The World's Largest Earth Science Experiment: Biosphere 2

Scientists wanted to know if we could replicate the Earth's ecosystems, so in the Sonoran desert outside of Tucson, Arizona they built a three-acre closed-system environment designed to do just that. Known as Biosphere 2 (Biosphere 1 is the Earth), the project was started back in the late 1980s. The idea was to test if we could re-create the Earth's ecosystems in a closed environment to help people to be able to live in space for an extended amount of time.

The project has had a rocky past. In the early 90s, eight brave souls pledged to live in Biosphere 2 for a full two years. "All of their food, water and amenities had to be obtained from inside the Biosphere," says PBS' The Good Stuff. The project ended up hitting a number of stumbling blocks. Oxygen levels got so low halfway through the first year that they had to put more in over fear for the safety of the Biosphere residents. The media deemed the project a failure. A second mission began in 1994, but ended only six months later due to mismanagement and to the fact that two crew members sabotaged the project.

But John Adams, deputy director of Biosphere 2 doesn't see those projects as failures—merely learning processes. "What they did learn, and in my opinion the single most important lesson, was just how little we truly understand Earth's systems," says Adams.

Although people don't live there anymore, the ecosystems have been growing for more than 20 years now, and researchers have been able to learn a lot from the project. In fact, although it was theorized for a long time, ocean acidification "was first demonstrated on a large-scale by researchers from Columbia University at Biosphere 2." And now the University of Arizona is getting ready to conduct the world's largest Earth sciences experiment at Biosphere 2.

Worldwide Clean Energy Investments Hit $333.5 Billion Last Year

Global investment in renewable energy hit $333.5 billion in 2018, the second-highest on record, according to a new analysis from Bloomberg New Energy Finance (BNEF).

That's a 3 percent jump from 2016 and 7 percent short of the $360 billion record set in 2015.

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

Several weeks after a series of wildfires blackened nearly 500 square miles in Southern California, a large winter storm rolled in from the Pacific. In most places the rainfall was welcomed and did not cause any major flooding from burned or unburned hillslopes.

But in the town of Montecito, a coastal community in Santa Barbara County that lies at the foot of the mountains blackened by the Thomas Fire, a devastating set of sediment-laden flows killed at least 20 people and damaged or destroyed more than 500 homes. In the popular press these flows were termed "mudslides," but with some rocks as large as cars these are more accurately described as hyperconcentrated flows or debris flows, depending on the amount of sediment mixed with the water.

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.

Rover Pipeline Spills Another 150,000 Gallons of Drilling Fluid Into Ohio Wetlands

Energy Transfer Partners' troubled $4.2 billion Rover pipeline has spilled nearly 150,000 gallons of drilling fluid into wetlands near the Tuscarawas River in Stark County, Ohio—the same site where it released 2 million gallons in April.

The 713-mile pipeline, which will carry fracked gas across Pennsylvania, West Virginia, Ohio and Michigan and Canada, is currently under construction by the same Dallas-based company that built the controversial Dakota Access pipeline.

Large Dams Fail on Climate Change and Indigenous Rights

Brazil has flooded large swaths of the Amazon for hydro dams, despite opposition from Indigenous Peoples, environmentalists and others. The country gets 70 percent of its electricity from hydropower. Brazil's government had plans to expand development, opening half the Amazon basin to hydro. But a surprising announcement could halt that.

World's Largest Money Manager: Companies Must Respond to Social and Climate Challenges

The world's largest publicly traded companies must take a more active role in solving social issues or face blowback from investors, the CEO of BlackRock said Tuesday.

"To prosper over time, every company must not only deliver financial performance, but also show how it makes a positive contribution to society," Laurence Fink wrote in his annual letter to CEOs of companies in which BlackRock invests. BlackRock is the world's largest money manager, with more than $6 trillion in assets.
