Environmental groups are suing the federal government for its decision to extend operations at the Four Corners Power Plant and the Navajo Mine in Fruitland.

The Farmington Daily-Times reports that the suit against the U.S. Department of the Interior and other federal agencies was filed in U.S. District Court in Arizona Wednesday.

The lawsuit alleges the agencies failed to thoroughly assess the potential impacts the coal-fired plant and surface mine could have on the environment and public health before approving the 25-year extension last July.

There’s been a mysterious drop in the number of endangered black footed ferrets in Arizona. They are the only ferret species native to North America, and researchers think disease, drought and other environmental factors could be affecting their populations. As Arizona Public Radio’s Aaron Granillo reports, the ferrets might not even be around today if it wasn’t for a dog named Shep.

The U.S. Department of the Interior will allocate nearly $95 million to a federal land conservation fund. As Arizona Public Radio’s Ryan Heinsius reports, Arizona will receive about $2 million through the program. 


Earth Notes: Bee Houses

When you hear the word "bee," you're likely to think of the hard-working insects that produce the honey we use. But in North American, a wild diversity of native bees - more than 4,000 kinds – swamps that of honeybees, which were imported from the Old World.


Travelers with a hankering to reconnect with nature and experience the Navajo way of life can do just that 12 miles south of Page.  A bear claw sign on Highway 89 points the way to the Shash Diné Eco-Retreat. “Shash” in the retreat’s name means “bear” in Navajo.

A new greenhouse gas study found the Earth’s land surface actually contributes to the warming global climate, counter to what scientists previously believed.

The study is the first to calculate the global balance of carbon dioxide, methane and nitrous oxide. It looked at only “biogenic” greenhouse gases, which come from plants, animals and microbes.

For allergy sufferers, dust and pollen are an irritating part of life in the Southwest. Yet recent research reveals that these tiny particles are crucial to the formation of life-giving rains, both here and around the world.

Most scientists today prefer the term “climate change” to “global warming,” since human-caused changes to the Earth’s atmosphere produce many changes beyond temperature. But especially in the southwestern states “warming” is an apt term too.

According to a new analysis of monitoring data by Climate Central, the U.S. is warming across the board—but to different extents in different places. And the effect varies by season, too.

Have cellphone, will travel: that’s the mantra in today’s device-driven world. Now, with a smartphone camera and a special app, a new project is providing virtual tours of archaeological sites in northern Arizona.
