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…

Our route of flight from Reykjavik traversed the ice cap from about fifty miles north of Angmassalik to the airport at Ilulissat, on Disko Bay, about one-third…

Paper: ‘Summer temperatures were about 10°C warmer than today, even though the concentration of atmospheric CO2 was similar’

From AAAS: From Russia with Lovely Data Climate and the atmospheric concentration of CO2 are closely linked. Brigham-Grette et al. (p. 1421, published online 9 May) present data from Lake El’gygytgyn, in northeast Arctic Russia, that shows how climate varied between 3.6 and 2.2 million years ago, an important interval in the global cooling trend…
