00:01Now the snow is completely exhausted.
00:07The change is extremely abrupt, I would say.
00:15The glacier begins to break more.
00:18The Sierra Neal Cocuy stops being a continuous lake.
00:22They divide into smaller fragments.
00:24That's what happens to the atmosphere.
00:29So, how do they respond?
00:32Change from solid to liquid.
00:36That's what's happening.
01:17The
01:18in Coyacá, in the bridge La Cueva. In the year, a little far, 1945,
01:27those streets are like in the Sierra Nevada that today is called Huicán y Cocuy.
01:34The landscape was beautiful, I mean, when I saw that snow, it was extremely
01:42splendid and all the people who lived there had a lot of respect to it,
01:47because it was like a myth of the gods, because it was populated in a time by indigenous,
01:52until when there was a conquest of the Spanish. So, their gods were the Sierra Nevada, the lagunas,
02:01and I, since I was very little, wanted to know what it was, what it was there,
02:05since four years I started to go to the snow, the impermeable clothes didn't exist,
02:11maybe a little bit of wool that one had in his house.
02:15I had a little hat, a little hat, a little hat that they formed, the parents,
02:23and the coticias didn't have one, because there was no way of money to have one,
02:28and I went away from the Sierra.
02:31To get there and see it, between the rocks, for me it was wonderful.
02:36That's why I always stay in the most beautiful lands of the world,
02:40I would say, what we know about the Sierra Nevada del Cocuy.
02:56To understand the last glaciers of the Sierra Nevada del Cocuyo Huicán,
03:02there is a context of thousands of years in the time.
03:07Hace 30.000 years, Colombia had some glaciers extremely extensive.
03:13We could say that the Sierra Nevada del Cocuyo had almost come here to Bogotá.
03:17In Colombia, above the 3.000 meters of altitude,
03:22those areas were covered by glaciers.
03:28The Sierra Nevada del Cocuyo, super extensa.
03:31The Central Cordillera, almost like a sierra of active volcanoes.
03:37O sea, everything above the 3.000 meters of altitude.
03:39At that time, which was a very cold time, was a glaciers.
03:45Later, then, there were several changes climatic changes,
03:48change the climate system of the Earth,
03:52and the glaciers, then, begin to melt.
03:56The Sierra Nevada del Cocuyo Huicán, as we call it,
03:59is in a very particular geographical position,
04:02that there are no other rivers in the country,
04:07which is at the limit of the region of the Orinoquia and the Andes region.
04:15It is at all the limit.
04:17That, then, allows us to respond to the climate of the Orinoquia and the Andes.
04:26So, when one place is dry, the other one gives humidity and vice versa.
04:33I knew the snow a little bit.
04:35I knew where there was a hole,
04:38or a cave that ran like this,
04:41and I heard the noise of the water.
04:44Here we go, because there is a cave.
04:47Here we go, here we go.
04:48Here we go, from the other side, here we go.
04:50Here we go, but here we go.
04:54Here we go, until we go to the summit.
04:56So, from there we go to the university to know the snow.
05:02The study made us recognize that
05:06we needed a meteorological station to know more about the time.
05:11So, how are we going to do it?
05:13Do you have a place to make a station?
05:17Of course, I have it here in my house.
05:19If you want to connect with us to do those studies,
05:25then, if you like it, we will form it there.
05:30This station is approximately around 3.800 meters above the river.
05:35It is part of the high mountain.
05:38It is placed since the year 1974.
05:42And there begins the history of this station.
05:44Specifically, with Don Audoro.
05:48Don Audoro, who, from the 10th of June of 1974,
05:54started to be the observant volunteer,
05:57monitoring different variables,
06:01like precipitation, evaporation,
06:03extreme temperatures, medias,
06:06and the wind, mainly.
06:08And today we thank you,
06:10because it is the high mountain station with best records,
06:14and that shows how the temperature has ascended on our mountain.
06:21The station is at 3.700 meters,
06:25a little bit more,
06:27and the temperature register shows a curve here,
06:31always in constant ascension,
06:33thanks to this man who took the data every day.
06:38Those data had to be so exact.
06:417 in the morning,
06:43that we didn't pass 7 in the morning,
06:441 in the afternoon
06:46and 7 in the afternoon.
06:49And it is the station that we have today,
06:51that has more than 40 years,
06:53and it is working.
06:55That's why I have always been the one who was in front.
07:02For the health,
07:04because we are at 4.700 meters high,
07:08with that station,
07:09we can't live many years there
07:11because of the health,
07:15but for the rest,
07:17I'm interested in that station,
07:19because it has taken a lot of advantage
07:21so that I can help the humanity,
07:25people with those data that we have been able to give,
07:28the knowledge that I have.
07:32It was not until the 80s of the 80s of the past,
07:39when the glacier glacier earthquake was accelerated
07:43in the entire planet.
07:45It arrived in the 21st century
07:47and we had numbers of 3% to 5% of the area.
07:54The glaciers were reduced in Colombia.
07:57One year was a little more,
07:59another year was a little less.
08:02The glaciers began to fraccionarse more.
08:05The Sierra Neal Cocuy
08:06has stopped being a continuous sierra,
08:09they are divided in fragments
08:10every more small,
08:12they are subdividing,
08:14that exposes more to the atmosphere.
08:16It's very important to have data
08:21that show us the intensity of the climate change.
08:24The more long the data is,
08:27the better we have a knowledge
08:30of how this climate is behaved
08:32and where it goes.
08:34This station is unique
08:35because there is no other
08:36at that altitude with that register.
08:59they are headed against the gráficast speakers.
09:16The next station 길 decided to help
09:16What we did here was to show in the year 2022, in May 2022, where the edge of the snow
09:24came, which was here.
09:28Since 2022, we are in 2025, they have passed about two years, and we see that the glacier has been
09:37retroceded,
09:38more or less than 100 meters can be seen from this point to where the snow is.
09:45By the initiative of the IDEAM, the national parks also supported us,
09:50and private organizations such as the Cumbres Blancas.
09:55We with the community, with the initiative of them, the support to place this series of plates
10:05that are placed on the trails, which is an informative plate,
10:10where we show the glacier limit in a certain period of time, in this place.
10:20So, we put the year where the glacier was here, and the height of which we are with the glacier
10:28limit.
10:28So, it's basically for that, and to also leave a precedent of that here there was snow.
10:38After that, I don't want to say anything more, because there are reasons that I still go.
10:44Even with my years, I still go there, but with more difficulty.
10:49And I don't like to see how the nature of the snow, when I met it,
10:56it's the most precious, the most beautiful, and where all the mountains that have fallen,
11:02there are already soledad, there are already lands that don't give water,
11:10it doesn't have anything. That's why I'm full of nostalgia.
11:13I feel like that and look and lain as well,
11:17We just look at that, and of course we up just in the year and not the next spring sometimes.
11:23We'll be looking for it too.
11:24Today will be videos берies on爲明 and sorry.
11:34I'll be listening to other you guys soon.
