How have humans changed the greenhouse effect?

Answer 1

Humans have altered the natural process of the greenhouse effect by burning fossil fuels for means of transport and electricity. The increased amount of fossil fuel that is being burnt has caused climate change. This has altered the greenhouse effect.

Answer 2

There are a number of human activities which interfere with the normal functioning of the atmosphere. Vehicular pollution- This leads to emission of greenhouse gases. Further, usage of old vehicles causes more pollution. Deforestation- This reduces the natural purifiers of the atmosphere, that is, the trees. As a result, the level of CO2 increases in the atmosphere. Poor agricultural methods- Mismanagement on the part of farmers can lead to emission of methane from agricultural products. Burning of anything- There are certain substances which must be handled otherwise rather than burning them else it causes emission of SO2, CO ,etc. Ever increasing number of industries- They are a huge source of CO2, SO2, NO2 and perhaps the improper treatment systems in these industries are a bigger cause of greenhouse effect as it does not purify the emissions to the fullest.

Answer 3

• Humans release over 40 billion tons of carbon dioxide into the atmosphere each year, by burning fossil fuel such as coal and oil. This CO2 does not fall back out of the sky the way water vapor does in the form of rain or snow. Instead, it lingers, absorbing heat reflected from earthurface, and gradually increasing the temperature of earth's atmosphere.

Answer 4

Many people are trying to cut back one using things that can hurt the ozone layer. People are carpooling, riding bikes instead of driving and many other things

Answer 5

by burning fossil fuels
