SciAm discusses 'symptoms' of climate change


Good read in Scientific American about climate change and health and disease.  There's a lot to think about here, so I'll just give one human and one (sob!) plant example.

Human:
" "Brain-eating amoeba" sound like something a zombie would infect you with. But the pathogen that causes the disease, Naegleria fowleri, is actually a microscopic organism that thrives in warm freshwater lakes and is almost always fatal. Although it's still rare, recent cases have occurred in Florida, Arkansas and Louisiana. 
"As freshwater lakes get hotter in the summer, that leads to more amoebae in the water and increased human risk," said Sonia Altizer, an associate professor of ecology at the University of Georgia. "
Plant:
"  For example, coffee-leaf rust, or Hemileia vastatrix, is a fungus that physically weakens coffee plants, prevents them from growing properly and ruins the crops for farmers. It has spread across the world, and the International Coffee Organization said it cost growers in Central America $500 million and 374,000 jobs in the 2012-13 crop year. 
One major reason the rust was so devastating in Central America was unusually heavy rainfall at high attitudes where coffee is grown. While single rain events can't be tied to climate change, heavier precipitation overall does have a climate link. "

Now, for many people, losing their morning cup of joe is like being infected with a brain-eating amoeba.  Even if it's not that bad, this is not good news for the economy OR the mental acuity.
