LA Paints Its Streets White To Keep The City Cooler

September 18th, 2017 | by Guest Contributor

While politicians elsewhere waffle on climate change, officials in Los Angeles are tackling the problem head on with a radical plan to lower the temperature of the city. Mayor Eric Garcetti intends to cut the average temperature in LA by 3 degrees F over the next two decades. As part of that effort, LA streets are getting a new coat of paint


Urban Trees Protect Buildings From High Winds, Cold Temps, & Air Pollution

September 17th, 2017 | by Guest Contributor

Scientists have learned that urban trees — even just a single tree — can help homes and office buildings save energy by blunting the chilling power of a stiff wind. Trees keep pedestrians more comfortable when they stroll down the street, and they help lower building heating costs by reducing wind pressure. Even trees without leaves can help slow the wind down


How Food Waste Turned A Barren Landscape In Costa Rica Into A Lush Forest

September 16th, 2017 | by Guest Contributor

Orange isn’t just the new black. It’s also the new green. Twenty years ago, an orange juice producer dumped thousands of tons of orange peels and pulp onto a barren section of a Costa Rican national park, which has since transformed into a lush, vine-laden woodland. The shift is a dramatic illustration of how agricultural waste can regenerate a forest and sequester vast sums of carbon — for free.


Your Rush-Hour Commute Is Not Just Frustrating, It’s Also Making You Sick

September 15th, 2017 | by Guest Contributor

For millions of Americans, the rush-hour commute is more than just frustrating. It’s also dangerous, exposing drivers to unsafe levels of air pollution. Rolling up the windows won’t solve the problem. An ongoing study in Atlanta has found that people are exposed to more pollution sitting in the driver’s seat than they would be watching traffic on the side of the road


Climate Change Is Threatening The Bees That Pollinate Coffee Plants

September 15th, 2017 | by Guest Contributor

The best coffee grows in the mountains, where it is cool. It needs low temperatures to thrive, which is why growers often put shade trees in their fields. But the mountains are getting hotter. And the higher you go, the less room there is to grow coffee. This is one reason scientists predict coffee will suffer in a changing climate.


Climate Change Lawsuits Are Increasingly Showing Up In Court

September 15th, 2017 | by Guest Contributor

When it comes to climate change policy, don’t underestimate the power of the courts. That’s the message from new research that analyzes the growing — but under-recognized — role of the judiciary in the fate of climate change regulations, and the increasing influence of science in climate litigation


Low-Income Communities Were The Hardest Hit By Hurricane Harvey

September 14th, 2017 | by Guest Contributor

Low-income families are more likely to live in flood-prone areas with deficient infrastructure. Hurricane Harvey is yet another example of this pattern. While large parts of Houston flooded, low-income neighborhoods fared worse than wealthier areas


The Network Effect, Robotaxis, & Tesla

September 10th, 2017 | by Guest Contributor

We all know that, when a new technology becomes established, there are winners and losers. However, the picture is more complex: some companies will be small winners and others will be big winners. Where a particular company ends up depends not only on the quality and popularity of its products or services, but on where it fits into the overall market — its position on the “value chain.”


Electric Cars Coming Quickly, Will Disrupt Bunch Of Industries, JP Morgan Forecasts

September 9th, 2017 | by Guest Contributor

By now, everyone who’s paying attention understands that fossil fuel vehicles are going to be replaced by electric vehicles. However, there’s a wide gulf of disagreement about the timeline. Those who make their living in the oil and auto industries tend to see the transition happening in their grandchildren’s time, while some in the EV and renewable energy fields predict that it will all be over by
