@mightypythons,
There are many examples of incorrect farming because of the temporary changes of weather. The American "Dust Bowl", the early colonial farming of South Australia, are two that come to mind where farming was initiated on a temporary weather pattern only to have the weather change. Meterologists know that our weather has been unusually stable for about 10,000 years. As we are in an interglacial period, and the last wild weather patterns were just before the last glacial advances, we could be about to enter a glacial period.
However, the connection between climate and weather is rather vague. Climate drives weather, but the way it does so is not understood except in general terms. Remember it is only recently (50 yrs ??) we have learnt to predict short term weather with some accuracy. Farming is always dependant on the weather and I would rely on farmers to suggest improvements but from my observations we can do nothing but react after the weather has had its effect. I cant see that changing.
There is much that needs to be done to improve our relationship with nature, but the political will has been absent. Wars have been fought over natural resources and that will only get worse. For example, if Turkey were to dam the Tigris, what would Iraq do for water ?
Many had hoped Global Warming would give politicians the power to change things, but people objected to the guessing inherent to it. We need change to how we live in order to preserve the planet, but no one wants to pay the cost.
Economics will force change, but this will be a severe blow to the world economy, perhaps bringing about massive starvation and may occur too late for many eco-systems. The idea was that Global Warming would enable politicians to enact more gradual manageable change now, by being able to over ride people's objections to the cost.
One thing I am certain of, change will come whether we do it gradually or wait for one big lump to hit us.
