I could start from telling you about my own impressions of human delusions, but I could not possibly introduce the subject better than the ENCYCLICAL LETTER, LAUDATO SI’ OF THE HOLY FATHER FRANCIS ON CARE FOR OUR COMMON HOME.  Here is a short fragment of the Preamble pertinent to what I want to say later: 1. “LAUDATO SI’, mi’ Signore” – “Praise be to you, my Lord”. In the words of this beautiful canticle, Saint Francis of Assisi reminds us that our common home is like a sister with whom we share our life and a beautiful mother who opens her arms to embrace us. “Praise be to you, my Lord, through our Sister, Mother Earth, who sustains and governs us, and who produces various fruit with colored flowers and herbs.” 2. This sister now cries out to us because of the harm we have inflicted on her by our irresponsible use and abuse of the goods with which God has endowed her. We have come to see ourselves as her lords and masters, entitled to plunder her at will. The violen...

The proper mass balance of carbon fluxes in terrestrial ecosystems, described in Appendix B of my OECD paper (2007), confirms the compelling thermodynamic argument that sustainability of any ecosystem requires all mass to be conserved on the average. The larger the spatial scale of an ecosystem and the longer the time-averaging scale are, the stricter adherence to this rule must be. Such are the laws of nature. Physics, chemistry and biology say clearly that there can be no sustained net mass removal from any large ecosystem for more than a few decades. A young forest in a temperate climate, shown in the previous blog , grows fast in a clear-cut area and transfers nutrients from soil to the young trees. The young trees grow very fast (there is a positive net primary productivity or NPP ), but the amount of mass accumulated in the forest is small. When a tree burns or dies some or most of its nutrients go back to the soil. When this tree is logged and hauled away, almost no nutr...

In the last bog , I told you how the law of mass conservation governs the large-scale behavior of Earth's households - ecosystems - that must recycle all mass on average and export only low quality heat into the cold universe.  Now, I will give you a few useful definitions of cyclic processes, sustainability, and ecosystem productivity. Let me start from stating the obvious:  We live in a spaceship we cannot leave, a gorgeous blue, white and green planet Earth that takes us for a spin around her star, the Sun, each year. But this statement is imprecise. We really live on a vanishingly thin skin of the Earth, her ecosphere .   Think of this skin as of a thin delicate membrane, teaming with life and beauty, but incredibly fragile. We trample on this membrane and poison it.  Then we act surprised when it brakes and shrivels. Practically all life on the Earth exists between two concentric spheres defined by the mean Earth surface at the radial distance ...

In this blog and other blogs that will follow, I will show you how laws of nature limit human expectations borne from ignorance and arrogance.  First, I would like to remind those readers who might be scientifically-challenged that the laws of physics, chemistry, and biology are called "laws," because we, scientists, have found no exceptions to them in as many experiments as have been carried out for as long as these laws have been on the books.  I repeat: As opposed to legal laws, the laws of nature do not allow exceptions, do not listen to lobbyists, shrug off presidents, and dispatch ignorant scientists to the trash bin of history. Just like ignorance of the law cannot be a legal excuse, ignorance of the laws of nature is a crime, not an oops. But, because most societies do not care much about nature, this crime generally goes unpunished by human laws.  In the long run, however, trespassing against the laws of nature has only one outcome: We perish by one means or a...

...As sheep, that step from forth their fold, by one, Or pairs, or three at once; meanwhile the rest Stand fearfully, bending the eye and nose To ground, and what the foremost does, that do The others, gath'ring round her, if she stops... Dante Alighieri, Purgatorio , Canto 14 Most economists make it all too easy to bash them. When I think of how eerily detached from reality the main stream of economics is, I also recall the situation with corn ethanol in 2005.  Only two U.S. faculty, Dr. David Pimentel and I, went public against the nonsense that was being propagated throughout the society by the ill-informed greens, scientists, lobbyists, economists, venture-capitalists, lawmakers, and almost everyone in the media.  We were both savaged at the time and for a few more years.  Now everybody shrugs their arms and says pretty much what we were saying all along.  Today, Chapter 2 of the same nonsense, or the "second generation biofuels," is being closed at a g...

Dr. Daniel Yergin has just published "The Quest," "a magisterial masterpiece," according to an endorsement by Dr. Lawrence Summers, a well known economist and ex-President of Harvard University. Mr. Yergin received his B.A. from Yale University in 1968, and earned his Ph.D. in International Relations (1974) from Cambridge University. The other endorsements came from: Mr. Walter Isaacson, a writer and biographer, and President of The Aspen Institute. Dr. Henry Kissinger, who received his A.B., A.M. and Ph.D. degrees at Harvard University. His doctoral dissertation was titled "Peace, Legitimacy, and the Equilibrium (A Study of the Statesmanship of Castlereagh and Metternich)." Mr. Steve Coll, a journalist and writer, and President of the New America Foundation. Mr. Fred Krupp, an environmental lawyer from the University of Michigan, and CEO of the Environmental Defense Fund. Mr. Frederick W. Smith, B.A. in economics from Yale University, CEO of FedEx...

Our society, like a novel lunatic, needs bad ideas, so that our collective craziness can have shape and direction.  Biofuels are one of such brazenly bad ideas that have crystallized a bunch of lunatic government policies and attracted other, completely unrelated lunatics. All these lunatics became friends of biofuels. "Ideas on Earth," observed Kilgore Trout, "were badges of friendship or enmity.  Their content did not matter.  Friends agreed with friends, in order to express friendliness.  Enemies disagreed with enemies, in order to express enmity."  And so it goes. Unfortunately, there were more bad news for the imaginary "advanced biofuels."  These no doubt miraculous, but yet undiscovered substances seem to fall into the domain of dot-con ventures sponsored by the fabulously well-to-do ventriloquists.  [Ventriloquy, is an act of stagecraft in which a person (a ventriloquist) manipulates his or her voice so that it appears that the voice is...
