Dr. Clay Sherrod’s astronomical studies began, soon after his Ph.D. work, in 1970 with the Arkansas Sky, Inc., his private non-profit and educational research and educational program. Although now retired, the work, publications and outreach from him via the Arkansas Sky Observatory ranks among the top in private non-profit facilities.
In his second appearance on the show, Clay and I talked about his latest book which covers the entire spectrum of the change in the Earth’s climate. We noted that climate science has deep roots into the planet’s history and is based on the scientific method. Not everyone speaks the language of science, and so it’s important to identify authoritative sources that can be trusted. We tried to cover as many aspects as we could to deliver a broad picture of the perils facing the Earth.
The internet infrastructure is vulnerable to climate change. The fiber optic cables that ferry data can handle some water damage, but they weren’t meant to be permanently underwater.
…within the next 15 years, in a scenario that projects about a foot of sea level rise by then, 4,067 miles of fiber conduit cables are likely to be permanently underwater. In New York, Los Angeles, and Seattle, the rising seas could drown roughly 20 percent of all metro fiber conduit. These are the lines that physically ferry our Internet traffic from place to place.
Another 1,101 “nodes”—the buildings or places where cables rise out of the ground, which often house computer servers, routers, and network switches to move our data around—are also expected to be swamped.
Get a free Nomad Lightning cable when you donate to the company’s Carbon Fund fundraising event. The minimum donation is US$5, which the company will use to plant trees. This is a steal because the cable on offer is normally US$24.95.
Every dollar donated plants a tree in Acre, a region of Brazil, that is being devastated by deforestation. We want to try to reverse this. Every ten trees planted captures around one ton of C02. Learn more about the project.
It adds a ton of content to the game, like a Diplomacy victory, new civilizations, and climate change.
Jun Kamei, graduate of the Royal College of Art, designed artificial gills using 3D printing. They consist of a gill and a respiratory mask, and it lets people breathe underwater. Mr. Kamei has built a working prototype, and it successfully extracts oxygen from water, and releases carbon dioxide back out. Right now it doesn’t product enough oxygen for a human though. His idea was that artificial gills would be essential in the future when the ocean rises due to climate change.
By 2100, a temperature rise of 3.2 degrees celsius is predicted to happen, causing a sea-level rise affecting between 500 million and three billion people, and submerging the megacities situated in the coastal areas.
Amy Harder covers energy and climate change for Axios. She writes a weekly column called the Harder Line that reports on trends, has exclusive scoops and analyzes the news driving the debate about energy and climate. Her coverage includes congressional legislation, regulations, lobbying, and international policy actions affecting the United States. Amy holds a B.A. in Journalism with honors. In our interview, I asked Amy about some of the most important issues of her coverage: what is “clean coal,” how does global warming affect climate, do all conservatives deny global warming, what is a good website for scientific information, what is her workday like, and what could scientists do to better to communicate with the public? Come meet and listen to the reporter who has a terrific grasp of these important topics.
Dr. Kiki Sanford is a neurophysiologist with a Ph.D from U.C. Davis. She’s a popular science communicator and creator of This Week in Science (TWIS) podcast and radio show. This is her third appearance on Background Mode. In this episode, Kiki and I once again get geeky with science: an in-depth discussion of 1) Whether it’s a bad idea for our AI agents to have human names, 2) How attitudes about some science affects all science budgeting, 3) The wholistic system effects of climate change, 4) A fascinating discussion about the human microbiome and how the digestion of key nutrients affects whole body health and 5) How astronomers use Pulsars to detect gravitational waves. Kiki has a special way of inspiring one to learn about … everything, so don’t miss this very special guest.
Curious what the planet would look like if all the world’s ice melted? Let’s just say the topic has been on my mind lately. National Geographic did the math, with pictures to help us wrap our heads around it. If all the world’s ice melted—an extreme eventuality that would require thousands of years—sea levels would rise an estimated 216 feet. Unsurprisingly, what we know as “coast” today would become “offshore.” In North America, the Atlantic seaboard is gone, as is Florida. In my novel (set in 2139), the Philly Bay is a thing, but that was based on a model of just 22 meters (72 feet) in sea levels rising. In Nat Geo‘s more extreme model, the Central Valley in California becomes a giant bay. San Diego goes bye, bye, as does a little town in Texas called “Houston.” Nat Geo has detailed maps of all the continents, including the desert formerly known as North Africa, the desert formerly known as Australia, and parts of China that are currently home to some 600 million people. As noted above, this map represents the ultimate extreme of global warming, including melted Antartica ice sheets that have survived previous warming periods. The point, though, is that it’s fascinating to see what it might look like.
