Cannibals and Climate Change

Ok … there is the term “Jumping the Shark”

I think this headline is a Jumping The Shark moment.

120,000 years ago the temperature was COOLING at about 1C per 1,000 years after it spiked 130,000 years ago.

Maybe they meant 135,000 years ago when the temperatures rose 10C (without SUV’s) in 5,000 years …. which is still only 1C per 500 years. I doubt someone living 25  years would notice .02C in their lifetime.

UHI in the UK raises Tmin by 1.7C

UHI causes Tmin go  up by 1.7C in UK

The observed increase in T min can be attributed to an increased intensity of the UHI during the hours after sunset and into the night. Many studies have previously shown that UHII is maximised during the night (Arifwidodo and Tanaka, 2015; Montávez et al., 2000; Ripley et al., 1996). The intensity is maximised during these hours, as heat absorbed by urban structures will be re‐radiated back into the atmosphere at a slower rate, due to smaller sky views, than natural structures. Further, the increase in impervious surface in an urban area causes a reduction of the latent heat flux and a rise in the sensible heat flux (Zhou et al.,2014). This leads to a difference between the rates at which the urban and natural area will cool during the night, with urban areas sustaining a higher temperature into the night. With minimum temperatures often occurring at night, the slowed rate of cooling in urban areas results in an increase of the observed minimum temperature.
