California’s forests are in rapid retreat, which bodes ill for the future.
Using satellite data, researchers from the University of California, Irvine found that trees in the state’s mountainous regions declined 6.7 percent between 1985 and 2021 thanks to wildfires, drought and other climate-related sources of stress.
The U.S. national drought early-warning information system, called NIDIS, gave a rundown Thursday on when much of the Southwest will experience conditions that heighten the potential for wildfire.
Drought is one of the main drivers because less water means drier soils, drier plants and drier air, all conditions that fuel wildfire.
California likely will have an energy shortfall equivalent to what it takes to power about 1.3 million homes when use is at its peak during the hot and dry summer months, state officials said Friday.
Threats from drought, extreme heat and wildfires, plus supply chain and regulatory issues hampering the solar industry will create challenges for energy reliability this summer, the officials said. They represented the California Public Utilities Commission, the California Energy Commission, and the California Independent System Operator, which manages the state’s energy grid.
Flood, fire, and drought fueled by climate change could take a massive bite out of the U.S. federal budget per year by the end of the century, the White House said in its first ever such assessment on Sunday.
The Office of Management and Budget assessment, tasked by President Joe Biden last May, found the upper range of climate change’s hit to the budget by the end of the century could total 7.1% annual revenue loss, equal to $2 trillion a year in today’s dollars.
Already diminished by drought and extreme heat, California’s water supply will face yet another peril as wildfires continue to incinerate ever larger areas of forested land, according to new research.
In a UCLA-led study published Monday in the journal Proceedings of the National Academy of Sciences, researchers determined that increasing forest fire activity is “unhinging” western U.S. stream flow from its historical predictability. In areas where more than a fifth of the forest had burned, stream flow increased by an average of 30% for six years after the fire.
The American West’s megadrought deepened so much last year that it is now the driest in at least 1,200 years and is a worst-case climate change scenario playing out live, a new study finds.
A dramatic drying in 2021 — about as dry as 2002 and one of the driest years ever recorded for the region — pushed the 22-year drought past the previous record-holder for megadroughts in the late 1500s and shows no signs of easing in the near future, according to a study Monday in the journal Nature Climate Change.
When weather patterns and conditions develop that fuel extreme fire behavior, the National Weather Service issues what it calls a “Red Flag Warning.” In response, firefighters rapidly shift resources, beef up staffing and alert nearby communities. It’s an all-hands-on-deck moment to prepare for the worst – one we’ve become increasingly familiar with, even in winter months.
Santa Ana winds returned to Ventura County this week, bringing back dry, breezy and warm conditions but little fire risk.
Peak Santa Ana wind season typically runs from October through January, and without enough rain, fire season can drag on. This year, however, December storms drenched the region, dampening the threat of large wildfires.
Jason Kraling sank his fingers deep into the spongy soil on Mount Laguna Saturday and pulled out a fistful of dead leaves, brittle pine needles, shards of wood and rich brown soil.
“Look at how moist this is,” said Kraling, a fire battalion chief with the U.S. Forest Service. “We’ve gotten a reprieve from how dry things were last summer. It’s a good time for prescribed burns.”
When a fire started spreading quickly in Boulder County, Colorado, on December 30, destroying nearly 1,000 homes as residents fled, the ground was dry. This was unusual: Boulder typically gets around 30 inches of snow between September and December. But last year, it had only a total of 1.7 inches over the same period before heavier snow finally started falling on December 31—too late to save the neighborhoods that burned.
