On a warm afternoon in Boulder, a small group of residents and scientists walked alongside South Boulder Creek.

"Today, we are here to talk about our regional air quality," said Jennelle Freeston, the volunteer coordinator for Boulder's Open Space and Mountain Parks.

What if you could look at the plants in your garden in order to learn if the air around you is clean or dirty?

At the National Center for Atmospheric Research in Boulder, scientists have planted a garden that does just that.

Scientists have linked earthquakes in Oklahoma with wastewater injection wells associated with the oil and gas industry, in a new paper published in the journal Science.

Four injection wells with a "high rate" of injection, meaning they accepted a large quantity of barrels of wastewater per month, likely caused 20 percent of earthquakes in that area from 2008-2013, the researchers said.

The Colorado Oil and Gas Conservation Commission has ordered a 20-day halt to wastewater injection in a Weld County well following a 2.6 magnitude earthquake in the Greeley area June 23.

As Colorado Gov. John Hickenlooper weighs whether to call a special legislative session to deal with oil and gas issues, the issue of property rights is on his mind.

The governor has equated some of the recently passed bans and moratoriums on hydraulic fracturing to "…snatching the property of a citizen. Just taking it without due compensation."

While in some cases the courts could interpret fracking bans as taking away private property, getting to the point where a ban is ruled a taking of private property would be time consuming and costly, experts say.

After a rare magnitude 3.2 earthquake northeast of Greeley, scientists hope to learn more about any possible future quakes in the area. They’ve quickly mobilized to set up a network of five instruments that monitor for earthquakes, all around the epicenter of the original one.

Look up Colorado, and you may witness the birth of a new meteor shower late Friday night. That’s when the Earth passes through the orbit of a comet named Linear.

The shower’s name is a tongue twister: Camelopardalids. It’s named after the giraffe constellation.

As new restrictions on methane emissions for Colorado’s Oil and Gas Industry begin, a collaborative study by the National Oceanic and Atmospheric Administration, the University of Colorado and the Cooperative Institute for Research in Environmental Studies reveals those emissions are three times as high than originally thought.

For the third year in a row, only students and staff will be allowed on the main campus at the University of Colorado-Boulder. The move is in favor of deterring the mass consumption of pot on what has become known as 420 - or April 20 as it's found on the calendar.
