Recent research from the University of Geneva Discover Temperatures are moderately high Land It could lead to “uncontrolled global warming” with irreversible consequences, leading the planet into a state of unlivability similar to that of Venus.
The analysis, which included collaboration with specialists from the French National Center for Scientific Research (CNRS), was based on 3D models of the simulated planets. With the final data, scientists Discover The gap between a habitable planet and one where life is unsustainable is surprisingly narrow, at just a few degrees.
The simulation developed by the researchers produced a planet similar to ours LandAnd equipped with oceans and life forms. In this model, a temperature increase of just a few tens of degrees was enough to trigger a chain reaction, radically and rapidly changing the planet’s conditions, as detailed in the Swiss university’s statement.
The professor from the Department of Science and Technology explained that “the evaporation of just 10 centimeters on the ocean surface will lead to an increase in atmospheric pressure by one bar, and in just a few hundred years a surface temperature of 500 degrees will be reached.” Astronomy at the University Guillaume Chaverot, leader Stady.
According to the report issued by the University of Geneva, the evolutionary process of climate change could lead to… Land Experience atmospheric pressures of up to 273 bar and temperatures close to 1,500 degrees. In this extreme scenario, the planet’s oceans would evaporate completely, says one of the experts involved in the project. Stady.
Research published in the magazine Astronomy and astrophysics, aims to deepen understanding of the “runaway greenhouse effect” (or “runaway greenhouse effect” in English). Unlike studies Previous work focused on the earlier or later stages, this work focuses on the process itself.
The University of Geneva stressed that this extreme greenhouse effect could turn a planet that was previously ideal for life into an inhospitable one. The research explores the possibility of a radical increase in temperature, linked to a future increase in the intensity of sunlight. However, scientists are also considering whether the effects would be similar if the increase in temperature was caused by other factors, such as an increase in carbon dioxide. And other greenhouse gases.
It is important to note that global warming, properly measured, is essential for life in the world Land. For example, experts cite water vapor, which contributes to moderate and necessary global warming. Without this phenomenon, the planet’s average temperature would drop below the freezing point of water, making life as we know it impossible.
