If global warming is real, why aren't countries doing anything about it?

So, you're arguing that idea that Earth's climate is increasing is false because countries are failing to either prevent it or ensure their ways-of-life. Well, I think that argument is bogus. People willing disregard all warning signs, even with things far more certain than global warming. Everything from speeding, smoking, drugs, you name it. The average person willingly ignores all signs and wisdom. Now, before you say, "But these are countries, not the average person." Let me point out that countries do the same, and there is a long history of that too. The economic collapse in 2007 or the 9/11 attacks had major warning signs that were ignored, but those events happened --- despite the obvious consequences to the US government.
