This year's UN Climate Summit, COP 23, starts tomorrow in Bonn. Here's a preview from The Washington Post:
The 2015 Paris accord set a target of limiting global warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) — or 2 degrees at the most — by the end of the century.
But diplomats didn’t agree on the details of how their nations will reach that ambitious goal. The Bonn talks will flesh out the rule book that countries have to abide by.
This includes coming up with international standards for how to measure carbon emissions, to make sure that one nation’s efforts can be compare to another’s. A second debate centers around how countries take stock of what’s been achieved and set new, more ambitious goals for curbing carbon emissions after 2020.
The third big issue concerns money. Experts agree that shifting economies away from fossil fuels and preparing countries for some of the inevitable consequences of climate change will require vast financial resources — including some from the U.S. administration of President Donald Trump, which is doubtful about man-made climate change.
Fiji is hosting COP 23 but it's being held in Germany for a whole bunch of reasons.
