According to researchers from the Meteorological Office in London, the temperature of our planet in the year that is about to begin will probably be between 0.91 and 15 degrees Celsius higher than it was in the period 1850-1900, with an average estimate of 1,03 degrees more.
But this year things could differently: this is because La Niña will influence the temperature in 2021, for an year which will anyway be among the warmest ever. La Niña amplifies the normal oceanic and atmospheric circulation conditions.
The impact of natural cooling phenomena such as La Niña are largely overshadowed by the warming of the atmosphere caused by the greenhouse effect, or by the emissions of harmful gases that are at the root of climate change.
But temperatures will just be slightly below the temperature of 2020. This causes colder water to rise to the surface from the depths of the ocean. This is expected to reduce sea surface temperatures by 1-2 degrees, preventing 2021 from setting a new record for global warming.
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."
