Earth's Energy Imbalance
  The earth is absorbing more energy from the sun than it's
  giving up due to increasing greenhouse gas concentrations.
  The excess energy that the planet is absorbing is enormous.
  The total energy imbalance now is 0.58  0.15 W/m^2.

  From the Laws of Thermodynamics earth must warm until it
  reaches a new equilibrium (Ein = Eout) at higher temperature.
  Given current concentrations of greenhouse gasses, the earth
  will continue to warm for centuries.

The Carbon Dioxide Greenhouse Effect

  In the early 1960s, C.D. Keeling measured the level of
  carbon dioxide in the atmosphere: it was rising fast.
  Researchers began to take an interest, struggling to
  understand how the level of carbon dioxide had changed in
  the past, and how the level was influenced by chemical and
  biological forces. They found that the gas plays a crucial
  role in climate change, so that the rising level could
  gravely affect our future.


  One of the first and most-recognized indicators of society's
  impact on climate is the "Keeling Curve," a measurement of
  CO2 concentrations in the atmosphere began by Charles David
  Keeling, a geochemist at Scripps Institution of
  Oceanography, UC San Diego. Keeling set up ultraprecise
  measurement devices atop Hawaii's Mauna Loa and in March
  1958 made a reading of 311 parts of carbon dioxide per
  million of air. That was already elevated from an average
  concentration of 280 ppm before the onset of the Industrial
