Here’s what you’ll learn in this story:A new study analyzing different climate scenarios discovered that toxic fungi will likely spread into new areas in the future, possibly threatening millions. It’s estimated that scientists have only cataloged about 10 percent of all fungi on Earth, so unknown surprises would likely be in store as fungi spread beyond their historic regions. When writing about climate, lots of ink—or pixels, in a 21st-century context—is spent talking about the potential devastating impacts that climate change will have on plant and animal life. Hundreds of thousands of species of fungi have been described, but that’s likely only 10 percent of the total number of fungal species that exist on Earth. Though it has yet to be peer-reviewed, the paper details compelling evidence that our fungal future is a dismal one unless we seriously curtail carbon emissions in the coming years.
