So the US is on track to meet the Paris Accord despite declaring that we are no longer agreeing to it, and some other countries that have agreed to it are not on track to meet their agreements?

The thing about agreements is they are meaningless without enforcement. I'd drop out too until the problem to be addressed is clearly defined, the solution also clearly defined with cost / benefit analysis done, participation from enough countries to meet the objectives, and legal remedies for failing to meet those agreements.
