National parks bear the brunt of climate change

  • Temperatures in national parks are increasing at twice the rate of the US as a whole; most exposed national parks could soar by as much as 9 degrees Celsius or 16 degrees Fahrenheit by 2100.
  • Without action to limit greenhouse gas emissions, many small mammals and plants may be brought to the brink of extinction by the end of the century, the study shows.

Human-caused climate change has exposed US national parks to conditions hotter and drier than the rest of the nation, says a new study quantifying for the first time the magnitude of climate change on all 417 parks in the system. Without action to limit greenhouse gas emissions, many small mammals and plants may be brought to the brink of extinction by the end of the century, the study shows.

….At the current rate of emissions, the team projects that temperatures in the most exposed national parks could soar by as much as 9 degrees Celsius or 16 degrees Fahrenheit by 2100. This rate of change is faster than many small mammals and plants can migrate or “disperse” to more hospitable climates…..
