Isaac Held’s 2-box model: another failed ocean-equilibration excuse for dismissing solar warming

Guest post by Alec Rawls Dr. Isaac Held, who models fluid dynamics at NOAA, dismisses a solar explanation for late 20th century warming by invoking a 2-box model of ocean equilibration. In his model an upper upper ocean layer (100m or so deep) exhibits a rapid temperature response to any increase in radiative forcing (about…

Solar grand minima linked to cooling period in Europe

This is interesting. A quick cooling in Europe together with an increase in humidity and particularly in windiness was found to coincide with a long-term reduction in solar activity 2800 years ago during something called the “Homeric minimum”. The paper published in Nature Geoscience suggests that solar grand minima was the trigger for cooling of…
