Pine Island Glacier is collapsing. A very negative scenario is expected for Pine Island, in the Arctic. Pine Island, the main Antarctic glacier, is thinning at a bewildering rate. The data shows that from 2017 to 2020 the glacier lost large icebergs from the edge, and the recent acceleration could lead to glacier collapse.
This is according to the study conducted by scientists from the University of Washington and the British Antarctic Survey, who evaluated satellite images obtained by the European Space Agency's Copernicus Sentinel-1 mission Pine Island Glacier contains approximately 180 trillion tons of ice, which could help raise sea levels by about half a meter on a global scale.
From 2017 to 2020, the platform lost a fifth of its total area. The authors of the study said that the acceleration has not yet reached potentially catastrophic levels, but there is a considerable risk that the situation will worsen in a short time.
Since 2017 the situation has worsened more and more, despite the fact that, according to geologists, the glacier has remained stable for thousands of years. Study authors said: "The Pine Island Ice Shelf is important because it helps retain some of the relatively unstable West Antarctic glacier if all buttresses in the rim were removed, the glacier could flow more rapidly to the ocean and contribute to raise the water level in a really significant way It seems that the glacier is tearing apart with an acceleration of 12%, due to the loss of the edge of the platform.
The processes we had studied in this region seemed to indicate an irreversible event but at a measured rate but now there is the possibility that these events will occur in a much more abrupt way."
Climate change is also affecting mental health
Climate change or climate change refers to variations in the Earth's climate, variations at different spatial and historical-temporal scales of one or more environmental and climatic parameters in their average values: temperatures, precipitation, cloudiness, ocean temperatures, distribution and development of plants and animals and buildings.
The various greenhouse gases play an important role in the climate since through the greenhouse effect they regulate the flow of energy retained in the earth's atmosphere and help to keep the climatic parameters constant by reacting in the phases of climate warming and cooling.
The predicted scenarios postulate that, as the planet warms, the polar ice caps melt and since snow has a high albedo. Global warming refers to the change in the earth's climate that has developed since the beginning of the 20th century and is still ongoing.
The scientific community attributes this change to emissions into the earth's atmosphere of increasing quantities of greenhouse gases and to other factors all attributable to human activity. Climate crisis is a term to describe human-induced global warming and climate change and their consequences.
The term has been used to describe the threat of global warming to the planet, and the need for aggressive mitigation of climate change. For example, an article published in January 2020 signed by more than eleven thousand scientists from 153 nations states that the climate crisis has arrived and that immense growth in efforts to preserve our biosphere is necessary to avoid untold suffering due to the climate crisis.
The Climate Change and Mental Health study, published on the Current environmental health reports, links the climate crisis, global warming and mental disorders. Here is an abstrac of the study: "A growing body of research demonstrates not only that the extreme weather events associated with a changing climate can impair mental health, in particular leading to increases in depression and post-traumatic stress disorder, but also that more gradual changes in climatic conditions, such as rising temperatures and reduced air quality, are also harmful to mental health.
In addition, there is increasing evidence that a significant proportion of people might be experiencing a harmful level of anxiety associated with their perception of climate change. Mental health impacts of climate change have the potential to affect a significant proportion of the population.
More research is needed to document the extent of these impacts as well as the best options for mitigating and treating them."
