More people now recognize climate change as the pre-eminent issue of our time, a core focus of resistance, and a source of massive economic opportunities.Imagine looking back and saying, “The Anthropocene Epoch started dangerously, as human activity threatened our future. But that sparked an unprecedented transition that protected our air and water. Every country pulled together to ensure a livable world. Our confidence, ingenuity, and resolve made it humanity’s greatest triumph.”After the U.S. government walked away from its international climate commitments, other key players including companies, cities, and states – where much of the action was already taking place – upped the ante. Policies, legislation, and entrepreneurship increasingly reflect this urgency. Globally, cities and companies are setting timetables to get off fossil fuels. Some are already there! Roadmaps created by Stanford engineer/atmospheric scientist Mark Z. Jacobson and the Solutions Project he co-founded helped make “100 percent renewables by 2050” a meme.But some have privately questioned the goal’s assumptions, research, and feasibility. Now 21 prominent climate scientists have issued a comprehensive public critique in the same Proceedings of the National Academy of Sciences where Jacobson published in 2015. Jacobson’s team gave broad and line-by-line responses, to which the critics responded.This debate highlights the views of experts who support renewables, but believe the electric grid needs a “many of the above” portfolio. To keep the lights on, they say we may long need 20 percent low- or zero-carbon non-renewable baseload capacity. They favor keeping open most atomic plants. They support efforts to develop affordable next-generation nuclear, CCS (carbon capture & sequestration), hot fusion, and LENR (low energy nuclear reactions). They hope these can be deployed at scale in time to make a difference.

A Floating Food Forest In New York City | Modern Cities

New York’s ‘barge-to-table’ floating farm gives city residents without access to farmland the opportunity to pick their own food. As a successful demonstration at Brooklyn Bridge Park comes to end later this week, Mary Mattingly has shed light on an obscure New York City law that prohibits the growing of food on public land, and demonstrated that edible perennial landscapes can help solve food insecurity problems in even the harshest of urban settings.Swale is a public floating food forest built atop a 5,000 square foot barge, currently docked at Brooklyn Bridge Park’s Pier 6. Founded in 2016 by artist Mary Mattingly, Swale allows visitors to harvest herbs, fruits and vegetables for free. The project began as an idea to advocate for food to be grown on some of the 30,000 acres of public land in New York City. Although NYC boasts over 100 acres of community garden space, the City has more than 30,000 acres of park space. Picking one’s own food is illegal on New York City public land, so Mattingly banded together a team of stakeholders to construct a dense garden of edible plants atop a barge- which is technically legal due to a loophole created by waterway common law.

Bike Lanes May Be The Most Cost-Effective Way To Improve Public Health | Co.Exist | ideas + impact

a start!!!

Amazing things happen to a city once people are encouraged to switch to bike commuting: the air quality improves throughout the city, which benefits everyone, not just cyclists. Quieter roads are more pleasant roads to be around, and they’re less congested for those who still insist on driving. And of course riding a bike every day brings all kinds of health benefits to the cyclists themselves.A new study from researchers at Columbia University’s Mailman School of Public Health shows just how big those benefits can be. Per dollar spent, constructing bike lanes is a cheap way to improve public health. For instance back in 2005, New York City spent $10 million on curbing traffic as part of the federally-funded Safe Routes to School program. Sidewalks were widened, bike lanes constructed, and traffic lights re-phased to suit pedestrians. The “net societal benefit” of these changes? The study’s authors estimate it to be $230 million.

A Giant Japanese Toilet Company Is Making A Toilet For The 2.5 Billion People Who Lack One | Co.Exist | ideas + impact

The Japanese toilet giant Lixil counts brands like Grohe and American Standard in its portfolio, and it’s known for fancy, automated johns that some compare to iPhones for engineering quality. But it’s the SaTo (“Safe Toilet”) division of the company that could have the widest impact in the world.SaTo is the name of a low-cost toilet first developed with American Standard, with financial support from the Bill & Melinda Gates Foundation. Designed for parts of the world where there are no sewer systems, the SaTo has sold more than 1 million units so far, encouraging Lixil to think bigger. It’s now turning SaTo into its own division, with a mission to spread cheap-but-effective toilets to the 2.5 billion in the world who still lack them.

Tesla doubles the energy density of its commercial batteries

While Tesla’s solar roof / Powerwall event isn’t until tomorrow, the product that preceded both, its commercial… cousin, Powerpack, has been upgraded and is already shipping to companies. The company says Powerpack 2 has double the energy density than the original model, paired with a new inverter (made at its Gigafactory), that’s apparently the lowest-priced, highest efficiency utility-scale inverter available. Arguably just as important, the new inverter also simplifies the installation process, with several once-separate components now baked into it.Tesla’s blog calls the new system a “a cost-competitive alternative to other traditional utility infrastructure solutions”. It adds that nearly 300 MWh of Tesla batteries have been deployed so far –including complexes in California. Now, where’s the solar part?
