Water Scarcity, Sea Level Rise, Intensified Floods, Droughts, Heat Waves

Climate change is proving its presence worldwide through increased extreme weather events such as floods, droughts, landslides, excessive rain, heat waves, and sea level rise. To say that “climate change is real” would be an understatement, and denying the phenomenon would only lead to catastrophic occurrences. In the last two decades, India witnessed a shift in its climate patterns in the form of changes during summer, monsoon, and winter seasons. The country experienced unprecedented heat waves in recent decades.  In 2023, India received unseasonal rainfall in the pre-monsoon period. El Niño conditions emerged in May.  In early July, excess rainfall occurred in Delhi and the National Capital Region, causing Yamuna to breach the 1978 level that resulted in catastrophic floods. Surprisingly, the eastern parts of the country received less rainfall than other regions this year, which is unusual because eastern and northeastern states are known to receive ample rainfall in monsoon. July 2023 was found to be the hottest month in over 1,20,000 years. The heat island effect has become more pronounced in urban areas. Also, agriculture is impacted both in the long term and short term, due to climate change.

For instance, due to personal risk factors such as age, poor ventilation, and cooled housing, occupational risk factors such as working outdoors, and societal risk factors such as urban planning, some workers are disproportionately affected by the impacts of extreme heat. The negative impacts on productivity and health can be reduced through well-designed and effectively implemented heat action plans.  MUST READ | <a title="Why Did Eastern Parts Of India Receive Less Rainfall Than Other Regions This Year?

As India celebrates its 77th year of independence, ABP Live spoke to Dr Roxy Mathew Koll, Climate Scientist at the Indian Institute of Tropical Meteorology and Lead IPCC Author; Prof Anamika Barua, Department of Humanities and Social Sciences,IIT Guwahati, and Dr Anjal Prakash, Clinical Associate Professor (Research) and Research Director, Bharti Institute of Public Policy, Indian School of Business, and asked them what climate threats lie ahead for India.  More frequent and severe extreme weather events, water scarcity, sea level rise, increased cyclonic activity, and landslides are some of the impacts of climate change India is likely to witness by the next decade, the experts said. If appropriate mitigation strategies are not adopted, the damage may be irreversible.  MUST READ | EXCLUSIVE: <a title="Women Make Up 16 Per Cent Of Indian Scientists, This Is Quite Low: Experts On Status Of Women Scientists Since Independence" href="https://ift.tt/WrLtVbo" target="_self">Women Make Up 16 Per Cent Of Indian Scientists, This Is Quite Low: Experts On Status Of Women Scientists Since Independence</a> The Intergovernmental Panel on Climate Change’s (IPCC’s) Sixth Assessment Report (AR6) mentions that anthropogenic activities will exacerbate climate change. What is even more serious is the fact that climate change will disproportionately affect people, and vulnerable communities are the ones who will suffer the greatest losses.  “Predicting the exact impact of climate change over the next 10 years is challenging due to the complexity of the Earth's climate system and the wide range of factors involved. But one should refer to the IPCC AR 6 report, released in 2022, which clearly explains that anthropogenic climate change will impact all sections. Some indications are extreme events such as floods, droughts, heat waves, and sea level rise, among others. The intensity and frequency of these events will increase and may lead to irreversible damage. Unfortunately, the impact will be disproportionate, affecting mostly vulnerable communities worldwide. This indicates that the developing world will most feel the impact, so we must prepare well,” Dr Barua said.  MUST READ | EXCLUSIVE: <a title="Brain Drain', Indigenous Equipment Development — Challenges For India In Science, And What Experts Suggest To Overcome Them" href="https://ift.tt/FNTkfzx" target="_self">'Brain Drain', Indigenous Equipment Development — Challenges For India In Science, And What Experts Suggest To Overcome Them</a> Due to the shift in weather patterns during the last two decades in India, sea levels have risen, glaciers are melting at an increasing rate, and monsoon has become varied, with long dry spells or incessant rain that leads to floods. Also, Arabian sea cyclones have increased. The reason why these extreme weather events occurred is the rise in global temperatures by one degree Celsius due to carbon emissions.  “During the last two decades, we saw a clear climate shift in the weather patterns over India, resulting in rising sea level, cyclones, floods, landslides, glacier melt, heatwaves (on land and in the ocean), and droughts. Monsoon rainfall patterns have changed, from rains spread moderately through the season to long dry periods and heavy rainfall events that cause floods. Arabian Sea cyclones have increased by 50 percent, while their lifespan has increased by 80 percent. The steadfast rise in these severe weather extremes is in response to the 1°C rise in global temperatures due to historical carbon emissions,” Dr Mathew Koll explained.

This is because the commitments from global nations are insufficient to keep the temperature rise from hitting 1.5°C by 2040 and 2°C between 2040–2060.” One of the areas at the highest risk of climate change calamities are coastal regions. These devastating repercussions can displace communities such as fishermen who live in coastal areas, and affect their livelihoods.  ALSO READ | <a title="Why Is The Invention Of The Atomic Bomb A Quintessence Of Scientific Triumph?

It 'Accelerated' Science, Say Experts</a> “Climate change's impact on India in the coming years could be profound. Projections suggest increasing temperatures, erratic rainfall, and more frequent extreme weather events. Coastal regions are at risk due to rising sea levels, potentially displacing communities. Water scarcity may intensify due to changing precipitation patterns. Heatwaves and droughts could become more severe, impacting agriculture and water resources. While specific climate calamities in the next 10 years are hard to predict precisely, increased cyclonic activity, flooding, and landslides are potential threats,” Dr Prakash said. Apart from mitigation measures, adaptive strategies must be enforced, and resilient infrastructure developed to ensure that India is prepared for potential climate change calamities, and can minimise risks of catastrophic impacts.
