The Gila River Indian Community Council in September approved plans to reclaim an 80- to 100-square-mile section of the Gila River and floodplain from invasive salt cedar, or tamarisk.
Removing invasive salt cedar reduces the risk of wildfires, but it also offers a chance to restore native plants and wildlife.
Bigger, hotter wildfires — and more of them — are becoming the new normal, and a combination of climate change, sub-par fire management and budget limitations are to blame, says an October 2017 National Wildlife Federation report.
The years 2015 and 2016 saw record levels of excess carbon dioxide in the atmosphere, even though human carbon emissions have stabilized in recent years. Now, scientists think they know why.
Improved imaging of the Earth’s interior has unlocked new subsurface mysteries, including an area 600 miles (1,000 kilometers) down where the mantle’s usual flow pattern changes.
Now, at a lab bench on the planet’s surface, a team of researchers might have found the reason why.
The most extreme monsoon storms are growing more intense in central and southwestern Arizona, according to a study by the University of Arizona and the National Autonomous University of Mexico.
The findings conform to patterns expected under climate change conditions. Indeed, experts have already observed this effect.
