What are the solutions of global warming?

Question

i need it for a project

Answer 1

Global warming would go away if you got rid of the media and the pseudo-scientist alarmists. Use this and get an "A".

Answer 2

A liberal once told me that it would be good if all people died.
In reality, time will cure "global warming", and we should not change anything we are doing to help "solve the problem". Yes, we should reduce real pollution, but CO2 is not pollution, it is necessary for plants to live, and the more CO2 in the air, the better for the trees.
The earth naturally goes through warming and cooling cycles, and in the 1970s environmentalists were screaming that people were causing another ice age and we would all freeze. Then the cooling cycle stopped and the earth started warming again, so they changed their story by making up different lies.
If you report the truth, you might get a bad grade because your teacher is probably a liberal who hates America and is trying to make you hate America. When you write your report you must decide whether honesty or a good grade is more important to you.

Answer 3

If you want TRUTH, here it is:
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 4

Man has no solution....since the sun radiates heat in a random manner and varies constantly the earth is heated and cooled in cycles just as other planets are. It has been happening for thousands of years and will continue in spite of human activity.

Answer 5

Global warming is a scam . Gore is making million's from the poor and ignorant.

Answer 6

First of all, I think we should convince people to use public transport which would mean less cars which would reduce the amont of exhaust fumes in air
Fuel-efficient vehicles. Renewable energy. Protecting threatened forests. These common sense solutions won't only reduce global warming, many will save us money and create new business opportunities

Answer 7

Kill off most of the people living on Earth (about 95% should do it.

Nothing else will actually change the increasing CO2 levels, it will only slow it down.

Answer 8

The final chance for survival of mankind…..
PLEASE FORGET SELFISHNESS. Selfishness has taken its toll.
The present system of selfish society has to be amended/corrected to delete the word ‘SELFISHNESS’.
WE cannot bluff GOD/NATURE anymore.
YOU DECIDE OR NATURE DECIDES.

Answer 10

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.
