We are tomorrow’s past, so this Thanksgiving give thanks for 2013, a year the future might study more for amusement than edification.
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.
The economy stagnates. Syria burns. Scandals lap at his feet. China and Russia mock him, even as a "29-year-old hacker" revealed his nation's spy secrets to the world. How does President Obama respond? With a grandiloquent speech on climate change.

The following editorial appeared in Monday's Washington Post:
Harvest manager Rachel Nisch goes over details on the harvest board, a budget for plants to harvest and orders to fill, with co-owner C.J. Marks at Sleeping Frog Farms near Benson.
Intern Ben Shonkwiler plants peppers at Sleeping Frog Farms in front of one of six hoop houses installed this year to mitigate hard winter freezes. The 75-acre Sleeping Frog Farms produces fruits and vegetables for Tucson restaurants, a Community Supported Agriculture program and farmers markets.
Co-owner C.J. Marks tears up spring seasonal plants to make way for arugula at Sleeping Frog Farms in the San Pedro River Valley. The farm, about 30 minutes north of Benson, was hit by frost in 2011 and 2013 and lost much of its winter produce.
Some farmers say extreme weather events seem to be more frequent in Southern Arizona, forcing them to adapt.
In February 2011, unusually cold, freezing weather settled in across Southern Arizona for days. At one area store, flowers were draped in ice from some sort of water line or sprinkler problem.
Unusually cold weather in February 2011 caused sprinker pipes to freeze and burst at the Urban League's Project Yes Angel Family Center.
It's more than 3,600 miles from Tucson to the Arctic Circle, but researchers are starting to link some of Tucson's and the country's extreme cold and warm spells over the past few winters to the loss of Arctic sea ice that was caused by a warming climate.
President Obama should spend his remaining years in office making the United States part of the solution to climate change, not part of the problem. If Congress sticks to its policy of obstruction and willful ignorance, Obama should use his executive powers to the fullest extent. We are out …
