University of Arizona biology professor Brian Enquist is investigating how changes in global temperature will affect our forests. His study group is connecting with other researchers around the world to make detailed measurements of trees and soils to predict the impact of climate change on the Earth's ecosystems.
A study conducted by Mexican researchers and international conservation groups has found microplastic in the stomachs of 20 percent of fish tested at three Mexican ports, including one in the Sea of Cortez.
Trees in Arizona and other areas of the West have been hit hard many factors including wildfires and the bark beetle. Now, new research indicates that climate change in the form of extreme and inconsistent precipitation totals is also hurting some tree species.
The Navajo Transitional Energy Company — or NTEC — purchased three bankrupt coal mines in Wyoming and Montana this week. It’s a move that’s been met with criticism from some who want the Navajo-owned company to move toward renewable energy — and away from coal.
The National Park Service approved a plan Wednesday to protect endangered fish in the Colorado River below Glen Canyon Dam. It will encourage what it's calling "an incentivized harvest" of brown trout, a non-native predator whose population has grown too big.
Tangier Island is disappearing. The tiny community in the middle of the Chesapeake Bay is likely to be the first town that will be entirely lost to climate change as water levels rise and the island turns to marsh.
Phoenix and Maricopa County are among the fastest growing areas in the country. With that growth has come changes to the physical landscape of the city, new business opportunities in the valley and efforts to revitalize some neighborhoods.
This year marks the fifth annual Jaguar Day Festival in southern Sonora, Mexico. It’s a celebration that brings awareness to the endangered jaguar in this region. The town of Álamos, Sonora, is hosting its annual Día del Jaguar celebration this Friday and Saturday.
The Mexican government says it’s increasing enforcement efforts in the Sea of Cortez to prevent illegal fishing nets from harming an endangered porpoise. It comes a week after local fishermen announced they would buck a fishing ban this shrimp season. But the government's plan doesn't address their concerns.
It’s tough to find a river in the West that still behaves like a western river. The relatively free-flowing Yampa River in northwestern Colorado is unique. The people who depend on it are wondering how best to protect the river as the West’s water grows more scarce.
Acciona and Tuto Energy’s Puerto Libertad facility is one of the largest solar installations in Latin America. With over 1.2 million panels, the 405-megawatt plant generates enough power for over half a million Mexican homes, according to a company release.
Every year, thousands of animals are crushed trying to cross a highway just south of the U.S.-Mexico border in Sonora. It’s a major impediment to jaguars, ocelots and black bears whose survival depends on free movement through borderlands. Some researchers are working to create wildlife crossings that could mitigate the dangers of the road. → Special Report: Protecting The Northern Jaguar
Katharine Hayhoe never meant to become a climate scientist. In fact, in college she started out studying astrophysics, but she needed one more class to finish her degree, and she found a new one over in the geography department on climate science.
