Illinois is rebranding Asian carp as “copi” in a bid to get people to eat the invasive fish into submission. Fishermen are catching thousands of pounds a day and barely making a dent in the number of carp in waterways like the Illinois River, where it's estimated 20 million to 50 million could be harvested annually.

In 2021, worldwide emissions from making cement for buildings, roads and other infrastructure hit nearly 2.9 billion tons of carbon dioxide, which is more than 7% of the global carbon emissions. Twenty years ago, in 2002, cement emissions were some 1.4 billion tons of carbon dioxide.

As a pair of wildfires skirt Flagstaff, the flames are crossing land dense with reminders of human existence through centuries — multilevel stone homes, rock carvings and pieces of clay and ceramic pots that have been well-preserved in the arid climate since long before fire suppression became a tactic.

Chicago isn’t likely to break the 35-year-old record high of 99 degrees set for June 14 back in 1987, even though the heat index is expected to top 105 degrees. Which begs the question: What is the heat index?

Several sites in northeastern Illinois — including Waterfall Glen, Des Plaines Riverway, Hidden Lake and Wood Ridge forest preserves — will be sprayed with fake pheromones to confuse spongy moth males and disrupt mating.
