Beware! Sea surface is warming

The cyclone Tauktee following Yaas unleashed a trail of devastation on the coastline of India last week. Though Yaas was not that much harmful, Tauktee brought a wave of devastation in coastal Maharashtra and Gujrat. The reason is obvious. According to scientists, the sea temperature is gradually increasing and now it has gone to above thirty-two degrees Celsius. Why the temperature on the sea surface is increasing can be easily understood. Global warming is also causing sea warming and which is causing frequent cyclones in its outer space. Already states on the coastline are grappling with Corona wave and now they will have to fight often with such cyclones. It is very hard to manage as already states, as well as center, has been out of resources. A week after Cyclone Tauktae wreaked havoc across the west coast of India, Cyclone Yaas made landfall in Odisha on the east coast on Wednesday. It then moved northwards and lay centered over northern coastal Odisha, but affected parts of Jharkhand and West Bengal. It did not harm much as Tauktee as Odisha and West Bengal administrations were vigilant enough. But the danger sign has been given by mother nature. Like Tauktae, Yaas also intensified rapidly. This, meteorologists and climate scientists said, can be linked to the climate crisis. Indian seas have been exceptionally warm, much warmer than usual, this year. Yaas and Tauktae were preceded by high sea surface temperatures reaching 31-32°C, making atmospheric and ocean conditions favorable for the frequent formation of cyclones and their rapid intensification. This phenomenon will be seen in the future and states will have to be alert every time. The economic damage these cyclones bring with themselves is another serious issue. This phenomenon, which will become a lot more frequent this century due to the climate crisis, will impact rainfall, cause destruction due to floods and gusty winds, and affect the scale and pace of the evacuation process needed to rescue lives. As our farming activity is mostly based on rainfall, this will have a very severe impact on our farm produce. The impact of the climate crisis on India is well-documented in scientific literature, and the spate of extreme weather conditions — heat/cold waves, floods, cyclones — that the country has witnessed in the last few years only confirms these warnings. India was the seventh most affected by the devastating impact of the climate crisis globally in 2019, according to the Global Climate Risk Index 2021. India must focus on nature-based solutions (for example, restoring mangroves to reduce the impact of waves and storm surge on the shoreline to prevent flooding and preserving wetlands, forests, and floodplains) to reduce disaster risk. It must also ensure that both existing and new infrastructure is climate-resilient. This means mainstreaming efforts to strengthen the resilience of urban systems by identifying disaster risks, enhancing structural resilience, and improve regulation and governance processes to manage risks. At the United Nations Climate Action Summit 2019, Prime Minister Narendra Modi announced a global Coalition for Disaster Resilient Infrastructure, a multi-stakeholder partnership of governments, UN agencies, multilateral banks, private sector, and knowledge institutions that aims to build resilience into infrastructure systems. This is a bold step in building resilience. But now, this has to proceed at a rapid pace. Year after year, month after month, week after week, and with every passing day, the climate crisis, in diverse forms, is extracting ever-increasing human, social and economic costs. As Tautake and Yaas have shown, both the State and citizens have to be prepared at all times. They may be prepared physically, but what about financial distress which will be common in near future. Mumbai is the country’s financial capital and its damage will be felt in the national economy.
