A recent study has created a simple mathematical rule that can account for the timing of the onset of interglacials following ice ages over the past three million years. The rule is based on predictable long-term astronomical variations in the Earth’s orbit and tilt called Milankovitch cycles.
A recent study presents evidence that regional warming over the Arctic Ocean can affect mid-latitude Northern Hemisphere continental weather. This study shows that there are two key Arctic regions where regional warming can induce distinguishable cold winters over northern continents. Warming over the Barents–Kara Sea region is likely to lead to East Asian cooling, whereas northern North America cooling is closely related to warming over the East Siberian–Chukchi Sea region.
In this new study an analysis of new global ocean and land temperature data with corrections to older shipboard measurements reveals that the temperature trend over the period 2000-2014 does not differ from the temperature trend over the period 1950-1999. It is concluded that the “hiatus” reported in IPCC AR5 is most likely an artifact of older measurement techniques.
