Global Warming and Climate Change} what part of the planet would give the quickest response?

Climate change/ Global warming! and what area of the planet would have the quickest response to man's attempts to regulate some of the extreme weather events?                                                                       These questions can not be answered, without knowing how much effort mankind was willing to put forth. But in an ideal situation, if mankind could reduce the size of the Sahara Desert by 10% in a 20 year period this would be around 355,000 square miles, or the same as planting the size of 4 and 1/2 States of Nebraska (my home state and during the depression in the 1930's much of that state and others larger then Nebraska were terraced and had million's of acres of trees planted to help stop and end the dust bowl, yes this is like comparing apples and oranges but much of the food that American eat comes from the state of California which was a desert much like the Sahara desert, so we do have quite a bit of knowledge on the why's and how's, all we need is the water!) This amount of desert that would now be under cultivation would have a very large impact on the planet's weather but only if we use the whole area that would be used as a carpet of cultivation, not just individual trees spaced so far apart so as to get equipment between them. The most important part of the whole system is to produce enough ground cover to produce moist air in the atmosphere so we get cloud formations that will, in turn, reduce solar heat at ground level. Some plants would work much better at doing this than others, a perennial cover crop such as alfalfa would work better than an annual crop such as wheat, rice, beans, or corn, but this would mean that how we would use such crops for a food source. Alfalfa has a high protein content and could be used for fisheries and of course many types of animal feed. Many other types of plants could also be used bamboo, perennial grasses. This means that a whole new field of study of ground cover that also acts as a protein source with a deep root system to lock into place the easily blowing sand that would need to be used as soils over the rocky soil now in place of much of the Sahara desert. My name is Dan Kadavy until I started this Blog I did not use a computer, much too busy building homes and business since 1978, so you can call me computer illiterate! My phone is a flip phone, but that is all I need, in many ways, I am behind the times, but what this blog is about, concerns all life on this planet, not just mankind's! So please get everyone you know to read this blog, it contains most of what we need to do in the coming years,   https://lifecycleofaplanet.blogspot.com   There is a 12-page overview, along with around 130 short 2 minutes reads posts, that should point the world's people on how to proceed forward
