The years 2015 and 2016 saw record levels of excess carbon dioxide in the atmosphere, even though human carbon emissions have stabilized in recent years. Now, scientists think they know why.

Worth Doing Right: How Climate Change Could Throw a Wrench Into Road repairs

Repairing with the wrong materials for shifting climates could be a road to nowhere, like this spot in the Suffolk village of Covehithe. Picture by Timothyansell123.

The American Society of Civil Engineers has given America’s roads a D rating. But a recent study shows that trying to raise that grade without accounting for climate change could put the country’s roadways at risk.

The most extreme monsoon storms are growing more intense in central and southwestern Arizona, according to a study by the University of Arizona and the National Autonomous University of Mexico.

The findings conform to patterns expected under climate change conditions. Indeed, experts have already observed this effect.

Take Summer Headaches Seriously, Warns Neurologist

“The Headache” by George Cruikshank.

Between the heat, dehydration, air quality and July 4 fireworks, many Arizonans shrug off headaches as just another symptom of summer.

But Kerry Knievel, director of headache neurology at Barrow Neurological Institute, said we need to start taking headaches more seriously.

Parents tell their kids, “Shut the front door, I’m not paying to cool the entire neighborhood.”

But research shows that, during Phoenix summers, we do pay to heat the neighborhood — to the tune of 1 to 2 degrees Fahrenheit — thanks to waste heat vented by our air conditioners.
