Cyclone warning systems more accurate now: MoES
New Delhi: Cyclone warning systems have become substantially more accurate, with improvements of up to 65 per cent in landfall prediction within 48 hours, a senior official on Monday said. Addressing a press conference on 11 years of the Modi government, Ministry of Earth Sciences (MoES) Secretary Dr M. Ravichandran said forecasts of other severe weather events such as heavy rainfall, fog, and heatwaves have improved by 40 per cent over the last five years. Monsoon forecasting has also seen a major shift, moving from statistical to physics-based models under the National Monsoon Mission, significantly enhancing the accuracy and spatial resolution of seasonal predictions. 'These improvements are the result of sustained investments in research infrastructure and technology over the past decade,' said Dr Ravichandran, while outlining the ministry's key achievements from 2014 to 2025. Among the major milestones highlighted was the launch of the Bharat Forecast System in May 2025, a high-resolution (6 km) global weather model aimed at strengthening India's capability in weather prediction. In September 2024, the government also rolled out 'Mission Mausam', a nationwide initiative to make India 'weather ready and climate smart'. India's first Earth System Model (IITM-ESM) played a key role in international climate science, contributing to the Intergovernmental Panel on Climate Change's Sixth Assessment Report (IPCC AR6) and the Coupled Model Intercomparison Project Phase 6 (CMIP6), he said. In ocean science, the Deep Ocean Mission marked a turning point with successful wet harbour trials of Matsya-6000, India's manned submersible capable of reaching 6,000 metres below sea level. Dr Ravichandran said this will pave the way for deep-sea exploration and sustainable extraction of marine resources. 'We have also discovered two active and two inactive hydrothermal vents in the Indian Ocean and identified 23 new species in biodiversity surveys --strengthening India's position in ocean science,' he added. The Ministry also released an Integrated Ocean Energy Atlas to assess renewable energy potential, estimated at 9.2 lakh TWh annually, from India's Exclusive Economic Zone (EEZ), including wave, tidal, wind and ocean thermal energy. Services for the fishing and maritime community have expanded considerably, with over seven lakh fishermen now receiving Potential Fishing Zone (PFZ) advisories, up from one lakh in 2014. Marine services such as oil spill alerts, coral bleaching forecasts and harmful algal bloom warnings now reach nearly 9.45 lakh stakeholders across India and in six other Indian Ocean countries, the official said. India's tsunami alert capabilities have also advanced, he added. 'Earlier, we were limited to Indian Ocean events, but now we can issue tsunami warnings within 10 minutes for any global ocean earthquake. These alerts are shared with 25 Indian Ocean Rim countries,' said Dr Ravichandran. In polar science, India continues to operate two Antarctic research stations and one in the Arctic, supporting over 100 scientists annually. The passage of the Antarctic Bill in 2022 and the release of the Indian Arctic Policy the same year further strengthened India's scientific and diplomatic presence in polar regions, he said. Domestically, the National Seismological Network now comprises 166 observatories, up from 86 in 2014, enabling the detection of earthquakes of magnitude 3.0 and above, he said. Eight Indian cities have undergone seismic microzonation to improve earthquake-resilient infrastructure, he said. A three-km deep borehole in Maharashtra's Koyna region is being studied to understand reservoir-triggered quakes. The MoES official said the ministry has also implemented thermal desalination in Lakshadweep, improving access to potable water and reducing water-borne illnesses. Coastal restoration projects in Puducherry and Tamil Nadu have reclaimed eroded beaches using innovative engineering solutions. To make scientific services more accessible, the ministry has launched several public-facing mobile apps -- Mausam, Meghdoot, Damini, SAFAR AIR, and Bhookamp -- and digital platforms like the Earth System Science Data Portal and Digital Ocean.

Oil spill from fire-damaged container ship may reach Kerala coast by June 14
THIRUVANANTHAPURAM: The Indian National Centre for Ocean Information Services (INCOIS) has warned the state government that the oil spill from the fire-damaged cargo vessel Wan Hai 503 could reach Kerala coast by Saturday, triggering a potential environmental crisis. As per the simulated forecast by INCOIS, the ocean information service provider under the Ministry of Earth Sciences, the oil spill could begin washing ashore between Chavakkad and Kochi by June 14 and Ernakulam coast by June 15. The simulation based on the presumed spill of 100 tonnes of fuel oil starting Wednesday (June 11) was conducted using advanced forecasting models by INCOIS. The agency has warned the state government of potential shoreline contamination and ecological damage owing to the oil spill and has advised immediate response from local authorities. The warning comes three days after the Singapore-flagged cargo vessel Wan Hai 503 caught fire following a container explosion on June 9, approximately 70 nautical miles off the Kozhikode coast. The vessel, which was en route to Mumbai's Nhava Sheva port from Colombo, remains unmanned and adrift.

India to make statement at UN summit
India will be making a statement on ocean protection at the Third UN Ocean Conference (UNOC 3) in France's Nice between June 9 and 13, according to officials. India is presently reviewing the UNOC 3 final declaration that is expected to be adopted at Nice. The text of the declaration was already negotiated in New York in May. It is expected to emphasise the particular importance of implementing the United Nations Framework Convention on Climate Change and the Paris Agreement including the goal to limit the temperature increase to well below 2°C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5°C, recognizing that this would significantly reduce the risks and impacts of climate change, and help ensure the health, productivity, sustainable use and resilience of the ocean and thus common future. It is likely to address sea level rise, plastic pollution and biodiversity loss among others. India will be participating in several panels but the most important ones for it are those on scientific cooperation and sharing of oceanographic data; marine pollution from land; and impacts of biodiversity loss and climate change on the ocean. The Indian delegation will be led by Jitendra Singh, minister of state for earth sciences. Scientists from Ministry of Earth Sciences will also attend. As part of the statement, India will also be calling attention to sea level rise. 'Sea level rise is a very critical issue for tropical countries including India. Apart from sea level rise contributed by melting of glaciers, melting of sea ice in the poles, here sea level rise is contributed by thermal expansion due to global warming. It's a grave threat to populous low lying coastal areas,' said M Ravichandran, secretary, ministry of earth sciences. India will also be participating in a side event with Norway on June 8 to demonstrate marine spatial planning. 'Though our partnership with Norway we have conducted marine spatial planning for Puducherry and Lakshadweep. It is a very important project because it tells us where new industry, township, aquaculture farm, ports or any infrastructure can come up in these coastal regions. This spatial planning can help other countries too because it is about judicious use of land and ocean,' added Ravichandran.
