One year on from pledge, world clings to fossil fuels

Papua New Guinea, an impoverished Pacific nation vulnerable to climate shocks, says it is "sick of the rhetoric" and is boycotting this year's U.N.-led talks in Azerbaijan altogether.

Yep good idea that is the way to make your voice heard in a political arena. oh wait no it isn't boycotting only works when it is a large number of people hurting the pockets of corporations.

Papua New Guinea needs to be their and make their voices heard... a no vote is a vote for no change.

One year on from pledge, world clings to fossil fuels

It "clings" to fossil fuels because they are needed. One can not "pledge" miracles and expect them to materialize because of a "pledge". Sensible policy would be to encourage reduction via e.g. the tax system and to promote research into alternatives (e.g. Gen IV nuclear energy).

It "clings" to fossil fuels because they are needed. 

Renewables have been increasing in importance everywhere where they have been supported, "clinging" do not mean rely as little as possible but instead to unnecessarily make the energy grid dependent on them when other sources could easily replace a significant part of the energy production.

No miracles are being pledged, just a rational, perfectly possible transition from fossil fuels, a modest goal meant to replace the best changes that are realistically possible with much more modest ones just to increase the participation of the different countries. When countries reject even those much reduced goals because fossils are more profitable that is what is when criticism is valid.
