In the vein of Network and "I'm mad as hell and not going to take it anymore", "Weathergirl" is audacious enough to explain, with the passion it merits, the seriousness of our climate situation. Enjoy the humor of and weep with the truth of Weathergirl Goes Rogue 2: Still Hot, Still Crazy.
As to the substance of the video and the linkage between food prices and instability, see this New England Complex Systems Institute discussion.
This summer's droughts in the American Midwest have pushed corn and wheat prices above their previous highs in 2011 and out of the reach of the world's poorest, threatening to trigger a new wave of global unrest -- perhaps even a second Arab Spring.
NECSI has shown that surges in unrest coincided with food price peaks in 2007-01 and 2010-11 [7]. During much of August and September, the price of wheat exceeded the high of $8.94 of February 2011, by which time the events of Arab Spring were underway.
Climate disruption is a very serious player in 2012's high food prices (think drought in the United States, to start with). And, with mounting climate chaos, we can only expect sort of climate change-driven disruption to the global agricultural system to occur more frequently and with more devastating impacts.
