US Navy Acknowledges Rising Toxic Groundwater Threat at SF Superfund Site

The U.S. Navy has acknowledged that in just over a decade, potentially toxic groundwater could surface at a Superfund site at Hunters Point Naval Shipyard in San Francisco. The report comes as the city plans to build thousands of homes, retail, and over 340 acres of parks and open space at a highly complex and ongoing cleanup effort.

Want to accelerate climate action? Show people real-life benefits

In this opinion piece from POLITICO, the writer suggests that rather than leading with data and science to promote climate action and public support, climate resilience advocates should lead with issues people care most about like the economy and housing with climate co-benefits embedded in the solutions. Framing energy efficiency and decarbonized housing as means for household savings and job creation will accelerate climate policies, public support, and action.

The human cost of climate-related disasters is acutely undercounted, new study says

new study published in Nature Medicine looks directly at the human health impacts from severe weather like hurricanes, floods, and intense storms. Using Medicare records before and after weather disasters that incurred more than $1 billion of damages from 2011 to 2016, researchers found that six weeks after a storm, the death rate in counties with the greatest destruction was 2 to 4 times higher than in less impacted areas.

You’re probably underestimating the willingness of your fellow citizens to act on climate

According to a new survey of nearly 130,000 people in 125 countries, nearly 70% of the global population would give up 1% of their household income to stop climate change, which is roughly congruent with the estimated cost of effective climate action. However, people also think just 43% of their fellow citizens would be willing to do the same – a 26-percentage-point gap. In every country the willingness of fellow citizens to fight climate change is systematically underestimated.

Artificial Intelligence Maps the Contours of Climate Change Skepticism in America

A recent University of Michigan study reveals that close to 15% of Americans deny that climate change is a reality. The study, found here:, uses social media data analyses and artificial intelligence to measure climate change denial in the digital space. The study maps belief and denial rates across states and counties. Both climate change belief and skepticism track along factors such as geography and socioeconomics.

What is an atmospheric river? With flooding and mudslides in California, a hydrologist explains the good and bad of these storms and how they’re changing

Atmospheric rivers occur all over the world, forming narrow channels of intense moisture transport in the sky. They start over warm water, typically tropical oceans, and are guided toward the coast by low-level jet streams ahead of cold fronts of extratropical cyclones. Along California, the Pacific Ocean serves as the reservoir of moisture for the storm, and the mountain ranges act as barriers, producing rain and snow on the western sides of the coastal ranges and Sierra Nevada.

Six Ways Inequality Holds Back Climate Action

Cutting greenhouse gas (GHG) emissions is critical to mitigating the effects of global climate change. The fundamental challenge for the world’s nations is setting and achieving GHG emission reduction targets. This not only requires governmental policy and economic paradigm shifts, but also behavioral changes particularly for wealthy individuals and entities. According to Oxfam, globally, the richest 1% emit as much CO₂ as the poorest 66% combined.

America’s Deadly Heat Isn’t (Officially) a Major Disaster

There has been a drastic increase of heat-related mortality in the US over the last 30 years. This disproportionately exposes poorer, nonwhite people, and the elderly. The emergence of extreme heat as a climate hazard shows the need for more nuanced cost-benefit metrics, social vulnerability analyses, and federal guidelines to ensure disaster response and preparedness funds are available to local jurisdictions.

Global greenhouse gas emissions at all-time high, study finds

Scientists warn of “unprecedented” levels of global heating due to worldwide all-time high release of greenhouse gas emissions. The established “carbon budget” which is amount of carbon dioxide that can be released into the atmosphere yet remain within 1.5C above pre-industrial temperatures, is in danger of being surpassed by the end of the decade.

‘I can taste the air’: Canadian wildfire smoke spreads hazardous haze at home and in the US

Wildfires throughout Canada have displaced over 20,000 people and are making air quality hazardous in many of its major cities and in the US. Airports delayed flights due to visibility concerns in New York, Philadelphia, and Washington DC. This summer projects to be the worst fire season in Canadian history. Pictures of the haze in New York City are reminiscent of those eerie San Francisco Bay Area skies in 2020.
