The likelihood of the complete loss of Arctic summer sea ice by 2030, faster melting of the vast Greenland ice sheets, and the rapid and quickening thaw of permafrost regions indicate that the window for arresting climate change before tipping points are reached is rapidly closing.

likelihood of steep market
losses over the
complete cycle, and also for poor S&P 500 total returns on a 10 - 12 year horizon, but valuations often have little effect on near - term market behavior.
