An expert in urbanization and land use change is speaking in Aspen Tuesday. She has advice for land use planners in Aspen.


Karen Seto is a professor at Yale. She studies why cities are growing, how they grow and how their growth impacts the environment. People are moving to cities at a more rapid pace than ever before. And, urban areas generate three-quarters of global greenhouse gas emissions. She says urbanization increases demand for resources.

Climate Report: Temperatures Rising in Aspen

A new report on climate change in the Aspen area shows an increase in temperature and a rise in the number of frost-free days. The report was compiled as part of an effort to prepare the resort town for a changed climate.

The Climate Resiliency Plan looks at Aspen’s climate history. It shows Aspen saw a one-degree Fahrenheit increase from 1940 to 1979, and since 1980 a 1.5 degree increase. The report also shows a steady increase in the number of frost-free days. James Arnott with the Aspen Global Change Institute authored the report.

“This is one of the pointers that gets us to thinking about recreational seasons, such as a shortening of the winter and a lengthening of the summertime season.”

The plan pinpoints where Aspen may be vulnerable to climate change in the ski industry, for example. The report is a first step in an effort to engage community members in building a plan that finds ways to adapt to warming in the future.

In the future, the forests surrounding Aspen will look different. Already, mountain shrubs are replacing some Aspen stands and changing the complexion of the area.   This is likely due to due a warming climate.
