Cool Time Lapse
According to new data from NOAA's National Climatic Data Center, there were 2706 new record high temperatures set in June versus 251 new record low temperatures.
That's a ratio of nearly 11:1, when the expected ratio over time should be about 1:1. On a yearly basis over the past decade the ratio has been about 2:1, with data showing that part of the issue is that nights aren't cooling as much as they used to.
From the 1950s to 1980s the ratio fluctuated between being slightly above and slightly below 1:1, but since the 80s it began increasing. Under a business-as-usual climate change scenario, we could hit 20:1 record highs to record lows by 2050 and even 50:1 by 2100. Should we successfully reduce emissions enough, by 2050 we may be able to constrain that ratio to 8:1.
Note from me; That would be new record high temperatures, hotter than todays record setting temperatures.
