Scientists believe the world could pass through several catastrophic tipping points, from melting ice caps to drying up rainforests.
According to a United Nations analysis released Monday, current emissions of countries commit to limiting climate change would cause global warming of nearly 3 degrees Celsius this century .
The annual emissions gap report, which assesses countries’ pledges to combat climate change against what is needed concludes that The world will face warming of between 2.5°C and 2.9°C above pre-industrial levels if governments do not step up climate action .
With heating at 3ºC scientists predict that The world could pass through several catastrophic tipping points Since the melting of the ice caps until the drying out of the Amazon rainforest .
“Current trends are leading our planet into a 3°C temperature rise impasse “, declared UN Secretary-General Antonio Guterres.
“The emissions gap is more of an emissions canyon “he added.
World leaders will soon gather in Dubai for the annual UN climate summit COP28 with the aim of maintain the 1.5°C warming target of the Paris Agreement .
However, the new report gives no hope that this objective remains within reach , since it concludes that greenhouse gas emissions that warm the planet must be reduced by 42% by 2030 to keep warming at 1.5ºC .
Even in the most optimistic emissions scenario, the chance of limiting warming to 1.5°C is just 14%, adding to a growing body of scientific evidence suggesting the target is dead .
Global greenhouse gas emissions increased by 1.2% between 2021 and 2022 reaching a record 57.4 gigatons of carbon dioxide equivalent.
