Stop Global Warming

[Hierarchia]

Ma, necemo svi umrijeti. Jos cemo se malo izivljavati nad prirodom planete nam Zemlje, pa cemo se preseliti svi lagano na fucking Mars! Ustvari, niko nece umrijeti...

Imas li VIZU za Mars

Za Mars treba viza, a za vizu Mastercard sa pozamasnom cifrom.

ma joj, nekoliko indonezijskih otoka vec je iseljeno zbog povecanja nivoa mora.

A koji su to otoci please? Da nisu oni što ih je poravnio tsunami? Ne valjajte tračeve ovdje.

promjene temperature vec su uzele danak i unistile mnogo osjetljivih zivotinjskih i biljnih zajednica.

Kao koje naprimjer? Koliko se ja razumijem u biologiju, život najviše buja tamo gdje je toplo i gdje ima dosta vode. Šta ima loše da se južni pol ili Sibir pretvore u područja pogodno za život?

u dalmaciji su se pojavile "pijavice", meteoroloski fenomen koji nije zabiljezen do prije par godina.

u bosni nije grmilo ljeti do prije par godina.

gleceri su vec poceli da se tope i ove godine njohov volumen je najmanji otkad se prati.

Uvijek su se topili a i što će nam. Nama treba voda.

australijsko ljeto vise to nije: od prosjecnih 45 ove godine je bilo 15...

Da ovo nije globalno zahlađenje?!

mogu ja ovako do sutra. dokaza je milion, samo se okrenite i pogledajte kisu u sred zime i ozelenjele izdanke. na takve izdanke dovoljno je da zapada snijeg 2 dana i da odu kvragu.

My friend, od snijega se nemože živjeti.

Globalno zagrijavanje za nas koji cemo za oko 50 godina otprilike biti pod zemljom nema nikakvo znacenje. Mozda za nasu djecu, a i to tesko.

Toliko o svjesnosti. Najgore je ponasanje tipa ma boli me qrac, sa mnom je sve pocelo i sa mnom i zavrsava.

A šta ti, ja i bilo ko drugi znamo o globalnom zagrijavanju? Osim što znamo da se Zemlja polagano zagrijava niko ama baš niko nema pojma kako se to može odraziti na život. Bilo je i prije dosta perioda zagrivanja planete. U to vrijeme na Južnom polu je bujalo drveće a danas je beskorisna masa leda. Globalno zagrijavanje bi se moglo pozitivno odraziti na život ljudi u smislu pogodnijih temperatura za proizvodnju hrane u područjima gdje je to danas misaona imenica.

Poenta je ovo: planeta Zemlja je od svog postojanja prolazila kroz cikluse značajnog zagrijavanja i hlađenja. Ako mene pitate, meni je globalno zagrijavanje draže od globalnog zahlađenja. Prije okok 20000 godina cijela Evropa i Sjeverna Amerika su bili pod 2-3 kilometra leda i tako je ostalo hiljadama godina. Je li to što hoćete u Evropi danas?

[rashomon]

Je li ovo republikanski pristup problemu!

Znači li to ako hoćemo normalnu planetu zemlju koja funkcioniše na normalnim osnovama "da smo teroristi pingvini koji bi da otjeraju " jebene amerikance kao najveće stvaraoce CO2 na planeti!

Globalno zagrijavanje se očituje ne samo kroz globalni porast temperatura i "neobično" vrijeme za "ovo doba godine", već i kroz količinu radijacije/zračenja, albedo i čitavo mnoštvo drugih pojava!

Zemlja apsorbuje energiju - kratko-talasno zračenje - sunca. Jedan dio toga se reflektuje u formi dugo-talasnog zračenja koje se odbija od zemljinu atmosferu nazad u svemir, uz jedan dio koji ipak prolazi kroz atmosferu i utiče na temperaturu i klimatsku slike zemlje!

Globalno zagrijavanje, u skladu s tim, je uzrokovano LJUDSKOM produkcijom CO2, što nije prirodno i kreira viškove dugih talasa koji se povećavaju u našoj atmosferi i zagrijavaju kompletnu planetu!

Objašnjeno je hiljade i hiljade puta!

[array]

Rasho, da si pročitao malo bolje moj post vidio bi da ja ne negiram globalno zagrijavanje. Samo sam rekao da globalno zagrijavanje u stvari može biti dobro za ljudsku rasu. Nijedan naučnik nije niti može predviditi kako će se globalno zagrijavanje odraziti na klimu. Promjena može biti pozitivna za većinu ljudi.

[Hierarchia]

Array, dobra argumentacija i vrlo rijetka pojava za ovaj forum.
Rashomon, dodala bih da nije vazno ko vise unistava planetu, mi ili Ameri - we're in this shit together- Zasto sve odmah ideologizirati.
Na kraju, ako cemo uzeti i neku filozofsku stranu svega toga - do global warminga je logickim slijedom razvoja civilizacije moralo doci.

Consequence: drought and wildfire
Warmer temperatures could also increase the probability of drought. Greater evaporation, particularly during summer and fall, could exacerbate drought conditions and increase the risk of wildfires.

Consequence: more intense rainstorms
Warmer temperatures increase the energy of the climatic system and lead to more intense rainfall at some times and in some areas.

Warning signs today

* National annual precipitation has increased between 5 and 10 percent since the early 20th century, largely the result of heavy downpours in some areas.

* Vermont, New Hampshire, Rhode Island, and Massachusetts each got more than double their normal monthly rainfall in June 1998.

* Severe flooding in the Texas, Montana, and North Dakota during the summer of 2002 caused hundreds of millions of dollars in damage.

Consequence: deadly heat waves and the spread of disease
More frequent and more intensive heat waves could result in more heat-related deaths. These conditions could also aggravate local air quality problems, already afflicting more than 80 million Americans. Global warming is expected to increase the potential geographic range and virulence of tropical diseases as well.

Warning signs today

* In 2003, extreme heat waves caused more than 20,000 deaths in Europe and more than 1500 deaths in India.

* More than 250 people died as a result of an intense heat wave that gripped most of the eastern two-thirds of the United States in 1999.

* Disease-carrying mosquitoes are spreading as climate shifts allow them to survive in formerly inhospitable areas. Mosquitoes that can carry dengue fever viruses were previously limited to elevations of 3,300 feet but recently appeared at 7,200 feet in the Andes Mountains of Colombia. Malaria has been detected in new higher-elevation areas in Indonesia.

WARMING WATER

Consequence: more powerful and dangerous hurricanes
Warmer water in the oceans pumps more energy into tropical storms, making them more intense and potentially more destructive.

Warning signs today

* The number of category 4 and 5 storms has greatly increased over the past 35 years, along with ocean temperature.

Consequence: melting glaciers, early ice thaw
Rising global temperatures will speed the melting of glaciers and ice caps, and cause early ice thaw on rivers and lakes.

Warning signs today

# At the current rate of retreat, all of the glaciers in Glacier National Park will be gone by 2070.

# After existing for many millennia, the northern section of the Larsen B ice shelf in Antarctica -- a section larger than the state of Rhode Island -- collapsed between January and March 2002, disintegrating at a rate that astonished scientists. Since 1995 the ice shelf's area has shrunk by 40 percent.

# According to NASA, the polar ice cap is now melting at the alarming rate of nine percent per decade. Arctic ice thickness has decreased 40 percent since the 1960s.

# In 82 years of record-keeping, four of the five earliest thaws on Alaska's Tanana River were in the 1990s.


Consequence: sea-level rise
Current rates of sea-level rise are expected to increase as a result both of thermal expansion of the oceans and of partial melting of mountain glaciers and the Antarctic and Greenland ice caps. Consequences include loss of coastal wetlands and barrier islands, and a greater risk of flooding in coastal communities. Low-lying areas, such as the coastal region along the Gulf of Mexico and estuaries like the Chesapeake Bay, are especially vulnerable.

Warning signs today

* The current pace of sea-level rise is three times the historical rate and appears to be accelerating.

* Global sea level has already risen by four to eight inches in the past century. Scientists' best estimate is that sea level will rise by an additional 19 inches by 2100, and perhaps by as much as 37 inches.


Consequence: ecosystem shifts and species die-off
The increase in global temperatures is expected to disrupt ecosystems and result in loss of species diversity, as species that cannot adapt die off. The first comprehensive assessment of the extinction risk from global warming found that more than one million species could be committed to extinction by 2050 if global warming pollution is not curtailed. Some ecosystems, including alpine meadows in the Rocky Mountains, as well as tropical montane and mangrove forests, are likely to disappear because new warmer local climates or coastal sea level rise will not support them.

Warning signs today

* A recent study published in the prestigious journal Nature found that at least 279 species of plants and animals are already responding to global warming. Species' geographic ranges have shifted toward the poles at an average rate of 4 miles per decade and their spring events have shifted earlier by an average of 2 days per decade.

* In Washington's Olympic Mountains, sub-alpine forest has invaded higher elevation alpine meadows. In Bermuda and other places, mangrove forests are being lost.

* In areas of California, shoreline sea life is shifting northward, probably in response to warmer ocean and air temperatures.

* Over the past 25 years, some penguin populations have shrunk by 33 percent in parts of Antarctica, due to declines in winter sea-ice habitat.

Africa
Grain yields are expected to decrease, and there will be less water available. Desertification will be worsened by reductions in average annual rainfall, especially in southern, north and west Africa. Coastal settlements in Nigeria, Senegal, Gambia, Egypt and along the southeast African coast will be hit by rising sea levels and coastal erosion.
Asia
High temperatures, drought, floods and soil degradation will probably diminish food production in arid and tropical parts of Asia. Northern areas may see an increase in productivity. Rises in the sea level and more intense tropical cyclones will likely displace tens of millions of people in low-lying coastal areas of temperate and tropical Asia.
Europe
Southern Europe will become more prone to drought. In other areas, flood hazards will increase. Half of Alpine glaciers could disappear by the end of the 21st century. Heat waves may change traditional summer tourist destinations and less reliable snow conditions may hurt winter tourism. Agricultural productivity may increase in northern Europe, but decrease in southern Europe.
Latin America
Floods and droughts will become more frequent. Yields of important crops will probably decrease in many parts of Latin America. Subsistence farming in northeastern Brazil could be threatened. Exposure to diseases such as malaria and cholera likely will increase.
North America
Food production could benefit from modest warming, but there will be strong regional effects such as a decline in Canada's Prairies and the U.S. Great Plains. Sea level rises could increase coastal erosion, flooding and lead to more storm surges, particularly in Florida and the Atlantic coast.

Diseases like malaria, dengue fever and lyme disease may spread in North America and there could be more heat-related deaths.
Polar
Climate change in polar regions is expected to be among the largest anywhere on Earth. Already the extent and thickness of Arctic sea ice have decreased, permafrost has thawed and the distribution and abundance of species has been effected. The trends may continue even long after greenhouse gases are stabilised and cause irreversible impact on ice sheets, global ocean circulation and sea levels.
Small island states
A projected sea level rise of 5 millimetres per year for the next 100 years will increase coastal erosion, damage to ecosystems, loss of land and dislocation of people. Coral reefs will be damaged and fisheries harmed. Tourism -- an important source of income -- will probably face severe disruption from climate change and rising sea levels.
Australia and New Zealand
A more mixed picture. Impact on some temperate crops may initially be positive, but this will likely alter with further climate change. Much of the region may dry out, but there will also be more, intense heavy rains and cyclones resulting in flooding, storm and wind damage.

Detalje iz filma Neugodna istina (An Inconvenient Truth) autora Al Gorea mozete pogledati u prezentaciji (u programu Microsoft PowerPoint) koja je postavljena na web adresi:

http://www.balkanshare.com/download.php?file=789752

Svakom bi preporucio da pogleda pomenuti film, gdje je iznesena sva sila naucnih cinjenica, a koje neupitno ukazuju da se ubrzano krecemo ka planetarnoj ekoloskoj katastrofi. Interesantno je da u filmu argumentovano tvrde da cemo mi Evropljani klimatskim promjenama biti vraceni u ledeno doba ako se u cijelosti istopi led Grenlanda. Mozda je i zato, ovih godina, i tolika frka u citavoj Evropskoj uniji oko izgradnje elektrana za proizvodnju elektricne energije.

Konacno, objasnjenje globalnog zatopljavanja:



Elem, autorica pisma kaze da je razlog za globalno zatopljavanje prelazak na ljetno racunanje vremena (koje je ove godine u USA pocelo mjesec dana ranije nego obicno). Posto dani "traju duze", sunce ima vise vremena da przi, i eto belaja. Kaze, urota liberalnog americkog kongresa...

Juce je na Discovery kanalu pocela mini-serija u 11 epizoda o nasoj planeti, koja se zove jednostavno Planet Earth.
Serija je snimana 5 godina i pokriva sve aspekte zivota na Zemlji (planine-pustinje-okeane....). Snimane su scene i zivotinje koje nikada do sada nisu snimane. Povod za snimanje serije je sve ubrzanije globalno zatopljavanje nase planete, koje ce ubrzo dovesti do istrebljenja nekih zivotinjskih vrsta, kao i potpuno promijeniti sliku planete ovakve kakve je mi znamo. Producenti ovog fantasticnog dokumentarca su zeljeli da neke slike i neke vrste ostanu zauvijek zabiljezene bar na filmskoj traci....a DVD se moze kupiti i moze posluziti onima koji ce tek imati djecu, jer ce ova planeta izgledati mnogo drugacije za nekih 20-tak godina....

Ljudi moji nema globalnog zagrijavanja. Pa znate li da se nekad sezona kupanja u Sarajevu otvarala 1. maja. Čovjek ne može da utiče na klimu globalno, već na mikroklimu lokalno kad se digne smog u kotlinama (temperaturna inverzija). Znate li da je grenland prije 1000 godina bio naseljen' Naselili ga Vikinzi i bili tamo do prije 800 godina. Uspijevao je tamo i kukuruz, bila naselja (ostale su ruševine utvrđenja), pa i sam naziv znači da je to nekad bila zelena zemlja. A nije bilo zagađenja. Klima se stalno mijenja i postoje topli i hladni periodi. Mi smo upravo izašli iz malog ledenog doba (krajem 18 vijeka) i opet ulazimo u sljedeće hladno razdoblje. Zna se da sunčeve pjege mogu malo da utiču na klimu. Atmosfera je ogromnog volumena i ne može se zagaditi toliko da se izmijeni klima. Protokol iz Kyotta je bezvezarija. To nije naučni metod. Kako izmjeriti nivo otpuštanja štetnih gasova? To je nemoguće. Gdje se to mjeri? Nema tehnologa koji će to potvrditi. Može se mjeriti nivo zagađenja samo od nekih postrojenja (mali je to broj), a nikako globalno. Postoji kvazinauka koja se prifilira i propagira putem strogo kontrolisanih medija (National Geografic i ostale budalaštine sa kvazi-naukom) Kako izmjeriti koja država najviše zagađuje okolinu? Gluposti, ali ljudi se u to NE RAZUMIJU, a "naučno" komentiraju. Gledajući TV svi su postali stručnjaci za zagađenje. Zabranili su freon i hoće da zabrane gas SF6 u industriji. Pa ti su gasovi (konkretno SF6) teži od zraka i kako onda da uništavaju ozon na visini od par desetina kilomatara. Je li to naučni metod? ČOVJEK NE MOŽE DA UTIČE NA KLIMU. Dokaz je Grenland i njegova naseljenost prije 1000 godina. Poslije je došlo malo ledeno doba i ljudi su se povukli odozgo. Klima se stalno mijenja, ali vrlo malo i vrlo sporo i treba prestati trabunjati o globalnim promjenama. Bilo je promjena i prije i nije svijet nastao i počeo od našeg doba. I prije su ljudi živjeli i upamtili su razne klimatske promjene. Ovo sad je samo zahtjev industije za pokretanje novih grana i sve je to u funkciji zarade.

Global Warming
May Be Spurring
Allergy, Asthma
Dr. Ziska's Ragweed
Loves Carbon Dioxide;
Toxic Pollen in Cities?
By GAUTAM NAIK
May 3, 2007; Page A1

There's growing scientific evidence that global climate change is linked to the dramatic rise in allergies and asthma in the Western world.


Studies have found that a higher level of carbon dioxide turbocharges the growth of plants whose pollen triggers allergies. In 2001 Lewis Ziska planted ragweed -- the main cause of hay fever in the fall -- at urban, suburban and rural sites near Baltimore. The plots had the same seeds and soil and were watered in the same way. Yet the downtown plants soon exploded in size, flowering earlier and producing five times the pollen of rural plants. The city pollen was a lot more toxic, too. The likely cause? The city plants experienced warmer temperatures and 20% more carbon dioxide, the effect of more cars and pollution.

"We can see the changes now, and they already have implications for public health," says Dr. Ziska, a plant physiologist at the U.S. Department of Agriculture. Allergies and asthma are closely linked; more than 70% of asthma sufferers also have allergies.

The Intergovernmental Panel on Climate Change, a group of the world's leading climate researchers, will address the issue in its August report. According to Bettina Menne, a doctor at the World Health Organization and a lead author of the chapter on climate change and health, the report will say that higher temperatures and carbon-dioxide levels have increased the abundance of pollen, known to trigger allergies and worsen asthma. It will also conclude that spring, when allergy-causing tree pollen is at peak levels, has been arriving 10 to 15 days earlier over the past three decades, a trend expected to continue in coming years.

MORE ON RAGWEED AND GLOBAL CHANGE RESEARCH



Read the report1 Dr. Ziska and his colleagues wrote on ragweed and climate change: "Cities as Harbingers of Climate Change."

Dr. Ziska and his colleagues work at the Agricultural Research Service, a division of the U.S. Department of Agriculture. Read more about their research3 into climate change and crop systems."We can assume that allergic disorders are starting earlier because the pollen season starts earlier," Dr. Menne says. "Climate change contributes to the problem, but we don't exactly know by what amount." The upcoming IPCC report remains inconclusive on whether pollen is becoming more toxic.

For years, scientists have tried to explain the big increase in allergies and asthma in Western countries. Today, roughly 35 million Americans have seasonal hay-fever allergies and about 20 million suffer from asthma. Even though the air in many cities is much cleaner than in the past, the prevalence of hay fever has increased in the U.S. over the past few decades. In 2004, asthma affected more than 6% of the American population, up from a little over 3% in 1980, according to the U.S. Centers for Disease Control and Prevention in Atlanta.

Childhood asthma is increasing at an even-faster rate. The percentage of children with asthma jumped to 9% in 2005 from 3.6% in 1980, according to the CDC.

In 2004, a Harvard Medical School study linked the childhood asthma "epidemic" among inner-city youths to climate change. Stating that higher carbon-dioxide levels in cities promote pollen production in plants, fungal growth, and opportunistic weeds, the study noted that asthma among preschool children grew 160% between 1980 and 1994, more than double the increase for the overall U.S. population.

Much research remains to be done. No one has measured populations of allergy-inducing plants nationwide to establish how pollen levels have changed over the years.

'Interesting Hypothesis'

The climate-change connection is "an interesting hypothesis that deserves further research," says Darryl Zeldin, a senior scientist at the National Institute of Environmental Health Sciences, part of the National Institutes of Health. "All the data isn't in."

Some scientists blame dust mites, mold, and other indoor allergens. Others point to specific pollutants in the air, changed diets, genetic susceptibility and higher obesity rates. Another idea, called the "hygiene hypothesis," argues that people today suffer from more allergies because they faced less exposure to infectious agents in childhood.

"I do think that climate change contributes" to the rise in allergies and asthma, "but it's not the only answer," says Christopher Randolph, an allergist and clinical professor at Yale University.



The links between climate change, allergies and asthma are multilayered. Higher carbon-dioxide levels, the result of human activity, are believed to warm the atmosphere, which in turn affects the geographic location and growing season of allergy-producing plants. A higher level of carbon dioxide separately spurs the growth of ragweed and other allergy culprits. Studies indicate it may make pollen more potent as well. Over the longer term, other potential impacts of global climate change -- changes in precipitation, more intense hurricanes -- could affect the growth of molds, which also cause allergies, or affect how far plant pollens are dispersed.

In recent years, pollen counts have hit record levels in many urban areas. A pollen count of 150 grains per cubic meter or more is very high; many U.S. and European cities sometimes show counts in the thousands. The season for birch -- a major hay-fever nuisance in Western Europe -- has arrived five days earlier each decade over the past 30 years.

It isn't surprising that rising carbon-dioxide levels and warming climes will alter the biology, chemistry and geographical distribution of plants. After all, many plants thrive when there's more carbon dioxide in the air, or when it's warmer.

But the latest research has found that such shifts especially boost invasive plants, including allergy culprits like ragweed. "No one had thought in the 1990s that higher carbon-dioxide levels would have a disproportionate effect on weeds," says Paul Epstein, associate director of the Center for Health and the Global Environment at Harvard Medical School. "It came as a surprise."

In the U.S., about three-quarters of the 35 million people who suffer nasal allergies are primarily allergic to the pollen of ragweed, whose season extends from mid-August to October. Common ragweed is a gray-green plant that can attain a height of about 3 feet. A North American native, it often erupts along roadsides, river banks and in urban lots disturbed by construction or digging.

Over the past few years, ragweed has begun spreading through Europe. Barely seen on the Continent a decade ago, ragweed can now be found in Eastern Europe, especially in Hungary, and also in France, Italy, the Netherlands and Scandinavia.

"It's a good example of a plant changing its distribution because of climate change," says Jean Emberlin, director of the National Pollen and Aerobiology Research Unit in Britain.

A host of independent studies draw a link between higher carbon-dioxide levels and weed growth. A paper published in 2002 by Harvard's Dr. Epstein and his colleagues showed that a single ragweed plant, which normally produces one billion pollen grains per season, produces 61% more when its exposure to carbon dioxide is doubled in a lab setting.

At the Jasper Ridge Biological Preserve in the eastern foothills of California's Santa Cruz mountains, scientists from Stanford University mimic future global-warming conditions by using artificial heaters and bombarding plants with carbon-dioxide emissions. Their key finding: Higher amounts of the gas fuel weed growth, and drive out native flora.


Lewis Ziska
Weeds grow faster and bigger in cities, amid higher CO2 and temperature levels.
Some of the most dramatic results have been obtained by Dr. Ziska. A researcher at the USDA's Crop Systems and Global Change lab in Beltsville, Md., Dr. Ziska spent several years trying to draw attention to how changing concentrations of carbon dioxide were likely to affect crop and plant life. No one seemed interested. In early 1999 Dr. Ziska, who suffers from ragweed allergies and asthma himself, had an idea: Would people pay more attention if he could show that rising carbon-dioxide levels affected their health?

Wearing a face mask to protect himself from the pollen, Dr. Ziska began to cultivate ragweed in large aluminum chambers at three different levels of carbon-dioxide concentrations. The first was 280 parts per million of air, the level that existed before industrialization. For the present era, he set the level to 370 parts per million. He also experimented with 600 parts per million, a conservative estimate for the carbon-dioxide concentration expected by the end of the century.

Over the course of a year, Dr. Ziska found that each ragweed plant produced 21 grams of pollen at the end-of-century level -- almost twice that produced at the present-day level and more than four times that produced at the "pre-industrial" setting. Also, the higher the dose of carbon dioxide, the bigger the plant.

Dr. Ziska then decided he needed a "real world" setting. Driving around one day, he noticed large clumps of ragweed growing in empty lots and along the sides of the road. He realized that he had a ready-made setting for his experiment: Baltimore itself.

Urban Effect

Cities are subject to the "heat island" effect -- a dome of higher temperatures caused by the warmth absorbed, then reflected, by structures and pavement. Moreover, the greater number of cars means urban areas have more carbon dioxide than outlying ones. Dr. Ziska figured that if he could measure how ragweed and about 35 other plants grew in downtown Baltimore versus a suburban and rural plot, it would provide clues about how they might compete in a warmer, carbon dioxide-richer world.

Through his field experiment, Dr. Ziska found that ragweed seed emerged three or four days earlier at the urban site than at the rural one, which is 40 miles away. Plus, the plants were huge, weighing nearly 190% more at the city location compared with the rural spot. A lot more pollen was produced in Baltimore as well.

In 2005, two years after that study was published, Dr. Ziska and other scientists published research about a pollen protein that triggers an allergic reaction to ragweed. Chemical analysis showed that there was far more of the protein on the pollen of plants bathed in higher levels of carbon dioxide -- thus making it a lot more potent -- compared with pollen of plants exposed to lower amounts of the gas.

One recent afternoon, Dr. Ziska visited the rural site, near Buckeystown, Md. He strode over to a 12-foot-tall metal tripod, hung with a solar panel and electronic instruments, and checked several measurements. The carbon dioxide level was 395 parts per million and the temperature was 47 degrees Fahrenheit.

3-Foot-Tall Saplings

In the experimental plots of land, each about 5 square yards, several plants were starting to come up. But some of the most prominent were 3-foot-tall saplings of oak, astor and Norway maple, each of which can also trigger severe nasal allergies.

An hour later, Dr. Ziska was at the urban site, a fenced-off area in Baltimore's downtown science museum. Here, the instruments told a different story: The temperature was 53 degrees Fahrenheit and the carbon-dioxide level was a much higher 477 parts per million -- not far from the 500-level in the overall atmosphere expected by 2050, based on a conservative estimate.

Resilient as ragweed is, other plants can be tougher in the long run. After five years of running the Baltimore field experiments, Dr. Ziska found that the amount of ragweed growing in the urban location declined as hardier plants took over. Eventually, pollen-bearing trees -- the main source of spring allergies -- emerged dominant.

These trees are also flourishing. The saplings here were at least twice the size of the plants at the rural site, and already sprouting large leaves. Last year, one of the plants at the urban site, a weed called ailanthus, had become a 20-foot giant and had to be chopped down. Even now, the plants at the museum site are at least five years ahead in their growth compared with their counterparts at the rural location.

Then Dr. Ziska bent down and pointed to a handful of half-inch seedlings sprouting in one of the beds. "That's where ragweed came up last year," he said. "Looks like it's coming up again."

Cak i da globalnog zatopljavanja nema (a ima ga) ili da nije opasno (a jeste), trebalo bi ga (ili nesto slicno njemu) izmisliti i na njegov znacaj skretati paznju (pa i napuhati ako treba).

Nisi u pravu što se tiče alternativnih izvora energije. Nafta će uvijek imati primat. Samo će se malo više koristiti energija vjetra i sunca, ali njihov udio u ukupnom iznosu ne može prevazići udio uglja i nafte.
