Arizona will be hit harder than most states, a new report says.
The Southwest is heating faster than the rest of the country. Sea levels are rising. Oceans are acidifying. The North Atlantic’s hurricanes are intensifying. Piñon and lodgepole pines are dying.
The U.S. energy advantage is under attack. The shale-gas revolution has spurred billions in new investments and resurrected industries that had left the country.
A University of Arizona researcher is heading a team that wants to learn how climate change affected the evolution of humanlike species.
A Washington, D.C.-based advocacy group has sued the University of Arizona demanding the release of a cache of documents — including two professors’ emails — related to climate change and global warming.
Earlier this year, scientists at the NOAA Mauna Loa Observatory in Hawaii announced a major threshold in the Earth system had been crossed: the concentration of the greenhouse gas carbon dioxide in Earth’s atmosphere has now passed a level not seen in the last 3 million years.
Much of the heat that was supposed to fire up the globe’s air in the past 15 years — but didn’t — has gone into the ocean, a University of Arizona oceanographer said Friday.
Vertebrates would have to evolve 10,000 times faster than they ever have to keep up with the pace of change predicted for their climatic niches in the next century, says a University of Arizona researcher.
Mounting evidence links our region's increase in destructive wildfires to climate change, researchers say.
You just can't out-gloom an environmentalist. The Atlantic invited some luminaries to answer the question "How and when will the world end?" Some contributions were funny. Others simply plausible - a volcanic eruption from underneath Yellowstone National Park is frightfully overdue.
