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
