New paper finds climate models exaggerate projected warming

The Hockey Schtick:

A paper published today in Geophysical Research Letters finds climate models “suffer from temperature-dependent biases” which “leads to an overestimation of projections of regional temperatures.” According to the authors, “10-20% of projected warming is due to model deficiencies.” The paper adds to many other peer-reviewed papers demonstrating that climate models exaggerate global warming, regional warming, extreme weather, cyclones, extreme precipitation, droughts, and floods.

Temperature dependent climate projection deficiencies in CMIP5 models
Key Points

  • GCMs suffer from temperature-dependent biases
  • This leads to an overestimation of projections of regional temperatures
  • We estimate that 10-20% of projected warming is due to model deficiencies

    Leaked data from the IPCC even support the fact that there is little warming as a result of human generation of CO2. Now they spin the leaked data. http://wattsupwiththat.com/2012/12/24/ipcc-ar5-chapter-11-maintaining-the-spin/#more-76304

    @Nan G: Political garbage in and political garbage out. GW was always a political tool and not real science.

    @Greg: This is a post about global warming fraud?

  7. Randy one thing is right is that too much human on the same nation.
    I kept telling them to close the borders and close the immigration so the real citizens can get a better chance on jobs they are the first to get by right of their roots first,
    bye
