Den nyligt udkomne klimarapport fra FNs internationale klimapanel konkluderer, at Paris-aftalens klimamål om maksimal global opvarmning på 1,5°C bliver vanskelig at opnå. Ifølge rapporten er temperaturen nemlig allerede steget med 1,1°C siden den industrielle revolution.
Derudover konkluderer rapporten blandt andet:
- Human-caused climate change is already affecting many weather and climate extremes in every region across the globe.
- Continued greenhouse gas emissions will lead to increasing global warming, with the best estimate of reaching 1.5°C in the near term in considered scenarios and modelled pathways. Every increment of global warming will intensify multiple and concurrent hazards (high confidence). Deep, rapid, and sustained reductions in greenhouse gas emissions would lead to a discernible slowdown in global warming within around two decades, and also to discernible changes in atmospheric composition within a few years (high confidence).
- Limiting human-caused global warming requires net zero CO2 emissions. Cumulative carbon emissions until the time of reaching net-zero CO2 emissions and the level of greenhouse gas emission reductions this decade largely determine whether warming can be limited to 1.5°C or 2°C (high confidence). Projected CO2 emissions from existing fossil fuel infrastructure without additional abatement would exceed the remaining carbon budget for 1.5°C (50%) (high confidence).
