“Eco-blackmail” is not how you deal with climate issues

For where your treasure is, there your heart will be also.
Matthew 6:21

Looks like the other signatories to the Paris Accord believe ecological blackmail and piracy are the honorable path to follow and where their heart “lies” (double entendre intended). Thus, they seem to be more concerned about being paid to do what is right than doing what is right and in the perceived interest of the planet. Note that these nations had no obligation to reduce emissions, just to spend the money.
