Hurricanes and Global Warming – Opinion by Chris Landsea
While I was looking into Chris Landsea’s recent activities, I came across a new essay that is a pleasant change of pace from the Climategate Emails. While it is definitely…
Earth's Climate System Is Ridiculously Complex – With Draft Link Tutorial
By WUWT regular “Just The Facts” I am often amused by claims that we understand Earth’s climate system, are able to accurately measure its behavior, eliminate all potential variables except…

Atlantic reversal
From Eurekalert: Earth’s climate change 20,000 years ago reversed the circulation of the Atlantic Ocean Global warming today could have similar effects on ocean currents and could accelerate climate change…
The Atlantic Ocean via the AMO drives the apparent “Global Warming”
By Joseph D’Aleo, CCM The North Atlantic undergoes a multidecadal oscillation appropriately called the Atlantic Multidecadal Oscillation or AMO. It is officially the mean sea surface temperature anomaly from the…
Arctic Temperatures and Ice – Why it is Natural Variability
