00:00:00 - 00:20:00

The video discusses the importance of climate change and glaciation, and highlights the need for individuals to take action in order to protect the environment. Glaciation is a natural process that is accelerated by human activity, and therefore, it is important to protect the glaciers in order to preserve both the water supply and the environment surrounding them. Individual action is crucial in order to reduce climate change and avert its worst consequences.

• 00:00:00 The video discusses the effects of climate change on glaciers, and how they are melting due to global warming. Glaciers are shrinking and may disappear in the near future, due to the effects of climate change. This can have serious consequences for the environment, including the extinction of species. However, humans have made great progress over the years, and are still able to advance in many fields thanks to the energy we receive from the sun. Atmosphere allows solar radiation to enter, which warms the Earth and emits heat in the form of infrared radiation. This prevents the escape of all the heat into space and it is returned to the planet by the Earth's atmosphere. This phenomenon, called "invernadero," is what allows us to exist on Earth. It's one of the many consequences of climate change, and it's been happening faster in the last 100 years due to the increase in temperatures. Glaciers are retreating even in some cases and have disappeared in the past. Glaciers store water in winter in the form of snow, and release it in summer during the melting. This makes them a vital source of water for many regions of the world. A glacier is a mass of ice in motion, with its component parts starting at the head where it births the glacier
• 00:05:00 This video discusses the impact of climate change on the glaciers in the Patagonian region, which is experiencing a dramatic retreat due to global warming. Glaciers in the region are classified according to their activity (active, passive, or dead), and the overall trend of retreat is clear. The melting of the ice has also caused the sea level to rise, which has in turn affected coastal communities.
• 00:10:00 The importance of glaciers is based on their relationship with global climate, water reserves, and the rise in sea levels around the world. Climate change has a significant impact on hydrology and hydrogeology in Antarctica, which is why it is important to understand the behavior of water in ice form, as seen in this video. Changes in water distribution within glaciers lead to modifications in water flow within the same watersheds, as well as an increase in the amount of water carried by rivers, which leads to increased sedimentation and ultimately to the ocean. Antarctic ice is also important because, as humans quickly realize, 97% of the world's freshwater is contained within the continent's ice, making it a vital strategic reserve. Climate change is the result of a complex combination of global factors, though some impacts are not yet reversible. It is important to take action to mitigate certain effects through international legislation, political policies, and individual actions. With rapid glacier retreat occurring in multiple areas of the continent, Argentinian scientists monitoring the Furcal Glacier have noted a decrease in mass over the past few decades, and they anticipate even more serious shrinkage in the future as a consequence of global warming.
• 00:15:00 The effects of climate change are being felt all around the world, including in Argentina. One of the most important climatic changes happening right now is the shrinking of glaciers. One glacier in particular, the Upsala Glacier, is retreating quickly and is expected to have a significant impact on the province of Santa Cruz. To combat the effects of climate change, individuals and communities need to be aware and take action. One way to do this is to understand and use alternative energy sources.
