 In your lingo I would now be inclined to insert 13 question marks to
express my incredulity.

"And on January 5, the U.N. Food and Agricultural organization announced
that its food price index for December hit an all-time high.... But whereas
in years past, it's been weather that has caused a spike in commodities
prices, now it's trends on both sides of the food supply/demand equation
that are driving up prices. On the demand side, the culprits are population
growth, rising affluence, and the use of grain to fuel cars. On the supply
side: soil erosion, aquifer depletion, the loss of cropland to nonfarm uses,
the diversion of irrigation water to cities, the plateauing of crop yields
in agriculturally advanced countries, and—due to climate change
—crop-withering heat waves and melting mountain glaciers and ice sheets.
These climate-related trends seem destined to take a far greater toll in the
future."
