<p>Tropical cyclone Dana made landfall on the intervening nights of Thursday (Oct 24) and Friday (Oct 25) between Bhitarkanika and Dhamra coasts in India's Odisha, and the process continued till 7:00 am (local time) on Friday.&nbsp;</p>

<p>Pointing to the reasons behind the high frequency and intensity of cyclones across the world, Pushpendra Johari, senior vice president of sustainability&nbsp;at RMSI,&nbsp;a global geographic information system&nbsp;(GIS) consulting company, told WION that it is all because of climate change, adding that now the oceans are much warmer than it used to be before, which is causing more such events.&nbsp;</p>

<p>Johari recalled the last two Hurricanes, Helene and Milton, that hit the US state of&nbsp;Florida in the past two months.&nbsp;</p>

<p>"This is all happening because of climate change. The oceans are much more warmer than they used to be and that is why more such events are happening. Moreover, it is not just happening in the Indian oceans, but there have been two hurricanes in a very short span of time in the Atlantic, that is hurricanes Helene and Milton. It is happening across the globe, wherever the ocean water is warming, it is causing more events," he said.&nbsp;</p>

<p>Shifting to the cyclone situation in India, Johari&nbsp;said &nbsp;"The Bay of Bengal has had more cyclone events but the frequency has now increased a little bit. There was a time when the average was about two to three events per year, but it is increasing now."&nbsp;</p>

<h2><strong>Cyclone Dana&nbsp;</strong></h2>

<p>Cyclone Dana made landfall in Odisha early Friday, leading to heavy rainfall and strong winds across coastal regions. Initially, it came with a speed of 110 kmph.&nbsp;However, later, it weakened to a cyclonic storm, according to the India Meteorological Department (IMD).</p>

<p>The IMD reported that Cyclone Dana, after making landfall, is likely to continue moving northwest across north Odisha, weakening into a deep depression over the next six hours.</p>

<h2><strong>Cyclone's impact in Odisha</strong></h2>

<p>The IMD has further issued a red alert for a few districts including, Bhadrak, Balasore, Keonjhar, and Mayurbhanj districts, expecting continued downpours through Saturday (Oct 26)&nbsp;morning.&nbsp;</p>

<p>So far, over 500,000 people have been evacuated&nbsp;to shelters, according to&nbsp;Odisha Chief Minister Mohan Charan Majhi. The state is making extensive preparations to tackle the cyclone by setting up 5209 cyclone shelters.&nbsp;</p>

<p>Moreover, the Highest Education Minister Suryabanshi Suraj said that there has been power disturbance, house damage and agricultural land has also been affected.</p>

<h2><strong>Cyclone's impact in Kolkata&nbsp;</strong></h2>

<p>One person has died in the Indian city of Kolkata in the aftermath of a cyclone, West Bengal Chief Minister Mamata Banerjee said.&nbsp;</p>

<p>Kolkata has evacuated approximately 200,000 people from low-lying areas.&nbsp;</p>

<p>"Only one person died in this natural disaster. The man died at his residence while conducting some cable-related work. It is quite unfortunate. The postmortem examination will give us a clear picture. If required we (the state government) will help the family," said Banerjee.&nbsp;</p>

<h2><strong>'Bulk impact in Odisha'</strong></h2>

<p>RMSI Senior VP&nbsp;Johari&nbsp;further highlighted the impact of cyclone Dana in Odisha and West Bengal.&nbsp;</p>

<p>"Bulk impact is going to be there in Odisha. Our estimate is that the impact would be somewhere about 3,000 million of damage, in terms of infra, buildings and everything in Odisha," he said.&nbsp;</p>

<p>Referring to the condition in West Bengal, he said that the least impact of the cyclone would be in West Bengal as it lies on the outer band.&nbsp;</p>

<p>"If we look at WB, its trajectory is still such that, there will be winds in West Bengal. Only the least impact band is going to be there. There is going to be a lot of rain, there could be potential for floods but as far as the impact of wind is considered, it won't have much impact," he said.&nbsp;</p>

<p>Johari&nbsp;continued, "However, the impact could come in form of a flood. Odisha will experience 110 kmph, and West Bengal may experience 80 kmph as it is on the outer band."&nbsp;</p>

<p>Further, there is going to be a decent impact on electricity, according to RMSI estimates, Johari said.&nbsp;</p>

<p>"There is going to be a lot of tree fall as a result of that, many polls can also get uprooted, which could lead to electric power disruption in a lot of ways," he added.&nbsp;</p>

Cyclone Dana: What's causing high frequency of massive storms across globe?

<p>Key infrastructure in Indian coastal cities may submerge by 2050 as per a new analysis by RMSI, a global risk management firm. These cities include Mumbai, Chennai, Kochi, Vishakhapatnam, Thiruvanathapuram, and Mangalore.</p>

<p>Haji Ali mosque, Jawaharlal Nehru Port Trust, Western Expressway, Bandra-Worli Sea-link, and Queen's necklace on Marine Drive are the critical properties and road networks that are facing the risk of submergence in Mumbai alone.</p>

<p>The findings of the analysis have been published in the report titled ''Climate Change 2021: The Physical Science Basis.''</p>

<p>Experts at RMSI used a coastal flood model to map the inundations levels based on various sea-level rise forecasts after creating a high-resolution digital terrain model (topography).</p>

<p>Earlier, the UN's Intergovernmental Panel on Climate Change (IPCC) had predicted a significant level of sea-rise in India. Meanwhile, a report by the Ministry of Earth Sciences (MoES) the north Indian Ocean will rise by approximately 300 mm (a foot).</p>

<p>According to Roxy Mathew Koll, climate scientist, Indian Institute of Tropical Meteorology, ''While we talk about sea-level rise, that is not the only factor that can inundate coastal cities. At 1°C global change, coastal regions are already facing the brunt of climate change with increasing intense cyclones, storm surges, and heavy rainfall events that lead to coastal flooding.''</p>

<p>&nbsp;''While cyclones on the west coast have increased by 52 per cent&nbsp;over the last four decades, extreme rains causing floods have seen a threefold rise since the 1950s. By 2050, the global temperature change will be close to 2°C, and these cyclones and heavy rains are projected to intensify further, putting the coastal cities in danger.''</p>

<p>''The accelerated sea-level rise can compound coastal flooding due to these events, raising the water level and resulting in floods that cover larger areas for longer times. We need to urgently monitor and study these compound events (where multiple extremes overlap) so that we can prepare our early warning systems for efficient disaster management,'' he added.</p>

<p>Pushpendra Johari, senior VP, Sustainability, RMSI Pvt Ltd said, ''How much water will go inland is a function of what kind of continental shelf we have. The impact of sea level rise will be different in different parts. No client asked us to do these modelling studies. Because the IPCC report suggested Indian coastal cities could be in danger, we felt we should quantify these findings.''</p>

<p>''We intend to reach out to affected state governments and we will definitely share the findings with the World Bank and National Disaster Management Authority.''</p>

<p>“We considered RCP 4.5 which is an intermediate scenario. Sea level is expected to rose at least 2050 and then stabilise,” he added.</p>
