IPCC sixth report predicts more intense heat waves and heavier rainfall for India
The Intergovernmental Panel on Climate Change (IPCC) has released its sixth assessment report titled 'Climate Change 2021: The Physical Science Basis'.
<p>The report shows that <a href="https://theprint.in/environment/india-to-suffer-more-intense-heat-waves-heavier-rainfall-in-future-decades-ipcc-report-says/711949/" >India will experience more intense heat waves and increased precipitation</a> during the rest of the 21st century. Furthermore, the report warns that <a href="https://www.indiatoday.in/science/story/ipcc-climate-report-coastal-cities-in-india-sea-level-rise-environment-global-warming-indian-ocean-1839061-2021-08-10" >12 Indian coastal cities could become nearly three feet under water</a> by the end of the century due to climate change. In the Asian region, heat extremes have gone up while cold extremes have gone down, and both trends are expected to continue. </p>
In the global context, the report finds that climate change is having a significant impact on every region of the planet. Over the next 20 years, the global temperature will reach or exceed 1.5°C of warming, predicts the report. (The Print, India Today)
