However, resource-poor regions may struggle to adapt in time, raising questions about their resilience to natural hazards. Guterres has called on the WMO to help ensure that every person on Earth is protected by early warning systems within five years. The impact of the current drought is not limited to the environment but also has significant economic and ecological consequences.ĭespite the increasing number of extreme weather events, data collected in 2022 revealed that only half of WMO member states have systems in place to inform people and governments of impending hazardous weather. This initiative aims to close gaps in early warning systems, especially in developing countries, and link them to policies, communications, and emergency response plans. One of the main priorities is the Early Warnings for All Initiative, launched by UN Secretary-General Antonio Guterres at COP27 in 2022. To help prepare for the extreme weather events associated with El Niño, experts will discuss strengthening weather services to support climate change adaptation at the upcoming World Meteorological Congress. Preparing for the heatwave: Early warning systems and resilience Although the WMO report does not indicate a permanent exceedance of the 1.5☌ warming level outlined in the Paris Agreement, it warns of temporary breaches occurring with increasing frequency. Higher temperatures can lead to more extreme weather events, sea-level rise, melting ice and glaciers, as well as ocean heat and acidification. This could have significant impacts on health, food security, water management, and the environment. WMO Secretary-General Petteri Taalas warns that the combination of a warming El Niño and human-induced climate change will push global temperatures into “uncharted territory”. With a 98% chance of at least one year between 2023-2027 being the hottest on record, experts are concerned about the far-reaching repercussions of this heat surge. Privacy Policy Record-breaking temperatures and repercussions to collect the amount shown above from my account periodically. In addition, El Niño events can reduce fish stocks for South American fishing communities, as less cold water rises and fewer nutrients are available for marine species like squid and salmon. For example, the 2014-16 El Niño phase caused crop failure and damaged food security for over 60 million people, according to the UN Food and Agricultural Organisation.
The last three years have experienced cooling effects from La Niña episodes, but with the phenomenon ending in March 2023, the upcoming El Niño will likely cause a surge in global temperatures.Įl Niño events can also lead to extreme weather conditions such as droughts, floods, and heatwaves. On the other hand, La Niña creates stronger trade winds, leading to warm water off Asia and cold water near the Americas, causing a slight decrease in global temperatures. During El Niño, weaker trade winds cause warm water to spread towards the Americas, resulting in increased global temperatures. El Niño’s impact on global weather patternsĮl Niño and La Niña are part of the El Niño Southern Oscillation (ENSO) system, which influences global weather patterns. The WMO’s report also states a 66% chance of annual average surface temperatures between 2023-2027 being more than 1.5☌ above pre-industrial levels for at least one year, temporarily breaching Paris Agreement targets. There is a 98% chance that at least one of these years, and the entire period, will be the warmest on record.
The World Meteorological Organization (WMO) has warned that the combination of heat-trapping greenhouse gases and an El Niño event will likely lead to record global temperatures in the next five years.
