If Harris can be brought to pass some decent climate laws, which given her record is certainly possible, then the US might actually reach its way too low climate targets. Obviously state and municipality level changes also can improve it too. However that work has to be done by activists. With Trump there will be no pro climate policy on a federal level at all.
