El Nino Has Begun – This Is What It Means For The Planet

El Nino has begun

The planet-warming weather event known as El Niño has officially begun in the Pacific Ocean. US scientists confirmed its status on 9 June 2023, claiming it will make 2024 the world's hottest year – although the effects will begin immediately. Floods and droughts (which, in turn, can spark wildfires such as the one pictured in the Central Coast, Australia) are predicted until the end of this year, mainly threatening islands in the Pacific, as well as the US and Australia.

El Nino has started

El Niño Southern Oscillation, as it's officially called, has three different phases: warm, cold and neutral. It's the El Niño part that's hot, occurring every two to seven years and resulting in a warming of the ocean surface. Record warm years (including 2016, the current hottest) usually happen after a powerful El Niño event, and this one is expected to cause widespread damage to our ecosystems and disrupt global weather patterns. This image shows the varying sea surface temperatures across the globe.

El Nino has started

Overheating from El Niño, combined with human activities, is expected to break a key temperature limit for the first time ever. According to experts, the planet will pass the 1.5°C (2.7°F) global warming threshold before 2027. For context, if we exceeded the 1.5°C every year for a decade, we'd see far greater impacts of warming such as longer heatwaves and extreme weather resulting in intense storms and wildfires.

El Nino has started

Trade winds in the Pacific weaken during El Niño (meaning 'the little boy' in Spanish), while in the event of La Niña (meaning 'the little girl'), they are unusually strong due to its cooling effect. Together, these events can trigger extreme weather such as the record-breaking Cyclone Freddy, which wreaked havoc across parts of Africa including Malawi (pictured) in February and March this year. 

El Nino has started

For Canada and the northern US, El Niño can lead to warmer weather, while the southern US and northern Mexico will experience heavy rainfall, resulting in landslides and flooding (such as those pictured in Kentucky last year). In eastern Australia, El Niño raises the risk of drought, bushfires and heatwaves in what is already expected to be a drier winter and spring than usual.

Read on as we look back at the most destructive weather and weather-related events of the last decade...

2013: 20 May, tornado, Oklahoma, USA

A terrifying tornado tore through Moore, Oklahoma in May 2013. The town experienced three days of extreme weather before the twister spun for around 20 minutes, destroying 300 homes and killing at least 24 people, including nine children. The powerful twister completely devastated the area and left a 14-mile (22.5km) path of destruction in its wake plus £1.5 billion ($2bn) in damages.

2013: May-June, floods, Europe

Heavy rainfall caused huge quantities of flooding across central Europe between May and June 2013, affecting Hungary, Germany, the Czech Republic and Austria, among others. Rising waters from swollen rivers invaded buildings and streets across the region and more than 45,000 people were forced to evacuate. The floods caused billions of euros of damage.

2013: June, Alberta floods, Canada

June 2013 was also a rainy month in Canada, as torrential rain triggered by the melting snowpack of the Rocky Mountains sparked catastrophic flooding in Alberta. At least five people died and thousands had to flee their homes as buildings and roads were completely submerged. The flood damage was as pricey as it was severe, costing Canada an eye-watering CA$6 billion (£3.5bn/$4.5bn).

2013: 8 November, Tropical Storm Haiyan, Micronesia, Philippines, China, Vietnam and Taiwan

The most powerful storm and typhoon of 2013 struck the Philippines on 8 November. The Category 5 storm and super typhoon was one of the strongest ever recorded, with wind speeds of more than 150 miles per hour (241km/h) which completely ravaged the country. The terrifying typhoon smashed buildings and upturned roads killing 6,000 people and injuring thousands as it tore through towns and cities.

2014: 2 June, dust storm, Iran

A freak sand and dust storm engulfed Iran’s capital Tehran in a matter of minutes on 2 June 2014. More than 30 people were left injured and at least four people were killed by the deadly winds which moved at 70 miles per hour (113km/h). The apocalyptic storm resulted in citywide property damage and at least 50,000 people were left with no electricity.

2015: 9-20 January, floods, southern Africa

Severe flooding swept across parts of southeast Africa in January 2015, claiming over 100 lives. Mozambique, Malawi, Madagascar and Zimbabwe were among the countries to experience the heavy rainfall, which affected almost 900,000 people. The excessive flooding submerged houses, washed away livestock and destroyed roads, leaving thousands without food, water or shelter for weeks. The destructive floods caused millions of dollars of damage across the four countries.

2014: September, drought, Brazil

Brazil’s worst drought in 80 years gripped the country back in September 2014. The region's rainfall fell dangerously low and caused lakes and reservoirs to completely dry up. Hundreds suffered water supply cuts in Brazil’s financial capital Sao Paulo alone, prompting a nationwide bid to save water. The deadly drought dried out the country for roughly two years, as Brazil struggled to cope with the intense heat. The drought finally ended after El Niño triggered more rainfall than the country had seen in months.

2015: May-June, heatwave, India

A searing heatwave swept over India during spring and summer 2015 and killed thousands. Unusual winds caused a 'heat bomb' that hit the country with intense temperatures up to 48°C (118°F). The blistering heat caused hundreds to experience severe heatstroke from even a few minutes outside and caused roads to melt in India’s capital New Delhi. The high temperatures are thought to have caused at least 2,300 deaths and only subsided when monsoon rains finally cooled the country.

2016: June-September, floods, China

Torrential rain triggered deadly floods which submerged parts of northern and southern China for months in 2016. Many died from drowning and being trapped by collapsed buildings, and thousands were forced to relocate. The floods were branded the worst to affect the region since 1998, causing a hefty £25.5 billion ($33bn) in damages from wrecked roads and ruined buildings.

2016: September-October, Hurricane Matthew, USA, Puerto Rico and Haiti

Hurricane Matthew struck Haiti on 4 October and its catastrophic scale caused Haiti’s largest humanitarian crisis since the 2010 earthquake. Around two million people were affected by the disaster, which travelled through the Caribbean all the way to the American southeast. The horrific hurricane claimed more than 500 lives and obliterated buildings, roads, crops and water supplies. When Hurricane Matthew eventually hit the US, damages were estimated at around £7.8 billion ($10bn).

2017: 9-18 October, Hurricane Ophelia, Europe

A huge storm swept through western Europe between 9 and 18 October 2017. Hurricane Ophelia was the worst storm to hit Ireland in 50 years, killing three people as it raged through the country. The huge hurricane toppled trees and left more than 120,000 homes without power, while widespread flooding rocked the coast. The hurricane finally died down on 18 October having caused £60 million ($77.5m) of damage.

2017: 25 August, Hurricane Harvey, Texas and Louisiana, USA

Category 4 Hurricane Harvey hit Texas and Louisiana hard when it made landfall in August 2017. The hurricane ripped through Houston and southeastern Texas, triggering huge floods after 51 inches of rainfall swept through the state, killing at least 60 people. The catastrophic hurricane caused around £96.6 billion ($125bn) of damages, the second costliest hurricane recorded in the US since 1900, just after Hurricane Katrina.

2017: June, rains cause landslide, Bangladesh

Severe overnight rain triggered a series of landslides that swept through Bangladesh in June 2017. Roads and communications were completely cut off by the intense rain and at least 133 people died while hundreds were left injured.

2017: August, flood landslide, Nepal

Neighbouring Nepal also faced huge landslides from heavy rain during August. Hundreds of towns and villages were flooded, claiming at least 110 lives as the country experienced over 400mm of rain in just 24 hours. Hundreds were left homeless and without food or water as houses and shelters were completely submerged by high water levels.

2017: 14 August, mudslides, Freetown, Sierra Leone

A muddy hillside on the outskirts of Sierra Leone's capital Freetown collapsed and flooded the city on 14 August. The hill gave way after three days of torrential rain, flooding the city with debris and water. At least 400 people were killed with hundreds missing. The poor drainage systems in the city's outer areas were completely overwhelmed by the high water levels.

2017: August-September, Hurricane Irma, Florida, Puerto Rico and Cape Verde

The strongest Atlantic baseline hurricane ever recorded outside the Caribbean hit eastern US states and parts of South America back in August 2017. Hurricane Irma triggered up to 15 feet (4.5m) of floodwater and left 1.3 million in Florida without power within four hours. The Bahamas was also hit hard by the hurricane’s deadly wake, and roughly 5,000 people were forced to evacuate, the largest number of evacuees in Bahamian history. At least 129 people were killed in total in the southeastern states.

2017: 20 September, Hurricane Maria, Florida, USA and Puerto Rico

Category 5 Hurricane Maria made landfall on 20 September and caused widespread destruction and devastation throughout the US, the Virgin Islands and Puerto Rico. Battered buildings, toppled trees and flooded rivers were left in its deadly wake. Chest-deep floodwaters in Puerto Rico forced people to use paddle boats to seek help and search for survivors. The hurricane is estimated to have caused over £69 billion ($90bn) in US damages and was the worst to hit Puerto Rico in 80 years.

2018: 23 July, wildfires, Attica, Greece

On 23 July 2018, roaring fires engulfed the Attica region of Greece destroying over a thousand buildings. The first fire broke out in a pine forest near Kineta 30 miles (48km) west of Athens, which was followed by major fires northeast of the city. The deadly wildfires are thought to have been triggered by extremely high temperatures during the 2018 European heatwave and possibly arson. It's the second deadliest wildfire of the 21st century so far, with 91 people confirmed dead.

2018: 8 November, Camp Fire, California, USA

The deadliest and most destructive wildfire in California's history caused 85 deaths and destroyed 18,800 buildings as it swept through the town of Paradise in Butte County. The blame lies with PG&E electrical transmission lines, coupled with a 200-day drought and strong winds before the fire started. The tinder-dry land was an easy target for the flames to spread. The Camp Fire was the costliest disaster worldwide in 2018.

2019: January, polar vortex, Chicago, USA

Polar ice winds swept across the Midwest in January turning Chicago into an icy wasteland. Temperatures dropped to a record-breaking -31°C (-23°F), chilling the city and leaving hundreds stranded in the snowy weather. It wasn’t until mid-March that the freezing temperatures finally rose. The deep freeze cost retailers and restaurants alone up to £780 million ($1bn).
