Multi hazard early warning centre based on WMO plane on the anvil: TN govt

As part of disaster prevention, mitigation and preparedness initiatives, networks including those for lightning and landslide detection and seismic observation would be established with real-time data acquisition platforms, the Tamil Nadu government said here on Friday. Unveiling its new TN State Disaster Management Policy-2023, the TN State Disaster Management Authority said the Chennai-based State Emergency Operation Centre would be upgraded into a state-of-the-art "Multi Hazard Early Warning Centre (MHEWC)" and relocated in a new green building. The MHEWC would be based on the WMO (World Meteorological Organisation) framework. The new policy for disaster management was released by Chief Minister M K Stalin. The centre would engage experts in the fields of meteorology, climate science, atmospheric science, hydrological modelling, emergency analysis, data science, information and communications technology, remote sensing and GIS and Web GIS development. The policy document said th

El Nino expected to return, likely to spike global temperatures: WMO

A warming El Nino event may develop in the coming months , according to a new update from the World Meteorological Organization (WMO). The El Nino event may develop after three consecutive years of an unusually stubborn and protracted La Nina, which influenced temperature and rainfall patterns in different parts of the world, WMO said in a statement. However, while the return of El Nino is considered likely this will be proceeded by a period of El Nino-Southern Oscillation (ENSO) neutral conditions, with 90 per cent probability, during March-May, the statement said. The likelihood of ENSO neutral conditions continuing beyond May decreases slightly but remains high, with 80 per cent likelihood in April-June and 60 per cent in May-July, based on the model predictions and assessment from experts involved in producing the Update, it said. The chances of El Nino developing, while low in the first half of the year, 15 per cent in April-June, gradually increases to 35 per cent in May-July

The impact of warming oceans is a neglected threat

Global sea level rose by 4.5 mm per year during 2013-22 period: WMO

Global mean sea level rose by 4.5 mm per year during the period 2013-22 and human influence was very likely the main driver of these increases since at least 1971, the World Meteorological Department (WMO) said on Tuesday. Sea level rise threatens several low-lying small islands. It is a major threat for countries such as India, China, Netherlands and Bangladesh, some of which comprise large coastal populations. Several big cities on all continents are threatened such as Mumbai, Shanghai, Dhaka, Bangkok, Jakarta, Maputo, Lagos, Cairo, London, Copenhagen, New York, Los Angeles, Buenos Aires and Santiago. It is a major economic, social and humanitarian challenge, the WMO said in a report. Global mean sea level increased by 0.20 m between 1901 and 2018. The average rate of sea level rise was 1.3 mm per year between 1901 and 1971, 1.9 mm per year between 1971 and 2006, and 3.7 mm per year between 2006 and 2018, it said. Sea-level has risen faster since 1900 than over any preceding cent
