistocene (about 10,000 years ago) due to complex influences that we don't completely understand, but they include the angle of the earth's rotational axis to the sun, the average distance to the sun, reflectance of the earth's surface, and atmospheric conditions including CO2 and dust.

Even if there were no humans on Earth with all the CO2 and pollution we are creating were removed, the earth would gradually becoem warmer without any human influence. Eventually, for reasons we don't understand, the Earth would then begin a cooling cycle again - the period of each cycle is irregular but they seem to last about 100,000 years.

So the best we can hope for is to help slow the RATE of global warming. I think the evidence is undeniable - the rate of global warming is unprecedented, due to the impact of 6 billion people in a very industrial society.

One of the contributors (and certainly the one we humans are responsible for) is the amount of C02 in the atmoshere. Fortunately, the Earth has a natural buffer that keeps CO2 levels in check - vegetation. As the CO2 levels increase, chloropyll-based green plants increase their rate of photosynthesis which converts CO2 to to O2. Also, forest fires have been a significant source of CO2 in the atmosphere for thousands of years. As CO2 levels increase and 02 levels decrease, forest fires will not burn as efficiently, meaning that nature already has ways of keeping atmospheric CO2 and O2 levels in balance.

But our consumption of fossil fuels (coal, oil, and gas) and even wood and peat, means that we are producing CO2 faster than nature can recover. On top of that, everything humans do creates heat and that needs to be dissipated in the earth's atmosphere.

With the technology we have today, probably the single most reasonable thing we can do to prevent the rate of global warming increasing so quickly is to replace all of our fossil fuel-powered electrical generating plants with nuclear plants.

The biggest opposition to nuclear plants seems to be the question of radioactive waste. Now here's a fact: a coal fired power plant (most of the world's electricity is produced from coal, esp China, Australia, and USA) produces more radiation than a nuclear power plant.

Of course the only way to completely eliminate our impact on the Earth's temperature is stop using all forms of energy, as every one of them creates heat and other side effects.

Answer 2

Reduce greenhouse gas emissions like CO2 and methane.

CO2 is 30% higher than it has been for 650,000 years. Methane is 130% greater. These are two of the main pollutants humans put into the atmosphere in excess, and they are two of the primary greenhouse gases.

Look at the 'hockeystick', which shows a dramatic warming since 1950 after a fairly stable climate for 1000 years. In fact, the 10 hottest years in recorded history have all happened since 1990, with 2005 being the hottest, and 2006 is shaping up to maybe break that record.

Until most of us know these facts, it will be hard to change things or prevent Global Warming.

Personally, you can use clean energy (wind, solar, etc.) when possible, drive less and efficiently, buy less processed products and meat (cows are the world's biggest methane producers), and elect people that care about this issue and won't be in bed with Big Energy.

Answer 3

CO2 has a lifetime of 100 years in the atmosphere. Meaning, even if we could immediately stop all emissions of greenhouse gases, the average global temperature would continue to increase for 100 years and the effects of that increase would take even longer to play out.

The only way to prevent global warming would be to somehow remove greenhouse gases from the atmosphere and store them somewhere (in the ocean or underground.) Planting trees does not really help because when a tree dies and decays, all the CO2 it captured during its lifetime is released again so there is no net effect on the amount of CO2 in the atmosphere.

Answer 4

Yes, there are many solutions to global warming.

Brute force answer: reduce the sunlight reaching the planet. This could be done with large reflecting panels placed in space near the L1 point, and controlling them by computer to open and close them for regulation.

Second brute force answer: pick a spot in the desert and get three to five very large hydrogen bombs. Detonate them. The ensuing cloud of dust and vapor will create a mini "nuclear autumn" and reflect some of the light from the sun back to space. If we use new bombs that we make, the fallout breaks down in a matter of days ad there is no residual radioactivity. Repeat as needed ever few years.

Another method: dump iron sulfate and soluble silica into the Antarctic seas where it causes a bloom of phytoplankton. These organisms absorb huge quantities of CO2 and also produce fish as a benefit. Phytoplankton ad diatoms are the food source for marine life.

Another method, but smaller: plant lots of trees and encourage seaweed farming. Most gas exchange occurs in the oceans, and 90% or more of that is within 500 km of the coastlines.

Here is a radical one: termites produce 10 times as much CO2 as oiur factories and power plants do. Locate and destroy some of these termites and we could regulate the CO2 easily. Most are in rain forests where trees are being cut down.

How about contrails? Jet exhaust reflects sunlight and the effect is measurable. If we purposefully inject water into the exhaust of jet engines, we can increase the volume of cloud cover and reduce the amount of sunlight heating in the atmosphere and on the ground.

Or, we could use reflectors on the rooftops of buildings instead of dark roofing material. This will reflect sunlight back to space, and it will also reduce the energy used to perform air conditioning.

There are literally hundreds of answers to this, but politicians and companies will drag their feet until they find a way to charge us for it and make money off it.

Answer 6

all americans have to pay double for their gas, just like anywhere in europe, that wil stop theym from driving big suv and hummers.
also, they (americans) would have to sign kyoto agreement on global warming, then u would have to start eating les meat as this is bread in south america where they cut down rainforrest to feed mc donald meat.
the turn of all yr pc and tv at night, eg.
not standby..
then u would have to stop the haarp project in alaska as this burns holes in the ionosphere.
wich does not sound like a good thing to me. and maybe then there is hope for humankind.
sorry to all the sad people that live in the us.
its not yr fould its that of yr corupt government and yr media that is keeping u dumb,
good luck from a sweet guy from holland (thats not the capital city of denmark)
ps,
usa contibutes for 1/3 of green house gass in the world!!

Answer 7

Yes i know. Aircondition the whole planet from the oil we are getting from Iraq.
