The progression of the climate crisis is revealing a range of negative phenomena around the world, from the melting of the poles to the increase in climate extremes. The rise of some of these processes, according to a study published this Friday in the scientific journal ‘One Earth’, accelerating and feeding back the progress of the climate crisis. Global warming, for example, increases the risk of fires worldwide. Every time a fire breaks out, the flames release large amounts of greenhouse gases into the atmosphere. This further increases the global increase in thermometers and exacerbates the scale of the climate crisis.
Experts have so far About 30 mechanisms that increase climate change have been identified. Biological processes such as forest return, soil carbon loss and wildfires are of particular concern. The progression of physical events, such as reduction in snow cover, increase in Antarctic precipitation, and reduction of the planet’s ice reserves, is also alarming.
The other side of solving
One of the most obvious examples of this phenomenon is warming in the Arctic, according to the analysis published this Friday. Rising temperatures in the Arctic melting the planet’s sea ice and causing the waters to warm. Due to these phenomena, The sea absorbs the sun’s rays instead of reflecting them.. All this increases the rise in temperatures in the region and in turn accelerates the melting process in the Arctic.
The same goes for thawing permafrost: this was the “eternally frozen soil” found in the coldest parts of the planet until now. The climate crisis triggers accelerated loss of this ice expanse in these regions. This process is an important increased emissions of carbon dioxide and methane into the atmosphere, which further accelerates the global rise in temperatures on the planet.
turning point
Experts warn that this kind of dynamic could worsen forecasts for the progression of the world’s climate crisis. “Current climate models may be underestimating the global rise in temperatures because they do not account for this increased array of feedback loops.”said Christopher Wolf, one of the scientists who spearheaded this analysis.
Another aspect that worries experts most is how these mechanisms bring the ‘tipping points’ of the climate crisis closer. “Some of these climate feedback loops are associated with multiple tipping points, which will make trying to reverse their effects even more difficult.” highlights researcher Jillian Gregg, co-author of this analysis and an expert on the Terrestrial Ecosystems Research Associates platform.
call to action
Based on these results, the panel of experts leading this analysis launched a new call to action. “Reduce greenhouse gas emissions immediately”. “Transformative and socially just changes are needed to meet the challenges of the climate crisis in sectors such as global energy and transportation, air pollution, food production, nature conservation and the international economy,” emphasizes William Ripple of the University of Oregon. , another of the experts who led this study.
The scientific community also calls for more research efforts to understand exactly how these phenomena progress, and in turn, improve the formulation of more effective public policies to address the effects of the climate crisis around the world.
