Human domination of the biosphere: Rapid discharge of the earth-space battery foretells the future of humankind

Human domination of the biosphere: Rapid discharge of the earth-space battery foretells the future of humankind | Sustain Our Earth | Scoop.it

Earth is a chemical battery where, over evolutionary time with a trickle-charge of photosynthesis using solar energy, billions of tons of living biomass were stored in forests and other ecosystems and in vast reserves of fossil fuels. In just the last few hundred years, humans extracted exploitable energy from these living and fossilized biomass fuels to build the modern industrial-technological-informational economy, to grow our population to more than 7 billion, and to transform the biogeochemical cycles and biodiversity of the earth. This rapid discharge of the earth’s store of organic energy fuels the human domination of the biosphere, including conversion of natural habitats to agricultural fields and the resulting loss of native species, emission of carbon dioxide and the resulting climate and sea level change, and use of supplemental nuclear, hydro, wind, and solar energy sources. The laws of thermodynamics governing the trickle-charge and rapid discharge of the earth’s battery are universal and absolute; the earth is only temporarily poised a quantifiable distance from the thermodynamic equilibrium of outer space. Although this distance from equilibrium is comprised of all energy types, most critical for humans is the store of living biomass. With the rapid depletion of this chemical energy, the earth is shifting back toward the inhospitable equilibrium of outer space with fundamental ramifications for the biosphere and humanity. Because there is no substitute or replacement energy for living biomass, the remaining distance from equilibrium that will be required to support human life is unknown.

Washington State University researchers say environmental factors are having an underappreciated effect on the course of disease and evolution by prompting genetic mutations through epigenetics, a process by which genes are turned on and off independent of an organism's DNA sequence.

Glaciers melt faster than ever | Sustain Our Earth | Scoop.it
The World Glacier Monitoring Service, domiciled at the University of Zurich, has compiled worldwide data on glacier changes for more than 120 years. Together with its National Correspondents in more than 30 countries, the international service just published a new comprehensive analysis of global glacier changes in the Journal of Glaciology. In this study, observations of the first decade of the 21st century (2001-2010) were compared to all available earlier data from in-situ, air-borne, and satellite-borne observations as well as to reconstructions from pictorial and written sources.

Risque climatique : les investisseurs pourraient perdre 4 200 milliards de dollars

Risque climatique : les investisseurs pourraient perdre 4 200 milliards de dollars | Sustain Our Earth | Scoop.it

C’est une nouvelle alerte pour les investisseurs ayant des actifs dans les compagnies extractives d’énergies fossiles. Cette fois, elle est lancée par The Economist Intelligence Unit, qui vient de publier une étude sur le risque carbone. Les pertes liées au changement climatique seraient colossales, atteignant dans le meilleur des cas 4 200 milliards de dollars. Et dans le pire, jusqu’à ... 57 000 milliards de dollars.

SustainOurEarth's insight:

4 200 milliards de dollars. C’est le PIB du Japon, la troisième économie mondiale. C’est aussi la somme que les investisseurs privés pourraient voir partir en fumée d’ici la fin du siècle à cause du réchauffement climatique. Et ce même si ce réchauffement global est limité à 2 degrés, prévient The Economic Intelligence Unit, qui a publié, avec l'assureur britannique Aviva, une étude sur le coût de l’inaction le 24 juillet dernier.

"Les investisseurs sont actuellement confrontés à un choix difficile", explique Brian Gardner, l’auteur du rapport."Soit ils vont voir leurs participations dans des entreprises productrices de combustibles fossiles se déprécier à cause de mesures réglementaires plus strictes, soit ils vont faire face à des pertes substantielles dans leurs portefeuilles à cause du changement climatique. Entre ces deux voies, il y en a une troisième, qui consisterait pour les investisseurs de long terme à transférer leurs investissements vers une économie bas carbone, plus viable."

Minimum Wage or Living Income? | Sustain Our Earth | Scoop.it

As robots increasingly replace human labor, humans will need incomes to replace wages from work. That is why the idea of an unconditional basic income, long advocated by free-market and socialist thinkers alike, is a measure whose time has come.

Wildfire threat spreads across warming world | Tim Radford | Climate News Network

Wildfire threat spreads across warming world | Tim Radford | Climate News Network | Sustain Our Earth | Scoop.it

Wildfire – nature’s way of turning fallen vegetation into the next season’s nutrients – is a growing hazard. In the last 35 years, the wildfire season has grown longer by a fifth, and wildfire is now a threat to one fourth of all the plant-covered land on the planet.

US researchers report in Nature Communications that since 1970 the number of days without rain has increased by well over one day every decade.

William Jolly of the US Forest Service in Missoula, Montana and colleagues say they examined the fire season worldwide for the study period, taking into consideration all the factors that are used to calculate fire hazard: wind, humidity and temperature, as well as rainfall levels.

They found that the combined changes in the surface weather have meant that the fire season has increased so far by 18.7%

Worldwide, wildfires sear, scorch or incinerate about 350 million hectares of ground cover every year. Changes in the rainfall patterns were a factor, with the number of rain-free days increasing by 1.31 days per decade. The season of smoke and cinders and smouldering stumps had been extended almost everywhere.

CO2 removal cannot save the oceans—if we pursue business as usual

CO2 removal cannot save the oceans—if we pursue business as usual | Sustain Our Earth | Scoop.it
Greenhouse-gas emissions from human activities do not only cause rapid warming of the seas, but also ocean acidification at an unprecedented rate. Artificial carbon dioxide removal (CDR) from the atmosphere has been proposed to reduce both risks to marine life. A new study based on computer calculations now shows that this strategy would not work if applied too late. CDR cannot compensate for soaring business-as-usual emissions throughout the century and beyond, even if the atmospheric carbon dioxide (CO2) concentration would be restored to pre-industrial levels at some point in the future. This is due to the tremendous inertia of the ocean system. Thus, CDR cannot substitute timely emissions reductions, yet may play a role as a supporting actor in the climate drama.

SustainOurEarth's insight:

"Last month, during a trip to Europe, I mentioned that I plan to invest $1 billion in clean energy technology over the next five years. This will be a fairly big increase over the investments I am already making, and I am doing it because I believe that the next half-decade will bring many breakthroughs that will help solve climate change. As I argued in this 2010 TED talk, we need to be able to power all sectors of the economy with sources that do not emit any carbon dioxide. But when it comes to preventing the worst effects of climate change, the investments I make will matter much less than the choices that governments make. In Europe I got to talk about these choices with several political leaders, and in this post I want to share the steps that I encouraged them to take."

Capturer du CO2 est inefficace contre l'acidification des océans

Déployer massivement des techniques de capture du CO2 de l'atmosphère ne permettra pas d'enrayer l'acidification des océans, un phénomène qui menace de nombreuses espèces marines et qui va perdurer pendant des siècles, indique une étude publiée lundi.

Retirer chaque année de l'atmosphère, et jusqu'en 2700, l'équivalent de la moitié des émissions actuelles - un niveau très ambitieux - ne permettrait pas de retrouver les conditions d'acidité des océans de l'ère pré-industrielle, indiquent les auteurs des travaux parus dans Nature climate change.
