Because there has been no warming of the planet for the last 17 years and because much of the data in support of that idea was fabricated or doctored, those foisting this "hoax" on the public had to change the terminology from "global warming" to "climate change," and now, every single "weather" occurrence outside of the norm is a result of "climate change." According to Al Gore, we already were supposed to have seen entire seashore areas under water, and because the U.S. is such a micro-fraction of Earth's surface, why would anyone think we can impact it?
