According to the IPCC, humanity has three years to reduce its CO2 emissions

According to scientists, humanity has only three years left to take action to keep the world “livable”. Humanity has less than three years to reverse the curve of greenhouse gas emissions, the main culprits of climate change, if it wants to maintain a “liveable” world, UN climate experts warn on Monday in a new report. The most ambitious goal of the Paris Agreement to limit warming to +1.5°C compared to the pre-industrial era is “out of reach” with current international commitments, underline the IPCC experts. And even if ‘peak emissions’ are indeed reached before 2025 and ‘immediate actions’ are taken, warming could reach 2°C.”We are at a turning point. Our decisions today can ensure a livable future “, insists the boss of the IPCC, Hoesung Lee. climate change, underline the UN climate experts (Giec). Among these 10% of the wealthiest, two thirds live in developed countries. Emissions related to the lifestyle of the middle and underprivileged classes in developed countries are 5 to 50 times higher than those of their counterparts in developing countries, also indicates the IPCC. untapped”Acting on the demand for energy and the consumption of goods and services would make it possible to reduce greenhouse gas emissions responsible for climate change by 40 to 70% by 2050, experts estimate.”Disposing of public policies , infrastructure and technology to enable changes in our lifestyles and behaviors (…) offers significant untapped (reduction) potential,” said Priyadarshi Shukla, one of the co-chairs of the IPCC working group. on solutions to reduce the causes of climate change. A third partIn the first part of its report published in August 2021, the IPCC pointed to the acceleration of global warming, predicted knowing that the threshold of +1.5°C compared to the pre-industrial era could already be reached around 2030. The second, at the end of February, painted a more than gloomy picture of the past, present and future impacts on the population and the ecosystems, emphasizing that delaying action reduced the chances of a “livable future”.>> To read also: “‘Irreversible’ impacts: the IPCC warns of the effects of climate change” madness”UN Secretary General Antonio Guterres had been more than clear on the opening day of the talks of the 195 member states of the IPCC two weeks ago: the dependence on oil, coal and gas is a “madness”. “We are walking with our eyes closed towards climate catastrophe” and “if we continue like this, we can say goodbye to the 1.5°C target. That of 2°C could also be out of reach”, he insisted, referring to the objectives of the Paris agreement. After more than a century and a half of development based on fossil fuels, the planet has gained around +1.1°C on average compared to the pre-industrial era, already favoring the multiplication of heat waves, droughts, storms or devastating floods.
