What do you think about greenhouse gases, and how do you think we can reduce them?

The green house gases have been a lie . For instance they are saying that CO2 had increased 30% wrong,it should of but they didn't take into consideration the plants and photosynthesis. Plants take in CO2 to produce their food and give us back oxygen. The green house gas at 1.1% id too small to affect anything any way.

The most important gas, in terms of largest affects, is water vapour (H2O). Focussing on this gas and its effects, however, is considered a bit of a distraction. Human activity has little direct impact on atmospheric H2O levels. Unfortunately, though, water vapour does enhance the potential of other greenhouse gas emissions. So as other greenhouse gases (GHGs) accumulate in the atmosphere, water vapour adds to and increases their ability to change climate.

The main man-made GHGS (which we can do something about, hopefully) are carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). CO2 is the most important just because of how much of it gets released; it accounts for 84% of the total global warming effect from human sources.

Methane and nitrous oxide are most potent gases (they do more damage per tonne released), but they are only released in relatively tiny amounts compared to CO2.

Human sources of GHGs include any activity that burns fossil fuels (such as most energy generation and transport systems and manufacturing). Farming methods, such as rice cultivation and rising livestock, also produce GHGs.

Many people are worried the emissions of carbon dioxide and nitrous oxide from industrial processes and governments from many countries have signed agreements to try and cut down emissions to prevent this increase causing a rise in the temperature of the Earth. One such agreement was the Kyoto protocol, which came into force in 2005. Around 160 countries have now signed up to this agreement, which aims to cut down carbon dioxide emissions and to also control emissions of methane, nitrous oxide and three types of fluorinated gases produced by industry.

Green house gases. The important one is ( you guessed it) CARBON DIOXIDE!!!
Have you looked at a picture of Venus? That's how our earth's gonna look after 100 years, and maybe less time we keep using bad stuff.
