How Blockchain Could Boost Clean Energy

By Jeremy Deaton

Bitcoin, the much-hyped cryptocurrency, made headlines recently for driving a surge in power use. Around the globe, digital entrepreneurs are 'mining' bitcoins by solving complex math problems, using supercomputers to get the job done. Those supercomputers use a ton of power, which largely comes from coal- and gas-fired power plants spewing gobs of carbon pollution.

But while hackers wreak havoc on the climate, blockchain, the bleeding-edge technology behind bitcoin, could one day help clean up the mess. Climate wonks say blockchain has a role to play in the clean-energy economy, helping homeowners sell electricity, allowing businesses to trade carbon credits, and making it easier for governments to track greenhouse gas emissions.

Post-Fire Landslide Problems Likely to Worsen: What Can Be Done?

By Lee MacDonald

Birders Get a First Look at How 2017 California Wildfires Affected Wildlife

By Matt Blois

A neighbor knocked on Rick Burgess's door at about 9:30 p.m. to tell him a fire was coming towards his home in Ventura, California. When he looked outside he saw a column of smoke, and the hills were already starting to turn orange. He loaded up his truck with a collection of native plants he was using to write a countywide plant guide, and barely had enough time to get out.
