temperature in January ranges from 53 - 59 degrees F; summers are a little warmer with an average mean

Scientists sifting for trends in record
high and low
temperatures across the United States have found more evidence of long - term warming of the climate, with the biggest shift coming through a reduction in record low
nighttime temperatures.
This prediction failure has been due to the climate models assuming that minimum
temperatures (
nighttime temps) are driven by atmospheric CO2 levels, resulting in predicted minimum
temperatures that are too
high.
One study found that
nighttime low
temperatures are rising twice as fast as daytime
high temperatures, which is specifically a signature of greenhouse warming.
NOAA Coral Reef Watch (CRW) thermal stress products used in this study were based on
nighttime - only Advanced Very
High Resolution Radiometer (AVHRR) sea surface
temperature (SST) data from sensors aboard operational NOAA Polar - Orbiting Environmental Satellites (POES), produced in near - real - time at 0.5 - degree (50 - km) spatial resolution.
The point is that lack of your wondrous GHGs results in
higher daytime
temperatures, and lower
nighttime temperatures, in accordance with normal, rather than Warmist, physics.
From that I don't know what relative effects happen in the
nighttime set, but it seems to me that it would be most extreme then, because as anyone familiar with
high country will confirm, not only are
temperatures cooler in general, but there is a larger daily variation at
higher altitudes.
During extreme heat events,
nighttime temperatures in the region's big cities are generally several degrees higher28 than surrounding regions, leading to increased heat - related death among those less able to recover from the heat of the day.36 Since the hottest days in the Northeast are often associated with
high concentrations of ground - level ozone and other pollutants, 37 the combination of heat stress and poor air quality can pose a major health risk to vulnerable groups: young children, the elderly, and those with pre-existing health conditions including asthma.29 Vulnerability is further increased as key infrastructure, including electricity for potentially life - saving air conditioning, is more likely to fail precisely when it is most needed — when demand exceeds available supply.
I went to great length trying to explain to you that when you observe increasing or decreasing delta in daytime
high temperature and
nighttime low
temperature it is almost certainly due to concommitant trend in absolute humidity.
In recent decades the ITCZ has been migrating north moving it farther away from Easter Island and as that distance increases absolute humidity over Easter Island will necessarily decrease which necessarily means in increasing
temperature delta between daytime
high and
nighttime low.
Bottom line is if there were no greenhouse gases in the atmosphere like on the moon, daytime
high temperatures at the equator in the spring and fall would exceed the boiling point of water and of course
nighttime temperatures would plunge far below freezing.
