Climate scientists forecast that 2024 may be a year of extreme heat and warn of the looming threat of El Niño. El Niño is a climatic phenomenon characterized by the warming of sea surface temperatures in the central and eastern equatorial Pacific Ocean. It occurs irregularly, impacting weather patterns worldwide and often leading to significant disruptions in temperature, rainfall, and atmospheric conditions.
For people and communities alike, it is essential to comprehend the consequences of this projection as the world struggles with the growing problems caused by climate change. The repercussions of global warming are increasingly being felt, from bad weather to the prospect of rising sea levels. Exploring climate action and mitigation methods is crucial given the urgency of the situation and the difficulties that a possibly hot 2024 may provide.
Influence of El Niño on global weather patterns?
El Niño occurs in the tropical pacific ocean and is characterised by higher-than-normal sea surface temperatures in the eastern and central equatorial Pacific, which can have a big influence on global weather patterns. The following are some essential details regarding El Niño:
- El Niño has an erratic weather pattern that can persist for several months to a year or more. It normally happens every two to seven years.
- The phenomena is a component of the El Niño-Southern Oscillation (ENSO), a wider climatic pattern that also includes the opposite phase known as La Nina.
- El Niño episodes are brought on by modifications in atmospheric and oceanic circulation patterns, which interfere with the regular trade winds and modify how warm surface waters are distributed.
- El Niño’s effects can differ regionally and internationally, impacting temperature, rainfall, and weather patterns.
- Some regions get more rain during El Niño, while others could endure drought. Extreme weather conditions including floods, hurricanes, and heat waves may result..
- El Niño may have an impact on the worldwide climate, impacting disease patterns, fisheries, and even agricultural productivity.
To give early warnings and insights into the possible effects of El Niño occurrences, researchers regularly monitor marine and atmospheric metrics. Scientists can predict this climatic phenomenon’s future patterns and get a better understanding of how it influences our climate system.
According to recent findings by climate experts, global temperatures are likely to surge to record levels in the next five years, fueled by heat-trapping greenhouse gasses and a naturally occurring El Niño event. The World Meteorological Organization (WMO) warns that there is a 66% likelihood of exceeding the 1.5°C threshold in at least one year between 2023 and 2027. The WMO also reports that there is a 98% chance that at least one of the next five years, and the period as a whole, will be the warmest on record.
The warming El Niño event is expected to develop in the next few months, and typically, these conditions increase global temperatures a year after they develop, meaning the effects will be seen in 2024. However, the WMO is sounding the alarm that we will breach the 1.5°C level on a temporary basis with increasing frequency. The projections for the warmest year on record in the next five years spell further trouble for the planet, including extreme storms, coral reef die-offs, melting ice, flooding, heatwaves, and drought.

Heat Records on the Horizon: Implications for 2024
The World Meteorological Organization (WMO) has released its annual report on the state of the global climate in 2022, highlighting the continuous advancement of consequences of climate change. The report reveals that extreme weather events such as droughts, floods, and heatwaves affected communities worldwide, leading to significant economic losses. Some notable events were Antarctic sea ice reaching its lowest extent on record, and the unprecedented melting of European glaciers.
The report emphasizes that the years 2015-2022 were the eight consecutively warmest on record, despite the cooling influence of a La Niña event in recent years. La Niña is a climate pattern characterized by cooler than average sea surface temperatures in the central and eastern equatorial Pacific, which can have significant impacts on weather patterns worldwide. Melting glaciers and rising sea levels, which reached record levels in 2022, are expected to persist for thousands of years.
WMO Secretary-General Prof. Petteri Taalas emphasizes the grave impacts of extreme weather and climate events, including food insecurity, mass migration, and economic losses. However, collaboration among UN agencies has proven effective in reducing mortality and economic losses through early warning systems.
The recent findings by the World Meteorological Organization (WMO) indicate that the world is likely to experience record-breaking heat in 2024, which may have significant implications for the planet as listed below
1. Extreme Weather Events
Rising temperatures can fuel the intensity and frequency of extreme weather events such as heatwaves, droughts, hurricanes, and storms. These events can lead to devastating impacts on communities, infrastructure, and agriculture.
2. Water Scarcity
Increased temperatures can exacerbate water scarcity issues, particularly in regions already facing water stress. Higher evaporation rates and changes in precipitation patterns can disrupt water availability for drinking, irrigation, and industrial purposes.
3. Ecosystem Disruption
Record-breaking temperatures can disrupt ecosystems, affecting plant and animal species, food chains, and biodiversity. Shifts in habitats and phenological changes, such as altered blooming and migration patterns, can impact ecosystem functions and ecological balance.
4. Sea Level Rise
Global warming contributes to the melting of glaciers and ice sheets, leading to sea level rise. A record-breaking year could accelerate this process, posing risks to coastal communities, low-lying islands, and vulnerable ecosystems.
5. Health Impacts
Heatwaves associated with extreme temperatures can have severe health consequences, including heat-related illnesses, increased respiratory problems, and heat stress. Vulnerable populations, such as the elderly and those with pre-existing health conditions, are particularly at risk.
6. Agricultural Challenges
Higher temperatures can affect crop yields, disrupt pollination processes, and increase the risk of pests and diseases. These impacts can threaten food security, leading to potential price hikes and food shortages.
7. Economic Costs
The consequences of a record-breaking year can have substantial economic implications. Damage to infrastructure, increased healthcare costs, agricultural losses, and impacts on tourism and industries reliant on natural resources can result in significant financial burdens.
8. Social Displacement
Extreme weather events and environmental changes can lead to forced migration and displacement of populations. This can strain social systems, exacerbate conflicts over resources, and create challenges for humanitarian efforts.
To mitigate the effects of these implications, it is essential to take action to reduce greenhouse gas emissions to net zero. This will require a significant shift towards adopting sustainable practices and implementation of policies that promote climate action. The report highlights the need to be prepared for the consequences of global warming and to take action to mitigate its effects.
The Need for Urgent Attention and Preparedness
Individuals, communities, governments, and international organisations must pay immediate attention to and be ready for the possibility that 2024 could set new records for global temperatures. The possible repercussions of such an event emphasise the urgent need to address climate change and implement preventative steps to lessen its effects.
- Urgent and aggressive climate action is necessary to stop additional temperature increase and mitigate the effects of climate change.
- Switching to renewable energy sources and increasing energy efficiency are crucial steps in reducing greenhouse gas emissions.
