A new analysis by leading scientists claims that limiting global warming to 2 degrees Celsius, the target set by the Paris climate agreement, is now impossible. The study suggests that Earth's climate is more sensitive to rising greenhouse gas emissions than previously thought, and a decline in sunlight-blocking aerosols from shipping further exacerbates the crisis. The authors forecast temperatures to reach or exceed 1.5 degrees Celsius in the coming years, leading to devastating impacts on coral reefs and increasing the intensity of storms. By 2045, they predict warming will reach around 2.0 degrees Celsius. The findings have sparked debate within the scientific community, with some experts contesting the analysis and calling for caution.
Holding long-term global warming to two degrees Celsius – the fallback target of the Paris climate accord – is now"impossible," according to a stark though hotly debated new analysis published by leading scientists. Environment : Science and Policy for Sustainable Development
"That scenario is now impossible," said Hansen, formerly a top NASA climate scientist who famously announced to the US Congress in 1988 that global warming was underway, but had become an increasingly isolated voice in the scientific community.Instead, he and co-authors argued, the amount of greenhouse gases already pumped into the atmosphere by burning fossil fuels meant increased warming is now guaranteed.SD-Pictures/PixabayTemperatures will stay at or above 1.
The current brings warmth to various parts of the globe and also carries nutrients necessary to sustain ocean life. Scientists identified the threshold as critical to preventing the breakdown of major ocean circulation systems, the abrupt thawing of boreal permafrost, and the collapse of tropical coral reefs.

Ocean Warming Accelerates Fourfold, Fueling Urgent Need to Cut EmissionsA new study reveals that the rate of ocean warming has more than quadrupled in the last four decades, rising from 0.06 degrees Celsius per decade in the late 1980s to 0.27 degrees Celsius per decade currently. This accelerated warming, driven by Earth's growing energy imbalance due to increased greenhouse gas concentrations and reduced sunlight reflection, has led to record-breaking ocean temperatures. Scientists warn that this trend, if unmitigated, could further exacerbate global warming and its consequences.
