The City of Lincoln understands the need to significantly reduce greenhouse gas (GHG) emissions to slow the pace of climate change and protect Lincoln residents' way of life. The changes in climate will result in several impacts to life in Lincoln. We will experience warmer, drier summers, wetter springs, more extreme rain events, more frequent drought, more frequent and intense floods, potential economic instability from impacts to the state's agricultural sector, and a range of climate-related health impacts, including heat-related illnesses, respiratory illnesses, and increased insect-borne diseases.
The ways in which Lincoln's future climate is expected to change by 2050 are significant.
- The mean average temperature in Lincoln is projected to increase from 52°F (1990 average) to 57°F (2050 average).
- Lincoln will see a 340% increase in the number of days where the air temperature and relative humidity will yield a heat index over 100°F. Of those, 26 days will be even hotter - they'll have a heat index over 105°F.
- Winter and spring precipitation totals will be 10-16% higher than current conditions, while summer precipitation will decrease by 4%.
- Heavy precipitation days in Nebraska are projected to increase 15% to 35% by 2050. Furthermore, multi-day extreme precipitation events will increase in severity.
Emissions
Most greenhouse gases—including carbon dioxide, methane and nitrous oxide—are associated with the production and burning of fossil fuels, which create energy for electricity generation, transportation, heating and manufacturing. Lincoln's Climate Action Plan sets a goal to reduce the community's emissions 80% by 2050, relative to 2011 levels.
The breakdown of greenhouse gas emissions from the Lincoln community as a whole in 2022 is illustrated in the chart below.
Lincoln's greenhouse gas emissions have declined 20% since 2011. The graph below shows the emissions trajectory.
