New paper links warming since 1950 to ENSO and cloud cover variations

Watts Up With That?

John McLean writes of a new paper about the pattern in global average temperature anomalies since 1950 and how they are linked to changes in cloud cover and ENSO:

global-temperature-vs-cloud-coverKey points of the paper:

  • Indicates that the temperature pattern can be attributed to a
    sequence of events, namely a shift in the prevailing ENSO conditions,
    then a reduction in total cloud cover and then a shift on cloud
    (decrease in low level cloud that was largely offset by an increase
    in mid and upper level cloud)
  • Uses the Trenberth, Fasulo & Kiehl energy balance diagram to show
    that the loss in total cloud cover caused an increase in heat energy
    being absorbed at the Earth’s surface that was greater than the
    increase that IPCC 5AR claims was due to greenhouse gases
  • Indicates that greenhouse gases played little if any part in the
    warming, which not only refutes the IPCC’s belief…
