A New Twist in the Climate Change Debate?

The one I keep the closest watch on:

Dramatic Rise in Arctic Methane Since End of July 2013

I'm sure it's nothing.

Lots of problems with the analysis of the draft report done by The Economist. See the link for where they got it wrong.

Interesting, thanks for the post.

I thought this part was particularly interesting.

In fact, we’ve learned from reviewers of the draft IPCC AR5 report that the scenario in question (1.3–1.7°C global surface warming by 2100) applies to IPCC emissions scenario RCP 3-PD. In this scenario, after peaking in 2020, our annual CO2 emissions decline at a rate of around 3.5% per year. Human greenhouse gas emissions actually become negative after about 2070, meaning we remove more CO2 from the atmosphere than we add. The scenario they’re considering involves extremely aggressive greenhouse gas emissions reductions.
