Runaway global warming on our planet remains a distinct possibility in the decades and centuries ahead, scientists reported Monday in a new study, warning that a "hothouse Earth" threatens the very “habitability of the planet for human beings.”

Such a hothouse Earth climate would see global average temperatures some 6 to 8 degrees Fahrenheit higher than they are now, with sea levels 30 to 200 feet higher than today, the paper said.

In addition, even if the carbon emission reductions called for in the Paris Agreement are met – meaning a rise of no more than 3.6 degrees above preindustrial levels – that still may not be enough.
