what preventions that the world do to prevent global warming?

Question

I hate to say this,
But I think the world is doing nothing for global warming.
Drats!

Answer 1

There isn't much we can do, as it is a natural thing... Just let it happen, it's life

Answer 2

Ya,it is a natural thing just that human caused it fast.

Earth has experienced warming and cooling many times in the past. The recent Antarctic EPICA ice core spans 800,000 years, including eight glacial cycles timed by orbital variations with interglacial warm periods comparable to present temperatures.

A rapid buildup of greenhouse gases caused warming in the early Jurassic period (about 180 million years ago), with average temperatures rising by 5 °C (9 °F). Research by the Open University indicates that the warming caused the rate of rock weathering to increase by 400%. As such weathering locks away carbon in calcite and dolomite, CO2 levels dropped back to normal over roughly the next 150,000 years.

Sudden releases of methane from clathrate compounds (the clathrate gun hypothesis) have been hypothesized as a cause for other warming events in the distant past, including the Permian-Triassic extinction event (about 251 million years ago) and the Paleocene-Eocene Thermal Maximum (about 55 million years ago).

Answer 3

Why could you decide directly to sidestep it? lots of the persons inhabiting this earth stay in heat climates and are thriving. If there became certainly scientific evidence that international Warming became a extreme undertaking, why are the scientists that are anti-warming ridiculed? isn't technological information all approximately consensus and information? the only information so some distance is that international Warming is only in accordance with politics, no longer technological information. occasion: Is Al Gore a flesh presser or a scientist?

Answer 4

Lock up the scientists fraudulently using it to cling onto their research funding + the politicians using it as a means to scam everyone out of more tax money!

Answer 5

The primary cause of manmade global warming is heat from the sun being trapped by greenhouse gases. The main greenhouse gases are carbon dioxide, methane and nitrous oxide, the largest contributor is CO2. It's this gas that many individuals and organisations are taking steps to reduce emissions of. Here are some practical steps you can take to combat global warming.


AT HOME AND WORK
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
● When replacing appliances buy energy efficient ones.

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

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

● Turn down water heating by a few degrees.

● Fit individual thermostats to radiators, don't heat empty rooms.

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

● Turn heating and air conditioning down by a couple of degrees.

● Sign up to a green energy supplier.

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

● Wash full loads of clothes

● Wash at lower temperatures.

● Dry clothes outdoors instead of in a tumble drier.

● Wash full loads in the dish-washer.

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

● Consider solar panels or a home wind turbine.

● Use rechargeable batteries

● Don’t leave (re)chargers on for longer than is needed.

● 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, avoid buying those that have been shipped long distances.

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

● Avoid 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 if possible.

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

● Shower instead of bath.

● If you bath, don’t fill it so much.

● Put a jumper on instead of the heating.

● Recycle and reuse where possible.


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.

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

● Walk or cycle to work or when taking the kids to schools, if you have to drive consider car sharing.

● Use public transport where possible

● Take 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, there's more information on the Eartheasy Website - http://eartheasy.com/live_fuel_efficient_driving.htm

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

● Keep tyres properly inflated.

● Remove bike and ski and roof racks when not in use.

● Carrying unnecessary weight wastes fuel, declutter your vehicle.

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

● Keep your vehicle regularly serviced.

● Turn the engine off when stopped or waiting.


CARBON OFFSETTING
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
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.
