Global Warming

What is global warming?

Global warming is the rise in the earth’s average temperature. Some scientist believe this is just a typical pattern with the earth’s temperature and some believe it is a proven set of facts. truth or theory this is greatly warming our earth. It is believed that human activity is the cause for this, fossil fuels, greenhouse gases are the main cause.

Greenhouse gases.

The most common greenhouse gases are water vapour, carbon dioxide, methane, nitrous oxide, ozone and chlorofluorocarbons (CFC) . some of these gases are natural like ozone but most of the others are greatly produced by human activity. 6% of all the gases is nitrous oxide, 14% is CFC, 18% is methane, 12% is ozone and a massive 50% of greenhouse gases is carbon dioxide which is cause by humans, we produce them in our everyday lives with cars, factories and power stations. Eventually even there is too much greenhouse gases a layer accumulate in the atmosphere. This is when the greenhouse effect takes place.

Greenhouse effect.

The sun naturally gives of radiation, some of this radiation goes directly into space and the rest goes into the earth’s atmosphere, this is our only natural source of heat without it the earth would be constantly in sub-zero temperatures. But when the sun’s radiation goes into the earth’s atmosphere it is absorbed then the earth itself releases its own thermal radiation which some of goes into space but some of it gets trapped due the the layer of greenhouse gases. When this radiation it trapped it means there is more heat in the atmosphere thus making the planet hotter.

In the long term…

it is obvious that if we continue to do nothing about this situation, in a couple of generation’s time the situation could be unthinkable. The planet is in a bad enough state as it is, the world’s beautiful coral reefs are dying, the sea level is rising, Antarctica has 70% of the world’s fresh water and 90% of the world’s ice. Due to global warming glaciers are breaking if Antarctica were to melt down scientists believe that the sea level would rise a whopping 5 metres that means that some small islands would be completely under water and several major cities of the world would also drown take the UK for example London, Edinburgh, Bristol, Preston and Carlisle they will all be under water if we continue to do nothing.

So what are the solutions?

There is no simple answer to this question, today the population is high and still rising. Little things we can do to cut down emissions use public transport or we you must use a car there are now hybrids which are less damaging to the atmosphere. Changing your light globes to energy friendly globes also saves power and money. There are a lot of humans in the world but if everyone make an effort and make this a habit it would do a great deal and reduce their carbon footprints.
