If tree growth and seed production can’t compensate for the impacts of climate change, California’s trees will face difficulty filling in gaps left by wildfire and reaching areas that are becoming climatically suitable, studies now show.
Fenced hunting preserves have become a flash point over who is to blame for the spread of chronic wasting disease.
In 1979 the Upper Arkansas Water Conservancy District was formed. Since that time innumerable benefits have been provided to the citizens of the district.
Earthquake swarms are ubiquitous in volcanic systems, being manifestations of underlying nontectonic processes such as magma intrusions or volatile fluid transport. The Long Valley caldera, California, is one such setting where episodic earthquake swarms and persistent uplift suggest the presence of active magmatism. We quantify the long-term spatial and temporal characteristics of seismicity in the region using cluster analysis on a 25-year high-resolution earthquake catalog derived using leading-edge deep-learning algorithms. Our results show that earthquake swarms beneath the caldera exhibi...
NationofChange Modern fracking emerged so quickly, faster than its impacts were understood. What is fracking? Fracking is a process of blasting water, chemicals and frac sand deep into the earth to break up sedimentary rock and access natural gas and crude oil deposits. The fracking industry, which has sought to promote the practice as safe and controlled, has preferred the term “hydraulic fracturing.” Fracking emerged as an unconventional, “relatively new” and extremely popular technique only about 20 years ago in the U.S., after advances in technology gave it an unp...
