Temperatures have increased in the Big Wood River Basin over the last 30 years and are expected to continue through the 21st century.

Background

We use projections of future temperature to drive several important processes in the basin model. The first is evapotranspiration, the amount of moisture moving into the atmosphere from the combination of evaporation and plant transpiration from vegetation including forest, crops,and shrublands. This process is highly influenced by the Earth’s surface temperature.as well as for determining. The second process uses temperature to project changes in snowpack and snow accumulation rates for the basin. In particular, we looked at minimum and maximum air temperatures from each of the three climate scenarios, which we have provided as ihnteractive charts and maps below.

Key Findings

  • Air temperatures are predicted to increase in all future climate scenarios.
  • Compared to past climate (1980-2010) temperatures may increase between 4 degrees F in the low change scenario and up to 11 degrees F in the warm/dry scenario by 2070.
  • The average change across all three climate scenarios is approximately 7.5 degrees F warmer than the 1980-2010 average.

The Data

The following chart shows a summary of the basin average air temperature for the entire Big Wood Basin. You can "turn on" and "turn off" particular models by clicking on the legend entries near the top of the chart. Clicking the buttons at the bottom of the chart also filter the chart display by scenario. You can further filter the data displayed on the chart by entering a search string in the "Filter" box near the bottom of the chart.
