can we lessen global warming? if we can, how?

Question

it's for a research...

Answer 1

In the next 50 years or so , it's not very likely we're going to stop it, or even probably slow it down.

How can we reverse it - there are a couple of untried theories which might work.

1. It's painful but if we stop using fossil fuels - basically if we stopped using all oil/gas and coal, the planet would probably only warm another 3-7 degrees and global warming would start to reverse itself in about 300 to 500 years as the Earth soaked up th excess CO2.

2. Plant large equatorial forests, agressive desert reclaimation , aquifer restoration and then agressive reforestation of the Saharra and other equatorial deserts, Because of the location, and presumably an ample supply of water, trees will grow fast and use up CO2 in the process. This could not only stop but reverse global warming.

3. Mechanical CO2 carbon storage - it's being done today - it's just not very efficient, the Oil and Gas guys figured this out - go figure why it they like the idea of putting CO2 where the oil and gas used to be.

4. Sulphur cloud generation, create factories which create sulphur pollution (like in the 1970's) , this will create acid rain but will cool the planet - this was actually suggested recently as a "fix" .

5. Seed the oceans with diatomes - small organisms made of elaborate calcium-carbonate for skeletons, when they die they sink from the surface where they live and become sediment on the sea-floor. (This may not work but it's been suggested that it could work.)

6. Solar sheilding - large orbiting solar sheilds - big circular disks that would act like a sun-shield on the poles of the planet. They could be either opaque or translucent letting in light but not radiation. Many of these would be needed to create the needed cooling effects.

7. Do nothing - it's all good , in 50-60 years we run out of oil, in 50 or so years after that natural gas. coal won't run out for 300 years but you can't run a car or an airplane on coal so pretty much if you wait long enough, we'll run out of stuff to burn and then the global economy will more or less collapse due to environmental pressures.

Because unchecked use of fossil fuels will lead to some rather "unpleasant" circumstances. Like a few hundred million Asians who will need new places to live since water and food will become scarce where it is now plentiful (India and the Chinese lowlands).

The western 1/2 to 2/3rds of the US will become a serious desert when the summer water supplies/river sources (the Eastern Rocky Mountain watershed) starts to really dry up. Just ask the farmers in Montana about salt seep and water sharing nowadays.

Australia is already pretty much already screwed and becoming a much drier place, (voluntary (maybe someday manditory) water rationing, common multi-year long droughts, wildfires etc).

Pretty much because there will always be people who say it isn't so bad or isn't happening at all, or we don't need to spend money to fix that since it isn't a problem anyway

Personally ... I'm going to bet on #7 - I don't like it but it just seems more like Human nature - (see Humans!)

Answer 2

We can lessen the impact of global warming by reducing the amount of carbon dioxide and other green house gases (such as Methane) that we release into the atmosphere.

This can be achieved in a number of ways, including reduction of fossil fuel burning (gas, coal and oil), reduction of deforestation and number of cows (major producers of Methane).

If you want to help reduce the amount of electricity you use by installing energy efficient lightbulbs, turning off all appliances at night, not leaving them in standby, buy more energy efficient home appliances, use the bus instead of the car, walk when you can.

Check out the website for "An Inconvenient Truth" the recent fim from Al Gore for more information. If you can, rent the DVD and watch it. You won't regret it.

Answer 3

stop illegal logging, lessen legal logging, plant more trees everywhere, use some other stuffs as fuel...probably hydrogen because it's waste is environmental friendly...create a system that will lessen dust and smoke emmited from factories, scientist are to do more research on how to turn garbage and rubbish into power source...stuffs like that

Answer 4

If you walk and ride bikes, that helps. Join green clubs buy hybrid cars make green clubs write letters to congress. Watch the Inconvenient Truth to find out more

Answer 5

- Take public transport, cycle or walk
- Use cleaner energy, like Solar instead of coal
- Switch off electricity when not in use
- Plant more trees.
- Recycle, Reuse and reduce.

Answer 6

Plant more plants and some that live through the winter.

Answer 7

stop using products that contain CFC
