By 2050 as a result of climate change, global “potential to produce food” could decline by 5 to 10 percent, after an average increase through 2020, said Andy Jarvis, an agriculture policy expert at the International Center for Tropical Agriculture, based in Cali, Colombia.

How many times have we heard that same story? Ehrlich said that we were going to starve 20 years ago. The 1970s ice age scare went like this :
There are ominous signs that the Earth’s weather patterns have begun to change dramatically and that these changes may portend a drastic decline in food production – with serious political implications for just about every nation on Earth. The drop in food output could begin quite soon, perhaps only 10 years from now. The regions destined to feel its impact are the great wheat-producing lands of Canada and the U.S.S.R. in the North, along with a number of marginally self-sufficient tropical areas – parts of India, Pakistan, Bangladesh, Indochina and Indonesia – where the growing season is dependent upon the rains brought by the monsoon.
Yeh, a basic (incorrect) Malthusian tenet. There is so much untapped potential for food sources, its amazing to me people buy into this propaganda. True, land is a quantified resource. The ability to use the resource can’t be quantified. Same is true with our energy resources. While there is an unspecified, vague finite limit to what we can extract, the ability to find, extract and use, going into the future, isn’t finite.
We continually grow better yields, and innovate better methods for energy locating, extraction and use.
Hmmm…I thought plants rather liked CO2.
They do. Though they tend to wilt in heat and drought.
I don’t know of too many fortune tellers that have been correct.
