Increasing year-to-year variability in temperature and precipitation that will create greater contrast between drought years and wet years. Severe wildfire seasons like the one that has devastated California this fall may occur more frequently because of climate change.
The answer isn’t as clear-cut as it was this summer, when drought- and heat-stoked fires raged across the Rockies and Pacific Northwest. Instead, a mix of forces are driving the fires in Southern California, and only some of them have a clear connection to global warming.
Every piece of plastic rubbish has a story, so it also makes me wonder about the chain of events that led to that particular item ending up in the deep ocean, and whether any of those events could have been prevented.
Sea level rise and catastrophic coastal flooding could come early to the US Atlantic coast. So sea water in the streets of Florida or drowned towns on offshore islands will not necessarily be blamed upon global warming.
Undertaking a review of more than two dozen national monuments declared since the 1990s is part of the Trump Administration's determination to roll back regulation and open public land to private industry.
Seventy takes us near the end of this century, when predictions from climate models describe terrifying scenarios. If the world as we know it would cease to be in 70 years, people should start to take notice now.
Oil drilling was banned along the entire Sonoma County coast when President Obama expanded Greater Farallones National Marine Sanctuary in 2016. Now the Trump administration is considering reversing that decision.
It will take decades to slow nitrate contamination in groundwater from industrial agriculture in parts of the state of California, so communities are taking matters into their own hands to get clean drinking water.
The ocean is losing oxygen due to nutrient pollution, the effects of climate change, and decreased mixing of marine layers. These are a few ways that could help predict catastrophic loss of ocean oxygen.
Later this year, an army of small swimming robots is set to plumb the mysteries of oceans around the world. Each one will have its own mission, as defined by citizen scientists interested in everything from reefs to "robomussels" that can self-monitor temperature.
Decades after declaring 1,2,3-TCP a carcinogen, California is finally regulating the toxin. But the cost of remediation will be high and communities are turning toward litigation to pay for water treatment.
We've known that the plastics we throw away — empty water bottles and grocery bags, for instance — pollute our oceans. Every year, about 8.8 million tons (8 million metric tons) of this material ends up in the deep blue sea, imperiling marine ecosystems.
Five years after Superstorm Sandy was supposed to have taught the U.S. a lesson about the dangers of living along the coast, disaster planning experts say there is no place in America truly prepared for climate change and the tempests it could bring.
Park visitorship should reflect the state’s “ethnic, age and income diversity” and a state park unit providing a “relevant educational, interpretive, spiritual, cultural, familial, community, and recreational experience”.
Decision time is approaching for the agencies that will have to pick up the nearly $17-billion tab for building two massive water tunnels under the Sacramento-San Joaquin Delta, the heart of the state’s water works.
A controversial California climate program got a shot of good news this month when a study suggested it is successfully reducing the state’s greenhouse gas emissions and providing other environmental benefits on the side.
East Porterville was the hardest-hit community during the drought, when nearly 1,000 people were without water. Efforts to find a long-term fix have been successful but came with a big price tag and some important lessons.
Electric cars and smartphones of the future could be powered by supervolcanoes like Yellowstone after scientists discovered that ancient deposits within them contain huge reservoirs of lithium—a chemical element used to make lithium-ore batteries, supplies of which are increasingly dwindling.
California Atty. Gen. Xavier Becerra plans to announce a lawsuit on behalf of the state that will challenge President Trump’s proposal to build a wall at the U.S.-Mexico border, a project Becerra has called “medieval.”
One of the hardest parts of building Nomadix has been reminding ourselves to slow down. We really want to be able to make the right decisions that align with our values, not just growth rates or profit margins.
And because it is nearly impossible to carve out more Central Parks in dense cities across the country, linear parks are an excellent way to add green space to urban areas. Their long and winding shape can provide greater access to parks for more residents.
The Environmental Protection Agency has so far found perchlorate in 45 states, tainting water supplies of roughly 16 million Americans. Yet, there is no mandate that water utilities outside of California and Massachusetts test for the toxic chemical or let residents know when it’s in their tap water.
In 2006, California voters approved Proposition 84, a bond measure authorizing $5.4 billion in spending on projects to improve parks, natural resource protection, and water quality, safety, and supply. Most of that money has now been spent.
Biodiversity also exists in many other places. More than half of the people on Earth live in cities, and that number is growing, so it is especially important to understand how biodiversity patterns occur in our man-made environments.
Without oceans, there would be no life on earth as we know it. But they are under more stress than ever, thanks to overfishing, pollution, and climate change. This World Oceans Day, here are six things you can do to save the seas.
Harvey and Irma are sad reminders that policy matters. At a time when damage from climate change is escalating, we need sensible policy in Washington to protect the citizens of this country, both by reducing future climate change and preparing for its consequences.
With millions of tons of plastic waste being dumped into the sea every year and barely any ocean area free of such pollutants, the environmental impact on marine life and species is tremendous. Take a look at the hazardous effects of plastic pollution on our oceans.
Drought conditions continue for thousands of rural residents in the San Joaquin valley who rely on groundwater. And the race to dig deeper wells is a losing game for small communities and those on private wells.
Climate change may not have “caused” Hurricane Harvey, but it seems likely that warming temperatures — the consequence of man-made greenhouse gases trapping heat in the atmosphere — exacerbated the storm conditions.
In the two minutes it took you to read this article, more than 60,000 pounds of plastic were dumped into our oceans. That plastic could very well have profound health consequences for you and the ones you love.
Rita Sudman is longtime observer of the California water, and even led the Water Education Foundation. In 2016, she co-authored "Water: More or Less." In an interview with ABC10, Sudman talked about her book and the future of California's water policy.
More than 1 million people in the region have been exposed to unsafe drinking water in recent years from pesticides, arsenic, nitrate and uranium. And many communities also face multiple environmental health threats.
A team of writers and researchers led by American environmentalist Paul Hawken has just published Drawdown, a comprehensive plan to scale back the world’s greenhouse gas emissions. The book offers hope that real solutions within reach.
In a state that prides itself as a global leader in protecting the environment, recycling rates for beverage containers have dropped to their lowest point amid the continued closure of centers that pay for bottles and cans and the fallout from changes to California's recycling program.
Plastics recycling, ocean pollution and program investments were among the sustainability topics at the first Plasticity Forum in California. While noting that the U.S. is far from ideal on plastics recycling, California is so far ahead of other areas.
