In 2011, we published a paper that predicted continued warming could transform the Greater Yellowstone Ecosystem by mid-Century. I had no idea that just ten years later, I would bring my children to see this magical place, only to have it shrouded in wildfire smoke.

Each decade the National Oceanic and Atmospheric Administration (NOAA) releases a new set of U.S. Climate Normals, providing thirty-year temperature and precipitation averages that contain insight about both current weather and patterns in the near future. In early May, NOAA released the Climate Normals for 1991-2020, revealing the warmest recorded period to date.

The concept of resilience originated from biophysics to describe the ability of a system to rebound after disturbances. Resilience at the community level is defined by social scientists in disaster management as the capacity of a community to withstand and recover from disturbing events. Though individual agency plays an important role in constructing community resilience, a group of resilient individuals does not form a resilient community. Community resilience is greater than the summation of its individual members’ resilience.
How many trees are needed to take up the carbon dioxide I release every day?

Breathe in, and you consume oxygen. Breathe out, and you release carbon dioxide into the air. We know that burning fuels releases carbon dioxide, and our own “fuel,” or the food we eat, is no different. We capture the energy from the food we eat and then release the carbon from that food into the environment. On average, we eat about 2,000 calories a day and release about 2 pounds of carbon dioxide a day. Plants and trees use the energy in sunlight to take up carbon dioxide through their leaves and grow more biomass.
