There is a lot of debate over this, but if you look at the facts and use common sense you will realize they know something they don't want most people to know.
One fact is that countries around the world have built underground bunkers, cities, etc.
Another fact is that the Vatican purchased a very expensive telescope they use in the US, it is specialized so it could see a brown dwarf star in our solar system.
Apparently during George H.W. Bush's presidency they discovered that Wormwood would hit the Earth and told all the nations.
Another fact is they have the whole world believing we have 7 years until 2030 despite all previous prognostications concerning "climate change" have been a farce. Therefore the leaders of every nation on this earth are fools and morons, or else they know something that they don't want to tell you.
I did read that nasa says there is evidence that there could be a plannet x but say they haven't spotted it yet.
But I did see something about an image capture on the edged of the solar system that nasa couldn't fully say it was another plannet, where as other sources said it was.
Interesting to say the least,
There's definitely something there not telling us with climate change, that's for sure.
What ever that something is I don't know, but I feel it has something to do with using up the earths natural resources, that is more of an issue.
One of the personal beliefs I have is as you know oil also acts as a coolant in a car engine, that gets extremely hot.
Well the more oil you take out of the ground the more hot spots get hotter
