President Joe Biden has brought the U.S. back into the Paris Climate Agreement, and there are efforts to reduce carbon emissions in an effort to slow climate change. But climate scientist Kimberly Nicholas says we all have a part to play in that.
Some planners are touting the idea of the "15-minute city" — an idea popularized in Paris in which residents are able to do most, if not all, of what they need and want to do within 15 minutes of their homes. Could that idea work in the Phoenix area? → More Stories From The Show
Extreme heat and prolonged drought have put an enormous strain on the Colorado River. As a result the life blood of the Southwest is maxed out.
The 40 million people that rely on its waters are now facing pending water shortages and cutbacks. KUNC’s Luke Runyon traveled along the 1,400 miles of the Colorado.

Phoenix is looking for input on its climate action plan. An online survey that can take as little as five minutes to complete asks residents and business owners to rank priorities and activities to limit climate change.
As drought strains much of the state, and tens of thousands of newcomers move to the busy Front Range each year, towns like Severance are thinking about growth – and water usage – in ways that they never have before.
Fewer greenhouse gasses were emitted globally over the last year, as people drove and flew less during pandemic-related lockdowns.
But new research suggests scientists may have underestimated just how big of a drop there was.
A push for more electric vehicles is bumping up against a western Arizona tribe’s sacred sites and land.
A mining company is looking to extract lithium on land owned by the Bureau of Land Management, but that land surrounds Hualapai land on three sides.
A recent project led by ASU’s Center for Science and the Imagination melds data, essays and fiction in presenting how cities and communities may be changed by a stronger move to renewables — including solar energy. And the project is captured in a book called "Cities of Light: A Collection of Solar Futures."
In 2010, the city of Phoenix adopted the Tree and Shade Master Plan, which called for the city to increase environmentally-friendly efforts. One of those efforts was to increase arboreal coverage of the city. On June 16, the city passed an ordinance that would codify some of its provisions into municipal law.
Trees can provide relief from the heat during the summer months, but ASU researchers say that other forms of shade can also be effective. The findings can have benefits for city planners looking to offset the heat island effect.

Arizona has a groundwater problem. Outlined in a new report, called “The Myth of Safe Yield,” the authors note that if we could see our groundwater aquifers underground, many would look like the images we’ve seen of Lake Mead, with its bathtub ring indicating falling water levels. → More Arizona Science News
