If it starts getting cold then crop yields will suffer, but the slightly warmer weather along with the CO2 enriched atmosphere of the last 30 years has provided bumper crops WORLDWIDE just as your article shows. Here is a list of bumper crops in this BEST ANSWER. http://ca.answers.yahoo.com/question/ind...
This fact represents another major prediction failure for the Warmist/Alarmist crowd. They have been predicting crop failures all along, the opposite happened.
Warmists are always scaremongering to try and push their global tax agenda forward but their predictions HAVE been consistent --- they have been consistently WRONG.
------------------------
We are getting bugs that damage our produce that have never lived this far north in recorded history, so yes- climate change is damaging agriculture RIGHT NOW, here.
Yes and no. Where agriculture is marginal, changes will be greatest. Wheat will be profitable to grow farther north in Canada. At the other end of its range, it will become unprofitable. Drier area will become more arid, requiring expensive irrigation. Wetter areas will become wetter yet, drowning out some crops.
That's the $64,000.00 question. First of all, if Climate Change is going to have greater local and regional effects for the foreseeable future local and regional losses due to weather extremes could easily be offset by improved yields elsewhere. Second, as technology has improved, yields have increased overall, and quite obviously, more arable land is being put into production globally.
Someone said that weather and climate are chaotic, and agriculture is a good illustration of the impact of chaos and why we cannot look at either in a limiting linear fashion. In this example, limited linear thinking says: More CO2=More Warmth=More Food Production. While this may be true short term there are other influences that render that sort of linear thinking limited and short-sighted. However, when one inserts technology into the mix, a more valid linear "formula" results: More Chaotic Weather=Development of New Technologies=More Effective Use of Arable Land=More Food Production.
It should be obvious to most observers with a modicum of understanding about agriculture that is what we are seeing and it doesn't have much to do with Climate Change-at least not directly, and not now. Those who predicted disaster decades ago were applying the wrong linear reasoning to reach erroneous conclusions. However, they likely didn't care-the main thing about what they predicted is they were trying to make money by publishing pop culture books and they were applying an entirely different type of linear thought. Many of them did pretty well at playing off the income producing opportunity demonstrated by Alvin Toffler's more insightful 'Future Shock' by following another linear formula: Find a Social Hot Button=Write Something Sensational About It=Attract a Lot of Attention=Make a Lot of Money. I doubt that they were too worried about what people like us have to say about them in 2013.
Like everybody else on the planet, I have a personal agenda that is fairly linear, and mine is primarily economic: Find Chaos=Buy Low=Fix Chaos=Sell High. Large scale chaos is pretty hard to fix, so I diversify to minimize large scale chaos-like weather and climate issues-by investing in small scale, local chaos that I can influence short term.
So here is my more direct answer to yet another interesting question you pose: Short term and due to technological advances, climate change will not damage GLOBAL agriculture. Economic chaos threatens agriculture far more than the weather-except locally. And on an individual level locally, failure to respond to chaos by adopting new technologies will cause the greatest damage of all to the persons or people who want to continue the status quo. Longer term (by my temporary definition here, if you will allow it,) of 100 or 500 years out, I don't know the answer to your question, but economics is likely to weed out the status quo contingent and improve our chances regardless. I hate to fall back on an old cliché, but buggy whip manufacturers resisted the development of transportation by internal combustion engines. I can imagine the conversations then got as emotional as they are now, but technology marches on and today's buggy whip manufacturer's-whomever they may be-will have to adapt and find new ways of making a living no matter how much they whoop and holler about how evil their opponents are. The old way of doing things will be forced out by the momentum of technology and the whoopers and hollerers will become the new buggy whip manufacturers cliché.
sure it will but not now in this present world but in future
Humans will adapt. We always have, though changes have been tough.
A history of Earth suggests the biggest threat to agriculture are large meteors, comets, a loss of magnetic poles, or insane humans that insist on screwing everything up for their own political gain.
It hasn't in my lifetime. Don't expect it to.
