how have human activites contributed to the phenomenon known as global warming?

Answer 1

There are several ways. First human beings have extracted prehistoric carbon in the form of fossil fuels. The when the fossil fuels burn the carbon is liberated in the form of carbon dioxide. Carbon dioxide has the ability to trap sunlight and re-emit it as infrared energy so its very good at trapping heat.
In addition, human beings have cut down large portions of forests in the tropics and temperate zones. Trees have the ability to use carbon dioxide during photosynthesis and store the carbon compounds as wood and leaves. By cutting down forests, humans have removed some of the ability of the earth to process the atmospheric carbon.
Humans have also increased enormously the numbers of grazing animals which produce methane as a by product of their digestive processes. Methane is also a greenhouse gas and while the total amounts of methane added to the atmosphere are small compared to the carbon dioxide, methane is about 300 times more efficient at trapping heat.

Answer 2

international warming, CO2 production and the Bio fuels craze are what's called “Bias technology” Taking statistical files from a narrow set to tutor their aspect. a good party of that's the upward push CO2 interior the earth’s surroundings. After H20 (Water vapor) CO2 is produced by volcanic and tectonic action in vast quantities. Mt St Helens for the duration of her very last eruption Emitted 22,000,000 Kg in line with day of CO2 for the duration of her very last eruption cycle. That went on for MONTHS. Now cases this by all the different volcanic eruptions, each and each and every of the CO2 produced by different geologic activities (warm springs oil and organic gas seeps) plate tectonics’ you commence on condition that mom earth is the most important CO2 criminal accessible. by how did you do not ignore that between the most important the reason why they say there is international warming is because the quantity of CO2 seen interior the Hawaii islands on suitable of Mona Loa? What they ignore to inform you is that Mona Loa is an lively volcanic mountain with 3 volcanic tiers! in addition they ignore to inform you that except someone funds a study they received’t do it. it extremely is why you don’t see CO2 sensors on a majority of those lively volcanos’s because the money isn't there to pay for the scientists to tutor how a lot CO2 is being produced. guy’s in common words effect on international warming is being brought about by the reckless destruction of the rain forests to grant bio-gas. Bio gas produces CO2 in its procedure and makes use of about 30 gallons of organic sparkling water to make 5 gallons. The waste emits CO2 and is a bio risk. in case you want to end mans effect on CO2 production, end scaling down the rain forests and bypass nuclear, boycott China because the use grimy coal to grant power and performance no emissions criteria in position. carry out slightly interpreting on the 1970’s and international cooling, you'll discover out that they are utilizing an identical technology for various motives.

Answer 3

Well.. let's see... there is a scientific study that says global warming may be caused by a massive cloud of hot air created by politicians yapping in Washington DC..

Answer 4

it is cause when the carbon dioxide which comes from the combustion of hydrocarbons(oil) destroy the ozone layer which allows the sun's rays to pass through more and melting the ice caps in the artic
