Is climate change a Chinese hoax?

"About 90 percent of CFCs currently in the atmosphere were emitted by industrialized countries in the Northern Hemisphere, including the United States and Europe.

But scientists estimate it will take another 50 years for chlorine levels to return to their natural levels."

Although the above article is not about "climate" change but about ozone depletion, the cause of the trouble can be described in the same way. If we did not heed the warnings of the climate scientists, we could irreversibly damage our environment that supports our existence on this planet. Anyone with a modicum of common sense does not think that climate change is a Chinese hoax. Donald Trump and the Republican Party in the United(or Divided) State could be serious threats to human beings.
