Banana disease boosted by climate change
Black Sigatoka disease emerged from Asia in the late 20th Century and has recently completed its invasion of banana-growing areas in Latin America and the Caribbean.
The new study, by the University of Exeter, says changes to moisture and temperature conditions have increased the risk of Black Sigatoka by more than 44% in these areas since the 1960s.
International trade and increased banana production have also aided the spread of Black Sigatoka, which can reduce the fruit produced by infected plants by up to 80%.
"Black Sigatoka is caused by a fungus (Pseudocercospora fijiensis) whose lifecycle is strongly determined by weather and microclimate," said Dr. Daniel Bebber, of the University of Exeter.
"This research shows that climate change has made temperatures better for spore germination and growth, and made crop canopies wetter, raising the risk of Black Sigatoka infection in many banana-growing areas of Latin America.
"Despite the overall rise in the risk of Black Sigatoka in the areas we examined, drier conditions in some parts of Mexico and Central America have reduced infection risk."
[...] The Pseudocercospora fijiensis fungus spreads via aerial spores, infecting banana leaves and causing streaked lesions and cell death when fungal toxins are exposed to light.

By do anything you mean raise taxes and give money to themselves and their cronies? Because that is the only "solution" I ever hear from people who believe all that.
People actually doing something are preppers who are prepping for a grand minimum, while other people proposing ideas that could work to reduce CO2 emissions are nuclear power proponents. Neither have much overlap with the "government should save us from climate change crowd."
