Natural Gas Is Not Going to Save the World

I found this article about the natural gas, and also it discusses why fossil fuels can't solve the problems created by fossil fuels. It's really a good article:
That truth is basic chemistry: when you burn natural gas, the amount of carbon dioxide (CO2) produced is, other things being equal, much less than when you burn an equivalent amount of coal or oil. It can be as much as 50% less compared with coal, and 20% to 30% less compared with diesel fuel, gasoline, or home heating oil. When it comes to a greenhouse gas (GHG) heading for the atmosphere, that's a substantial difference. It means that if you replace oil or coal with gas without otherwise increasing your energy usage, you can significantly reduce your short-term carbon footprint. 
Replacing coal gives you other benefits as well, such as reducing the sulfate pollution that causes acid rain, particulate emissions that cause lung disease, and mercury that causes brain damage. And if less coal is mined, then occupational death and disease can be reduced in coal miners and the destruction caused by damaging forms of mining, including the removal, in some parts of the country, of entire mountains can be reduced or halted. 
Also it discusses How Gas (CH4) Heats the Atmosphere Much More than CO2:
As a result, gas leaks are a cause for enormous concern, because any methane that reaches the atmosphere unburned contributes to global warming more than the same amount of CO2. How much more? This is a question that has caused considerable angst in the climate science community, because it depends on how you calculate it. Scientists have developed the concept of "Global Warming Potential" (GWP) to try to answer this question.
Most calculations of the impact of methane leakage use the 100-year time frame, which makes sense if you are worried about the cumulative impact of greenhouse gas emissions on the world as a whole, but not—many scientists have started to argue—if you are worried about currently unfolding impacts on the biosphere. After all, many species may go extinct well before we reach that 100-year mark. It also does not make sense if you are worried that we are quickly approaching irreversible tipping points in the climate system, including rapid ice loss from the Greenland and Antarctic ice sheets.
Also it discusses fracking, why gas is unlikely to be a bridge to renewable, exports and infrastructure: The road to more climate change, and so why are so many people so enthusiastic about gas?

  1. Its almost like a big public conspiracy to trick a large amount of the public into believing its better than oil when in reality its just as bad if not worse and also a way to keep renewable energy out of the picture because of this cheaper alternative
