Help to Find movie I seen

I saw a movie almost 10 years ago. It was made between 1990 to 2012.
At the beginning, there were some people on the earth going up to the sky (the gravity vanished) and news reporter was reporting the issue and they did not know why this happened. However that was because of some secret tests? At the end of the film, because of those tests, all the earth was filled with snow and everyone died or trapped in their home and the bad guy was in the plane and know that he will be alive until the plane have fuel, because after that, there is no place to land…

I think a poster below is looking for the same film, and I am struggling to find it for yall. Do you know if you saw it on dvd or tv? Could it be super low budget? Outside of snow/freezing, any other weather related stuff?
