'Connect the dots' global warming is a propaganda campaign being conducted by Bill McKibben per James Hansen's "climate science" - empirical measurements confirm Hansen's predicted tropical hotspot has not happened, it's a 'coldspot' instead
Climate alarmist James Hansen has long predicted the catastrophic tipping point of global temperatures from human CO2 emissions. His predictions include the seas will soon be boiling and a significant increase of extreme weather events, due to the excessive warming of the tropical atmosphere.
The excessive warming of the atmosphere over the Tropics is referred to as the AGW 'hotspot' and is the key signature of anthropogenic (by CO2 greenhouse gas) global warming.
Actual temperature measurements of the tropical atmosphere, as shown above, clearly indicate that the catastrophic 'hotspot' does not exist. Additionally, empirical evidence has the tropical atmosphere cooling over the last 15 years, at a -1.2 degree rate by year 2100, which is exact opposite predicted by IPCC climate models and the "experts," such as James Hansen.
