Summary:  About as expected.


With more and more vaccinations, there will continue to be a decline of COVID-19, and the pandemic will end.  The virus will stick around for a very long time, but a kind of herd immunity will prevail, preventing serious outbreaks.

The Science Agenda from Scientific American this month dealt with postpandemic health habits.  We can expect some social adjustments:

  • Some variation of the Oriental way of greeting each other will become commonplace.  Handshakes and cheek-kissing will decline.
  • Masks will not go away. 
    • Those who have a respiratory illness will more and more stay at home or wear a mask so as to avoid spreading the ailment.
    • Governments will need to expand sick leave so that employees can afford to remain isolated.
    • The "hero" image of sick people going to work will shift to becoming a "villain."
    • The problem of children being sent to school with just a cold will become a debatable controversy.  Mask wearing might be a reasonable compromise.
  • While quarantining and social distancing to complement mask-wearing were why, few caught the flu and as many colds during the past year and a third:
    • There were 24,000 flu deaths in the U.S. in 2019.
      • ONLY 450 flu deaths this season.
      • A good number of comparison is the 38,000 traffic deaths/year in the U.S.  If only there can be a solution to this problem.
    • All of 2020 to the present, I have not suffered from any cold or the flu.  I suspect most of you reading this must too have been as fortunate.

From the New York Times this morning (sorry about cutting-off the right side.  Should you wish to see the entire bullet entries, click on my parallel blog.)

  • More globally, another story in the magazine, by Aurora Almendral, focuses on decreasing the shipping trade’s carbon footprint. Cargo vessels are among the largest machines on the planet, and shipping generates 2.9 percent of global carbon-dioxide emissions — nearly as much as the entirety of South America. Some experts believe using wind through modern sails could considerably reduce that number.  (That ship above is Oceanbird from Sweden, to become the largest wind-powered ship, with a purpose to transport 7,000 cars and trucks across oceans.)
  • “You might wake in the morning on a mattress made from recycled CO2,” Jon Gertner writes. “You might drive your car — with parts made from smokestack CO2 — over roads made from CO2-cured concrete. And at day’s end, you might sip carbontech vodka while making dinner with food grown in a greenhouse enriched by recycled CO2.”

  • Other companies are developing more environmentally friendly manufacturing techniques that would repurpose carbon dioxide into building materials, fuels, plastics and even fish food.

Most geoengineering solutions to global warming develop systems to take carbon dioxide out of the air, and at high cost.  The Blue Revolution shows promise for remediating climate change and reducing the severity of hurricanes, while making an economic profit by developing consumer products:  next generation fisheries, marine biomass plantations, renewable energy, freshwater, marine biopharmaceuticals and the like.

Saul Griffith began to gain credibility after a TED talk in 2007.  Also from the NYT this morning:


In Australia, Griffith said, a kilowatt-hour of energy generated by rooftop solar panels costs about a third of what it would from a U.S. power grid. “We can make everyone’s energy future cheaper, but politics has to work with technology, which has to work with finance,” he said.

I've been harping on this point for decades.  Government incentives and regulations remain attractive for conventional energy forms like fossil fuels and nuclear.  Here is Everything You Need to Know About Fossil Fuel Subsidies.   And How Biden Can Put the U.S. on a Path to Carbon-Free Electricity.


Finally, from the NYT:

While the lenient sentence gives an impression that everyone will thus get off with almost no penalty, read this article which suggests that will not be the case.  The Buffet resignation on the surface appears to merely be a formality about how old he is getting, but I suspect there is a lot more that will someday surface.
