Scientist found out that Yellowstone National Park in U.S.A will erupt 30-80 years from now. Yellowstone is considered as a super volcano. If Yellowstone erupted half of the planet will be covered with poisonous clouds of gas in an hour that will kill anything in its path.Tremendous Earthquakes and Tsunamis will hit Earth. Then temperatures will freeze on all parts of the earth and almost every species will die.
U.S.A have launched a project called Noah's Ark. It was launched in 2014 after the temperature in Yellowstone began increasing rapidly. That caused lake to dry.
Noah's project remains classified to the public. But it was revealed by a scientist who works at the project site.

But by the looks of it in our current situation  the condition of our planet is getting worse climate change is one of the effects of it.
