Coronavirus had bigger impact on CO2 emissions than Second World War, study reveals -independent
An international team of researchers has found that in the first six months of this year, 8.8 per cent less carbon dioxide was emitted than in the same period in 2019 — a total decrease of 1.5 billion tons.

Considering how many ships were blown up at sea with their fuel and or oil cargo burning on top of the water I would expect that WW2 was a carbon plus not a minus.

Lest we forget there were also major cities like Dresden and Tokyo fire storms that released all the stored carbon in the form of structures with wooden components, plus forest fires not being fought, plus military equipment, plus massive increased industrial output in North America as both Canada and the USA went to a war production schedule including building new industry and operating existing industrial plants 24/7/365 and so on and so forth. We basically went from a tiny air industry to sending thousand bomber flights over both Europe and Japan, massively expanded the merchant marine to ship goods and people all over the globe and to top it all off had to move workers from home to industry and back every shift.

Isn't it odd for September and October to have almost the exact same average?

Actually it is fairly typical, though the number are often further than 0.01 ppmv apart.

No evidence of any impact from the trumpeted alternatives whatsoever.

If they mattered there would have been at least a slowing down of CO2 increases.

RE: every place on earth gets the same amount of sunlight

The way I read it, Insolation, energy at the surface, is dependant on both angle of the sun and length of day. On average the equator gets about 3 times more insolation as the poles over the course of a year, measured in watts/meter2 according to this page.

The poles actually receive more total daily energy than the equator and lower latitudes during their summer equinox because of longer day length. But even then the lower angle means light must pass through more atmosphere before striking the surface, the atmosphere scatters the light making what reaches the ground weaker.

There is a table and graphs at the link

Correct, but in terms of making plants grow you need three basic factors. Temperature, Moisture and Sunlight. For the Arctic Ocean and coast for example the temperature at which phytoplankton can grow is just above freezing and as the ice thins over the spring and summer the green microscopic stuff starts growing like mad in the 24/7 sunlight. A bit further south around the Arctic Circle the period between thaw and freeze is relatively short, but the entire period is exposed to maximum sunlight duration which hits 24 hours on the Solstice and then gradually declines over the next 91 days to the Equinox when things start freezing up again. That is why cities like Helsinki, Finland and Fairbanks, Alaska can grow such massive vegetables like those cabbages where a single leaf covers about a square meter at harvest time.

Sure after September 20ish the daylight rapidly declines but by then you are entering frost and freeze season so the growing season is effectively over anyhow. For crops like Barley which the Viking grew with great success in Greenland before the freeze of the 14th century killed them off these long summer days bring on very rapid growth so where you can get a crop in 90 days in Ohio you can get it in 45 days in Fairbanks/Helsinki.

The Ag department calls this measure "growing degree days" or GDD. This is the measure of hours of daylight during which the temperature is above 50 F degrees and most common crops can grow. For Fairbanks Alaska this number is 1048 while in Anchorage it is 733 and in Juneau it is 634. For comparison because the frost free period is so much longer in Ohio we get about 3000-3500 because we thaw in early April and don't get a killing frost until late October. By the same token St. Augustine, Florida, oldest city in North America averages 7400 GDD annually because it almost never frosts, but day length is also never much more than 13 hours in summer or less than 11 in winter. Also note that while 50 F degrees is the "standard" crops like Barley actually start growing at about 42 F so the number for those locations given is the low end estimate for cool weather crops. Here is a nifty website, you can put in any zip code in the USA postal system and set it to annual and it will tell you the number of GDD for that location for 2020. For Fairbanks for 2020 and 50F as the temperature we get back 1180 GDD. For Beverly Hills, CA 2020 we get 5575 year to date and for my little bit oh land we get 3221 YTD. GDD Calculator
