What is the difference between air pollution and global warming?
Although both air pollution and global warming are different concepts yet they are interlinked in more than one ways. While air pollution can be defined as a local phenomenon of drop in air quality, global warming, as the name implies, is the unusual increase in concentration of green house gases in the atmosphere.Nevertheless, one factor that is responsible for both the phenomena is the extraction and burning of fossil fuels- in automobiles, industries, power plants etc. The burning of fossil fuel yields not only pollutants like particulate matter,NO2, SO2 etc. but also heat-trapping gases like CO2. While the pollutants are primarily responsible polluting the air, the green house gases are actually heating up the atmosphere.Moreover, there is another category of pollutants that are contributing both to air pollution and climate change. These are known as Short-Lived Climate-forcing Pollutants (SLCPs). This category includes methane, black carbon, ground-level ozone, and sulfate aerosols. However, the impact of these pollutants towards climate change is quite varied. While SLCPs like particulate sulphates are cooling the Earth by reflecting the incoming sunlight; others like Methane and Black carbon are heating the atmosphere by absorbing the same.It can be said that burning of fossil fuels is not contributing to air pollution at local levels but is also inflicting a long-term damage at a global scale by changing the atmospheric concentration of CO2 and other green house gases.
Why can't we simply invent a device that cools the air on a global scale, combatting the effects of global warming?
Many different global cooling schemes have been proposed. The two major mechanisms are Greenhouse gas removal and Solar radiation management. The former directly reduces the amount of CO2 in the atmosphere to decrease the heat trapped before it radiates into space. The latter reduces the solar energy absorbed by the planet, such as by producing artificial clouds to reflect light back into space.Many studies suggest that SRM would be a credible and cost-effective measure to delay global warming. (Although you can't ever stop, which is a bit scary.) If you wanted to, it could cool the planet even further than is required to offset the recent warming trend.For example, dispersing an aerosol of sulfates in the upper atmosphere has a powerful reflective effect to reduce the amount of sunlight absorbed by the planet. The effect was proven effective by the sulfur-laden eruption of Mt Pinatubo, which noticably cooled the entire planet -- so the only significant unknown is how to engineer the deployment system. Various proposals have been raised, such as adding sulfur to jet fuels, launching artillery shells into the air, and even building an enormous miles-tall pipe.Stratospheric sulfate aerosols (geoengineering)The cost of the "sulfur" plan to completely offset anthropogenic global warming has been estimated at $25-50 billion per year, which is easily within the means of a single large nation. But there are large error bars on that number -- no one's tried it yet.
What is the best ways to end pollution on a global scale?
Best way…. Here we goReduce pollution at sourcesReuseRecycle as much as you canGo for high efficiency machineGo for hybrid vehiclesUse renewable energy as much as possible as it is clean though it has low productivity and at low rate we have to go for itPlant tree that's the cheapest solution than Geo-Engineering technologyReduce use of carbon fuels like diesel, petrol and coal for vehicles, industry and so on.There is lot do to reduce pollution which currently going on international fora like UNFCCC, Kyoto protocol and soThanksBBR
What are the causes of air poloution? What are the effects of Air Polloution?
Almost all human activity, including -well farting! Jokes aside, it's also the computers and the Internet. They work on the power produced mainly by burning of fossil fuels and nuclear power plants-what of the nuclear waste-Chernobyl? Cars - they too work on processed fossil fuels As I said practically most human activity!
Air pollution..?
i hav got my chemistry project... its air pollution... can sumone plss tell me what all contents shud it hav (related to chemistry too) and then everybody in the class wud be referring internet for their information... plss can sum one tell me good books where i can find more about this and good links too tht my frndss cant reach to... thnxxx
What are the differences between thermal pollution and global warming?
If the world were a woman, thermal pollution would be like a phone in her pocket getting hot and global warming would be like her wearing so many clothes she can’t cool down.Global warming is just that - global. Thermal pollution is localised. For instance, the area around a factory may be warmer than the surrounding area because of heat escaping from the factory. It is not always a problem, but can be in cities where there are so many sources of thermal pollution there is no way for the heat to escape.On a global scale, thermal pollution is not large enough to make a difference. Global warming is caused not by heat sources on Earth but by heat not being able to escape into space. It is on a completely different scale.If global warming was caused by thermal pollution it would be the equivalent placing a 2 kilowatt heater every 16 metres in a grid that covers all the land on Earth. (Radiative forcing is 2.29 W/m^2: http://www.climatechange2013.org...)
Can you describe the following environmental problems?
Can you identify if the problems below are an example of resource depletion, pollution, extinction, or a combination of factors? Then identify the scale of the problem—local, regional, or global? You don't have to do the whole thing...thanks! 1. Climate Change – rising oceans, more severe storms 2. Energy – dependence on fossil fuels, shift to renewable power 3. Oceans – marine habitat loss, overfishing 4. Oil Spills 5. Oil Drilling 6. Biodiversity and Land Use – endangered species 7. Deforestation – loss of tropical rain forests and other habitats 8. Chemicals, Toxics, and Heavy Metals – leached into the soil, into the food we eat and water we drink 9. Air Pollution 10. Fresh Water – pure water is in short supply; overpopulation has caused many regions to be without clean drinking water 11. Waste Management – landfill waste 12. Ozone Layer Depletion 13. Overpopulation – world population recently reached 7 billion people 14. Radioactive Waste – from nuclear energy 15. Agriculture – pesticides (e.g., DDT), overpopulation 16. Untreated Sewage 17. Industrial Waste 18. Smog 19. Transportation 20. Pandemics – e.g., avian flu, swine flu
