World: Global Seasonal Outlook (September 2026)

Country: World Source: World Food Programme Please refer to the attached file. SPECIAL FOCUS : El Niño Outlook – September 2026 A Very Strong El Niño Is Virtually Certain, with Growing Confidence in a Historic Event El Niño has strengthened, with the 3-month RONI rising from +1.0°C (MJJ) to +1.4°C (JJA), and is projected to reach peak intensity during October to December (OND). A very strong El Niño event (RONI > +2.0°C) is considered virtually certain (98% probability) during OND (Figure 1). Forecast confidence has strengthened, with the likelihood of a record-breaking El Niño event increasing from 69% to 75%. A 3-month RONI exceeding +2.5°C would surpass all events observed since 1950. Over the past month, El Niño has continued to strengthen, with sea surface temperature (SST) anomalies exceeding +3.0°C across the eastern equatorial Pacific. September forecasts (Figure 2) indicate a rapid intensification of El Niño conditions. Niño 3.4 SST anomalies are projected to peak during the OND season, with the ensemble median approaching +2.7°C. Confidence in the development of a historically strong event has increased, with a 75% probability that this threshold will be reached. If these conditions materialize, the current El Niño would become the strongest event observed since 1950. An event of this magnitude would substantially increase the likelihood of widespread and significant El Niño-related impacts worldwide. Following its peak, a gradual weakening is expected, with SST anomalies forecast to return to neutral conditions by the April to June.

World: Super El Niño threatens to push 8 million children into acute hunger across East and Southern Africa by early 2027 – Save the Children

Country: World Source: Save the Children NAIROBI, 22 September 2026 – About 8 million children across East and Southern Africa could face acute hunger by early 2027, a rise of 30%, as one of the strongest El Nino weather events in recent years fuels a growing food crisis, according to new analysis by Save the Children. Analysis of recent data from global hunger monitor, the Integrated Food Security Phase Classification (IPC), found that the number of people facing crisis levels of hunger or worse (IPC Phase 3+) in six countries is expected to surge from 12.6 million people to 16.4 million by March 2027 driven in part by the impacts of the looming “Super” El Niño. Currently six million children in those six countries are experiencing severe food shortages [1] but this is set to rise to eight million in the next few months unless urgent action is taken, Save the Children said. The agency’s analysis only covered countries with recent IPC reports where El Niño is projected to have devastating impacts including Madagascar, Malawi, Mozambique, Zambia, Uganda and Kenya. New hunger data is due out shortly for Somalia which has already been flagged for being at risk of El Nino-related floods . Uganda is projected to have the highest absolute number of people facing acute food insecurity in coming months, with 4.4 million people expected to be in crisis or worse levels of hunger by early 2027 – a 22% increase on previous figures. The situation is particularly bad in the Karamoja region of northeastern Uganda which has seen an increase of more than 40% in the number of people facing crisis or emergency food insecurity. Zambia is forecast to experience the sharpest deterioration, with the number of people facing crisis-level hunger rising by 80% to over 1.2 million people, while Madagascar, Mozambique and Malawi are expected to see increases of 75%, 55% and 35% respectively. While food security is expected to improve in Kenya overall by the start of 2027, having already deteriorated this year, the situation among refugees in the country is expected to deteriorate due to El Niño-related flooding. In Mozambique, the forecast comes as many communities in the central provinces are still recovering from severe flooding earlier this year, while conflict driven- displacement in Cabo Delgado continues to put pressure on food, water and health services. In Madagascar, about 502,000 children aged under 5 - or one in 10- are expected to suffer from acute malnutrition between May 2026 and April 2027. This includes about 78,000 children expected to have severe acute malnutrition, the most deadly form of malnutrition requiring urgent medical treatment [2]. The worsening food crisis across much of the region comes as a result of one of the strongest El Niño weather events in recent years, coupled with record-breaking global temperatures, a deadly combination that will cause dangerous droughts, crop failures and livestock losses across parts of Southern Africa. At the same time, the El Niño phenomenon will cause devastating floods in parts of East Africa, pushing already vulnerable families deeper into crisis. Save the Children said El Niño is unfolding against a backdrop of conflict, hunger, displacement, economic instability and humanitarian funding cuts. Without early action, the aid agency said, climate shocks are likely to compound existing vulnerabilities and deepen humanitarian needs, particularly for children and their families. Yvonne Arunga, Regional Director for Save the Children in East and Southern Africa, said: "Hunger is not just about empty stomachs. Children who do not have enough nutritious food are more likely to become malnourished, fall ill, miss school and face increased risks of exploitation and abuse. The longer families go without support, the harder it becomes for children to recover . “When families' livelihoods are destroyed by floods or drought, children may face greater risks of child labour, trafficking, neglect, violence, forced early marriage, and other forms of exploitation. “We know El Niño is coming. We know which children are most at risk. And we know that anticipatory action works. Governments must turn early warnings into early action to protect essential services like schools, hospitals, water and social protection systems, before the crisis hits. The international community and donors must invest now, before droughts, floods and food crises escalate. Every dollar spent helping communities prepare and act early can save lives, protect livelihoods, and reduce the need for much larger humanitarian responses late r .” Save the Children has invested significantly in anticipatory action, taking practical action ahead of forecasted shocks to reduce impacts on children and communities. Across the region, Save the Children is helping families prepare for floods, storms and droughts such as through early warning information targeted at children, evacuation planning, strengthening of community preparedness, and anticipatory cash assistance to allow families to prepare for disasters. Save the Children is also reinforcing health facilities, schools and water systems so they can better withstand floods, droughts and other climate-related shocks. Ends. Notes to Editors: [1] Save the Children compared the most recent Acute Food Insecurity analyses (IPC Phase 3+) from six countries in East and Southern Africa; the countries were selected due to having IPC analyses with a validity period as of September 2026 and a projection that looks ahead into the end of 2026/ the first quarter of 2027 when the effects of El Niño are expected to peak. In all cases, Save the Children compared the number of people currently facing IPC3+, with the projected figure for early 2027 within the same analysis report. The number of children in IPC3+ for each country was estimated by looking at the total number of people facing IPC3+ levels of food insecurity, and applying the national share of children in the population according to the UN’s World Population Prospects 2024 revision.

‘Jaw-dropping’: Super El Niño bursts through temperature record months ahead of peak

The ‘Godzilla-level’ phenomenon is supercharging the climate crisis and will heavily impact communities across the world The “jaw-dropping” El Niño currently heating up the planet has burst through the highest temperature ever recorded for the phenomenon, several months ahead of its expected peak. The latest data shows the temperature rise at the heart of El Niño in the Pacific ocean has now reached 3.05C. That is higher than the 3.02C set in late November 2015, the previous high set in the 150 years of modern records. This temperature is measured against the average of 1991-2020. Continue reading...

Ethiopia: IGAD High-Level Call to Action on El Niño Preparedness, Anticipatory Action and Resilience

Countries: Ethiopia, Kenya, Somalia Source: Intergovernmental Authority on Development Please refer to the attached file. Adopted at the IGAD Regional High-Level Forum on El Niño Preparedness for the Horn of Africa Addis Ababa, Ethiopia, 17 September 2026 --------------------------------------------------------------------------------------------------------------------------------- We, the Ministers, Commissioners and Heads of Delegation of the Member States of the Intergovernmental Authority on Development (IGAD), meeting in Addis Ababa, Ethiopia, on 17 September 2026 at the IGAD Regional High-Level Forum on El Niño Preparedness for the Horn of Africa, Noting with concern that El Niño conditions have developed and are expected to strengthen through the remainder of 2026, and that the regional climate outlook issued by the IGAD Climate Prediction and Applications Centre (ICPAC) and the National Meteorological and Hydrological Services (NMHSs) of the region indicates an increased likelihood of wetter-than normal conditions over much of the equatorial and southern parts of the region during the October to December (OND) 2026 season, with the highest probabilities over southern Ethiopia, central and southern Somalia and north-eastern Kenya; Recalling the severe impacts of past El Niño episodes, including the floods of 1997–98 and of 2023, the latter of which claimed lives and displaced people across Ethiopia, Kenya and Somalia, and noting that damage to critical infrastructure in these episodes impeded access and rescue, disrupted essential services and prolonged recovery; Concerned that many communities face a rapid transition from prolonged dry conditions to heavy rains which, while replenishing water and pasture, heighten the risk of flash and riverine floods, landslides, displacement, outbreaks of human and transboundary animal diseases (TADs), concentration of livestock around water and grazing resources, rangeland degradation and the disruption of established pastoral mobility routes; Noting the evidence that every US$1 invested in anticipatory action can save up to US$7 in avoided losses, Mindful that climate hazards compound existing conflict, displacement and economic pressures in the region, including disruptions to maritime trade and supply routes through the Red Sea and the Gulf of Aden, that they can intensify competition over shared natural resources, and that they arrive at a time of severe constraints on humanitarian financing; Acknowledging rangelands and shared river basins as transboundary assets that sustain pastoralism, food security, biodiversity and borderland economies, and whose shared management is essential to peaceful coexistence; Guided by the Sendai Framework for Disaster Risk Reduction 2015–2030, in particular its Priority 4 on enhancing disaster preparedness for effective response and its global target (g) on multi-hazard early warning systems and disaster risk information; Articles 7 and 8 of the Paris Agreement, which identify early warning systems, emergency preparedness and risk insurance among the areas for cooperation; the United Arab Emirates Framework for Global Climate Resilience, which sets the target that “by 2027 all Parties have established multi-hazard early warning systems”; the Early Warnings for All initiative of the United Nations SecretaryGeneral; and targets 1.5 and 13.1 of the Sustainable Development Goals; Recalling Agenda 2063: The Africa We Want and its goal of environmentally sustainable and climate resilient economies and communities; the Programme of Action for the Implementation of the Sendai Framework for Disaster Risk Reduction in Africa; the African Union Climate Change and Resilient Development Strategy and Action Plan (2022–2032); the Africa MultiHazard Early Warning and Early Action System (AMHEWAS) Programme; the Kampala Ministerial Declaration on Migration, Environment and Climate Change and its continental expansion in 2023; and the African Union Convention for the Protection and Assistance of Internally Displaced Persons in Africa (Kampala Convention), under Article 4(2) of which States Parties “shall devise early warning systems” in areas of potential displacement; Welcoming the Addis Ababa Call to Action on Early Warnings in Africa, adopted at the Africa Early Warnings Forum held in Addis Ababa from 2 to 4 September 2026; Affirming that each State bears the primary responsibility to prevent and reduce disaster risk, as recognised in the Sendai Framework, and that international cooperation, as envisaged in its global target (f), serves “to complement their national actions”; Taking note of the findings of the technical segment of this Forum, held on 15 and 16 September 2026, and of the Regional Preparedness and Early Action Technical Annex, which accompanies this Call to Action and sets out country and regional priority actions, responsibilities and timelines; Recognising that the window for action before the onset of the OND rains is now a matter of weeks, and that effective preparedness requires timely climate information, pre-agreed anticipatory action, adequate and predictable financing, resilient systems and strong cross border cooperation; Hereby issue the following Call to Action: A. OUR COMMITMENTS AS IGAD MEMBER STATES We commit to: Activate plans before the rains. Review, update and activate national and subnational contingency plans and emergency coordination structures before the onset of the OND season, and implement the country priority actions, responsibilities and timelines set out in the Technical Annex, giving priority to the highest-risk areas, with clear arrangements for evacuation, shelter, humanitarian access and the protection of vulnerable and displaced people, consistent with our respective national, regional and international obligations. Pre-position and protect. Pre-position food, health, water, sanitation and hygiene (WASH), veterinary and agricultural supplies in at-risk areas, and protect critical infrastructure and essential services, including roads, bridges, flood defenses, schools, health facilities and water systems. Prepare health systems for flood-related outbreaks. Strengthen surveillance, early detection and response capacity for water-borne and vector-borne diseases, including cholera, malaria and Rift Valley fever, in line with the International Health Regulations (2005) and through a One Health approach that links human and animal health services. Protect agriculture, livestock and food systems. Translate forecasts into timely advisories on planting and harvesting, protect seed and food stocks and productive land, vaccinate livestock ahead of the rains, manage grazing pressure and support early and orderly livestock movement where necessary. Make financing move on triggers. Define or update anticipatory action triggers and pre-agreed actions, and use contingency budget lines, shock-responsive social protection, disaster risk insurance at national and local levels, and other disaster risk financing instruments to release resources as soon as agreed thresholds are reached. Invest before disasters occur. Progressively increase, within national budgetary processes, domestic allocations for disaster preparedness, early warning, anticipatory action and resilience, recognising, as the annexed scenarios illustrate, that each dollar invested before a disaster can avert several dollars in recovery costs. Share information across borders. Share forecasts, river flow and flood warnings, and human and animal disease alerts in a timely manner with neighbouring Member States, particularly for shared river basins, pastoral corridors and other transboundary risk areas, and draw on the disaster-related provisions of the Protocol on Free Movement of Persons in the IGAD Region and on the IGAD Protocol on Transhumance to keep cross-border movement safe, orderly and dignified. Reach the last mile. Ensure that warnings reach at-risk communities in time, in local languages and accessible formats, with clear guidance on what to do, and that communities, pastoralists, farmers, fisherfolk, women, youth, persons with disabilities, local authorities and traditional institutions are engaged in risk assessment, preparedness planning and early action. Build longer-term resilience. Integrate climate and disaster risk into national development plans, public investment programmes and sectoral policies, including investment in resilient infrastructure, climate-smart agriculture, sustainable land and rangeland management, infrastructure to capture and store wet-season water for water, energy and food security, and durable solutions for displacement-affected populations. Close the early warning gap by 2027. Accelerate national implementation of the Addis Ababa Call to Action on Early Warnings in Africa, in pursuit of the Early Warnings for All goal of universal coverage by the end of 2027 and the corresponding target of the UAE Framework for Global Climate Resilience. B. CALL TO ACTION FOR THE IGAD SECRETARIAT AND ITS SPECIALISED INSTITUTIONS We call upon the IGAD Secretariat, ICPAC and other IGAD specialised institutions to: Keep the region informed throughout the season. Provide regular, reliable and actionable updates, including monthly, weekly and flood forecasts, and translate them into impact-based information and early warning to early action protocols that Member States, partners and communities can act upon, including through the IGAD Disaster Operations Centre at ICPAC and its link with the continental AMHEWAS situation room. Coordinate the regional response to transboundary risks. Convene regular coordination among Member States and partners throughout the OND season, building on existing IGAD platforms and national early warning systems and improving their interoperability, and support joint monitoring, surveillance and information sharing on floods, pests and diseases across shared river basins, pastoral corridors and displacement routes. Anticipate transboundary animal disease risks. Through the IGAD Centre for Pastoral Areas and Livestock Development (ICPALD), strengthen integrated early warning to identify areas at heightened risk of TAD outbreaks linked to rainfall, flooding, livestock concentration, wildlife and livestock interaction and cross-border movement, and support harmonised surveillance, vaccination and veterinary certification. Safeguard cross-border mobility and shared rangelands. Support Member States to operationalise the IGAD Protocol on Transhumance, including agreed livestock corridors, joint management of shared pasture and water, protection of strategic grazing reserves and conflict-sensitive approaches that reduce competition over resources. Scale up anticipatory action and risk financing. Develop common regional approaches and tools, document and share good practice, and build bankable crossborder resilience project pipelines to mobilise resources for preparedness, early action and resilience. Track, measure and report. Monitor implementation of this Call to Action and its Technical Annex; with Member States and partners, refine the annexed scenarios into a regional assessment of the costs incurred and the losses averted; report on both to the IGAD Council of Ministers; and convene a regional post-season review in the first quarter of 2027 to capture lessons from the OND 2026 season. C. CALL TO ACTION FOR DEVELOPMENT AND HUMANITARIAN PARTNERS We invite development and humanitarian partners to join us in: Aligning behind national and regional priorities. Anchoring technical and operational support in Member State plans and the IGAD regional preparedness and resilience agenda, reducing fragmentation and duplication, and working with accredited multilateral delivery partners to design and implement large-scale, multi-country adaptation programmes. Acting before the peak. Scaling up early warning to early action in the weeks ahead, including anticipatory cash transfers, protection of crops, water sources and productive assets, strategic livestock vaccination and health campaigns, fodder preparedness and early management of grazing pressure. Programming across borders. Supporting cross-border and regional programming where risks, populations, ecosystems and markets transcend national boundaries, including humanitarian logistics, regional pre-positioning and access arrangements that account for disrupted supply routes. D. PARTNERSHIP WITH DONORS, FINANCIAL INSTITUTIONS AND RESOURCE PARTNERS Having set out our own commitments, and in a spirit of shared responsibility, we invite bilateral and multilateral donors, international financial institutions, climate funds, development banks and the private sector to join us in: Investing early, where it counts most. Providing predictable, timely and flexible financing for preparedness and anticipatory action ahead of the OND peak, where, as the annexed scenarios show, each contribution made before the rains averts several times its value in recovery costs, consistent with the case for scaling up investment in disaster risk reduction and pre-arranged financing affirmed in the Compromiso de Sevilla, adopted at the Fourth International Conference on Financing for Development in 2025. Pre-arranging finance. Expanding pre-arranged risk financing mechanisms, including risk insurance at national and local levels, that release resources rapidly when agreed early warning triggers are reached, and favouring coherent, nationally owned and regionally coordinated resilience pipelines over fragmented emergency appeals. Keeping existing funding agile. Including crisis modifiers and reallocation flexibility so that governments and partners can move rapidly from forecast to preparedness, from preparedness to anticipatory action, and from response to resilient recovery. E. CALL TO ACTION FOR COMMUNITIES, LOCAL ACTORS AND THE MEDIA We call upon communities, local actors and the media across the IGAD region to: Heed and share official warnings. Follow the forecasts and advisories of NMHSs, ICPAC and local authorities; take early protective action to safeguard lives, livestock, crops, water and property; support and protect the most vulnerable; contribute local knowledge to risk-informed decisions; and, in the case of the media, amplify verified early warning information and counter misinformation. OUR SHARED RESOLVE We recognise that climate and disaster risks do not respect national borders, and that no single country or institution can manage them alone. We commit to a whole-of-government and whole-of-society approach that brings together governments, IGAD, the United Nations system, development and humanitarian partners, donors, civil society, the private sector, the media and communities. We reaffirm that early warning without early action is insufficient; that early action without predictable financing cannot be sustained; and that emergency response alone cannot build resilience. We resolve to turn this Call into concrete, financed and measurable action, with clear responsibilities and timelines, building on existing national and local preparedness efforts, to account openly for what we deliver, and to review our progress together at the close of the season. Adopted in Addis Ababa, Ethiopia, on 17th September 2026.

‘The physical toll is visceral’: How Indonesia’s fire haze affects millions - visual guide

Intensified by this year’s super El Niño, fires in Borneo and Sumatra are emitting toxic air for swathes of the population in Indonesia and its neighbours For months, parts of Indonesia’s Borneo and Sumatra islands have been ablaze. The fires are sometimes lit illegally as a cheap way to clear land for plantations of oil palm, of which Indonesia is the world’s largest producer. So prevalent is the technique that it even has a special term: slash and burn. Continue reading...

World: Locust Watch: Seasonal precipitation predictions in the Desert Locust summer and winter breeding areas (October 2026–March 2027) (20 September 2026)

Countries: World, Algeria, Chad, Djibouti, Egypt, Eritrea, Ethiopia, India, Iran (Islamic Republic of), Libya, Mali, Mauritania, Morocco, Niger, Oman, Pakistan, Saudi Arabia, Somalia, Sudan, Tunisia, Yemen Source: Food and Agriculture Organization of the United Nations Please refer to the attached file. The dynamical models indicate above-normal rainfall across most of northern and eastern Africa and the Middle East from October through December, consistent with previous strong El Niño episodes. Within this region, drier-than-normal conditions are expected to emerge across North Africa by December, but elsewhere the wet pattern is likely to persist through winter. The only notable change in the forecasts this month is that the predicted wet anomaly is somewhat less pronounced in East Africa, and the forecast has also turned drier for Yemen and Oman, because the positive phase of the Indian Ocean Dipole is struggling to become established, and a less positive IOD favors relatively drier conditions around the northwestern Indian Ocean during El Niño. Nevertheless, the pronounced El Niño forcing will remain the dominant (wet) influence. These rainfall patterns can support breeding in the northern Sahel through late summer breeding season. Small-scale breeding may begin in October along the Red Sea and Gulf of Aden coasts. Precipitation

El Salvador: Latin America & The Caribbean Weekly Situation Update as of 18 September 2026

Countries: El Salvador, Colombia, Dominica, Guatemala, Haiti, Honduras, Saint Lucia Source: UN Office for the Coordination of Humanitarian Affairs Please refer to the attached Infographic. KEY FIGURES 500K increase in people in Honduras expected to be food-insecure compared to 2025 137K people assisted across 53 municipalities following 10 August earthquake in Colombia 253K children (6-59 months) in Haiti expected to suffer acute malnutrition through May 2027 CENTRAL AMERICA: DROUGHT Across the Central American Dry Corridor, El Niño-linked drought is damaging crops, straining water supplies and forcing families to buy grain they normally grow. In El Salvador’s La Unión department, rain has stopped for up to 45 days; rural households receive water once or twice weekly. In Honduras, El Triunfo’s municipal government declared an emergency, prepared food rations and sought new water sources. On 16 September, Guatemala announced US$65.5 million in food assistance for 1.2 million families through December, with most deliveries in November and December. Packages would cover 73 per cent of a five-person household’s monthly calorie needs. The World Food Programme expects drought to push at least 500,000 more Hondurans into food insecurity than last year. CARIBBEAN: DROUGHT The Caribbean Institute for Meteorology and Hydrology forecast emergency-level drought in Dominica and Saint Lucia by the end of November, projecting a shift from warning level in both countries. The outlook points to short-term drought in Dominica and long-term drought in Saint Lucia as El Niño threatens to deepen rainfall deficits across the Lesser Antilles. In Dominica, lower soil moisture and river flows could strain farms and water supplies. Saint Lucia depends heavily on surface water for drinking. Rains replenished supplies in May, but shortages in its north had already prompted plans for water truck deliveries. The institute considers emergency level a signal of immediate concern; national authorities decide whether to issue formal drought declarations. COLOMBIA: EARTHQUAKE As of 17 September, Colombia’s 10 August earthquake had affected 486,917 people, up from 466,606 on 4 September, with 335 deaths. The number of homes registered as uninhabitable rose from 73,378 to 104,037, though the registry may still contain duplicates. Across four priority departments, 6,903 people are staying in 105 temporary shelters. In Buenaventura, 13 of 18 active shelters lack basic hygiene and environmental safeguards; limited safe water and poor sanitation raise disease risks. Humanitarian organizations report assisting 137,000 people in 53 municipalities, up from 123,000 in 49 municipalities at the beginning of September. International contributions have reached at least US$47 million. The Government has begun temporary cash payments to registered survivors in Chocó and Valle del Cauca. HAITI: FOOD SECURITY/NUTRITION An analysis led by Haiti’s Ministry of Public Health and Population, with support from UNICEF, FAO, WFP, WHO and nutrition partners, projects acute malnutrition among 253,725 children aged 6–59 months between June 2026 and May 2027, including 93,873 severe cases. Another 25,750 pregnant and breastfeeding women will need nutritional support. Armed violence disrupts access to food and care. From December 2026 to May 2027, 29 of Haiti’s 140 municipalities could face Serious conditions on the IPC acute malnutrition scale, while Cité Soleil and Cabaret could reach Critical, the second-highest phase. The analysis warns that rising needs will put further pressure on nutrition services that many families already struggle to reach.

‘Forcing a reckoning’: How Asia is preparing for a ‘supersized’ El Niño

From Sri Lanka to South Korea, governments are preparing for droughts, wildfires, typhoons and floods – with climate plans facing their biggest challenge to date Asian governments are rushing preparations for the most severe El Niño weather event on record, with hundreds of millions of people bracing for multiple crises at once as extreme heat, heavy rain and food shortages hit the region. Fuelled by exceptionally warm ocean conditions across the tropical Pacific – and developing alongside the human-driven climate crisis – El Niño is virtually guaranteed to grow to a very strong intensity towards the end of this year and into 2027.

Food security under pressure from conflicts, extreme weather

Extreme weather and violent conflicts are threatening food production and trade across the globe. Experts are forecasting a super El Niño, which could further disrupt planting and harvests – and push millions more people into acute food insecurity. Meanwhile the ongoing wars with Iran and Ukraine are disrupting shipping and supply chains.  Shawn Arita, Associate Research Professor at North Dakota State University, believes that transport problems outweigh supply concerns. "The food does exist, the availability does exist. The main issue currently speaking is that the movement is broken."

Planet’s atmosphere breaks record for water vapour levels increasing risk of extreme heat and rainfall

Global heating contributes to record, with a warmer atmosphere able to hold more water, scientists say The planet’s atmosphere held more water vapour in August than any other month on record, further increasing the risk of extreme heat and rainfall around the world, according to Europe’s climate change service. Climate scientists said global heating was a contributor to the record because a warmer atmosphere can hold more water, and the historic El Niño in the Pacific Ocean was also likely pushing water vapour levels up.
