Nevada-California desert ‘half empty’ of birds after population collapse

Bird populations have collapsed in the desert along the Nevada-California border, and climate change could be to blame, according to a new study by scientists at the University of California, Berkeley. Over the past century, the number of bird species has fallen by an average of 43 percent at survey sites across an area larger than New York state.

Bird species collapse in the Mojave, driven by climate change

Bird populations in the Mojave are plummeting for lack of water, in an imbalance driven by climate change. A new study from UC Berkeley finds shrinking rainfall has led to the loss of more then 40 percent of bird species, in a habitat that relies heavily on birds for basic functions such as pollinating plants and acting as both predator and prey.

California water managers vary in use of climate science: Study finds climate change is projected to shift water supplies

Historically, water managers throughout the thirsty state of California have relied on hydrology and water engineering — both technical necessities — as well as existing drought and flood patterns to plan for future water needs. Now, climate change is projected to shift water supplies as winters become warmer, spring snowmelt arrives earlier, and extreme weather-related events increase.

Commentary: Ignore the climate change deniers. California’s hellish summer really is a grave warning.

In the long, hot, smoky California summer of 2018, as we camp under ash-hued sunset skies, the scariest thought is that the future has arrived, and more intense weather extremes will continue to wreak havoc in years to come.

‘The president’s right’: Interior chief pushes thinning forests to cut fire risk

Interior Secretary Ryan Zinke, touring neighborhoods devastated by the Carr Fire, stepped up the Trump administration’s push Sunday to remove more trees from national forests as a means of tamping down fire risks. “We need to manage our forests, we need to reduce the fuels,” Zinke said as he overlooked Whiskeytown Lake in the vicinity where the Carr Fire began July 23.

Editorial: Where there’s fire, Trump blows smoke

What’s really alarming about President Trump’s preposterous tweets about the California wildfires is not what he gets wrong, which is plenty, but what they say about his stubborn refusal to grasp the basics of climate change and, perhaps worse, his administration’s contempt for the science that is drawing an ever-tighter link between a warming globe and extreme weather events around the world.
