    Earth could be cooked into an uninhabitable hell in 200 years – and old uns’ burps and farts are partly to blame.

    Old folks, pumping out more methane and nitrous oxide in parps, belches and breath than youngsters, is adding to global warming.

    A study, led by Dr Nicholas Cowan from the UK Centre for Ecology and Hydrology, found a third of 328 breath samples contained methane. But only a quarter of folk under 30 produced it compared to 40% of those aged 30-plus.

    Those who did not exhale methane in their breath still probably released the gas “ion flatus” or burps and farts, the study said.

    Meanwhile, more eggheads have warned a dramatic rise in global surface temperatures could lead to our oceans evaporating.

    And humanity’s death spiral could be triggered by water itself with vapour trapping heat on Earth like a rescue blanket.

    Guillaume Chaverot, at the University of Geneva, Switzerland, said: “There is a critical threshold for this amount of water vapour beyond which the planet cannot cool down anymore.

    “From there everything gets carried away until the oceans end up getting fully evaporated and the temperature reaches several hundred degrees."

    His study – conducted by astronomers in Switzerland and at France’s CNRS laboratories in Paris and Bordeaux – used new climate models to show how a small increase of radiation from the Sun would result in an increase in global Earth temperature of just a few tens of degrees.

    That would be enough to trigger an irreversible runaway greenhouse spiral which would make Earth as inhospitable as Venus.
