Amidst the global turmoil, the Intergovernmental Panel on Climate Change – the largest international consortium of scientists analyzing and reviewing evidence on the current and future man-made impacts of climate change – has a message that is predictably grim. With a global warming of 1.5°C the world faces several climate threats inevitable in the next two decades; Even temporarily exceeding this warming level would mean additional serious effects, some of which would be irreversible. The report suggests that the increase in weather and climate extremes has led to some irreversible impacts as natural and human systems are pushed beyond their ability to adapt. Referring to the Conference of the Parties (COP26) in Glasgow in November 2021, the report noted that most of the targets that countries have set for themselves are intended to make a short-term impact on meaningfully mitigating the climate in the future. are too far away. Effect.
India will achieve net zero emissions by 2070, i.e. no net carbon emissions, Prime Minister Narendra Modi announced at the COP26 summit. By 2030, India will also ensure that 50% of its energy will come from renewable energy sources. However, none of this can help keep the 1.5°C mark from cracking. A key point of the report, particularly for South Asia, is the trend in ‘wet bulb’ temperature – an index of the combined effect of heat and humidity – and its impact on health. Lucknow and Patna, according to one of several studies cited in the report, were predicted to reach wet-bulb temperatures of 35 °C in those cities if emissions continued to rise, while Bhubaneswar, Chennai, Mumbai, Indore And Ahmedabad is ‘on’. Risk of reaching wet-bulb temperatures of 32 °C–34 °C with continued emissions’. This would have consequences such as an increase in heat-wave-related deaths or a decrease in productivity. Global sea level will rise 44cm-76cm this century if governments meet their current emissions-cutting promises. But with higher emissions, and if ice sheets fall faster than expected, sea levels could rise by 2 meters this century and 5 meters by 2150. India is one of the most vulnerable countries in terms of population which will be affected by the sea. – Level increase. By the middle of the century, about 35 million of its people may face annual coastal flooding, with 45 million–50 million at risk by the end of the century if emissions are higher. Experience has shown that biased economic calculations beat climate considerations, but India must ramp up its adaptation measures and take immediate steps to secure the future of its many vulnerable people who have the most to lose. Is.
