Yes, global warming is impacting species and habitats across America and around the world. According to the U.S.'s National Fish, Wildlife, and Plants Climate Adaptation Strategy, warmer temperatures, rising sea levels, and other climate-related changes are stressing countless species of plants, animals, and fish.

Yes, there are, but the only new process on Earth that has been identified that can account for the significant tipping of Earth's carbon balance is human activity, including deforestation, biomass burning, cement production, and—especially—fossil-fuel emissions.

Considering some locations experience temperature swings of 30°F or more in a single day, warming of 1.5°F (0.85°C) might seem small, but Earth's annual temperatures are very stable when climate isn't changing.
