Global temperatures have crossed the 1½°C or 2.7°F above preindustrial guardrail,

Whatever the results of the NZ election this is the reality.

NOBODY can do anything about this whatever the politicians pretend.

Global temperatures have crossed the 1.5 deg. C above preindustrial levels

Temperatures have crossed the 1½°C or 2.7°F above preindustrial guardrail, when looking at the NASA 1880-September 2017 (included) Land & Ocean data, adjusted for a preindustrial baseline and with a polynomial trendline added.

The image also shows that the 2°C or 3.6°F guardrail was almost crossed in 2016 for monthly peaks and it looks set to be crossed for annual temperature by 2028.

The situation could get worse much more rapidly than that, as the Arctic is warming more rapidly than the rest of the word, as the other image illustrates.
Accelerating Arctic warming looks set to cause massive loss of snow and ice cover, resulting in albedo changes and additional emissions, first speeding up Arctic warming even further, and soon thereafter also speeding up global warming, with further feedbacks kicking in even more strongly, as discussed at http://arctic-news.blogspot.com/p/extinction.html
