Data shows that the night sky got, on average, 9.6% brighter every year. For many people, the night sky today is twice as bright as it was eight years ago. The brighter the sky, the fewer stars you can see. If this trend continues, a child born today in a place where 250 stars are visible now would only be able to see 100 stars on their 18th birthday.

Climate models and geologic archives are at odds over whether Earth gradually warmed or cooled over the past few thousand years. Researchers tackle this global "temperature conundrum" in a new paper.

Plunging water levels in Lake Mead and Lake Powell could negatively affect millions of people. The former at one point this year dropped to less than 150 feet from "dead pool" status – when the volume falls to a level so low that water cannot flow downstream from the dam. Andrea Gerlak, professor of geography, development and environment at the University of Arizona, said Lake Mead is "dangerously close" to hitting a low enough elevation for it to stop turning the turbines, and producing electricity. "But, more importantly – if and when Hoover Dam stops producing electricity – it will call into question our very assumptions for how we manage water and energy in the southwestern U.S."

The Arizona Partnership for Climate-Smart Food Crops will promote climate-smart food production practices and help farmers reduce water consumption and carbon emissions.
