Do climate conferences actually achieve anything? A lot of people have strong opinions, but we wanted measurements, so we look at how the stock market moves during yearly international meetings called COPs – explanation below, or read the paper here:

Climate change DEFINITELY affects hurricane:
STRENGTH: Warmer water is hurricane food
RAINFALL: Warm air holds more water vapor
SURGE: Warmer water expands, warmer ice melts, sea levels rise
PREDICTION: hotter seas mean faster intensification

*** 1 metre of rain ***
Hurricane Melissa, a Category 5 storm, is forecast to bring catastrophic damage to parts of the Caribbean
The mountains of Jamaica could receive 1 metre of rain, resulting in life-threatening flash flooding and landslides
Destructive winds and storm surges are also likely

Roger Pielke Jr.’s Appallingly Bad Analysis of Billion Dollar Disasters – Economics from the Top Down
In a recent paper called Scientific integrity and U.S. “Billion Dollar Disasters”, Roger Pielke Jr. published a chart that's so bad I've devoted a whole essay to debunking it.
