He explains that at low angles in the winter sky, the sun's light has to pass through more UV - filtering
atmosphere than in summer.

Rather
than keep the child
in the rarefied academic
atmosphere of New Haven or Princeton, West decided to slow down his academic career
in order to return to Sacramento with his child each
summer.
This season has been entirely different, more so
than it appeared it would after the opening day, where a lack of
summer activity contributed to a poisonous
atmosphere in a home defeat to Villa.
Due to the plateau's intense heating effects
in the
summer, the overlaying warm air can rise much higher into the
atmosphere than over adjacent lowlands.
To piece together geologic clues about what the early
atmosphere was like and how it evolved, Lowe, a field geologist, has spent virtually every
summer since 1977
in South Africa or Western Australia collecting rocks that are, literally, older
than the hills.
With the excellent
summer weather, world - class food and unrivalled holiday
atmosphere there's no better place to explore
in 2018
than Rovinj.
I think what Alastair is alluding to is the fact that, say by 2050 when the arctic ocean will conceivably be ice - free
in the
summer, the
atmosphere will have a much higher relative humidity
than it has currently because of the open air = water interface, so this will have a magnifying effect beyond just the feedback from increased CO2.
Moreover, the seasonal, regional, and atmospheric patterns of rising temperatures — greater warming
in winters
than summers, greater warming at high latitudes
than near the equator, and a cooling
in the stratosphere while the lower
atmosphere is warmer — jibe with what computer models predict should happen with greenhouse heating.
It is more efficient
in the winter to draw heat from the relatively warm ground
than from the
atmosphere where the air temperature is much colder, and
in summer transfer waste heat to the relatively cool ground
than to hotter air.
Both wetland drying and the increased frequency of warm dry
summers and associated thunderstorms have led to more large fires
in the last ten years than in any decade since record - keeping began in the 1940s.9 In Alaskan tundra, which was too cold and wet to support extensive fires for approximately the last 5,000 years, 105 a single large fire in 2007 released as much carbon to the atmosphere as had been absorbed by the entire circumpolar Arctic tundra during the previous quarter - century.106 Even if climate warming were curtailed by reducing heat - trapping gas (also known as greenhouse gas) emissions (as in the B1 scenario), the annual area burned in Alaska is projected to double by mid-century and to triple by the end of the century, 107 thus fostering increased emissions of heat - trapping gases, higher temperatures, and increased fire

So when
summer hits
in the southern hemisphere, one sees more CO2
in the
atmosphere than when it is
summer in the northern hemisphere.
During hot, humid
summer weather, many urban areas experience heat inversions — cold air
in the upper
atmosphere holds much warmer air close to the ground, sustaining higher -
than - average temperatures and trapping smog.
(A third of
summer sea ice
in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor
than cold, the
atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.)
After a few infrared measurements on
summer nights showed that the amount of heat being radiated from the
atmosphere was much less
than some climate models predicted, he began an intensive study resulting
in his own computer simulations based on available atmospheric data and well - known laws of infrared physics.
