The most interesting scientific paper of the holiday season:

The world needs a significant investment now to kick-start climate change mitigation, according to a new study from European researchers.

In a paper published in the Proceedings of the National Academy of Sciences called "Near-linear cost increase to reduce climate-change risk", European researchers found a carbon dioxide “sweet spot”, where limiting the density of carbon in the atmosphere by a relatively small amount gave us a significantly higher probability of meeting climate change targets.

However, subsequent investments will have a more pronounced effect. And if we invest 2 per cent of global GDP in averting climate change, we have a 90 per cent chance of keeping global temperatures at 2 per cent above 19th century levels.
