LifeItself

The Arctic is burning across Alaska, Greenland and Siberia. The satellite image below shows smoke enveloping millions of square kilometers in Russia. You are witnessing a giant positive feedback to global warming. All hell is breaking loose, while most Americans are either asleep or in active denial. Four more years of Trump, and this hell will be decades closer to your bedrooms, my dear fellow Americans. Wildfires are burning across 11 regions of Russia amid a hot, dry summer. Even regions free from fire are feeling its effects, as air masses have spread the smoke plumes across a wide area. (Four million square kilometers as of July 28, 2019.) The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite acquired this natural-color image on July 21, 2019. Source: NASA Earth Observatory , accessed 28 July, 2019. Let me be clear.  The future is in solar energy, as in solar PV modules, passive solar heaters and wind turbines. The sun will last a lot longer t...

Recently, I gave in Polish an opening lecture, “Can we salvage our global civilization?”, at a one-day conference of the Polish Academy of Arts and Sciences (PAU). The conference took place in the Isabela Lanckoronska Auditorium at the historic PAU building on Slawkowska 17 Street in Kraków. This conference, “Civic organizations and local communities faced with climate change disasters,” was organized by the Committee on Threats to Civilization of PAU. The last lecture was given by a young activist from a well-known non-profit, who manifestly misled the audience with his proposed implementation of the Green New Deal that would immediately shut down all coal-fired electric power plants in Poland, and replace them with wind turbines, PV arrays and geothermal wells. I pointed out to the nice young man that his radical solution would cause immediate power blackouts in Poland, and asked if he shouldn't have mentioned some of the problems with the transition? His answer was that the or...

In Part I, I showed how most people have little understanding of the complex issues of global power transition from fossil fuels to renewables, and may jump to false and dangerous conclusions colored green by ignorance.  In Part II, I demonstrated that if humans continue to outdo rabbits in procreation, no energy transition  strategy will ever succeed and the entire planet will become a miserable, Mordor-like dump with most nature extinct. Here I will sketch the gargantuan scale of nonrenewable resources necessary to make the "Green New Deal" plausible.  Some of these resources are already depleted or miners cannot produce them fast enough to keep you happy.  Thus, you will not be pleased with what you read, but I am not alone . And by the depleted resources I mean not only the rich ores, easy oil and natural gas, but also the tropical and boreal forests, tundra, the Midwestern soil disappearing fast into the Gulf of Mexico in exchange for the "renewable" ...

In Part I of this blog, I explained  difficulties with comprehending the astronomical scale of change that is awaiting us, the rich people in the developed countries, in our journey to a more sustainable, greener future of humankind.  I have also pointed out a few of the many ways people escape responsibility for the crimes against the Earth we  - you and I - have committed.  And, please, let's not blame the poor people in Honduras or Gabon for our sins, plastic in the oceans and greenhouse gas emissions. Exponential growth.   Remember a lonely lily pad floating on an empty pond?  She multiplied daily, so after day one, there were two lilies; after two days, four lilies; then eight; and so on.  After 20 days, there were 1,048,576 lilies. After 21 days, there were  2,097,152 lilies that covered the pond, exhausted nutrients and died.  Question:  After which day was the pond half-filled?  You already know the answer, it was...

Jeff Bezos, Elon Musk and others have been touting the multitudinous advantages of colonizing the Moon and Mars. The scientific idiocies of these proclamations are so outlandish that I will not bother commenting on them. But, at the same time, Stephen Hawking's name has come up in the context of Mars colonization. Dr. Nate Hagens uses Hawking's ideas about Mars colonization in his Reality 101 course at the University of Minnesota to illustrate the point that human society is composed of tiny islands of high competence floating in a vast sea of narratives. Let me start from quoting a recent email by JDW on the subject of human escape to outer space: "Without a synthesis which shows how different narratives relate to one another, people are free to use “verbal logic” to create properly-constructed sentences which don’t correspond to possible realities. “Verbal logic” is nearly an oxymoron, because there’s not much in the way of error-correction built into it. Anyth...
