One of the triumphs of climate modelling was the 2010 paper that pointed out that ice-free conditions in the Barents and Kara Seas (north of Finland) leads to colder winters in northern Europe

Nobody has done anything similar for the US food-bowl.
The UK Daily Telegraph can be relied on to put enough right-wing spin on any story to make even you happy. The most interesting part of any Daily Telegraph story is always what they've left out to make the story more palatable to people like you.
Sure, but it takes time - less if you practice genetic engineering, but that does worry a lot of people, some of them less dumb than Jamie.
It's an open question whether selective breeding can change our food plants enough to let them cope with the kind of climate change we've set in train, and whether natural biota doesn't already include a bunch of potential super-weeds which are already well-adapted to the the new conditions we are hell-bent on setting up.
The kind of super-weed which can rapidly colonise our carefully prepared crop-lands and out-compete our food plants at the seedling stage.
But - sadly for denialist pollyannas - their optimisation take the form of having less stomata so that they can take up the same amount of CO2 while losing less water.
That isn't a royal road to bumper crops - at best a partial defense against changing rainfall patterns.

Like most political hacks, you're an argumentative know-nothing of subhuman intelligence.
The chief climate science is political science.
That's what you like to think. It saves you from having to get to grips with the actual science involved, which turns out to be a little beyond you.
E.g. kindly point out to we fungi where the White House or NASA predicted the
hottest year ever would increase crop yields, or where they even announced
this unexpected result for corn and soybeans, in their effort to be earnest,
honest, forthright purveyors of the truth, and scientifically accurate.

Here's the agency you said wasn't part of the administration:
http://www.telegraph.co.uk/news/science/space/7875584/Barack-Obama-Nasa-must-try-to-make-Muslims-feel-good.html
"[NASA head] Charles Bolden, ... said in an interview with al-Jazeera that
Nasa was not only a space exploration agency but also an "Earth improvement > agency".
Mr Bolden said: "When I became the Nasa administrator, he [Mr Obama] charged me with three things.
"One, he wanted me to help reinspire children to want to get into science and
math; he wanted me to expand our international relationships; and third, and
perhaps foremost, he wanted me to find a way to reach out to the Muslim world
and engage much more with dominantly Muslim nations to help them feel good
about their historic contribution to science, math, and engineering."

He's some real scientific research on even more detrimental effects of high CO2. So you know what you can do with your CO2 inflated biomass of junk growth, you don't know the first thing about agricultural science.

More alarmism. Does any serious person think crops can't be selectively bred?
Sure, but it takes time - less if you practice genetic engineering, but that does worry a lot of people, some of them less dumb than Jamie.

It's silly. Ditto for the CO2 uptake saturation argument. If anything, that
non-coincidence demonstrates that plants cannily optimize themselves for the
prevailing conditions.
But - sadly for denialist pollyannas - their optimisation take the form of having less stomata so that they can take up the same amount of CO2 while losing less water.
That isn't a royal road to bumper crops - at best a partial defense against changing rainfall patterns.
