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.
