Nebraskans couldn’t escape the heat this summer — not even at night

Nebraskans this summer faced heat waves where daytime highs hit the mid-90s and overnight lows stayed in the 70s, undermining the natural cooldown residents like Pat Wilson-Johnson once relied on. Cooling centers in Omaha and Lincoln have stayed busy, handing out water, ice, and a place to sit through the heat.

Rising minimum temperatures pose risks beyond discomfort: cardiovascular and kidney stress, worse sleep, and higher energy bills for those running air conditioning through the night. A Climate Central report estimates Omaha and Lincoln residents lost about 30 hours of sleep a year to heat between 2020 and 2025.

The state's agriculture sector faces its own version of the problem, as corn and soybeans use more energy at night instead of storing it, potentially shrinking yields. Researchers say Nebraska's minimum temperatures could eventually resemble those of southern Missouri, changing conditions for crops and livestock alike.

Utilities, meanwhile, face growing nighttime electricity demand from air conditioners at the same time they're under pressure to power data centers, a combination pushing some to keep fossil fuel generation running longer.
