Friends,
The potential impacts of climate change/global warming/climate chaos on
food supplies and security are among the scariest impacts.
The IPCC reported in 2001 that the Canadian Climate Centre's models
predicted that temps in the lower Great Plains could rise by well over 10
degrees F and that soil moisture could drop by 60 percent by the end of the
century. That's a desert, folks. It's happening as we suck dry the Oglala
and other aquifers, and as snow and ice pack is shrinking around the world.
At the same time, rising sea levels are likely to wipe out significant
percentages of our remaining coastal wetlands, coral reefs are in severe
decline, and rising acidity in the oceans is harming or is likely to harm
plankton that needs carbonaceous cells.
We're shredding the food web, in my opinion. For those who think that
global warming is not happening or that human activity is not at all
responsible, or that neither is proven, is it worth the risk?
Peace and happy Thanksgiving,

Over the last decade, average global sea level has increased ~ 3 mm/yr.
