Da li odbijaš da čuvaš životnu sredinu samo zato što će neko profitirati od toga? Ili ne veruješ da je životna sredina uopšte ugrožena?

Ni jedno ni drugo. prosto će lagati da su je opravili i da nije više ugrožena. Kao što sada lažu da je genocid na prs u dupe.

Milton Fridman iz 1951. Javno mnjenje dovodi do promjene zakonodstva u etapama od 20 godina. Ako hoćete nešto da promijenite 2038. godine, počnite sada. E tako neoliberali oće nešto da muljaju s klimom pa su počeli s Alom Gorom da muljaju prije petnaestak godina. Taman prije genocida.

Konačno neko ko iznosi nekakve kontra-argumente, da ugljendioksid nije toliko bitan, i čak ni loš u velikim količinama u atmosferi. Slabi su ti kontra-argumenti, ali treba ceniti trud. Autor je jedan od onih hrišćana koji veruju da je Bog Zemlju napravio savršenom, i da nema te ljudske sile koja bi mogla da pokvari zemaljske ekosisteme.

Pace of Bering Sea changes startles scientists 
 
Quote

In February, southwest winds brought warm air and turned thin sea ice into "snow cone ice" that melted or blew off. When a storm pounded Norton Sound, water on Feb. 12 surged up the Yukon River and into Kotlik, flooding low-lying homes. Lifelong resident Philomena Keyes, 37, awoke to knee-deep water outside her house.
"This is the first I experienced in my life, a flood that happened in the winter, in February," Keyes said in a phone interview.
 
 
(...)
 
 
The Bering Sea last winter saw record-low sea ice. Climate models predicted less ice, but not this soon, said Seth Danielson, a physical oceanographer at the University of Alaska Fairbanks.
"The projections were saying we would've hit situations similar to what we saw last year, but not for another 40 or 50 years," Danielson said.

Starbucks Promised a Recyclable Drink Lid. Don’t Believe the Hype.
 
Quote
The lids are made from polypropylene, only 5.1 percent of which was recycled in the U.S. in 2015, according to the most recent data from the Environmental Protection Agency. (Just over 9 percent of all plastics were recycled.) And that was before China, which had been processing most U.S. plastic waste, including polypropylene, stopped accepting the vast majority of such waste in January 2018.

Zna se već za to. Zato je Tesla i počeo da razvija powerwall i powerpack baterije da bi ubrzao prelazak na solarnu energiju, jer tek kad imaš bateriju solarna energija dolazi do izražaja. Cilj je da se smanji cena solarne tehnologije toliko da može da zameni naftu i ugalj skoro svuda.

Dva zanimljiva teksta. Jedan stariji, koji argumentuje da se globalno mora promeniti način ljudske ishrane kako bi se predupredile klimatske promene (nagađate, kroz redukciju konzumacije mesa):


Huge reduction in meat-eating ‘essential’ to avoid climate breakdown

I drugi, noviji, koji podseća da prebacivanje odgovornosti za predupređenje katastrofe na individue ne donosi korist:


You can't save the climate by going vegan. Corporate polluters must be held accountable.

Da presečemo s nečim svežim 'n' senzacionalističkim. U prilog tezi da smaranje ljudi oko korišćenja palstičnih slamki za pijenje soka najviše doprinosi da se zaboravi koje STVARNO, efektivno odgovoran za najveći deo zagađenja (a koje je i u vezi sa, jelte, promenom klime), spiska 100 menadžera kompanija koje su odgovorne za 70% svih emisija gasove koji proizvode efekat staklene bašte. Naravno "100 ljudi je krivo za svu našu nesreću" jeste namerno pojednostavljenje radi dojma itd. ali ovo je svejedno zgodno imati na umu kad pomislimo da bi to što smo danas poneli zembil u samoposlugu umesto da uzmemo kesu znatno uticalo na situaciju kada bi samo i naše komšije radile isto:

It turns out planes are even worse for the climate than we thought
 
Nisu kemtrejls, nego kontrejls, jelte, ali evo šta studija kaže:
 
Quote
The contrails left by aeroplanes last only hours. But they are now so widespread that their warming effect is greater than that of all the carbon dioxide emitted by aeroplanes that has accumulated in the atmosphere since the first flight of the Wright brothers.
 
(...)
 
Altogether, flying is responsible for around 5 per cent of global warming, the team says, so this figure will soar even higher – and no meaningful actions are being taken to prevent this.

We’ve already built too many power plants and cars to prevent 1.5 ˚C of warming

Quote
In a sequel to that paper published in Nature today, researchers found we’re now likely to sail well past 1.5 ˚C of warming, the aspirational limit set by the Paris climate accords, even if we don’t build a single additional power plant, factory, vehicle, or home appliance. Moreover, if these components of the existing energy system operate for as long as they have historically, and we build all the new power facilities already planned, they’ll emit about two thirds of the carbon dioxide necessary to crank up global temperatures by 2 ˚C.
If fractions of a degree don’t sound that dramatic, consider that 1.5 ˚C of warming could already be enough to expose 14% of the global population to bouts of severe heat, melt nearly 2 million square miles (5 million square kilometers) of Arctic permafrost, and destroy more than 70% of the world’s coral reefs. The hop from there to 2 ˚C may subject nearly three times as many people to heat waves, thaw nearly 40% more permafrost, and all but wipe out coral reefs, among other devastating effects, research finds.

Learning from mistakes in climate research

Quote
Among papers stating a position on anthropogenic global warming (AGW), 97 % endorse AGW. What is happening with the 2 % of papers that reject AGW? We examine a selection of papers rejecting AGW. An analytical tool has been developed to replicate and test the results and methods used in these studies; our replication reveals a number of methodological flaws, and a pattern of common mistakes emerges that is not visible when looking at single isolated cases. Thus, real-life scientific disputes in some cases can be resolved, and we can learn from mistakes. A common denominator seems to be missing contextual information or ignoring information that does not fit the conclusions, be it other relevant work or related geophysical data. In many cases, shortcomings are due to insufficient model evaluation, leading to results that are not universally valid but rather are an artifact of a particular experimental setup. Other typical weaknesses include false dichotomies, inappropriate statistical methods, or basing conclusions on misconceived or incomplete physics. We also argue that science is never settled and that both mainstream and contrarian papers must be subject to sustained scrutiny. The merit of replication is highlighted and we discuss how the quality of the scientific literature may benefit from replication.

June was the warmest June ever recorded, but there's a bigger problem 
 
Quote

"At this point, the inexorable increase in global temperatures is entirely predictable," said Sarah Green, an environmental chemist at Michigan Technological University. She noted that NASA's updated data is added proof that climate models have accurately predicted Earth's continued warming as heat-trapping gasses amass in the atmosphere.
"As we have shown in recent work, the record warm streaks we’ve seen in recent years simply cannot be explained without accounting for the profound impact we are having on the planet through the burning of fossil fuels and the resulting increase in atmospheric greenhouse gas concentrations," added climate scientist Michael Mann, the director of the Earth System Science Center at Penn State University.

All the News Is BadFrancis Gooding 
  • BuyThe Uninhabitable Earth: A Story of the Future by David Wallace-Wells
     Allen Lane, 320 pp, £20.00, February, ISBN 978 0 241 35521 3

 How long do we have left, and how bad will it get? David Wallace-Wells opens his book with a short, sharp reality check: ‘It’s worse, much worse, than you think.’ All the news is bad. Marshalling research from across the sprawling field of climate studies, Wallace-Wells paints a picture of disastrous change on an almost incomprehensible scale. Transformations that will have consequences for thousands of years to come are already being expressed in sudden crises that spring up overnight. The changes are at once planetary and minute, affecting everything from the earth’s variable ability to reflect light from the sun to the microbes inside your body. Everything, it seems, is dissolving.
  The book’s focus is on the most direct effects of global warming – hotter temperatures, rising seas, extreme weather and so on – as well as what these effects mean for humanity. Wallace-Wells leaves out much of our disastrous impact on the natural world. He doesn’t dwell on biodiversity loss, for instance, or the details of the mass extinction that we are by all accounts now living through, though he reminds us that of the five previous mass extinctions, only the most recent was caused by an asteroid. What was responsible for the other four? ‘Climate change produced by greenhouse gas.’ The deadliest occurred 250 million years ago, at the end of the Permian period, when 96 per cent of life on earth was wiped out. High levels of carbon dioxide in the atmosphere led to around 5°C of warming, which in turn triggered the release of methane – a much more powerful greenhouse gas – and possibly highly toxic and ozone-destroying hydrogen sulphide, produced by the anaerobic green sulphur bacteria that began to thrive in the warm oceans. We are currently adding carbon to the atmosphere at a rate ‘considerably faster’ than it took to cause this near-total erasure of complex life. ‘By most estimates,’ Wallace-Wells writes, ‘at least ten times faster.’ We may not be at anything like end-Permian levels yet, but the parallels are clear. The Intergovernmental Panel on Climate Change (IPCC) predicts that if emissions continue to rise at the current rate, the earth could experience as much as 4.5°C of warming by 2100. Permafrost in the Arctic is already melting, with the potential to release large quantities of methane, while the hydrogen sulphide that is thought to have ‘capped the end-Permian extinction, once all the feedback loops had been triggered’, is currently ‘bubbling out of the sea’ along a thousand-mile stretch of the Namibian coast, where green sulphur bacteria have caused a vast oceanic dead zone, devoid of oxygen and life.
It’s by no means the only one. There are now more than four hundred such dead zones in the world’s oceans, totalling an area the size of Europe. Most cluster around cities and river mouths, where the combination of warming waters, sewage pollution and fertiliser run-off causes blooms of algae whose decay leaches oxygen from the water. Others are caused by upwellings of the green sulphur bacteria, which has survived from a primordial planetary era before oxygen, waiting in the deep ocean for a chance to turn the seas back into a toxic microbial stew. Warmer seas and the subsequent changes to ocean currents mean their chance may be coming. The Baltic Sea now contains a layer of anoxic water all year round; the Gulf of Mexico dead zone is nine thousand square miles in size; it’s possible that the recently discovered dead zone in the Arabian Sea is large enough to consume the entire Gulf of Oman. Dead zones are examined briefly by Wallace-Wells in a chapter called ‘Dying Oceans’; only briefly, because he also has to consider ocean acidification, ocean warming, coral bleaching and the attendant die-offs of ocean life, as well as the slowing and potential failure of the Gulf Stream and other currents whose movements are intimately tied to regional climate. Should this last come to pass, the results would be ‘inconceivably catastrophic’. The Gulf Stream has already slowed by 15 per cent, something which hasn’t happened for at least a thousand years. A paper from 2018 suggests that the vast ocean circulation current is moving at its slowest rate for 1500 years. According to most global warming scenarios, this wasn’t supposed to happen for another hundred years.
‘Dying Oceans’ is one of 12 chapters discussing what Wallace-Wells calls the ‘elements of chaos’. Each is dedicated to a particular aspect of what we can expect in a warming world, from simple increases in temperature to crop failure, freshwater shortages, and violent and unpredictable weather, as well as secondary features such as greater migration and an increased incidence of wars. The US military is ‘obsessed with climate change’, Wallace-Wells writes, and the Pentagon is actively ‘planning for a new era of conflict governed by global warming’. They are not alone in thinking this way. The Chinese government is responding to the anticipated loss of military and naval bases in the rising Pacific by creating militarised artificial islands in the South China Sea, ‘a dry run, so to speak, for life as a superpower in a flooded world’. A new era of geopolitical contest looms, and it sounds like science fiction: end-time resource wars on a dying planet. The Uninhabitable Earth is an example of the class of writing the eco-philosopher Timothy Morton has described as ‘ecological information data dump’: quantities of frightening and confusing information, mostly out of date by the time of publication, ‘shaking your lapels while yelling disturbing facts’. Morton believes this approach is unhelpful, and that it is essentially a symptom of the diffuse psychological pain caused by climate change – an attempt to prepare us for what has in fact already happened. And most of what Wallace-Wells describes has already happened. The phenomena he documents in the first part of the book are not hypothetical outcomes or doomsday prophecies: they are accounts of real events.
Take wildfires. Wallace-Wells concentrates on California, which has always been susceptible to burning. In 2017, more than nine thousand separate wildfires were recorded, including five of the twenty worst ever recorded in the state. Two thousand square miles burned. A similar area was destroyed again in 2018 by six thousand fires, among them a giant network called the ‘Mendocino Complex’, which blazed across four counties between July and September. It grew to be bigger than New York, destroying almost half a million acres of land. Wildfires now burn twice as much land per year in the US as they did fifty years ago, and that figure is expected to double again by 2050 to twenty million acres per year. ‘For every additional degree of global warming, it could quadruple.’ This isn’t just an American problem, of course: in Greenland ten times more land than usual was lost to wildfires in 2017; in 2018, Swedish forests within the Arctic Circle succumbed to fires of unprecedented size. Wildfires in Greece killed more than a hundred people during the European heatwave of 2018, the sixth highest direct death toll in the last century. A hundred thousand fires burned across the Amazon during 2017.
Like everything else that happens within a responsive and interconnected ecological system, fires contribute to cumulative processes. Soot and ash from boreal fires blacken the northern ice sheets, which then absorb more solar heat and melt faster. Denuded hillsides increase the likelihood of disasters such as flooding and landslides (thousands were evacuated and many killed in the mudslides that followed the 2017 California fires). Burning forests release vast quantities of carbon into the atmosphere. One major wildfire in California can set the emission gains of the entire state back to zero for the year, making ‘a mockery of the technocratic, meliorist approach to emissions reduction’. Recent news reports suggest that Arctic wildfires have released as much carbon dioxide in the last month as Sweden does in the course of a year.
The loss of forests to fire adds to the general disaster of worldwide deforestation, a major cause of increasing carbon emissions. It is estimated that, at current rates, tropical deforestation would produce a further 1.5°C of warming, even if emissions from fossil fuels stopped tomorrow. The loss of forest resulting from Jair Bolsonaro’s policy of opening the Amazon to ‘development’ could add 13.2 gigatons of carbon to the atmosphere before 2030, the equivalent of almost a year’s worth of Chinese and American emissions. (Given what we now know about the consequences of unabated emissions, perhaps acts of such destructive magnitude should be recognised as a special kind of international crime.)
As the unprecedented disasters, terrifying statistics and nightmare scenarios continue to mount, the links between them multiply in tangled profusion. Climate scientists refer to ‘systems crises’, Wallace-Wells to ‘cascades’: tumbling sequences of events connected within a dynamic chaos of feedback loops, amplification and reinforcement. ‘Complexity is how warming articulates its brutality,’ as Wallace-Wells puts it. Most of the known feedback mechanisms look as though they will trigger even more warming. One of the key variables complicating climate forecasts is how much more carbon we will pump into the atmosphere. On that count too, the reports are dismal. Only seven of the 195 signatories to the 2016 Paris Agreement are ‘in range’ of their carbon emissions pledges. Even if every country was to keep to its target, this could still deliver more than 3°C of warming (not given to understatement, Wallace-Wells says this would ‘unleash suffering beyond anything humans have ever experienced’). The agreed ‘must-meet target’ in 2016 was 2°C, a level which will anyway almost certainly be enough to cause the collapse of the polar ice sheets, and the attainment of which is now regarded as improbable without the massive implementation of carbon capture technology, a technology that does not exist on any meaningful scale. (Nature has dismissed global warming projections based on carbon capture and storage as ‘magical thinking’.) Some estimates suggest that to keep warming below the agreed 2°C using existing technology would require ten new carbon capture plants to open every week for seventy years. There are currently 18 plants worldwide. And since the Paris Agreement, overall emissions have risen. The World Bank predicts that there will be 140 million climate refugees by 2050; the UN thinks it might be more like 200 million, or even, in the worst-case scenario, a billion. The poorest countries, which have caused least pollution, will bear the brunt of the suffering, and already do.
‘We have already exited the state of environmental conditions that allowed the human animal to evolve in the first place,’ Wallace-Wells writes, ‘in an unsure and unplanned bet on just what that animal can endure. The climate system that raised us, and raised everything we now know as human civilisation, is now, like a parent, dead.’ He is not a climate scientist, so is perhaps less circumspect than he might be: the data here is designed to scare us. ‘I am alarmed,’ he writes. Who isn’t? We know exactly where we are, despite the continuous chatter of doubt and denial. Wallace-Wells is scathing about the oil industry, whose disinformation clogs public discourse and waylays political processes: ‘A more grotesque performance of corporate evilness is hardly imaginable, and, a generation from now, oil-backed denial will likely be seen as among the most heinous conspiracies against human health and well-being as have been perpetrated in the modern world.’
How on earth are we supposed to think about all this horror? How do we plan for the future or raise children knowing what we know? The magnitude and implications of climate change short-circuit the imagination. Wallace-Wells cites the novelist Amitav Ghosh, who has suggested that we fail to put climate change into proper perspective because we don’t yet have the stories to comprehend it. Even the refrains ‘by 2100’ or ‘by 2050’ seem more like magic charms, pushing the disaster into an infinitely receding future. Faced with a planetary-scale crisis that requires urgent collective action, contemporary minds and institutions are left embarrassingly exposed: imagining the necessary change within our political cycles, even our lifespan, appears to be an impossible leap. What will real action look like, if and when it finally comes? Wallace-Wells reminds us that we have the tools to change things, and even – a rare moment of optimism – ‘to stop it all’. His remedy involves ‘a carbon tax and the political apparatus to aggressively phase out dirty energy; a new approach to agricultural practices and a shift away from beef and dairy in the global diet; and public investment in green energy and carbon capture.’ But whether the changes that are already underway could be stopped by such measures is presently moot: ‘We … haven’t yet discovered the political will, economic might and cultural flexibility to install and activate them.’ Depressingly, it could have been so much easier. If decarbonisation had started in 2000, only a 3 per cent annual emissions reduction would have been necessary to keep us below 2°C of warming. The figure now is 10 per cent per year. If we wait until 2030, it will be 30 per cent. The UN secretary general, António Guterres, believes there is only one year left in which to begin this reduction. The IPCC says that global mobilisation on the scale of the Second World War will be necessary.
Many people, especially the young, have seen enough; like Wallace-Wells, they demand that others, especially those with the power to act, start to respond too. The pepper-spraying of Extinction Rebellion protesters in Paris in June and the claim by the former head of British counterterrorism that the group represents ‘anarchism with a smile’ illustrate how climate-related action by the public is likely to be handled, even by ostensibly liberal governments. State security services and corporate interests long ago classified environmental groups as a threat; they will not be quick to recast them as the vanguard of planetary salvation. Reporting on the environment is second only to reporting from war zones in terms of the number of journalists killed, attacked or threatened. Talk of a ‘Green New Deal’ and similar policies still belongs to political factions and activist groups, when everything we know about climate change suggests it should be the global first order of business. It may be symbolically significant for the UK government to declare a ‘climate emergency’, but what is urgently needed are vast, co-ordinated programmes of decarbonisation. The old certainties no longer apply. We are on an alien planet.

Ironično je što se mi još preganjamo oko ugljendioksida koji se relativno lako može vezati vegetacijom, a za to vreme se rizik da nam metan svima presudi dramatično uvećava.

  'No doubt left' about scientific consensus on global warming, say experts  
 
Quote

The scientific consensus that humans are causing global warming is likely to have passed 99%, according to the lead author of the most authoritative study on the subject, and could rise further after separate research that clears up some of the remaining doubts.
Three studies published in Nature and Nature Geoscience use extensive historical data to show there has never been a period in the last 2,000 years when temperature changes have been as fast and extensive as in recent decades.

Dakle, imali smo globalno najtopliji zabeležen mesec na planeti. Naravno, "zabeležen" je operativna reč ali opet, protekli Jul je oborio nekakav rekord:


July confirmed as hottest month recorded

Dobra vest za promenu  :lol:


 The ozone layer is on track to completely repair itself in our lifetime


Mislim, dobra jer je primer kako su, jelte, Zemljani, primetili problem, shvatili šta je njegov uzrok (hloro-fluoro karbonati itd.) i zajednički se dogovorili da taj uzrok minimizuju i sad se problem rešava.

Evo i svežih loših vesti:


UN report: Climate change causes and impacts are increasing

Quote
The big picture: Data compiled by the World Meteorological Organisation for the report, to be presented to the UN summit, shows the average global temperature for 2015–2019 is on course to be the warmest of any equivalent period on record.
  • "It is currently estimated to be 1.1°Celsius (± 0.1°C) [about 2°F] above pre-industrial (1850–1900) times," the UN said in a statement accompanying the "United in Science" report.
  • To stop a global temperature rise of more than 2 degrees Celsius above pre-industrial levels and meet the goals of the 2015 Paris climate agreement, countries must triple climate emission cut targets, the report warns.
Key findings:
  • Accelerating climate impacts from melting ice caps to sea-level rise and extreme weather are responsible for the warming, researchers say, with the global average temperature increasing 1.1°C above pre-industrial (1850-1900) times and 0.2°C (or .36°F) warmer than 2011-2015.
  • Carbon dioxide concentrations in the atmosphere increased at a higher rate in the 2015-2019 period than in the previous 5 years and are on course to reach a record 410 parts per million this year.
  • Sea levels have risen an average of 5mm (0.2 inches) a year in the past 5 years, compared to 3.2mm (0.13 inches) a year on average since 1993, and much of the increase is from melting glaciers and ice sheets.
  • The Antarctic ice sheet's annual ice losses increased at least 6-fold, from 40 gigatonnes (Gt) per year in 1979-1990 to 252 Gt per year in 2009-2017.

Inače, kako često slušamo da se klimatolozi "ne slažu svi" oko toga kako se klima menja i jesu li ljudi za to krivi, te da propagandisti mogu da nam pričaju šta oće jer koriste naučni jezik da zasene  prostotu, evo detaljnog dokumenta pisanog za ljude koji NISU naučnici, kako bi se upoznali sa problemom i doneli informisane odluke:

   Jonathan Safran Foer: why we must cut out meat and dairy before dinner to save the planet


Quote
What I am thinking of is the fact that we cannot save the planet unless we significantly reduce our consumption of animal products. This is not my opinion, or anyone’s opinion. It is the inconvenient science. Animal agriculture produces more greenhouse gas emissions than the entire transportation sector (all planes, cars and trains), and is the primary source of methane and nitrous oxide emissions (which are 86 and 310 times more powerful than CO2, respectively). Our meat habit is the leading cause of deforestation, which releases carbon when trees are burned (forests contain more carbon than do all exploitable fossil-fuel reserves), and also diminishes the planet’s ability to absorb carbon. According to a recent report from the Intergovernmental Panel on Climate Change, even if we were to do everything else that is necessary to save the planet, it will be impossible to meet the goals of the Paris Climate Accord if we do not dramatically reduce our consumption of animal products.

Kad pogledaš u ambis i ambis pogleda u tebe.


Pun mi je torbak obrazovanih internetom. Sad bi trebalo da verujemo tupadžiji filozofu koji je znanje isisao iz malog prsta? Svetske probleme prave oni koji bi da proizvode po svaku cenu, a ne oni koji lože drva i ugalj. A tu politiku ti zastupaš. Potrošiće oni svaki litar nafte, eto pronašli su i da je nafta neorganskog porekla. Tvoja polja soje uništavaju pčele, jedeš sejtan (čist gluten) jer će izmisliti da je tradicionalna kineska hrana, a našli su način kako da ga prodaju naivnima. Kad bismo sabrali energetske troškove tvog tanjira, moja šnicla je jeftina.


Metan i CO2 su znak života, a ne najava smrti. Gde ih ima u svemiru ima i života. Kad propadnu neoliberalne teorije, a propašće sigurno, naučićemo da ne proizvodimo đubre. Maline ne moraju u SAD da se uvoze iz Čilea, tankeri ne moraju da voze preko okeana proizvode koje možemo uzgajiti u sopstvenom dvorištu. Jednostavno je samo se nekome ne isplati. Biznis pre svega. Zato, svaki put kad pomisliš da su krave krive za sve toneš u neizmernu glupost  i mogao bi toga da se poštediš.
Never argue with stupid people, they will drag you down to their level and then beat you with experience. - Mark Twain.
