It’s 1988, and scientist James Hansen has just testified
2
14329

Godina je 1988, a naučnik Džejms Hansen je upravo svedočio pred
00:18
to the United States Congress that global warming trends
3
18621
3042
Kongresom Sjedinjenih Američkih Država da je globalno zagrevanje
00:21
are caused by human activity,
4
21663
2041
posledica ljudske delatnosti
00:23
and will pose an increasing threat to humanity in the future.
5

i da će vremenom sve više ugrožavati čovečanstvo.
00:27
Well, well. That’s unusually prescient for a human.

Vidi ti to. Kako neuobičajeno pronicljivo za čoveka.

Doterana, laskava i skromna- baš kao i tradicionalna venčanica.
00:42
Commercials. Could anything be more insufferable?
9
42287
4500
Reklame. Da li postoji išta nepodnošljivije?
00:47
It’s 1997, and the United States Senate has called a hearing about global warming.
10
47079
5708
Godina je 1997, a Senat SAD-a je sazvao sastanak o globalnom zagrevanju.
00:52
Some expert witnesses point out that past periods in Earth’s history
11
52829
3750
Neki stručni svedoci ističu da su raniji periodi zemaljske istorije
00:56
were warmer than the 20th century.
12
56579
2250
bili topliji od 20. veka.
00:58
Because such variations existed long before humans,
13
58829
3708
Pošto su takve varijacije postojale mnogo pre ljudi,
01:02
the witnesses claim the current warming trend
14
62579
2375
svedoci tvrde da je i trenutni trend zagrevanja
01:04
is also the result of natural variation.
15
64954
3125
rezultat prirodnih varijacija.
01:08
Ah, there is something more insufferable than a commercial.
16
68288
4916
Ah, dakle postoji nešto nepodnošljivije od reklama.
01:13
Luckily for the humans, there’s one more expert witness.
17
73204
4542
Srećom po čovečanstvo, postoji još jedan stručni svedok.
Demon razuma
01:25
What are you looking at? We’re all dressed.
18
85996
2917
Zašto buljite? Svi smo obučeni.
01:28
At least we are by the logic you just used.
19
88913
3208
To jest, jesmo po logici koju si ti upravo koristio.
01:32
It’s as if you were to say apples and oranges are both fruits,
20
92121
4000
To bi bilo kao da kažeš da i jabuke i narandže spadaju u voće
01:36
therefore they taste the same.
21
96121
2083
i zbog toga imaju isti ukus.
01:38
Or that underwear, wedding dresses, and suits are all clothes,
22
98204
3917
Ili da su donji veš, venčanica i odelo odeća,
01:42
therefore, they’re all equally appropriate attire for a Senate hearing.
23
102121
4083
pa su zato podjednako prikladni za zasedanje Senata.
01:49
The European wars of the 19th century and World War I were all wars, right?
24
109288
5625
Evropski ratovi tokom 19. veka i Prvi svetski rat su ratovi, zar ne?
01:56
So World War I couldn’t be any more devastating than those other wars,
25
116371
5333
Dakle, Prvi svetski rat nije mogao biti destruktivniji od tih drugih ratova,
02:01
could it?
26
121704
1084
zar ne?
02:04
Let’s say two people have a fever.
27
124496
2250
Hajde da zamislimo da dve osobe imaju groznicu.
02:06
They must have the same disease that’s causing that fever, right?
28
126746
3750
One onda mora da imaju istu bolest koja je izaziva, zar ne?
02:13
Of course not. One fever could be caused by chicken pox,
29
133329
4417
Naravno da ne. Jednu groznicu je možda izazvla varičela,
02:17
the other by influenza, or any number of other infections.
30
137746
4125
a drugu grip ili neka druga infekcija.
02:24
Like your claim about rising global temperatures,
31
144621
3333
Kao tvoja tvrdnja o rastućoj globalnoj temperaturi,
02:27
these claims make a false analogy.
32
147954
2959
ove tvrdnje su primer pogrešne analogije.
02:30
You're assuming that because two phenomena share a characteristic,
33
150954
4209
Ti pretpostavljaš da samo zato što dva događaja dele jednu osobinu,
02:35
in this case warming, they are analogous in other ways,
34
155163
4666
u ovom slučaju zagrevanje, da su slučni i po drugim osobinama,
02:39
like the cause of that warming.
35
159829
2500
kao što je uzrok zagrevanja.
02:42
But there’s no evidence that that’s the case.
36
162871
2833
Međutim, ne postoji dokaz da je ta tvrdnja istinita.
02:45
Yes, there have been other warm periods in Earth’s history—
37
165704
3209
Da, postojali su i drugi topli periodi u istoriji Zemlje-
02:48
no one’s disputing that the climate fluctuates.
38
168913
3125
niko ne poriče da se klima vremenom menja.
02:52
But let's take a closer look at some of those older examples of global warming,
39
172038
4916
Hajde da bolje proučimo neke od tih starijih primera globalnog zagrevanja,
02:56
shall we?
40
176954
1042
šta misliš o tome?
02:58
The Cretaceous Hot Greenhouse, 92 million years ago,
41
178829
4084
Globalno zagrevanje za vreme krede, pre 92 miliona godina,
03:02
was so warm, forests covered Antarctica.
42
182913
3125
bilo je toliko toplo da je Antarktik bio pod šumama.
03:06
Volcanic activity was likely responsible for boosting atmospheric carbon dioxide
43
186038
5291
Najverovatnije je aktivnost vulkana izazvala porast ugljen-dioksida u vazduhu
03:11
and creating a greenhouse effect.
44
191329
2709
i prouzrokovala efekat staklene bašte.
03:14
The Paleocene-Eocene Thermal Maximum, 55 million years ago,
45
194038
5750
Paleocensko–eocenski toplotni maksimum je pre 55 miliona godina
03:19
was so warm, crocodiles swam the waters of the Arctic Circle.
46
199788
4583
bio toliko topao da su krokodili plivali u vodama Arktičkog polarnog kruga.
03:24
This warming may have been caused by the drying of inland seas
47
204371
3708
Ovo zagrevanje je možda nastalo zbog isušivanja epikontinentalnih mora
03:28
and release of methane, a potent greenhouse gas,
48
208079
3750
i oslobađanja metana, potentnog gasa staklene bašte,
03:31
from ocean sediments.
49
211829
2000
iz okeanskih sedimenata.
03:34
Even among these other warm periods, you’re making a false analogy.
50
214329
5459
Ti praviš pogrečnu analogiju čak i među ovim drugim toplim periodima.
03:39
Yes, they had natural causes.
51
219788
2291
Da, oni su imali prirodne uzroke.
03:42
But each had a different cause,
52
222079
1917
Ali svaki period je imao drugačiji uzrok
03:43
and involved a different amount and duration of warming.
53
223996
3917
i varirao je u količini i trajanju zagrevanja.
03:47
They’re as dissimilar as they are similar.
54
227954
2917
Koliko su slični toliko su i različiti.
03:51
Taking them together, all we can reasonably conclude
55
231121
3167
Kada ih sve uzmemo u obzir, sve što možemo da zaključimo
03:54
is that the Earth’s climate seems to change
56
234288
2625
je da se klima na Zemlji menja
03:56
in response to conditions on the planet.
57
236913
3458
zbog promene uslova na njoj.
04:00
Today, human activity is a dominant force shaping conditions on your planet,
58
240413
5416
Danas je ljudska aktivnost glavna sila koja oblikuje uslove na vašoj planeti
04:05
so the possibility that it’s driving global warming
59
245829
3167
zbog čega se mogućnost da ona izaziva globalno zagrevanje
04:08
can’t be dismissed out of hand.
60
248996
2458
ne može tako lako odbaciti.
04:11
I’ll grant that the more complicated something is,
61
251454
2750
Mada, što je nešto komplikovanije
04:14
the easier it is to make a mistaken analogy.
62
254204
3542
to je lakše napraviti pogrešnu analogiju.
04:17
That’s especially true because there are many different types of false analogy:
63
257746
5208
Ova tvrdnja se pokazala tačnom jer postoji mnogo vrsta pogrešne analogije:
04:23
that similar symptoms must share a cause,
64
263329
2542
da slični simptomi znače isti uzrok,
04:25
that similar actions must lead to similar consequences, and countless others.
65
265871
5042
da slične radnje dovode do sličnih posledica, i mnoge druge.
04:31
Most false analogies you’ll come across are far less obvious
66
271121
4792
Mnoge pogrešne analogije na koje ćeš naići su manje očigledne
04:35
than those comparing apples to oranges, and climate is notoriously complex.
67
275913
5916
od poređenja jabuka i narandži, a klima je veoma kompleksna.
04:41
It requires careful, rigorous study and evidence collection—
68
281829
4542
Ona zahteva oprezno, rigorozno istraživanje i sakupljanje dokaza-
04:46
and making a false analogy like this only impedes that process.
69
286371
5167
a širenje pogrešne analogije kao ove samo ometa taj proces.
04:58
It’s 2013, and the United Nations Intergovernmental Panel on Climate Change
70
298829
5000
Godina je 2013, a Međuvladin panel o klimatskim promenama Ujedinjenih nacija
05:03
has found, aggregating decades of research,
71
303829
2959
je pomoću decenija istraživanja zaključio
05:06
that there is more than a 95% chance the global warming trend
72
306788
3791
da postoji više od 95% šanse da je trend globalnog zagrevanja
05:10
since the mid-20th century has been driven by human activity,
73
310579
3667
od sredine 20. veka posledica ljudske delatnosti,
05:14
namely the burning of fossil fuels.
74
314621
2458
uglavnom sagorevanja fosilnih goriva.
05:18
You’re both pets,
75
318079
1584
Vas dvojica ste kućni ljubimci
05:19
and he likes living in water, so you should, too.
76
319663
4208
pošto on voli da živi u vodi, to mora da znači da voliš i ti.
