CO2 did not destroy Venus

Not long ago someone in the United States tweeted that this Climate Change thing is a hoax, because Venus has 97%CO2 and it is still there, so 0.04% CO2 is not going to destroy the Earth!  No it was not Trump, but he certainly reTweeted the post.  The danger has never been for the planet, but it has been a danger for the inhabitants.  

I recall that I had once thought of a plot for a SciFi novel that I wanted to write.     It was a story about three people that survived the doom that was Global Climate Change.  Each chapter would have a name, like so many books have been doing lately.  Each character gets to tell a story about what their survival has been like.  The first person a scientist that lived in the Arctic and his life venturing out onto the northern bogs as he carried out his research to remove Carbon from the air and the biosphere, his world is bleak, his habitat is fairly comfortable, but when he leaves his dwelling he must don a oxygen mask, as he would suffocate in the atmosphere that contains only half the oxygen that it would have had in the year 2000.  He sees the results of the devastation.  All mammals are dead, most of the animals are dead in fact.  There are birds flying around, but they prey on other birds to survive or plants.  He talks about other survivors that some other animals have also survived, crocodiles and fish, but these are smaller in number.  The plants are suffering too, but because there are no humans and fires do not have enough oxygen to burn, there is an abundance of litter.  All sorts of interesting sciencey stuff would be in these chapters.

Another character would be the son of a wealthy Televangelist living in an underwater habitat just off the Florida Keys.  The habitat was one of many shelters constructed by the wealthy and God's Blessed ones, a large cult that survived the Rapture and is waiting for God to free them to walk in Paradise.  It has been a long wait, bunt they are there waiting still.  Some of the cults have gone silent after the first year when they opened their habitats to walk into heaven and suffocated with the billions.  Now twenty years later this habitat is one of the few that have not been taken in and died from the sins of Hubris and Conceit.  

The third character lives in a computer.  She is young and was digitized not long before the end of earth.  She is one of millions who were sent on a long journey to a different planet.  Her spaceship is a small foot ball sized computer with a gigantic sail that first used the Sun's light to propel it and later used or will use e sail to slow that ship down.  The plan is to crash the ship into a new home and rewrite the ecosystem of the new home to be suitable for human life.  The rewrite would take a thousand years as self replications machines are built that alter the new planet.  These robot have the capability to creat life, building it from the cellular level and building bigger and bigger machines that can build bigger and bigger life.  This way they hope to be able to repopulate humanity amounts the stars.  The hope is that will be able to reintegrate the digitized humans into new bodies.  But at is the future.  Right now they are traveling through space, or have they landed? The computer representation of the world is a fractal fantasy similar to World of Warcraft, where the inhabitants are able to be entertained.  There is education as each individual is taught stuff about what is happening and the world they are going to.  About how the earth based astronomers selected these planets and sent the voyagers onwards 

==========

My point was that climate change, could destroy the ecosystem enough that the World is uninhabitable for humanity as we are now.  That there will be survivors, but the world will not look like it does now, the vast majority of humanity will die and a lot of life will die with it, but humanity might survive, or it might just end too.  But the planet will continue on spinning no matter what we do, with or without life on it.
