Tampa, United States: Global warming is expected to make vegetables significantly scarcer around the world, unless new growing practices and resilient crop varieties are adopted, researchers warned on Monday.
By the end of this century, less water and hotter air will combine to cut average yields of vegetables -- which are crucial to a healthy diet -- by nearly one-third, said the report in the Proceedings of the National Academy of Sciences.
A 7.2 Fahrenheit (4 Celsius) increase in temperature, which scientists expect by 2100 if global warming continues on its current trajectory, reduces average yields by 31.5 percent, said the report.
"Our study shows that environmental changes such as increased temperature and water scarcity may pose a real threat to global agricultural production, with likely further impacts on food security and population health," said lead author Pauline Scheelbeek of the London School of Hygiene and Tropical Medicine.
Southern Europe, large parts of Africa and South Asia may be particularly affected.
The findings are based on a systematic review of 174 studies examining the impact of environmental exposures on yield and nutritional content of vegetables and legumes since 1975.
Some previous research has pointed to a likely increase in crop yields as carbon dioxide rises, but the current review found that any such boost would be cancelled out by higher greenhouse gases, reduced water availability for irrigation and rising temperatures.

Do these people even understand the concept of a GREEN HOUSE?
Hard to find or hard to grow?
ROTFL. Somebody wasted a lot of money setting up this “study”.
BS, CO2 is plant food.
More CO2, more plants.
Global warming. Women, minorites AND vegetarians hit hardest.
People will just have to eat crawfish instead.
That’s alright. If the fresh veggie aisle is bare I’ll just wonder over to the frozen veggie aisle.
What dumbasses.
Blah, blah, blah!
Yes, liberals - vegetables are grown in Canada, in Florida, in Mexico and in Alaska. And all those places have different average temperatures...
Warmer temps mean more h2o in the atmosphere, not less.
Yes, that is why there is no vegetation growing in the equatorial zone, no rain forests or nothing.
So, we’ll just eat more meat. ;-)
They better pray for global warming. Dinosaurs used to roam Antarctica, Montana, Canada etc.
Global cooling is the baddie.
A “greenhouse” is a closed system.
The earth is NOT “closed” and CO2 nor water vapor are capable of “closing” it.
LOL. They're not hard to find ... just inside the front door and to the right at Kroger.
The insane asylum residents will go to great extremes to get their agenda accepted, regardless of how insane it it.
Follow the money trail: That’s what it’s really all about and what they’re really after. Think of all the “carbon tax” revenue that leftists could pull in IF their views were fully accepted world-wide.
They need to be double-locked up in an high security insane asylum and the keys tossed into an erupting volcano.
Exactly. Global Warming will make the entire planet like Arrakis, from Dune.
THE SPICE MUST FLOW
Less veggies? Okay, start with squash, cucumbers, eggplants...
And suddenly we’re talking about a 7-degree F rise within the next 80 years. Earlier predictions were only ~3 degrees F in that period. And the “current trajectory” going by actual data is down, not up.
Never mind also that, if such a rise were to happen, there would be all kinds of new growing zones opening up. Also, hot weather = more evaporation, not less, and more humid air means more rainfall. There might be less groundwater available, but that has nothing to do with “climate change” in the short-term.
