[^1]\n\nThe United Nations Environment Programme (UNEP) released a new report warning that global temperatures will exceed the 1.5°C limit established in the 2015 Paris Agreement in the coming years. [^2]\n\nThe Earth is set to exceed the safe temperature threshold agreed upon in the 2015 Paris Climate Pact due to heating caused by burning coal, oil, and gas. [^3]\n\nThe United Nations has acknowledged that the Earth has lost the opportunity to avoid the worst damages of global warming. [^4]\n\nMost scenarios other than the best-case predict that global temperatures will rise beyond 2.0 degrees before peaking. [^5]\n\nThe report indicates that crossing the 1.5-degree threshold increases the risk of climate tipping points where the climate runs away with catastrophic consequences. [^6]\n\nResearchers warn that a warming of up to 3°C above pre-industrial levels would be devastating, potentially causing the loss of more than a quarter of glacier mass by 2100. [^7]\n\nThe report calls for immediate and sustained reductions in greenhouse gas emissions, specifically highlighting the need to address methane emissions. [^8]\n\nA new strategy recommends limiting excessive warming and then lowering temperatures back below the agreed threshold by ending fossil fuel use and developing methods to extract carbon dioxide from the air. [^9]\n\nAntónio Guterres, the UN Secretary-General, stated that humanity is speeding past the limit to avoid a climate catastrophe.
