Prica o globalnom zagrijavanju planete i ima nekog smisla,dok sve ostalo nema veze sa stvarnoscu,jer korijen cijele kampanje lezi u industrijskoj revoluciji u Kini i pokusaja prodaje tehnologije za ocuvanje okoline ,kao i samog removanja ekspanzije tog razvoja.
Navescu primjer mocvarnih povrsina na svijetu koje proizvode vise CO2 nego svi automobili.Niko neprica o tome,ali se naveliko prica o katalizatorima na izduvnom sistemu automobila.U industrijskim tehnokratskim krugovima se prica o katalizatorima koji bi Kina mogla trebala i morala da postavi na fabricke dimnjake koji nicu kao gljive nakon kise.

Ovo se donekle podudara sa mojim ranijim komentarima. Znate li da je po nezavisnim izvorima (Njemačka) od 2004 pala prosječna godišnja temperatura? Na snimku ledenjaka na Alpama se vidi da je došlo do njihovog oporavljanja. Nema dokaza o promjeni klime. Sve je u funkciji zajebavanja raje i na tome rade masovni mediji. Svaka hamša u Londonu, Sarajevu, Travniku, Muenchenu sve zna o globalnom zatopljavanju... HA, HA, HA...sekiracija wrote:Prica o globalnom zagrijavanju planete i ima nekog smisla,dok sve ostalo nema veze sa stvarnoscu,jer korijen cijele kampanje lezi u industrijskoj revoluciji u Kini i pokusaja prodaje tehnologije za ocuvanje okoline ,kao i samog removanja ekspanzije tog razvoja.

http://www.vecernji.hr/newsroom/zanimlj ... BEF5FCE0.2EKOLOGIJA Znanstvenici izračunali efekt uzgoja mesa na atmosferu
Krave zagađuju više od tvorničkih dimnjaka
Vruće vam je? Želite li smanjiti globalno zagrijavanje? Prestanite jesti meso! Zaključak je to istraživanja japanskoga Nacionalnog zavoda za stočne i pašnjačke znanosti u Tsukubi koje u broju od kolovoza objavljuje znanstveni časopis Animal Science Journal, a prenosi bruxelleski EurActiv.
Cilj istraživanja bila je procjena utjecaja uzgoja stoke na okoliš, a ustanovilo se, slikovito, da jedenje jednoga kilograma mesa proizvede više stakleničkih plinova od tri sata vožnje automobilom dok su vam kod kuće upaljena sva svjetla.
4,55 tona plina
Istraživači su proučili životni ciklus prosječne krave koja se uzgaja za meso, uključujući proizvodnju i prijevoz stočne hrane, upravljanje farmom i klaonicom, uklanjanje otpada te biološku djelatnost životinje. Mjerili su potrošnju energenata, proizvodnju metana u kravinu probavnome sustavu te zagađivanje voda otpadom s farme, što smanjuje sadržaj kisika i sposobnost upijanja CO2.
Od 4,55 tona stakleničkih plinova, za koliko ih je tijekom svojega kratkoga životnog vijeka “odgovorna” krava koja se uzgaja za meso, otprilike trećina otpada na metan koji ona ispusti u atmosferu iz svoga probavnog trakta, a većinu od preostale tri tone prouzroči uporaba energenata za proizvodnju i prijevoz stočne hrane.
Prijevoz mesa
Tome treba dodati zagađivanje ozračja prijevozom mesa što to istraživanje nije obuhvatilo jer se udaljenosti od klaonica do tržišta mogu jako razlikovati.
Kako se cini sve sto radimo pojacava zagrijavanje, cak i nacinom prehrane, nesto ne vidim u skorijoj buducnosti da su ljud sporemni da se odreknu mesa...

Napokon sam i ja imao priliku vidjeti film Al Gore-a "Unconvinient truth".
Osvrnuo bih se na samo jedan detalj - Al se u svom izlaganju poziva i na americko iskrcavanje na Mjesec. On je pametan covjek i on zna bolje od toga (sto je i prokriveno priznao u jednom intervjuu) ali izgleda da se opredijelio ici "linijom manjeg otpora" jer jos uvijek ~ 90% americkog/svjeckog ummeta je "jasno profilisano"
glede ovoga.
Izgleda da se u biznisu formiranja kriticne mase "istomisljenika" (da ne kazem sljedbenika) mora dodvoravati. Malo sam razocarat, al razumijem i oprastam.

Neko ima i koristi od rasta temperature...

Making a mint from Artic mammoths
September 19, 2007 - 11:54AM
One day, climate change could cost the earth. For now, it is a nice little earner for Russian hunter Alexander Vatagin.
In Siberia's northernmost reaches, high up in the Arctic Circle, the changing temperature is thawing out the permafrost to reveal the bones of prehistoric animals such as mammoths, woolly rhinos and lions that have been buried for thousands of years.
Private collectors and scientific institutes will pay huge sums for the right specimen, and bone-prospectors such asVatagin have turned this region, eight time zones from Moscow, into a palaeontological goldmine.
"Last year someone was paid 800,000 roubles [$37,000] for a mammoth head with two tusks in great condition," Vatagin said.
A brawny 45-year-old, Vatagin has a network of helpers: the fishermen and reindeer-herders of the klix Yukagir ethnic group, whose numbers have dwindled to about 800.
"I must have earned the respect of the Yukagir. Their shamans convened a council and decided to name me a Yukagir." He is now Yukagir No. 456.
These tribesmen are his "finders", fanning out across the vast emptiness of the tundra seeking valuable artefacts.
At regular intervals, Vatagin flies by helicopter to the main Yukagir settlement, Andryushkino, about 200 kilometres west of the local centre of Chersky, to view the merchandise.
Prehistoric bones are not very hard to find, he says. The permafrost is thawing and breaking up so rapidly that in certain places in the tundra bones poke out through the soil every few metres. Some just lie on the surface.
Vatagin pays between $10 and $190 for a kilogram of mammoth bones. But it takes a keen eye and local knowledge to find the really valuable stuff.
Tusks, sometimes curled almost into a circle and reaching up to five metres in length, are the most prized finds. A pair of good tusks is a rarity; two tusks and a well-preserved skull can be worth a fortune.
"If he is lucky, a local can earn 200,000 roubles in just one day," said Vatagin, who wears a massive silver ring with a mammoth's head engraved into it.
"To earn this money, he would otherwise have to toil for a year."
But for Vatagin it is not just about money. He himself dives into the ice-cold local rivers to look for relics. The cash he pays the Yukagir tribesmen gives them a living.
Many of the bones retrieved by Vatagin and his adopted tribe end up at the Ice Age Museum in Moscow. The museum makes no secret that scientific discovery goes hand-in-glove with business interests.
Museum official Alexander Svalov has on one of his fingers a ring identical to the one won worn by Vatagin.
The ring is the symbol of the National Alliance, a close-knit business run by entrepreneur Fyodor Shidlovsky. The company runs the museum, and holds government licences allowing it to excavate and export prehistoric relics.
Svalov, who is the chief executive of National Alliance, says a well-preserved tusk can sell to private collectors for up to $24,000, while a reconstructed mammoth skeleton can fetch between $180,000 and $300,000.
The bones make their way into museums in places such as the United States and South Korea. Now promising new markets are opening up in emerging economies such asChina too.
"Developing nations are now displaying huge interest in mammoths," says Svalov. "Their economies are growing, they have cash and are starting to develop their museums."
The permafrost thaw affects those rare outposts where humans have settled.
In Chersky, a town of 3000 people, apartment blocks have cracks running through their walls as the earth beneath them subsides. Many have been demolished as unsafe.
Sergei Davydov, a 52-year-old scientist, does not sell the bones he collects. He keeps them in his home in Chersky to study the effects of climate change, but also because they fascinate him.
"This tooth has an unusual bump here. The mammoth suffered from a terrible toothache. We can only imagine how he must have roared," says Davydov, tenderly rubbing a black tooth the size of a large shoe.
He displays his other finds: a mammoth's giant thigh bones, the horns of a woolly rhino, the jaws of an ancient horse and a cave lion's skull. Bison skulls crowned with sharp horns decorate the interior of his cosy wooden house.
Davydov acknowledges that rising temperatures in Siberia have been a boon for bone collectors. "As the permafrost thaws, we obtain yet more objects for study," he says.
But then he reflects: "From the point of view of humanity, it would have been better if this had never happened.".

Voditelj CNN je imao intervju sa Al Gorom, uhvatio sam samo kraj ali pravo mi se svidio... "...Mozda ne mozemo utjecati na rat u Iraku ili razvoj atomskog oruzja, ali danas svi imamo priliku biti Nobelovci. Svaki pud kada napustimo sobu mozemo pogasiti sva svjetla i aparate, zavrnuti slavine... Mozda se to cini sitnim i nebitnim za globalno zagrijavanje ali sve to zbrojeno ucinit ce mnogo."
Nije bas od rijeci do rijeci, ali zna se na sta je mislio.

Postoji mogucnost da Sjeverni pol ovog ljeta ostane bez leda
Postoji mogucnost da Sjeverni pol ovog ljeta ostane bez leda
WASHINGTON (AFP) - There could briefly be no ice at the North Pole this summer, a US scientist said Friday, an event that would mark a new stage in the melting of the Arctic ice sheets due to global warming.
"We could have no ice at the North Pole at the end of this summer," Mark Serreze, a scientist with the National Snow and Ice Data Center in Boulder, Colorado, told AFP in an interview.
"And the reason here is that the North Pole area right now is covered with very thin ice and this ice we call first-year ice, the ice that tends to melt out in the summer."
If the ice, albeit briefly, were to break up completely this summer it would be the first time this had happened in human history.
Serreze put the chances of this occurring at 50 percent -- if it does happen, in September "it's possible" that ships could sail from Alaska right to the North Pole
