How can you change climate?

Answer 1

We are changing the climate by the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide.

We can change the climate back, if we act quickly and decisively. We need a global program of renewable energy and reforestation. We need to stop burning fossil fuels.

Change in personal lifestyles is just one of many solutions.

The easiest individual ways to help save the earth from climate change include:

• Print less- only print if it is crucial rather than wasting paper. Personally reducing paper use can be more helpful than one could think of.
• Work efficiently- the longer one uses electronic devices is the more one consumes electricity.
• Use your electronic devices wisely- turn of your computer, printer, TV and other electronic devices when you finish using them. The more electricity saved by turning off these devices rather than keeping them on is the more electricity save for a more needed reason.
• Recycle- Stop throwing used paper into your trash bin. Instead send them to recycling where they are put to better use than just sitting useless in a waste pile.
• Don't throw away used paper as you can use their other side. Using paper more than once can make a big change in your part, not only with the environment but you may also save money.
• AC/heating- the less you spend time at the office the less you consume energy on heating or AC. This relates closely with how efficiently you work.

Global Warming is the warming of our atmosphere, by the sun, and the retention of that heat by gases such as water vapor, carbon dioxide and other trace gases.

Without this warming effect, we would be a very cold and lifeless planet. The affect that this has on the planet is that life can exist.

In the mid 1800's we started to use more fuels and energy. Most of the development of this energy is done by fuels that emit carbon dioxide. Some believe, and there is some evidence to support the claim, that man is causing increases in this gas.

Pre 1800 levels of carbon dioxide are reported by science groups to have been about 300 ppm before 1800 and as high as 390 ppm during the summer months now.

This does not specifically agree with thousands of observations made in the 1800's which show carbon dioxide to be as high as 440 ppm. Even with this information in hand, no one can disagree that the current trend of carbon dioxide is upward.

The current warming trend we are currently involved with started about 10,000 years ago and all but 0.6 degrees of the 11 degrees of warming happened before 1800.
Well you see, Greenhouse gases come from burning things i.e cars, power stations, open fires ext. These release carbon Dioxide into the atmosphere. You see the sunlight will usely just bounce into earth and then back out again but with Greenhouse gases it gives the Greenhouse affect. That means that the light that bounces onto the earth instead of boucing out again it stays and keeps bouncing in the atmosphere because the Greenhouse gas is blocking it. And more sunlight means more heat and more heat means that the earths temperature rises meaning icecaps melting and rising sea levels.

Answer 3

The climate can only be changed by years and years of massive pollution, which the earth is in a state of.

A:There is substantial evidence that man can influence climate on a global and regional scale. So far the changes have been largely incidental due to the emissions of anthropogenic greenhouse gases which trap long wave radiation, thereby warming on a global level, and the emissions of sulphates which reflect solar radiation, thereby cooling on both a global and regional level. It is also likely that climate is changed through the emissions of black carbon particles, land use changes such as forestry and urban building, and the diversion and drainage of large volumes of water. Global climate change, both natural and anthropogenic can also potentially lead to significant changes on a regional level, although these are more difficult to prove or predict.

Whilst the most effective long term method of stabilising climate would be to reduce greenhouse gas emissions to natural levels, there is now substantial interest in controlling the climate to mitigate the warming caused from the release of anthropogenic (human produced) greenhouse gases. These geoengineering techniques fall into two main categories:

• carbon sequestration: These seek to capture and store greenhouse gases from the atmosphere. These include direct methods (e.g. carbon dioxide air capture) and indirect methods (e.g. ocean iron fertilisation).
• solar radiation management: These do not reduce greenhouse gas concentrations but reflect more of the suns radiation so they don't address problems such as ocean acidification, which are expected as a result of rising carbon dioxide levels. Examples of proposed solar radiation management techniques include the production of stratospheric sulphur aerosols, space mirrors, and cloud reflectivity enhancement.

(See geoengineering techniques in link for details)

Whilst, most of these geoengineering techniques are theoretically cheaper than reducing carbon over the short term, some might have unwarranted side effects, and therefore could be even more politically controversial. Some environmentalists also argue they are a serious distraction from the more important task of reducing carbon emissions, which would continue to rise to even more dangerous levels, and necessitate our continued dependence on geoengineering methods to stabilise climate.

Answer 4

the earth reflects its heat on the sun then it reflects even more heat back so it causes global warming
