Study: NASA Satellites Show Areas Growing Drier, Wetter

By studying more than a decade of measurements recorded by NASA satellites, scientists have documented a striking pattern in places around the world: many wet regions have grown wetter, while a number of dry regions have grown drier.

Researchers examined data from NASA satellites between 2002 and 2014 and found areas that have become wetter included the upper Missouri River basin, the northern Amazon and parts of Africa, as well as other parts of the tropics. Areas throughout the mid-latitudes became drier: in the Middle East and North Africa, parts of India and China, and across much of the southern and western United States, where drought-plagued California and the southern High Plains stood out for especially large losses of water.

The Latest: More Record Highs in Heat-Scorched California

Temperatures have again broken records in California, where a lingering heat wave is on the verge of finally easing.

The National Weather Service says the high in downtown Los Angeles hit 90 degrees on Tuesday, breaking the old record of 88 for the day that was set in 1977. San Diego’s high of 89 was eight degrees above the 1981 record. The airport in San Francisco recorded 72, beating a 2007 high.

The California Drought is Costing You in Ways You Might Not Realize

California’s prolonged drought has visible consequences such as depleted reservoirs and mandatory water conservation rules. But one of the more expensive effects could be buried deep in your electric bill.

The Pacific Institute updated its study on the hidden costs of drought and estimated that Californians have paid an additional $2 billion dollars in electrical bills over the last four years.

Lake Oroville Nearly Half Full, Boating Access Increases

With Lake Oroville nearly half full, California State Parks has announced more boat ramps are open.

The agency stated Bidwell Canyon stage 1 ramps are now open for launching, along with Spillway stage 2 and Lime Saddle, according to a press release.

What Happened to the “Godzilla” El Niño?

Wild weather swings across the globe are caused, in part, by the phenomenon known as El Niño. That’s the warming of the Pacific Ocean that leads to drought in much of Africa, and soaking rain and floods on America’s West Coast.

But in Southern California, it appears that El Niño is temporarily on hold.

One Way the California Drought is Contributing to Climate Change

Climate change intensified California’s current drought, and the drought may be intensifying climate change. A new report by the Pacific Institute finds that the state’s energy portfolio has continued to shift away from hydropower and toward dirtier sources of electricity (CityLab covered its 2015 report on the same subject). That’s led to a 10 percent uptick in carbon emissions from California’s power plants, and an extra $2 billion for ratepayers.

Between 1983 and 2013, hydropower accounted for an average 18 percent of California’s total electricity production. It has never been a perfect energy source: Environmentalists object to characterizations of it as ‘renewable,’ because of the negative impact on river ecosystems that large dams invariably have. But in terms of its emissions, “hydro” is clean as a whistle, as it doesn’t burn fuel to produce energy as does, for example, natural gas. It’s also considerably cheaper than other forms of energy.

Fact & Fiction: Ending California’s Drought

California’s soggy start to winter had many predicting the end of the state’s record drought.

Myths and overstatements popped up like weeds after winter rain.
Some said El Niño’s powerful storms could wash away the drought by spring. Others said the state couldn’t officially declare an end to the drought until reservoirs filled up. And then there were questions about whether an official drought-ending declaration could only come from California Gov. Jerry Brown.

Bay Area Weather: New Radar Better Predicts Just Where and Just How Much Rain to Expect

As a wet and windy storm blows in off the Pacific, a new San Jose-based radar system is watching it with the greatest precision ever, estimating rainfall in individual communities rather than providing a more general Bay Area forecast.

Discrete patches of incoming moisture are detected by a humming “X-band” radar unit on the rooftop of a treatment plant owned by the Santa Clara Valley Water District, predicting precipitation and flood risk with much greater accuracy than current technology. Four more units will be phased in over the next five years for the Peninsula, East Bay and North Bay.

Sierra Snowpack at 99% of Normal with More Powder on the Way

The weather, up to its usual surprises, brought summer sunshine to the Bay Area this week in the dead of winter at the same time that Sierra snowpack figures for Northern California were measured and found to be practically normal.

The snowpack in the northern reaches of the Sierra, which stretches from near the Oregon border to Lake Tahoe, was 99 percent of normal for mid-February, the California Department of Water Resources said. Statewide, the snowpack was 91 percent of normal.

BLOG: 66% of Storm Runoff in California’s Bay-Delta Watershed was Captured in January 2016

Recently, some legislators have been demanding that state and federal agencies – or Congress – overrule the decisions of agency biologists and scientists in order to increase the amount of water pumped out of the Delta, complaining that the state and federal water projects are not capturing most of the water from recent storms. Yet recent analysis by The Bay Institute shows that approximately 66% of the runoff in January 2016 was captured or diverted, with only one third of the unimpaired runoff actually making it through the Bay-Delta estuary. For the period of October 1st to January 31st, 60% of the storm runoff has been diverted or stored. Compare this level of diversions to the prevailing science, which shows that, to maintain a healthy river system, no more than 20% of its flows, on average, should be diverted.
