00:00They would be advised to plan your vacation in Miami Beach,
00:04because all this area could be submerged in 75 years.
00:09And Florida is not an isolated case.
00:12Some regions of Louisiana, California and the state of Washington
00:15figure out also among the first areas of the United States
00:18that the mountains of the sea menace seriously.
00:21If you live in the United States, you can verify by yourself
00:23if your address is in a city threatened to disappear.
00:26You can click Sea Level Rise Viewer on Google.
00:30You can access the National Oceanic and Atmospheric Administration
00:35which allows you to visualize the aspects
00:37that could take the coastal floods in the years to come.
00:41You can see this cloud in blue blue.
00:43These are the American American cities.
00:45I hear those that could be submerged from here to 2100.
00:50This scenario corresponds to the worst case,
00:52which is where the sea level reaches 3 meters.
00:55We hope that this does not happen.
00:58You know it without a doubt.
01:00The high level of the sea level is a direct consequence
01:02of the global warming.
01:04As soon as the Earth is warming up,
01:06the clouds of the north and the south are flowing,
01:09liberating an important quantity of water in the oceans.
01:12In other words,
01:13the cold water is dilated,
01:14occupant more space.
01:16The effect combined of these two phenomena
01:17are increasing the levels of the sea level of the sea level.
01:21The sea level of the sea level of the sea level
01:22could even go through some cities.
01:26The current data show that the level of the sea level
01:29could rise to around 1,80 m to the 2100.
01:32This phenomenon may cause enormous results on the plains.
01:36It is not only in case of a stormy or a stormy stormy.
01:40Even by clear time, some zones might not be found under the eaux.
01:44This is an essential question.
01:47How do we measure precisely the height of the ocean?
01:50Today, experts come to measure the level of the sea with a remarkable precision,
01:55thanks to satellites satellites.
01:57It is a particular type of radar,
02:00made to measure the altitude of a surface.
02:02In chronometring the time that puts a radar to descend to the ocean,
02:06then to rebondir, this instrument determines the exact height of the sea.
02:11In crossing these data with the precise position of the satellite,
02:15scientists can cartograph the least variations of the marine level at the planet.
02:20At the current time, the previsions in terms of the inondations côtières
02:23reveal a surprising constat.
02:25The rise of the elevation of the sea level at the world has doubled in the space of 30 years.
02:30Many online tools can illustrate the breadth of this phenomenon could achieve in the years.
02:36The visualizer of elevation of the sea level, mentioned earlier,
02:40is focused on the territory of the United States.
02:42But if you reside elsewhere,
02:43you can all the same know if your address is threatened.
02:46It is enough to consult the interactive card proposed by Climate Central.
02:50In regulating the level of the water level at 3 meters above the line of the high seas,
02:54you can see that many countries may be severely touched.
02:58Now let's look at the South America.
03:00In Argentina, for example,
03:02a mountain of sea level inondering the large areas of the province of Buenos Aires.
03:06In heading to Brazil,
03:08you can see that many cities,
03:10such as Rio de Janeiro,
03:12would be concerned.
03:12Maybe we would have to give our adieu
03:14to the famous trottoir
03:16to the motifs ondulés of Copacabana.
03:18The two airports of the city
03:20would also be submerged.
03:22The situation is not yet worse in Europe.
03:25The major cities such as Lisbonne,
03:27Valence
03:28or Rome
03:29might be partially under the sea.
03:32But it is certainly in the Netherlands
03:33that the peril is the most serious.
03:36Currently,
03:37a half of the country
03:38is already under the level of the sea,
03:40and about the half of the sea
03:41is above 90 cm.
03:43An elevation of the marine level
03:45would therefore expose the territory
03:47to major risks.
03:49All this red zone,
03:50including Amsterdam and Rotterdam,
03:53would be englouted
03:54if the oceans climb up to 3 m.
03:57Fortunately,
03:58the Bays-Bas are probably the country
03:59in the world's most experienced
04:00in the fight against the assaults of the sea.
04:03For decades,
04:03they are facing this peril
04:05thanks to great infrastructures,
04:08gigantic giants,
04:09moulins-à-vent
04:10and digues colossales
04:11made up to control the sea.
04:13Their efforts
04:14allowed to conquer
04:15around 20%
04:16of their territory on the sea.
04:18Yes,
04:19they are well and well in expansion.
04:20However,
04:21other nations
04:22are exposed
04:22to threats
04:23even more serious.
04:24According to some estimates,
04:26about 5 countries
04:27may be disappeared
04:28in a close future.
04:30Let's start with the Fidji.
04:32This tropical paradise
04:33adoré des voyageurs.
04:35This country
04:35is particularly vulnerable
04:37because of its
04:38airs very low.
04:39If the climate warming
04:40reaches extreme levels,
04:42the level of the sea
04:43could climb up
04:44to 1,80 m
04:45d'ici to 2100.
04:46In other words,
04:47the archipel
04:48is located
04:48in the middle of the Pacific,
04:50where the most violent
04:52storms
04:52end up with a growth growth.
04:54This means
04:55that the inhabitants
04:56need to attend
04:57to more frequent flood
04:58and they react
04:59already with determination.
05:01To protect
05:02the plains
05:02against erosion,
05:03some communities
05:04align with old
05:05pneus
05:06to avoid
05:07that the sable
05:08not disappear
05:09under the waves
05:10of reinforcements.
05:11Other plants
05:11can reduce
05:14the height
05:15of 30%
05:16and 1%
05:17in average.
05:18These trees
05:19also play an important role
05:20against the force
05:21of the wind
05:22during the cyclones.
05:24Then comes
05:24the Vanuatu
05:25in the red list
05:26of the river
05:27of the river
05:27This archipel
05:28située
05:29between the Australia
05:29and the Fidji
05:30could be englouti
05:31rather than
05:32what we imagine.
05:32And the authorities
05:33take déjà
05:34measures concrètes.
05:35The Vanuatu
05:36was one of the first
05:37countries
05:37in the Pacific
05:38to relocalise
05:39a community
05:40to more sure.
05:41In 2005,
05:43the inhabitants
05:43exposed to the risk
05:44on the Septentrionale
05:46of Tegua
05:46were displaced
05:47to the hautes
05:48less vulnerable.
05:48The heat
05:49persistant
05:50expose the country
05:52to the cyclones
05:52tropicaux
05:53more intense.
05:54This will lead
05:55to more abundant
05:57inondations
05:58and risks
05:59accrues
05:59for the
05:59buildings
06:00and infrastructure.
06:01The Marshalls
06:02are also faced
06:03a serious threat.
06:05This country,
06:06which counts
06:06about 39.000 inhabitants,
06:08is located opposite
06:09the United States
06:10on the globe.
06:11It is a very low nation
06:12built in a
06:12very low nation
06:13based on a
06:15steeple
06:15of the world.
06:16According to the NASA,
06:17the level of the sea
06:18has increased
06:19about 10 cm
06:20over the last 30 years
06:21and could still
06:23increase
06:23about 19 cm
06:25over the next 30 years.
06:26This is not a
06:27anodine detail.
06:28If no measure
06:29is taken,
06:30the island could
06:31have more than 100
06:32days of inondations
06:33annually
06:33until the end of the century.
06:35The inhabitants
06:36regretted
06:36to lose their homes.
06:38The studies
06:38say that
06:3940% of the buildings
06:41located at Majuro,
06:42the capital
06:42risk
06:43to be submerged
06:44in the years
06:45to come.
06:46However,
06:47the country
06:47does not
06:47raise their arms
06:48and reinforce
06:49its infrastructure.
06:51The island
06:52are also
06:52slowly engleding
06:53by the sea.
06:55This region
06:56has an elevation
06:57almost three times
06:58higher than the world.
07:00During the time,
07:01images satellites
07:02have revealed
07:03that five
07:03have already
07:05disappeared
07:06under the sea.
07:07Despite that,
07:08the inhabitants
07:08try to protect
07:09their territory
07:10by building
07:11stone walls
07:12and planting
07:13mangroves
07:14to prevent
07:14the marine intrusion
07:18The most critical case
07:20could be
07:20Tuvalu
07:21which may become
07:22the first country
07:23entirely inhabited
07:24because of the
07:25montée
07:25of the sea.
07:26This chain
07:27d'îles
07:27between Australia
07:29and Hawaii
07:30surpasses
07:312,80 m
07:32above the sea.
07:34The most close
07:35is a place
07:36named Fongafal.
07:37The earth
07:38is about
07:38about 20 m
07:39of large.
07:40You understand
07:41the extreme fragility
07:42of the situation.
07:43Before the arrival
07:44of the Great Marais,
07:45the agricultural land
07:46are limited
07:47to the country
07:47are deteriorated
07:49by the infiltration
07:50of the sea.
07:50These islands
07:51incarnate
07:52a strong example
07:52of resilience
07:53reminding
07:54that the cities
07:54are not necessarily
