Cold is no longer an issue for farming with the russians.
Good stuff!!!
“Greenhouses that could benefit from this technology are springing up throughout the Arctic: The Japanese company JGC Evergreen produces 1,000 tons of cucumbers and tomatoes in Siberia”
“Modular Farms, an Ontario-based greenhouse company, has developed 400-square-foot containers that can produce thousands of hydroponically grown leafy greens”

Arctic and subarctic greenhouses in asia and north america will roughly double the amount arable farmland in the world and increase food capacity by 10 times.
There’s more.
Another kind of greenhouse is being adapted for desert regions.. They’re gaining increasing popularity because they use 95% less water than open air farming. These greenhouses use desalinated water—which is expensive —because the greenhouses sip water—they are economic. There’s a growing greenhouse industry in australia and the gulf states and a big desalination greenhouses in place in southern spain as well. Another feature of these green houses is that unlike the northern latitude greenhouses which hold in heat—desert greenhouses have ingenious ways of dispelling heat.
About a third of the worlds lands are deserts so these will double the amount of land that is available for agriculture and because green houses grow 10 times the amount of food on an acre of land as open air agriculture—these greenhouses will increase the amount of food available by 10 times.
Finally temperate zone greenhouses are exploding all over the place in the USA europe and asia. currently the second largest food exporter in the world is the netherlands. the usa is the largest exporter. how does the netherlands with a fraction of the land in the USA get to be the second largest exporter? greenhouses. the netherlands is now the greenhouse capital of the world. also they are re exporters of food from spain that is grown in greenhouses.
If greenhouses ever take over the farmland in the temperate regions of the world —they will expand production by 10 times.
That probably won’t be necessary because vertical farming will make most cities self supporting in a 100 years or less.
There are a couple more agricultural revolutions in the wings.
the point here is that the world can support populations 100-1000 times the size of the current population. That world won’t be as pleasant as this world but it can be done. and by that time population pressures and technology will allow people to move to the other parts of the solar system and maybe nearby stars.
I would love to know how many of these greenhouses use CO2 emitters?
I think that is one of the more telling scieintific facts against global warming.
green houses enable a vast increase in control over the crop. imho as soon as it becomes clear to the farming community that greenhouses eliminate climate and bug risk—and vastly reduce disease risk—there will be a vast migration to greenhouses in the farming community. as it is places like wisconsin are losing 2 farms a day.
