COP23: Writing the Paris accord rule book
Online — Having agreed to limit global warming, the COP must now figure out how to measure progress toward the goals set in Paris. Without double-checking this progress, the climate goals won’t be reached.
Two years after the world committed to climate action in Paris, negotiators are still trying to figure out the nuts and bolts of the global deal to limit global warming to less than 2 degrees Celsius.
A big part of that is developing a plan to monitor and verify the pledges made by nearly 200 countries to reduce greenhouse gas emissions.
During the two-week long COP23 talks in Bonn, negotiators are focusing, in part, on developing a system to make those measurements.
Writing that rule book is no easy task, says University of Edinburgh climate scientist Paul Palmer, part of an international team that assesses heat-trapping gases in the atmosphere.
“We need to measure carefully. We’ll be looking for small, gradual reductions of large numbers, so we need to make sure we get the numbers right,” Palmer told DW.
Explaining climate change science & rebutting global warming misinformation Scientific skepticism is healthy. Scientists should always challenge themselves to improve their understanding. Yet this isn’t what happens with climate change denial. Skeptics vigorously criticise any evidence that supports man-made global warming and yet embrace any argument, op-ed, blog or study that purports to refute global warming. This website gets skeptical about global warming skepticism. Do their arguments have any scientific basis? What does the peer reviewed scientific literature say?
