Climate change isolates Rocky Mountain butterflies
...butterflies, need sunlight to generate enough body heat in order to fly, and forests are generally too shady for them and inhibit their ability to move. However, expanding forests are pinching off the Parnassius from their neighbors in nearby meadows.

...nt by 2020. Carbon and other greenhouse gases trap heat in the Earth's atmosphere and are a major cause of global climate change. In California, transportation fuels account for about 40 percent of all greenhouse-gas emissions.
