A new kind of ultra-reflective white paint, developed by researchers at Purdue University, reflects just over 98% of sunlight and has the potential to cool rooftops and asphalt and even help slow down the effects of climate change.

Satellite data from across California’s landscapes reveal an increase in nitrogen dioxide levels in remote forest areas, and wildfire and soil emissions are likely the reasons why, according to a paper from UC Davis published in the journal Environmental Research Letters.

California’s only native sunfish, the Sacramento perch, was once abundant before invasive species decimated it. As the planet heats up and threatens cold-water game fish, the Sacramento perch may be on the cusp of a comeback, thanks to its ability to tolerate warm water.

The Greater Sacramento Economic Council submitted an application for the Economic Development Administration Tech Hub program that aims to establish a Zero Emission Vehicle innovation asset on the campus of Sacramento State.

California’s leading air regulator acknowledged major roadblocks to meeting its ambitious carbon emissions target for 2030. The hurdles revolve around the feasibility of carbon capture technologies and the state’s flagship climate program, known as cap-and-trade.

The total number of climate change court cases has more than doubled since 2017 and is growing worldwide. These findings, published by the UN Environment Programme and the Sabin Center for Climate Change Law at Columbia University, show that climate litigation is becoming an integral part of securing climate action and justice.

As sea levels rise, many countries are considering a controversial strategy: relocation of communities. A Stanford analysis of planned relocations around the world reveals a blueprint for positive outcomes from an approach often considered a last resort.

State water authorities estimated that 3.8 million acre-feet of water went into depleted underground reservoirs this year—enough for 11 million California households annually. That sounds good, but experts say it will take years of rain and effort from local water agencies to reach sustainability.
