Our planet faces wracking changes caused by climate change. Even if we lower greenhouse gas emissions to avoid crossing the 1.5 degree C danger line for global warming, the Earth is already warmer, the atmosphere is loaded with carbon dioxide that holds heat that used to escape into space, and we are heading for rises in sea levels that could inundate ports and coastal cities around the world.
