Leading scientist/PhD student: Maybe the oceans will boil more than a billion years from now

Watch out for the hot flushes (a few billion years away): Earth enters its mid-life crisis - News - The Independent
According to leading scientist Jack O’Malley-James, life on Earth will perish in more than a billion years when a warming sun boils oceans and forces out CO2, damning plants and subsequently animals..."Once you get to this tipping point [of evaporating oceans], you get a lot more water in the atmosphere and because water vapour is a greenhouse gas, that sets this runaway greenhouse effect,” the PhD student explained. “You end up with the Earth heating up to 100C or more plus what we experience today.”

I began my academic life as a physicist, then became a pseudo-biologist, before finally settling into the astronomy deparment at the University of St Andrews to put the two skill sets together to the task of astrobiology. I am now in the third year of an STFC funded PhD project investigating biosignatures of diverse microbial life on extrasolar planets.
