THE
Paris climate agreement, sealed last December, was a first in many respects: the first truly international climate change deal, with promises from both rich and poor nations to cut emissions; the first global signal that the age of fossil fuels must end; the first

warming.

warming.
At the same
time, a new paper published in Nature Geoscience examines the carbon budget for 1.5 C — in other words, how much more CO2 we can afford to release if we are to limit
warming to the goal of the
Paris Climate Agreement, taking into account recent emissions and temperatures.
This
time in
Paris can be either very
warm or very chilly, that's why I recommend taking ubiquitous layers for outerwear, wool blazer, at least one sweater and a classy raincoat with a hood.

timing is no great surprise: the world's political leaders will gather at the UN climate change conference in
Paris in December to decide on an international programme to limit global
warming.
Mind the gap: the $ 1.6 trillion energy transition risk is the first report to analyse the upstream financial implications for investors of the yawning gap between the
Paris Agreement, which pledges to keep climate change well below 2C above pre-industrial
times and aims for 1.5 C, and government policies, which are consistent with 2.7 C of
warming.
The report finds that under a
Paris - compliant cap for the EU - ETS, carbon prices would need to average $ 45 - $ 55 / tonne for a sustained period to drive coal and lignite power plants out of the market and keep emissions in line with the
Paris Agreement, which seeks to limit temperature rise well below 2 ˚C of
warming versus pre-industrial
times.
The
Paris Agreement, a treaty intended to slow global
warming, limits fossil emissions and forest clearing in order to keep the planet from
warming more than 2 degrees Celsius above pre-industrial
times, and possibly to keep the rise below 1.5 degrees Celsius.

Perhaps humanity would take that tack if we were trying to limit global
warming — say, we had already passed the
