"Mom. The permafrost is melting. Millions of acres of it."Willa tried to see a connection. "And I'm just worried about my house. That's your point?"Tig shook her head. "It's so, so scary. It's going to be fire and rain, Mom. Storms we can't deal with, so many people homeless. Not just homeless but placeless. Cities go underwater and then what? You can't shelter in place anymore when there isn't a place."Willa tucked her hands between her knees and declined to believe these things. "The Middle East and North Africa are almost out of water. Asia's underwater. Syria is dystopian, Somalia, Bangladesh, dystopian. Everybody's getting weather that never happened before. Melting permafrost means we've got like, a minute to turn this mess around, or else it's going to stop us."
