Atlantic reversal

Posted on November 4, 2010 by

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 circulation (termed meridional overturning circulation, MOC) is … Continue reading →

The Atlantic Ocean via the AMO drives the apparent “Global Warming”

Posted on November 2, 2010 by

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 equator to 70 degrees North. It went above the longer … Continue reading →

A MUST READ: European climate, Alpine glaciers and Arctic ice in relation to North Atlantic SST record

Posted on September 26, 2010 by

In my opinion, this essay is a must read because it clearly illustrates correlation between ocean cycles to; Arctic ice loss and gain, glacier advance and retreat, and land surface temperature rise and fall. As I said graphically in a … Continue reading →
