Ancient tree reveals cause of spike in Arctic temperature

Hmmmm……what does everyone think of this? ~ ctm Here is the abstract: Contrasting Greenland and Antarctic temperatures during the last glacial period (115,000 to 11,650 years ago) are thought to have been driven by imbalances in the rates of formation of North Atlantic and Antarctic Deep Water (the ‘bipolar seesaw’). Here we exploit a bidecadally…

A link between the solar magnetic field and weather patterns on Earth may explain our lower than normal severe weather in 2013

From the “science is settled” department comes this new paper that points out a correlation between the Interplanetary Magnetic Field (IMF) and polar jet streams, which drive weather events on Earth. This new paper shows that the effects extend even further towards the Equator than before, meaning it will affect weather experienced by a greater…

Steig on Antarctic warming: "Rossby wave trains"

From the University of Washington, comes this upcoming paper by corresponding author Dr. Eric Steig (and co-authors)that the mechanism for warming of the Antarctic Peninsula is mostly weather pattern driven. The mechanism cited? “Rossby Wave Train” aka the circumpolar vortex aka the southern polar jet steam transferring warmth from the tropical Pacific. I’ll have more…
