Planetary Tilt Not A Spoiler For Habitation



"Present Earth is one of the most uninhabitable planets that we have
simulated," says Williams. "Approximately 8.7 percent of the Earth's
surface is colder than 14 degrees Fahrenheit on average, and this
percentage peaks at 13.2 percent in February owing to the large
landmasses at high latitude covered by snow."

The only planets colder than today's Earth are those planets simulated
with no tilt.

The Varanger simulation, with most land in the southern hemisphere, is
the most extreme with 15.6 percent of the surface below 14 degrees
Fahrenheit in July and 9.3 percent of the surface above 122 degrees
Fahrenheit in January. On average, nearly 28 percent of this planet's
land mass is uninhabitable by Earth standards.

How many people on Earth live in places where the maximum summer
temperature is 122 Fahrenheit (50 Celsius) and the minimum winter temp
is 14Fahrenheit (-10 Celsius) ?
