Oceanographer John Englander Discusses Sea-Level Rise

John Englander is an oceanographer, consultant, and leading expert on sea-level rise. His broad marine science background, explorations to Greenland and Antarctica, and research provide him the ability to see the big picture of sea-level rise and its societal impacts.

In this clip, John points out that various tipping points appear to be cascading. Some examples he cites include the Arctic sea ice melting quicker. It is responsible for changing weather patterns and could be involved with slowing down the ocean currents.

He points out that the number of people that are vulnerable to flooding as sea-level rises is difficult to define. If sea-level becomes one meter higher or one point one meters higher, the extra 10 centimeters is hard to extrapolate or project onto how many homes would flood. Today, satellite images provide a more accurate picture of the height of the terrain the topography. In prior years, tree canopy looked like land and flooding projections were more conservative. Now, artificial intelligence and machine learning, help us decipher the actual land height and acknowledge that more people are vulnerable to flooding.

He points out that even if we could somehow magically stop all carbon dioxide emissions, we would still have the effects of the heat already stored in the atmosphere. All the strange weather patterns, the fires, and droughts, will not go away immediately even if we could reduce carbon dioxide emissions to zero. Therefore, we have to be more resilient to these extreme weather events.

John works with businesses, governmental agencies and communities to understand the risks of increased flooding due to rising seas, extreme tides, and severe storms, advocating for “intelligent adaptation”.

Microorganisms Bring Eco-Friendly Color To Fashion

More and more these days we’re being urged to go green – to use ethically-sourced products, recycle more and try to reduce our carbon footprint. That awareness has even spread to the fashion industry.

Colorifix, a British biotech startup, uses a synthetic biology approach to produce, deposit, and fix pigments onto textiles. The method of textile dyeing taps into the bright colors of birds and butterflies and has micro-organisms recreate them on fabric, slashing the use of water and heavy chemicals in the process,

“We’re harnessing the ability of microbes, in this case, to be able to deposit and fix a pigment on to fabric.”

–Colorifix Chief Scientific Officer Jim Ajioka

Dyeing with synthetic pigments uses large concentrations of hazardous chemicals such as chromium and heavy metal salts. It also consumes vast amounts of energy and water.

In contrast, Colorifix says its method uses no hazardous chemicals and cuts water use by up to 90% depending on equipment, pigment, and fabric.

Apparel is one of the top-polluting industries. Consumers are increasingly demanding sustainable products and pushing image-conscious retailers to address the environmental impact of their clothes’ full life cycle. The dyeing stage has one of the biggest.

Colorifix expects to launch commercially its 5-ml batches of microbes bulging with color in 2020. Challenges include creating new hues on-demand, maintaining standards of current processes, and keeping costs down.

Colorifix’s backers include H&M, Swiss investment firm Challenger 88, and Cambridge University.

COP25 Starts Monday, December 2nd

UN Climate Change Conference

The UN Climate Change Conference COP25 (2 – 13 December 2019) will take place under the Presidency of the Government of Chile and will be held with logistical support from the Government of Spain. SBSTA 51/ SBI 51 will take place on December 2-13, 2019.

Countries are expected to finalize their climate commitments. The global goal is to stay below the 1.5°C threshold. Global emissions need to be cut by more than 7% every year between 2020 and 2030.
