Zorro shares a report from The Guardian: One in four people in Silicon Valley are at risk of hunger, researchers at the Second Harvest food bank have found. Using hundreds of community interviews and data modeling, a new study suggests that 26.8% of the population -- almost 720,000 people -- qualify as "food insecure" based on risk factors such as missing meals, relying on food banks or food stamps, borrowing money for food, or neglecting bills and rent in order to buy groceries. Nearly a quarter are families with children. "We call it the Silicon Valley paradox," says Steve Brennan, the food bank's marketing director. "As the economy gets better we seem to be serving more people." Since the recession, Second Harvest has seen demand spike by 46%. The bank is at the center of the Silicon Valley boom -- both literally and figuratively. It sits just half a mile from Cisco's headquarters and counts Facebook's Sheryl Sandberg among its major donors. But the need it serves is exacerbated by this industry's wealth; as high-paying tech firms move in, the cost of living rises for everyone else.

The scale of the problem becomes apparent on a visit to Second Harvest, the only food bank serving Silicon Valley and one of the largest in the country. In any given month it provides meals for 257,000 people -- 66m pounds of food last year. Because poverty is often shrouded in shame, their clients' situations can come as a surprise. "Often we think of somebody visibly hungry, the traditional homeless person," Brennan said. "But this study is putting light on the non-traditional homeless: people living in their car or a garage, working people who have to choose between rent and food, people without access to a kitchen."

According to a new analysis of the most realistic climate models to date, global temperature rise by 2100 could be 15 percent higher than the highest projections from the United Nations' Intergovernmental Panel on Climate Change (IPCC). What this means is that cuts in greenhouse gases like carbon dioxide (CO2) will have to be even greater than expected to meet the Paris climate target of keeping global warming to less than 2 degrees Celsius. Motherboard reports: The world is a long way from making sufficient emission reductions to meet the Paris climate targets to begin with -- nevermind cutting out another 15 percent. But there's some good news, too. Both rich and poor countries have begun to move away from coal and oil, the two biggest CO2 sources, according to many energy analysts. Patrick Brown is a researcher at the Carnegie Institution for Science in Pasadena, California, a co-author of the study published Wednesday in Nature. "Our results imply 15 percent less cumulative emissions than previously calculated [are needed] in order to stay below 2 degrees Celsius," he told me. Brown and co-authors focused on finding out what future warming might be, using only the climate models that best replicate observations over the last 15-20 years. On a business-as-usual emissions trajectory, they found that the mean global temperature rise would be 4.8 degrees Celsius by 2100, compared to the IPCC estimate of 4.3 degrees Celsius. The latter estimate is considered catastrophic for our planet, and would lead to sea level rise of over 30 feet, potentially putting the homes of 600 million people underwater.
