The surprising January heat record coincides with a new study by a climate science heavyweight, former top NASA scientist James Hansen, and others arguing that global warming is accelerating. It’s a claim that’s dividing the research community.

The National Weather Service has issued a winter weather advisory for Wednesday evening through Thursday morning.

From public libraries to community centers, the city of Chicago offers more than 190 public facilities where anyone can go to keep warm this winter.

If there were snow pack on the ground, Tuesday's temperatures could be closer to approaching record lows.

After Monday’s daytime temperatures hovered in the single digits, they are expected to dip to minus 10 to minus 3 degrees overnight, according to the National Weather Service. Flurries and isolated snow showers are also expected in the Chicago region.

It’s the first time in recorded history that the planet was above a hoped-for limit to warming for an entire year, according to measurements from four of the six teams. Scientists say if Earth stays above the threshold long-term, it will mean increased deaths, destruction, species loss and sea level rise from the extreme weather that accompanies warming.

In the Chicago area, the National Weather Service was predicting lake effect snow leading to hazardous road conditions throughout the day on Monday, including during the morning and evening commute.

Despite the frigid end to the month, November 2024 was still nearly 5 degrees warmer than normal. In fact, the entire year is on track to become the warmest since recordkeeping began in 1872.

Conditions for a potential winter storm never materialized, which should make for largely pleasant travel conditions this Thanksgiving.

Chicago notched 2.7 inches in the first snowfall of the season, according to the National Weather Service.

October 2024 was the ninth warmest in Chicago since record keeping began in 1872.

Warm temperatures combined with strong winds are also creating a fire hazard in northern Illinois, the National Weather Service warned.

The Great Lakes are likely to see more precipitation this winter, according to a newly released seasonal outlook from the Climate Prediction Center.

The South Side community experiences a large amount of flooding made greater than its counterparts on the North Side because of a lack of preventative infrastructure, which can cause significant damage to homes and businesses.

Sixty ComEd employees left Illinois Wednesday, heading to Florida to support workers there, a spokesperson said. And an additional 200 ComEd workers will be redeployed to Florida after finishing restoration in Georgia and South Carolina following Hurricane Helene.
