"Desalination plants around the world are pumping out far more salt laden brine than previously believed [...] The salty effluent is a by-product of efforts to extract fresh water from the sea. [...] The brine raises the level of salinity and poses a major risk to ocean life and marine ecosystems. [...] There's been a major expansion of desalination plants around the world over the past few years, with almost 16,000 now operating in 177 countries. It's estimated that these plants produce 95 million cubic metres of freshwater per day from seas and rivers -- equivalent to almost half the average flow over Niagara Falls. But the success of the technology is coming at a price. This new study estimates these plants discharge 142 million cubic metres of extremely salty brine every day, a 50% increase on previous estimates."All challenging and yet therein also lies opportunities, including the mining and refinement of salts, minerals, and metals.

The FT writes about Remittances: the hidden engine of globalisation...
"The number of people in the world who live outside the country of their birth has risen from 153m in 1990 to 270m last year according to the World Bank, swelling global remittance payments from a trickle to a flood. As migration has increased, these financial snail-trails have become one of the defining trends of the past quarter-century of globalisation -- the private, informal, personal face of global capital flows. For many developing economies, it is a lifeline. [...] Some governments have sought to channel remittances into development efforts; Indonesia is the latest country to consider a “diaspora bond” in a bid to tap the savings of its wealthier overseas residents."

Richard Florida writes in CityLab that Maps Reveal Where the Creative Class Is Growing in the US...
"A growing chorus of economists and urbanists suggest that we may be seeing the “rise of the rest,” a result of both increasingly unaffordable housing in established hubs and the improvement of the economies in less-established hubs. [...] The map shows the percentage growth in the creative class from 2005 to 2017. A number of Rustbelt and Sunbelt metros which have previously lagged now show robust growth. Salt Lake City posted the fastest growth, with Pittsburgh and Cincinnati next in line. Las Vegas, which had the smallest creative class share of large metros in 2005, also saw significant growth. Of leading creative class metros, only Seattle and Baltimore registered comparable gains. [...] The even better news is that the creative class -- which often garners the highest paying jobs -- appears to be growing as a percentage of total workforce employment across the board."

Nadia Drake in NatGeo writes Here’s why women may be the best suited for spaceflight...
"Physically and mentally, women have the right stuff for lengthy missions in space. So why send men when you can send just their contributions to the next generation, collected and cryopreserved in tiny vials? Sending an all-female crew and a sperm bank lets a space program economize while also increasing the genetic diversity of the parental pool."

The Sun is a giant thermonuclear reactor in the sky powerbeaming 24x7. A tiny sliver hits the daily rotating Earth and then you have to discount for angles and overcasts. When all's accounted for, here's the resulting worldmap of terrestrial potential for PV or photovoltaic sunpower... Curiously enough, most maps like this only show land incidence. But surely we could float massive solar panels out on swathes of ocean? In fact, perhaps we should hoover up the massive ocean gyres of waste plastic and convert these into floatation for PV paneling.

I'm particularly interested in seeing half of Earth be protected by 2050. Towards this goal, Protected Planet shares the World Database on Protected Areas (WDPA) covering both terrestrial and marine protected areas and tracks progress... The IUCN has a half dozen so-called "Protected Area Management Categories" -- and those are important and worth adding to directly, but I hope we can especially push for enhancement of Category VI "Sustainable Use" with particular eye on private conservancies, land banks, forestry reserves, flood management zones, and potentially even the careful extractions of natural resources. Finally, I hope that we figure out how not to ravage the other half of Earth but rather we green it appropriately (e.g. our cities), share it with nature, and refrain from eco-devastation generally.
Very interesting to see adoption of personal electric vehicles in Europe and Asia. Curious how much of the advantages are State subsidy and tax relief? Norway, for example, offers substantial tax benefits, the right to drive in carpool lanes solo, and free charging, which kind of distorts market action. Also, China has endless ways of State subsidies for both personal and mass transit electrification. Which all may make environmental sense. In any case, here's share and size info from Statista...

Jennifer Chu of MIT News spotlights recent research indicating that Tectonics in the Tropics Trigger Earth’s Ice Ages...
"Over the last 540 million years, the Earth has weathered three major ice ages [each] preceded by tropical “arc-continent collisions” -- tectonic pileups that occurred near the Earth’s equator -- in which oceanic plates rode up over continental plates, exposing tens of thousands of kilometers of oceanic rock to a tropical environment. [The] heat and humidity of the tropics likely triggered a chemical reaction between […] the rocks’ calcium and magnesium […] pulling the [CO2] out of the atmosphere and permanently sequestering it in the form of carbonates such as limestone [cooling] temperatures globally and ultimately [setting] off an ice age."

Luke Kemp at the BBC asks Are we on the road to civilisation collapse?
"If the fate of previous civilisations can be a roadmap to our future, what does it say? One method is to examine the trends that preceded historic collapses and see how they are unfolding today. [...] The collapse of our civilisation is not inevitable. History suggests it is likely, but we have the unique advantage of being able to learn from the wreckages of societies past. [...] We will only march into collapse if we advance blindly. We are only doomed if we are unwilling to listen to the past."
"Collapse is a tipping point phenomena, when compounding stressors overrun societal coping capacity. We can examine these indicators of danger to see if our chance of collapse is falling or rising. Here are four of those possible metrics, measured over the past few decades:"

Together with colleague Ramesh Raskar, I'm co-teaching the AI for Impact seminar this Spring 2019 every Mon afternoon starting Feb 11th from 2:30-4:30a in E15-341, the heart of the MIT Media Lab! Our goal is to bring computational, analytics, and AI techniques to bear on solving problems in the high impact realms of health & wellness, cities & sustainability, across scales of action from each of us as individuals to embracing all of humanity, in both developed and emerging markets alike, all broadly understood. We want to help students identify top AI opportunities for impact and help make progress towards building prototypes, planning action ventures, and/or better understanding the emerging technology and impact trendscape. Formerly known as "Imaging Ventures" or “AI Ventures”, this “AI for Impact” class seeks answers to the question: If you could make almost anything, what's actually most worth making, i.e. what problems are most worth picking? We believe starting with the right problem is 90% of what makes for great projects and ultimately epic, worthy solutions.

Together with colleagues Kate Mytty and Libby McDonald, I'm co-teaching the Inclusive Economies seminar this Spring 2019 every Wed morning starting Feb 6th from 9:30-11:30a in N51-350, the D-Lab classroom area! We explore how innovations and market mechanisms can benefit humanity by rallying impact investments, engaging participants cooperatively, boosting equity and resilience, and broadening prosperity. We look at market mechanisms for maximizing participation, choice, and growth; impact investing approaches which are socially responsible and include metrics that matter; cooperative and mutual ownership structures for shared gains; equitable citizen participation in basic and natural resource wealth; and the role of new technologies and methods towards boosting affordability, accessibility, and overall inclusive prosperity.

Richard B. Alley, Kerry A. Emanuel, Fuqing Zhang write in Science about Advances in weather prediction...
"In recent decades, advances in forecasting have been rapid, arising from improved observations and models, and better integration of these through data assimilation and related techniques. Investment in weather forecasting pays large dividends, ranging from 3 to 10 times the costs. [But] the developing world is especially vulnerable to weather disasters yet is underserved by forecasting."

Roberto Stefan Foa and Yascha Mounk in The Signs of Deconsolidation in the Journal of Democracy share evidence of a global pattern of disaffection with democratic systems...
"Americans’ dissatisfaction with the democratic system is part of a much larger global pattern. It is not just that the proportion of Americans who state that it is “essential” to live in a democracy, which stands at 72 percent among those born before World War II, has fallen to 30 percent among millennials. It is also that [...] a similar cohort pattern is found across all longstanding democracies, including Great Britain, the Netherlands, Sweden, Australia, and New Zealand. In virtually all cases, the generation gap is striking, with the proportion of younger citizens who believe it is essential to live in a democracy falling to a minority."
"What is more, this disaffection with the democratic form of government is accompanied by a wider skepticism toward liberal institutions. Citizens are growing more disaffected with established political parties, representative institutions, and minority rights. Tellingly, they are also increasingly open to authoritarian interpretations of democracy. The share of citizens who approve of “having a strong leader who does not have to bother with parliament or elections,” for example, has gone up markedly in most of the countries where the World Values Survey asked the question -- including such varied places as Germany, the United States, Spain, Turkey, and Russia"

WEForum shares the Human Life Indicator (HLI) proposed by Sergei Scherbov, Simone Ghislandi, and Warren Sanderson as an alternative measure of development solving several problems of the Human Development Index (HDI)...
"The HDI is like a country’s report card. In a single number, it tells policymakers and citizens how well a country is doing. The HDI has been wildly successful in changing the way people think about the development process. However, it still suffers from real flaws. First, it implicitly assumes trade-offs between its components. The HDI also struggles with the accuracy and meaningfulness of the underlying data. Finally, data on different domains may be highly correlated. The HLI looks at life expectancy at birth, but also takes the inequality in longevity into account. If two countries had the same life expectancy, the country with the higher rate of infant and child deaths would have a lower HLI."
