The world is heading towards an increase of 3 degrees Celsius due to the slow decline in the use of coal for energy production. Climate change represents a global emergency that requires concerted efforts from all countries of the world to reduce and control it, and this is the main axis around which the Paris Climate Agreement revolved, as 197 countries adopted the Paris Agreement at a conference in the French capital on December 12, 2015, which entered into force Implementation after less than a year. This agreement aims to significantly reduce global greenhouse gas emissions, limiting the global temperature increase in this century to 2 degrees Celsius while seeking to limit the increase to 1.5 degrees. higher warming But according to a recent study, it seems that achieving the goal of keeping the temperature rise within only 2 degrees Celsius has become difficult, and that the world is heading towards an increase of 2.5 to 3 degrees Celsius. The main reason for this is that reducing the use of coal in industry and power generation is not moving fast enough, although there is potential to do so. Coal phase-out must be faster (Getty Images) The research , published in the journal Environmental Research Letters, by a group of scientists from Chalmers Universities of Technology and Lund in Sweden, indicates that the historical experience of individual countries indicates feasible rates of coal phase-out. “More countries are promising that they will phase out coal from their energy systems, which is something Positive. But, unfortunately, its commitments are not strong enough." "If we have a realistic chance of achieving the 2-degree target, the phase-out of coal needs to be faster," he says. India and China To arrive at their findings, the researchers analyzed the commitments made by 72 countries to phase out coal use by 2022-2050. The results show that (in the best case scenario) the increase in temperature could stop within 2 degrees, but this assumes – among other things – that China and India begin to phase out their use of coal within 5 years, as it should be. Phase-out is as rapid as it was in the UK, the fastest it has ever happened in a large country and faster than Germany promised. In both China and India, it is assumed that the phase-out of coal use will begin within 5 years (Shutterstock) The press release also states that the researchers have put together the scenarios they consider to be more realistic, which indicate that the Earth is heading for a global warming of 2.5 to 3 degrees. Jessica Jewell, associate professor in the Department of Material Resource Theory at Chalmers University of Technology, says states' commitments – including ambitious ones – are not enough. She adds that Russia's war on Ukraine may prevent some countries from phasing out coal as promised. Fears of imbalance The study shows that the commitments of 72 countries to phase out coal power are similar to each other, and is consistent with historical data for how quickly coal power phase out has gone in the past. While some of these pledges have strengthened over time, the energy crisis caused by the Russia-Ukraine war has weakened up to 10% of these pledges. The research finds that more ambitious coal phase-out scenarios require much stronger efforts in Asia than in OECD countries, and this raises equity concerns that must be addressed through international policies.

New research has concluded that global warming is on track for a 2.5-3°C increase, contrary to what the Paris climate agreement aspired to, because of the slow decline in the use of coal for energy production.
