The Guardian regularly tells us that a change of 0.0001 CO2 concentration in the Earth’s atmosphere will make the planet uninhabitable.
Today the Guardian reports on another planet, which they say may be habitable.
Astronomers have discovered a potentially habitable planet of similar size to Earth in orbit around a nearby star….. “Our findings offer a very compelling case for a potentially habitable planet,” said Steven Vogt, an astronomer at the University of California …… Gliese 581g, has a mass of three to four times that of Earth and takes 37 days to orbit the star. Astronomers believe it is a rocky planet with enough gravity to retain an atmosphere……The average temperature on the planet is estimated to be between -31 to -12C, but the ground temperature would vary from blazing hot on the bright side and freezing on the dark side
I get it now. Earth is incredibly sensitive to minute changes in atmospheric CO2, but no worries – you could live on an alien world, 3X the size of earth, orbiting around a Red Giant, with an average temperature well below freezing, and where you would weigh 50% more than on earth.
Good clear headed thinking – as always.
