what can we do to stop global warming?

Question

i am having a project and have to write about global warming.please give me more details.

Answer 1

There are several things that can be done including reducing dependency on fossil fuels, recycling, becoming more energy efficient, offsetting carbon emissions and using technology to combat global warming.

ENERGY EFFICIENCY AT HOME
● When replacing appliances buy energy efficient ones.

● Turn off electrical appliances when not in use, don’t use the standby option.

● Use energy efficient light bulbs and switch off lights when not in use.

● Fit individual thermostats to radiators and don't heat rooms that aren't used.

● Insulate walls, lofts, hot water tanks and pipes.

● Turn your heating and air conditioning down, a small difference will be barely noticeable.

● Similarly, turn down water heating by a few degrees.

● Sign up to a green energy supplier, one that produces energy from renewable sources.

● Turn off heating and air-conditioning when the house is unoccupied.

● Wash full loads of clothes at a lower temperature; modern machines and detergents are just as effective at lower temperatures.

● Dry your clothes outdoors instead of in a tumble drier.

● Wash full loads in the dishwasher.

● Insulate your home and block draughts around doors and windows. In Europe this is free to many people.

● Consider installing a renewable energy system such as solar panels or a home wind turbine.

● Use rechargeable batteries; don’t leave rechargers on for longer than is needed (including mobile / cell-phones).

● Boil only as much water in the kettle as you need.

● Buy locally produced organic food where possible, there's less transportation and the farming methods are more environmentally friendly.

● Look where goods were manufactured and avoid buying those that have been flown or shipped long distances.

● Recycle and reuse as much as possible. Sign up with mail preferential services to stop junk mail.

● Avoid buying products with excessive packaging.

● Don’t have your fridge or freezer set lower than need to be, regularly defrost freezers, don’t put hot food into your fridge or freezer.

● If your fridge or freezer is over 15 years old then consider replacing it (check with local authority regarding disposal of old one).

● Work from home where possible.

● Eat less meat and dairy produce, farming produces large quantities of greenhouse gases.

ENERGY EFFICIENT TRAVELLING
For many people a substantial reduction in greenhouse gas emissions can be achieved by driving a more fuel-efficient vehicle. Each gallon of gasoline burned produces 10kg (20 pounds) of carbon dioxide. A motorist driving 15,000 miles a year in a vehicle that delivers 30mpg will produce 5000kg of carbon emissions whereas a vehicle returning 50mpg will produce 3000kg.

● Drive a fuel-efficient vehicle, if you have more than one vehicle then use the most economical one more often.

● Consider walking or cycling when going to work or taking the kids to schools, if you have to drive then consider car sharing.

● Use public transport where possible and consider taking a coach or train instead of using domestic flights.

● When replacing your vehicle look at diesel and liquid petroleum gas models.

● Combine multiple journeys into one and do your weekly shopping in a single trip.

● Stagger journeys where possible to avoid rush hour traffic and hold ups.

FUEL SAVING TIPS FOR DRIVERS
By driving carefully and keeping your vehicle in good condition you can save up to 30% on your fuel bills and cut greenhouse gas emissions at the same time. Below are some tips for increasing fuel efficiency.

● Avoid harsh braking, accelerate gently and drive at a steady speed.

● Keep tyres inflated to the correct pressure.

● Remove bike and ski racks when not in use, also remove detachable roof racks, luggage boxes etc.

● Carrying unnecessary weight wastes fuel, declutter your vehicle.

● Use the correct gear and use cruise control if your vehicle has it.

● Keep your vehicle regularly services.

● Turn the engine off when stopped or waiting.

CARBON OFFSETTING

Each of us leaves behind what is commonly referred to as a 'carbon footprint'. This is a measure of the environmental impact in terms of the amount of greenhouses gases produced; it is measured as the equivalent number of units of carbon dioxide. The global average is 5 tons per person per year, in developed nations the average is 11 tons and in the US it is 19 tons.

Carbon Offsetting is one way to reduce or eliminate your carbon footprint; in most cases this involves calculating your greenhouse gas emissions and planting trees so as to absorb an equivalent amount of carbon dioxide. Some websites where you can calculate your carbon footprint and purchase offsetting are:

GEOENGINEERING (CLIMATE ENGINEERING)
Ambitious schemes have been proposed that would manipulate our climate through geoengineering. These contentious schemes include constructing a giant sunscreen to block out some of the sun’s heat and artificial trees to extract carbon dioxide from the atmosphere. If these schemes are successful they could prevent global warming from getting worse and may be reverse the warming trend.

● Human Volcano
Volcanic eruptions emit large quantities of sulphur dioxide that blocks out some of the heat from the sun. Following the massive eruption of Mount Pinatubo in 1991 the average global temperature fell by 0.5°C. One proposal is to simulate natural volcanoes by firing pellets of sulphur into the upper atmosphere where the particles of sulphur will reflect back some of the solar radiation.

● Sulphur Blanket
Nobel Prize winner Professor Paul Crutzen has put forward a scheme which, like the Human Volcano, uses the principle of sulphur to block out some of the suns rays. Professor Crutzen's idea is to launch rockets into the stratosphere (10 to 50km above Earth's surface) and release one million tons of sulphur. This radical plan could have drawbacks including an increase in acid rain and damage to the ozone layer. At low levels sulphur dioxide is a toxic gas and in the past was emitted in large quantities from factories; ironically the Clean Air Acts, which reduced industrial pollution, removed much of the cooling sulphur dioxide from out atmosphere.

● Solar Mirrors
The US National Academy of Sciences has proposed a scheme that would involve positioning 55,000 gigantic mirrors in space. Each mirror would be 100 square kilometres in area and the effect would be to reflect some of the sun's heat energy back into space. For the time being neither the technology nor financial resources exist to enable such a scheme to go ahead.

● Global Sunshade
A similar scheme to the space mirrors idea involves placing a giant sunshade in orbit between the sun and Earth. British astronomer Roger Angel has proposed creating such a shade some 1.5 million miles from earth, at the point where gravity from the sun and the earth balance. His sunshade would consist of 16 trillion individual glass discs, each one microscopically thin and weighing just one gram. On board each disc would be a tiny camera, computer and solar sails allowing each disc to align itself so as to refract light from the sun just enough so it misses Earth. Angel proposes using electro magnetically propelled launches, each one delivering a million discs into space.

● Moving Earth
Perhaps the most ambitious of all schemes so far proposed is one to actually move planet Earth into a different orbit. It has been estimated that if Earth were 1.5 million miles further from the sun then the reduced heat energy received from the sun would compensate for anthropogenic global warming. Dr Ken Caldiera of Stanford University, an opponent of geoengineering, has calculated that the energy required to move the Earth this far would be the equivalent of 5 quadrillion hydrogen bombs (5,000,000,000,000,000).

● Cloud Seeding
Cloud seeding isn't a new concept and is one that has been tried with some success as a way of bringing rainfall to dry areas. One variation on this theme is to launch a fleet of self-propelled vessels to sail the world's oceans and spray a fine mist of seawater particles into the atmosphere. Marine Stratocumuli clouds form over much of the world's oceans and they're particularly effective at reflecting sunlight back into space. Professors John Latham and Stephen Salter from the UK believe that by increasing the number of such clouds, enough heat from the sun can be reflected back into space to offset global warming.

● Artificial Trees
A school science project provided the inspiration for Professor Klaus Lackner's concept of using artificial trees to extract carbon dioxide from the atmosphere. Air passes through the device and hydrogen sulphide absorbs carbon dioxide from the atmosphere, each 'tree' could remove 90,000 tons of carbon dioxide each year. The carbon dioxide would need to be permanently stored and the professor believes this could be achieved by drilling holes thousands of metres deep into porous rock beneath the oceans; the CO2 would be injected into the holes where it would permeate the surrounding rock.

● Phytoplankton
Phytoplankton are microscopic marine plants, invisible to the naked eye but visible from space as blooms of green ocean. Like all plants they photosynthesise - taking in carbon dioxide and releasing oxygen. Increasing the quantity of phytoplankton will result in more carbon dioxide being absorbed and when the plants die they sink to the ocean floor taking the carbon with them. Professor Ian Jones of Sydney University advocates that by using nitrogen rich urea to enrich parts of the oceans low in phytoplankton their numbers can be significantly increased.

● More About These Schemes
Some of these ideas formed part of a BBC documentary 'Five Ways To Save The World' you can read more about them on the BBC Website http://news.bbc.co.uk/1/hi/programmes/6298507.stm watch the programme trailer http://news.bbc.co.uk/player/nol/newsid_6360000/newsid_6364700/6364731.stm?bw=bb&mp=rm or watch the programme in full from Google Video http://video.google.com/videoplay?docid=286000425078890061

Answer 2

Global warming is one-half of the climatic cycle of warming and cooling.
The earth's mean temperature cycles around the freezing point of water.
This is a completely natural phenomenon which has been going on since there has been water on this planet. It is driven by the sun.
Our planet is currently emerging from a 'mini ice age', so is becoming warmer and may return to the point at which Greenland is again usable as farmland (as it has been in recorded history).
As the polar ice caps decrease, the amount of fresh water mixing with oceanic water will slow and perhaps stop the thermohaline cycle (the oceanic heat 'conveyor' which, among other things, keeps the U.S. east coast warm).
When this cycle slows/stops, the planet will cool again and begin to enter another ice age.
It's been happening for millions of years.
Humans did not cause it.
Humans cannot stop it.

Answer 3

The recent disasters around the world through severe weather conditions are enough evidence to spell out the fact that it will not be too long before mother nature starts flinging the serious and more cataclysmic stuff at us.

The dangers that we now face are horrendous to say the least and it is now far too late to stop global warming dead in its tracks. We could survive if global emergency action were to be taken immediately but I think that you know just as well as I do that things have gone too far and this planet's answer to the problem is to get rid of us = = =!!!!

Answer 4

Turn off all lights at Mall's at end of business day
Turn off all lights on Broad Way at midnight
Require all private Jets to use ethanol.
Require 10 trees per ac er in all developments,school and public buildings.
Put a carbon tax on all homes larger than 1,000sq feet per family member.
Put a carbon tax on all ceilings in public and private buildings that are over 9' high.
Ban all Styrofoam packing materials
I could suggest a dozen more but global warming is a false alarm. Only ten years ago they were predicting a new ice age. Has any one thought that the earths core may be over heated. We haven't had a volcano blow lately.
Scientist haven't uses any scientific rules to establish the certainty of global warming.It still remains a theory. Scientists don't get to vote if some thing is true it has to be proven by scientific methods.That has not been done.

Answer 5

Try doing honest research. You will find that the earth was warmer 2000 years ago than it is today, warm enough for wine grapes to be grown in England by the Romans who occupied it then.
Explain that the global warming hysteria is merely a political ploy being used by leftists to gain power. That is the truth, but since your teacher is probably a leftist your grade will be bad because you had the guts to be honest.
If all you care about is a good grade, tell your teacher that we will all burn up unless we obey AlGore and start using mercury containing compact fluorescent light bulbs and walk everywhere instead of driving.

Answer 6

Nothing climate change is a natural thing don`t believe the lies trying to stop Afriaca develop is a crime and murders millions. We are carbon based CO2 has nothing to do with global warming did you know Mars is also getting warmer I suggest watching the global warming swindle

Answer 7

Hey Kathie, did it occur to you when you wrote this question that tons of people ask the same thing EVERY DAY? You should check out one of those.

Also, come on. The only reason that scientists are talking about this so-called nonexistent "global warming" is because they have nothing else to talk about.

Answer 8

global warming can be stopped.. but for that all the developments n technologies in the world should also be stopped...which is not possible....can we live without a car,refrigerator,airconditioners,etc??its a big no!! we cant go back to stone age to prevent global warming..but yea i guess we can control our luxuries...n if everyone decides to live in a controlled manner then there can be some change..

there are two sides of a coin..if theres development..theres destruction coming up too......but in this world today where peolpe are moving sooo fast behind money n luxuries such things are left behind

Answer 9

I dont think we can. Ever if you took manmade factors out of the equation, the Earth is continually going through cycles of heating and cooling.

We would be better off investing in ways for our cities and societiy to exist in extreme climates.

I think the absolute number one issue that needs to be addressed is population control. It is like the problem mutiplyer. There are too many people and not enough resources, now that is the real inconvenient truth that's too much of a political hot potato for anyone to mention.

Answer 10

Theres no way to stop it, even without human intervention global warming would take place, we just are speeding it up.

Answer 11

Nothing. The planet is not warming. Al Gore is an IDIOT. If he is right then everyone that belives him should live in caves and eat dirt and drink rain water.
