Definition — cusp: a point of transition between two different states
The transition from the Medieval Warm Period and the Little Ice Age was punctuated by extreme climate events, intense storms, floods, and droughts according to Lynn Ingram and Francis Malamud-Roam writing in The West Without Water. According to the authors, the transition from the Little Ice Age to the Modern Warm Period also experienced erratic weather extremes. Wolfgang Behringer, writing in the Cultural History of Climate, found similar transitions to more extreme weather. These extreme record-setting events are a signal that the overall climate is moving to a different state, in other words on the cusp of climate change.
Some recent record events:
Japan’s northern island of Hokkaido: Record cold temperatures, minus 24.4 C, the lowest seen since it began compiling such data in 1957.
Seattle: Coldest February in 30 years, the 4th coldest in 75 years, the 3 years that were colder were 1989, 1949 and 1956. “This month has been so snowy that it is now setting records for daily and monthly totals,” says the National Weather Service.
Minnesota: Minus 38 degrees recorded in Melrose, Minnesota, The nation’s coldest wind chill factor, minus 70, was reported in Ely, Minnesota on 30 January 2019.
Moscow: the Strongest snowstorm in 140 years, 13 Feb 2019
Siberia: Many record lows, details HERE.
Australia: Hottest December since recording started, with Adelaide hit nearly 116 degrees Fahrenheit the last week in January 2019, breaking an 80-year-old record high set in January 1939.
Sierra Nevada: June Mountain picked up 72 inches of snow in 24 hours, 96 in 72 hours. The official record for 24-hour snowfall record is 67 inches, on Jan. 5, 1982.
The proponents of anthropogenic global warming are attributing these extreme weather to human emission of greenhouse gases. However, after looking back through climate history, such as the Cultural History of Climate and The West without Water, I am inclined to attribute these record-breaking events to the transition point for the Next Grand Minimum.
Your thoughts, are we on the cusp, or is it just climate change weather?
