Having sent young generations to kill and die in wars, the powers to be are now presiding over the greatest mass extinction of nature since 66 million years ago.
This paper presents a simple model to describe the impact on global warming of methane (natural gas) when used for energy production. The model is used to estimate the near-term effect of energy policies based on natural gas as a bridge fuel. The results make it clear that the commonly employed global warming potential of methane with a 100-year time horizon has the following problems:
1: it produces misleading results;
2: is inconsistent with meaningful tracking of greenhouse gas emissions; and
3: is incompatible with the precautionary principle.

The Arctic’s carbon bomb might be even more potent than we thought
Research released Monday suggests that methane releases could be considerably more prevalent as Arctic permafrost thaws.

One study in Utah estimated 6-12% of the methane produced from fracked wells there eventually leaked into the atmosphere (A. Karion et al., Geophys. Res. Lett. 40, 4393 (2013). Thats a HUGE amount of leakage.
Hopefully its not that bad everywhere, but there is a real problem there.
Cheers!
Its clear that increased use of NG is associated with increased leakage of methane to the atmosphere.

As I explained to you in another thread, people make typos all the time. Its no big deal unless some loon goes berserk and starts ranting on and on for days about it, and neither of us is at all likely to do that, are we?
