March 2017 in Review

Most frightening stories:

  • La Paz, Bolivia, is in a serious crisis caused by loss of its glacier-fed water supply. At the same time we are losing glaciers and snowpack in important food-growing regions, the global groundwater situation is also looking bleak. And for those of us trying to do our little part for water conservation, investing in a residential graywater system can take around 15 years to break even at current costs and water rates.
  • Trump admires Andrew Jackson, who I consider a genocidal lunatic and the worst President in U.S. history.
  • Fluoridated drinking water could eventually be looked back on as a really stupid idea that damaged several generations of developing brains, like leaded gasoline. Or not…I’m not sure who to believe on the issue but caution is clearly warranted.

Most hopeful stories:

  • A new political survey says there is a chance that a majority of Americans are not bat-shit crazy. Which suggests they might not be too serious about Steve Bannon, who believes in some bat-shit crazy stuff. There are a number of apps and guides out there to help sane people pester our elected representatives when they fail to represent our interests.
  • South Korean women are projected to be the first to break the barrier of an average life expectancy of 90, with a 50% probability of this happening by 2030.
  • Advanced power strips can reduce the so-called “vampire loads” of our modern electronic devices that are never really off.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

  • This long NASA article first gets you excited about the possibility of life on eight new planets it has just discovered, and then throws cold water (actually, make that lethal X-rays) all over your excitement.
  • Bill Gates has proposed a “robot tax”. The basic idea is that if and when automation starts to increase productivity, you could tax the increase in profits and use the money to help any workers displaced by the automation. In related somewhat boring economic news, there are a variety of theories as to why a raise in the minimum wage does not appear to cause unemployment as classical economic theory would predict.
  • CRISPR could be used to create new crops out of the wild ancestors of our current crops.

S&P green rating

Standard and Poor’s is coming out with a new rating system for the green-ness of bonds.

Our proposed Green Bond Evaluation methodology looks beyond the governance and management of a bond by providing an analysis and estimate of the environmental impact of the projects or initiatives financed by the bond’s proceeds over its lifetime relative to a local baseline. This would be in addition to assessing the governance and transparency surrounding the bond. When evaluating environmental impact, the methodology would consider both climate change mitigation and adaptation projects.

Mitigation projects focus on efforts to reduce or prevent the emission of greenhouse gases, ranging from upgrades to conventional generation projects to new renewable energy and energy efficiency initiatives. Adaptation projects aim to take practical steps toward reducing the exposure to and managing the impact of natural catastrophes, such as building the resilience of communities and critical infrastructure against an increased risk of extreme weather events due to climate change.

The output of the Green Bond Evaluation would include at least three scores (a Transparency score, a Governance score and a Mitigation score and/or Adaptation score, as relevant…

An interesting question is whether the idea is that investors would expect to make more on a green investment, or whether some investors would be willing to settle for less in exchange for the satisfaction of having a positive impact. Borrowers would have a financial incentive to be good if doing so meant a lower interest rate, which kind of supports the latter possibility. Exactly why the rating agency itself is motivated to do this was unclear to me. But after digging into the paper a little, it looks like governments and companies will have an incentive to show that they are complying with the Paris agreement, so that may be part of what is driving this.

climate change starting to bite in Alaska

Bloomberg has an article about the effects of climate change in Alaska, and failure to deal with them. Surprisingly, it sounds like the state was making some limited strides under Sarah Palin but has completely dropped the ball since.

Across Alaska, in towns built on permafrost, rising temperatures are causing the ground to sink, damaging buildings and roads. In towns built on the coast, less sea ice means greater exposure to storms and floods. Drier conditions have led to more forest fires. Extreme weather killed or injured as many Alaskans in 2015 as in the previous 10 years combined. “Environmental change is not a theoretical in Alaska,” says Rick Thoman, the state’s climate sciences and services manager for the National Weather Service. “It’s happening, and it’s accelerating.”

Alaska was once at the vanguard of states trying to deal with global warming. In 2007, then-Governor Sarah Palin established a climate change subcabinet to study the effects of warmer weather and find policies to cope with them. Over three years, the legislature provided about $26 million in funding. But Palin’s successor, Republican Sean Parnell, disbanded the group in 2011. That year, Alaska withdrew from a federal program that provides funds for coastal management because of concern the program might restrict offshore oil extraction. Since then, lower oil prices, combined with dwindling production, have left the state with a budget crisis that’s among the worst in the U.S. Just when climate change is having real impact, Alaska has less and less capacity to deal with it…

Alaska is an extreme example of a national failure to prepare for climate change. Across the U.S., state funding for environmental projects, such as beach erosion control or upgraded sewage systems, peaked in 2007, even as capital expenditures have since risen 25 percent. States along the Atlantic and Gulf coasts have resisted adopting the latest model building codes designed to protect residents against storms and other extreme weather.

Along with its failure to deal with climate change, it sounds like Alaska has squandered its oil wealth. It could have converted its natural capital in financial capital that future generations could use to deal with the consequences of extracting those natural resources – pretty much a textbook definition of sustainability. It’s not the only failure at the state level – my home state of Pennsylvania could have used royalties from the shale boom to reduce its enormous state and municipal pension mess, but it didn’t and it’s mostly too late now.

 

small modular reactors

Even though there haven’t been a lot of commercial nuclear reactors built in the U.S., nuclear energy research and development has progressed since the plants we are most familiar with from the 1970s. Here is Forbes talking about a new type of small modular reactor.

This nuclear reactor is something that we’ve never seen before – a small modular reactor that is economic, factory built and shippable, flexible enough to desalinate seawater, refine oil, load-follow wind, produce hydrogen, modular to make the power plant any size, and that provides something we’ve all been waiting for – a reactor that cannot meltdown.

This last point is the really big deal with SMRs. The small size of each module changes the surface-area-to-volume ratio such that heat can be siphoned off easily so that the reactor can’t melt down…

Refueling of SMRs do not require the nuclear plant to shut down. The small size and large surface area-to-volume ratio of NuScale’s reactor core, that sits below ground in a super seismic-resistant heat sink, allows natural processes to cool it indefinitely in the case of complete power blackout, with no humans needed to intervene, no AC or DC power, no pumps, and no additional water for cooling.

I support nuclear energy provided the risks of past designs can be mitigated, and it sounds like there is progress in that direction. Uranium still has to be mined, enriched, transported, and disposed of safely, of course, and safer reactors do not address that issue. There is also the proliferation issue, coupled with the fairness issue of who gets to decide which countries are allowed to have nuclear technology and which are not. But there are no zero-risk options. With the health and climate risks of continuing to burn fossil fuels on a massive scale becoming more obvious every day, we should be giving nuclear a cautious look.

palm oil and peat

Mongabay explains why draining peatlands to grow oil palms is not a great idea.

Peat is a type of soil composed of partially decayed organic material such as vegetation that accumulates over time in a water-saturated environment lacking in oxygen. Peatlands are characterized by a thick layer of peat, often several meters deep that can take thousands of years to form.

Peat swamp forests act as massive carbon sinks, and when they are drained, carbon that has been slowly captured over the centuries it takes the peat to form is suddenly released into the atmosphere. A group of scientists recently uncovered the world’s largest tropical peatland in the Congo basin, thought to store the equivalent of three years’ worth of the world’s total fossil fuel emissions. The draining of peatlands can also lead to widespread subsidence, or sinking, as the organic matter rapidly decompresses and decomposes, ultimately rendering land unsuitable for agricultural or community development, according to NGO Wetlands International.

Across Southeast Asia, peat swamp forests have been cleared, drained, and burned away, often replaced by monocrop plantations or construction projects. Malaysia and Indonesia’s vast peatlands have been significantly reduced by large-scale draining and drying, leading to huge forest and peat fires across the region – such as the 2015 haze crisis that scientists say may have led to the premature deaths of 100,000 people. The event subsequently led Indonesia’s President Joko Widodo to ban the clearance and conversion of peat swamps.

 

The Death of Expertise

This sounded familiar to me:

a surge in narcissistic and misguided intellectual egalitarianism that has crippled informed debates on any number of issues. Today, everyone knows everything: with only a quick trip through WebMD or Wikipedia, average citizens believe themselves to be on an equal intellectual footing with doctors and diplomats. All voices, even the most ridiculous, demand to be taken with equal seriousness, and any claim to the contrary is dismissed as undemocratic elitism.

It’s from the Amazon description of a new book called The Death of Expertise: The Campaign Against Established Knowledge and Why it Matters.

fluoride and neurotoxicity

A coalition of groups including the American Academy of Environmental Medicine and the International Academy of Oral Medicine and Toxicology is petitioning the EPA to ban the practice of water fluoridation.

EPA should exercise its authority under TSCA to prohibit fluoridation additives because application of the Agency’s own Guidelines for Neurotoxicity Risk Assessment to the existing database on fluoride shows that (1) neurotoxicity is a hazard of fluoride exposure, and (2) the reference dose that would reasonably protect against this hazard is incompatible with the doses now ingested by millions of Americans in fluoridated areas. In fact, the amount of fluoride now regularly consumed by many people in fluoridated areas exceeds the doses repeatedly linked to IQ loss and other neurotoxic effects; with certain subpopulations standing at elevated risk of harm, including infants, young children, elderly populations, and those with dietary deficiencies, renal impairment, and/or genetic predispositions.

The risk to the brain posed by fluoridation additives is an unreasonable risk because, inter alia, it is now understood that fluoride’s predominant effect on tooth decay comes from topical contact with teeth, not ingestion. Since there is little benefit in swallowing fluoride, there is little justification in exposing the public to any risk of fluoride neurotoxicity, particularly via a source as essential to human sustenance as the public drinking water and the many processed foods and beverages made therefrom. The addition of fluoridation chemicals to water thus represents the very type of unreasonable risk that EPA is duly authorized to prohibit pursuant to its powers and responsibilities under Section 6 of TSCA, and Petitioners urge the Agency to exercise its authority to do so.

I admit I hadn’t heard of these particular groups, but at first glance they appear to be reputable. I might have previously lumped the anti-fluoride movement in with the anti-vaccine movement or the anti-global warming movement, as pseudo-scientific mumbo jumbo at best and a serious danger to the public at worse. But unlike vaccines, the health benefits of fluoridation might not be all that great. If something is not useful and we are not sure if it is toxic or not, there is a strong argument for erring on the side of caution. Maybe one day we’ll look back at water fluoridation similarly to how we look at leaded gasoline or mercury thermometers today – “what were we thinking?”

sea level rise and high tide flooding

From PLOS One:

Sea level rise drives increased tidal flooding frequency at tide gauges along the U.S. East and Gulf Coasts: Projections for 2030 and 2045

Tidal flooding is among the most tangible present-day effects of global sea level rise. Here, we utilize a set of NOAA tide gauges along the U.S. East and Gulf Coasts to evaluate the potential impact of future sea level rise on the frequency and severity of tidal flooding. Using the 2001–2015 time period as a baseline, we first determine how often tidal flooding currently occurs. Using localized sea level rise projections based on the Intermediate-Low, Intermediate-High, and Highest projections from the U.S. National Climate Assessment, we then determine the frequency and extent of such flooding at these locations for two near-term time horizons: 2030 and 2045. We show that increases in tidal flooding will be substantial and nearly universal at the 52 locations included in our analysis. Long before areas are permanently inundated, the steady creep of sea level rise will force many communities to grapple with chronic high tide flooding in the next 15 to 30 years.

The Convergence

from Amazon:

Convergence is a history of modern science with an original and significant twist. Various scientific disciplines, despite their very different beginnings, and disparate areas of interest have been coming together over the past 150 years, converging and coalescing, to identify one extraordinary master narrative, one overwhelming interlocking coherent story: the history of the universe. Intimate connections between physics and chemistry have been revealed as have the links between quantum chemistry and molecular biology. Astronomy has been augmented by particle physics, psychology has been increasingly aligned with physics, with chemistry and even with economics. Genetics has been harmonised with linguistics, botany with archaeology, climatology with myth. This is a simple insight but one with profound consequences. Convergence is, as Nobel Prize-winning physicist Steven Weinberg has put it, ‘The deepest thing about the universe.’ This book does not, however, tell the story by beginning at the beginning and ending at the end. It is much more revealing, more convincing, and altogether more thrilling to tell the story as it emerged, as it began to fall into place, piece by piece, converging tentatively at first, but then with increasing speed, vigour and confidence. The overlaps and interdependence of the sciences, the emerging order that they are gradually uncovering, is without question the most enthralling aspect of twenty-first-century science.
