Hurricane Development Region Sea Surface Temperature Anomalies as We Start the 2014 Season

IMPORTANT OPENING NOTE Even if the sea surface temperature anomalies were to remain depressed throughout the 2014 hurricane season (highly unlikely), the actual sea surface temperatures (absolute) from June to November will rise to values capable of spawning hurricanes…a result of the normal seasonal change in surface temperatures. And while El Niño conditions in the…

Sanity Checking The National Climate Assessment Report Against Real Data Reveals Major Discrepancies

Let’s apply the scientific method, as outlined by Feynman, to the NCA report. We’ll first state each…

Climate Sensitivity and Transient Climate Response

Guest essay by Marcel Crok, Climate Dialogue Climate sensitivity is at the heart of the scientific debate on anthropogenic climate change. In the fifth assessment report of the IPCC (AR5) the different lines of evidence were combined to conclude that the Equilibrium Climate Sensitivity (ECS) is likely in the range from 1.5°C to 4.5°C. Unfortunately…
