As the hot days in Texas get even hotter, it may just be too much for some birds and fish.
From the American goldfinch to the gray snapper, some species have been moving north for years, searching for cooler ground.
And their quest may someday lead them to migrate out of the state - forever - especially if climate change continues to make Texas warmer, as predicted.
Already, some areas in Texas, from grasslands to the coast, are under stress because of the heat, said Katharine Hayhoe, a research associate professor at Texas Tech University and one of the authors of the report.
The report says the heat will likely change natural systems and habitats such as prairie potholes or playa lakes, forcing some native plants and animals to other areas, potentially out of the state.
