As a lifelong gardener, I have observed changes in the climate. Plants that used to die off over the winter sometimes survive and grow again in the spring. St. Paul, Minnesota used to be in growing zone 4. The USDA just updated hardiness zones for the first time since 2012 and St. Paul is in Zone 5.
A warming climate is going to kill off some of the native plants including trees. There isn’t time for plants to evolve. They will die and with them insects, birds, fish, and mammals.
At the same time, various fungi and plant diseases that used to die out over the winter will survive as will invasive species of plants. None of this is good and sadly at this point, it will only get worse.
