Global warming earth's orbit

  • About 55 million years ago, an intense heat wave hit the planet. Earths surface temperature surged by 9 degrees Fahrenheit (5 degrees Celsius).
  • (Huffington Post)
  • Changes in the Earth's orbit 55million years ago caused the planet to warm up by 5C, according to new research.
  • (Daily Mail)
  • A significant increase in carbon dioxide in the atmosphere, rather than changes to the Earths orbit, was likely the main cause of global warming that ended the last ice age, a new study has found.
  • (CBC)
  • The new view is supported by calculations estimating interactions of variables such as greenhouse gas levels, changes in the Earths tilt and orbit Similar dynamics are at play today.
  • (PhysOrg)
  • Small changes in Earths orbit around the sun affected the amount of sunlight That, in turn, would have amplified warming on a global scale.
  • (Eureka! Science News)
  • The peninsula is one of the fastest-warming places on Earth, jutting north of the rest of the frozen continent.
  • (msnbc.com)
  • The timing has been seized upon by sceptics as proof that man-made carbon gases either do not cause global warming or at least do not make it as bad as mainstream scientists say.
