TLDR
In this article, the authors examined past trends in the concentration of methane, the sources and sinks affecting its growth rate, and the factors that could affect its growth in the future, and examined the current understanding of the effects of methane on atmospheric chemistry and climate.Abstract:
The concentration of methane (CH4), the most abundant organic trace gas in the atmosphere, has increased dramatically over the last few centuries, more than doubling its concentration. Increasing concentrations of methane are of special concern because of their effects on climate and atmospheric chemistry. On a per molecule basis, additional methane is much more effective as a greenhouse gas than additional CO2. Methane is also important to both tropospheric and stratospheric chemistry. Here, we examine past trends in the concentration of methane, the sources and sinks affecting its growth rate, and the factors that could affect its growth rate in the future. This study also examines the current understanding of the effects of methane on atmospheric chemistry and climate.read more

Bounding the climate viability of natural gas as a bridge fuel to displace coal
TL;DR: In this article, the authors analyzed the time-evolution of radiative forcing from both natural gas and coal-based electricity generation by calculating the mean forcing over an interval of time from greenhouse gas emissions under a range of assumptions.
