How can pollutioncause global warming??

Question

Ummm.... I need somthing like details.......and information.pls

Answer 1

Pollution causes global warming in different ways.

Most of our energy needs are catered for by the burning of fossil fuels - coal, oil and gas. These are hydrocarbons, meaning they consist of hydrogen and carbon atoms. When they're burned they react with the oxygen in the air to produce H20 (water vapour), CO2 (carbon dioxide) and other gases.

Many industrial process produce different types of waste gases, particularly chemical, power generation, mining and manufacturing plants.

These gases enter our atmosphere and retain heat from the sun. Some gases retain more heat than others, carbon dioxide doesn't retain that much heat compared to some gases but because it accounts for nearly all manmade atmospheric pollution it is the primary cause for concern.

Pollution comes in many forms, there's the obvious ones from power generation, industry and transport but there are other less obvious ones such as agriculture, effluent and landfill.

Cattle produce an amazing amount of gas through burping and farting, this alone accounts for 20% of methane released into the atmosphere - a far more damaging gas then CO2. Other animals contribute as well but to a lesser extent.

Agriculture uses a lot of nitrogen rich products such as fertilisers and this creates nitrous oxide, a very damaging gas. It's also a byproduct of animal and human waste.

Decomposition of animal and vegetable matter releases large amounts of methane, carbon dioxide and other gases. You may have seen gas flares on landfill sites, this is burning off pockets of methane that have formed as the garbage has decayed. It happens a lot in nature, all the plants and animals that die end up decaying or being eaten and release all sorts of gases and minerals as they decompose.

This answer only scratches the surface, there must be at least 1000 other ways in which pollution contributes to global warming. I hope it gives you something to go on.

Answer 2

You need a better question like, how do we know the globe is getting warmer?
The surface area of the USA is 8,000,000 square kilometres. There are 4,000 weather stations in the US located on the surface of the earth. Therefore, one weather station for every 2,000 sq kilometres of surface area. The atmostphere is 100 kilometres thick. So, one (1) temperature reading is taken for 200,000 cubic kilometres of atmosphere.
Is the temperature constant throughout that volume? Obviously not.
Is this temperature reading a measure of overall change of the earth's atmostphere? Impossible.

Answer 3

the best and most comprehensive source of information for the general public can be found in a movie called "An Inconvenient Truth" by Al Gore. He's been berated recently because of his lifestyle, but you need to look beyond the concept of "shooting the messenger"! What he is saying is extremely valid, scientifically researched, well put and very hard to ignore. The Oscar which he won wasn't for nothing, after all!

Love and Light,
