The Pope might think me stupid for any number of reasons and be right. Undoubtedly some poster will be glad to second that judgment as it comes to MMGW.
I am inclined to believe in MMGW, but for a different reason than many do. I remember, years ago, being on the French island of St. Bartelemy. Part of the island is lush and green, but not much of it. Most of it is a desert or semi-desert. In talking to the locals, they informed me that it was not always like that; that it had been much greener and rainier before, and that there were also a lot of trees on the upper reaches of the mountains that make up the island. When the trees were cut down, the rain became much more sparse.
I did a little research on it later and found that, indeed, in many oceanic islands the rainfall is largely determined by the trees. They delay and hold passing clouds and cause some loss of moisture in the process.
Most of the world’s habitable surface consists in “drylands” of varying degrees; that is, lands that are very dry for part of the year to all year long. Those lands are delicate, and mismanagement can easily cause desertification; desertification that does, indeed, cause air temperature changes and changes in rainfall and atmospheric water content.
Of the drylands, about 1/3 has become desertified due to human mismanagement, and it’s getting worse. Those circumstances can be fixed, but it takes a concerted effort to restore drylands. Nobody pays the slightest attention to that very important fact except for various scientists at the agricultural universities. All focus is on fossil fuels, the use of which, ironically, could be brought to bear to fix desertification if done properly.
Until all those who worry about MMGW think to address what is probably a more significant cause of MMGW (and CO2…no plants, no CO2 uptake) I am disinclined to take very seriously the calls for making fuel artificially expensive. It is incomprehensible to me why people would concentrate on remedies that cause human suffering when they could perhaps do better to concentrate on remedies that would actually improve the environment as well as the food supply.
