The $227 billion budget proposed on Friday by Gov. Gavin Newsom includes $4.1 billion in spending on a suite of environmental initiatives meant to fight climate change, gird California against devastating wildfires, reduce smog, and bolster the adoption of clean vehicles on the state’s roads.
On a stormy day, 1 billion gallons of water can rage down the river crossing from Tijuana to San Diego.
None of that water is captured for reuse now among the two desert cities it splits, which are regularly prone to drought, because it’s considered polluted by sewage spills on the Mexican side. If successfully recycled, that water could prove to be valuable as the Southwest grows more water-uncertain due to climate change.
Beside a river that winds through a mountain valley, the charred trunks of pine trees lie toppled on the blackened ground, covered in a thin layer of fresh snow.
Weeks after flames ripped through this alpine forest, a smoky odor still lingers in the air.
The fire, called the East Troublesome, burned later into the fall than what once was normal. It cut across Rocky Mountain National Park, racing up and over the Continental Divide.
Efficient water use is an important responsibility that comes along with the benefits of living in San Diego County’s beautiful Mediterranean climate.
No matter whether your landscaping is just a few square feet alongside a small front porch, or covers many acres on a luxury estate, San Diego County residents have learned to embrace sustainability as a central principle for creating or renovating their landscapes. Irrigation is among the highest uses of water for most homeowners.
Climate concerns took a bit of a backseat in 2020. These are the local plans and problems that policymakers might turn their attention to in 2021.
There is a myth about water in the Western United States, which is that there is not enough of it. But those who deal closely with water will tell you this is false. There is plenty. It is just in the wrong places.
Deltas globally adjust with changes and fluctuations in external conditions, internal dynamics, and human management. This is a short history of big changes to California’s Sacramento-San Joaquin Delta in the past and present, and its anticipated future. This history is important for understanding how many of the Delta’s problems have developed, changed, and continue to change.
Beside a river that winds through a mountain valley, the charred trunks of pine trees lie toppled on the blackened ground, covered in a thin layer of fresh snow. Weeks after flames ripped through this alpine forest, a smoky odor still lingers in the air.
The fire, called the East Troublesome, burned later into the fall than what once was normal. It cut across Rocky Mountain National Park, racing up and over the Continental Divide. It raged in the headwaters of the Colorado River, reducing thick forests to ashes and scorching the ground along the river’s banks.
Parts of the world economy may have been on pause during 2020, dampening greenhouse gas emissions for a while. But that didn’t slow the overall buildup of atmospheric carbon dioxide, which reached its highest level in millions of years.
If anything, research during the year showed global warming is accelerating. Symptoms of the fever include off-the-charts heat waves on land and in the oceans, and a hyperactive and destructive Atlantic hurricane season.
A dry start to California’s water year is reflected in the season’s first snow survey of the Sierra Nevada snowpack. The statewide snowpack is 52% of average for Dec. 30. On average, the Sierra snowpack supplies about 30% of California’s water needs.
“The first snowpack survey of the water year points to California’s climate variability, which is why a diverse water portfolio is needed to provide a reliable supply,” said Goldy Herbon, San Diego County Water Authority senior water resources specialist. “The Water Authority and its 24 member agencies have successfully diversified water sources, and continue to expand those sources, to ensure our supply meets the needs of the region’s 3.3 million people and its $245 billion economy.”
