Halting the vast release of methane is critical for climate, UN says

The reason methane would be particularly valuable in the short-term fight against climate change: While methane is an extremely potent greenhouse gas, it is also relatively short-lived, lasting just a decade or so in the atmosphere before breaking down....By contrast, carbon dioxide, the main greenhouse gas, lasts for hundreds of years in the atmosphere....it would take until the second half of the century to see the climate effects.

Qns:

1. Assess the view that attempts to control climate change can never be truly effective. (Cam. 2017)

2. Can we rely on science to solve our environmental problems?
