End Of The World As We Know It

All the madness from politicians over the past few decades could cause a snowball effect and people start voting for honest caring politicians, corporate capital is restrained, war is ended and humanity lives in peace until the sun dies in billions of years but that doesn't seem very likely because as i wrote here, that once a Civilisation develops a way to end all life on the Planet, it inevitably end up doing exactly that.
Scientists split the demise of the whole damn lot of us into two categories, human-caused (anthropogenic) risks in the near future and inevitable natural events billions of years from now so first the things we can do nothing about and are inevitable.
The Sun will slowly increase in luminosity, making Earth too hot for liquid water which will boil away and the Sun will expand into a red giant, likely consuming the Earth entirely which isn't great but that is up to 5 billion years away.
In the short-term and things we can do something about but stupidly don't is Climate Change and rapid global warming making the planet uninhabitable for humans and most species or a Nuclear War, pandemics  through natural or bio-engineered viruses or my personal favourite, a super-intelligent AI going rouge and deciding that all the humans problems are best dealt with by whacking us all.
There are also the threats from outer space which could involve an Asteroid Impact which could eliminate all life and making us the new Dinosaurs or a Gamma-Ray Burst from a Supernova striping the ozone layer and exposing all life on Earth to lethal radiation.
Based on models from the Global Challenges Foundation, researchers at the Future of Humanity Institute and the World Economic Forum the rankings of perceived risks for are pegged at 16% none of us will be around to welcome the next Century but they put the risks for how life will end are 100% for the Sun thing, 30% of pandemic either we made or a natural one, 10% for Ai running amok,Nuclear War 1% and Asteroid Impact 0.0001%.
Hopefully we will make it until the Sun decides to go Supernova but looking at some of the idiotic people making decisions, i wouldn't bet on it.
