Indian Ocean warming rapidly, expect more extreme weather
IPCC report on climate change warns of more cyclonic activity, rainfall The latest report by the Intergovernmental Panel on Climate Change today confirmed fears that the Indian Ocean was warming at a rate higher than other oceans. According to the authors of the IPCC’s Sixth Assessment Report (AR6), “Climate Change 2021: The Physical Science Basis”, the warming of the ocean will lead to a rise in sea levels, resulting in more frequent and severe coastal flooding in low-level areas. Impact irreversible Scientists caution that impacts of climate change-triggered glacial retreat, sea-level rise, and intense tropical cyclones, erratic monsoon and intense heat stress are irreversible Hot extremes projected to increase, cold extremes to decrease in the 21st century Sea surface temperatures over Indian Ocean are likely to increase by 1 to 2°C Heatwaves and humid heat stress will also be more intense and frequent in the 21st century over South Asia, states the report, sounding a dire warning for the entire world. “Even if we limit temperatures to 1.5° Celsius from pre-industrial levels, we will continue to see extreme weather events,” said Dr Friederike Otto, one of the authors. “We will also see an increase in heatwaves, heavy rainfall events, and the further melting of glaciers, which will impact a country like India,” said Otto. Warning for developed nations Report a clarion call for developed countries to undertake immediate, deep emission cuts and decarbonisation of their economies. — Bhupender Yadav, Environment Minister It’s a wake-up call The latest IPCC report confirms we can no longer lose time in prevarication or in finding new excuses not to act. — Sunita Narain, Centre for Science and Environment Director General
