Japan Meteorological Agency Shows First Three Months of 2016 Were About 1.5 C Above the IPCC Preindustrial Baseline

We should take a moment to appreciate how hot it’s actually been so far in 2016. To think about what it means to be in a world that’s already so damn hot. To think about how far behind the 8 ball we are on responses to human forced climate change. And to consider how urgent it is to swiftly stop burning coal, oil and gas. To stop adding more fuel to an already raging global fire.
Global policy makers, scientists, and many environmentalists have identified an annual average of 1.5 degrees Celsius above preindustrial marks as a level of heat we should try to avoid. [Link] The Paris Climate Summit made a verbal pledge to at least attempt to steer clear of such extreme high temperature ranges. But even the strongest emissions reduction commitments from the nations of the world now do not line up with that pledge. And it’s questionable that they ever could given the massive amount of greenhouse gas overburden that has already accumulated and is already rapidly heating the world’s airs, waters, ice, and carbon stores.
Current emission reduction pledges, though significant when taking into context the size and potential for growth of all of carbon-spewing industry, don’t even come close to the stated 1.5 C goal. Under our presently accepted understanding of climate sensitivity, and barring any response from the global carbon stores unforeseen by mainstream science, pledged reductions in fossil fuel use by the nations of the world under Paris would limit warming to around 3 C by the end of this Century. Rates of carbon emission reduction would necessarily have to significantly speed up beyond the pledged Paris NDC goals in order to hit below 3 C by 2100 — much less avoid 2 C.
As for 1.5 C above preindustrial averages — it already appears that this year, 2016, will see temperatures uncomfortably close to a level that mainstream scientists have identified as dangerous.
