Extreme weather events across the world in 2023 so far

In the midst of 2023, the impacts of climate change are already evident, with devastating extreme weather events making headlines around the world, causing loss of life and livelihoods. Record cyclones, forest fires, heat waves and ice storms have shown that climate change is a present reality.

According to the latest IPCC report, if collective inaction continues, we could see a temperature rise of 1.5 degrees Celsius by the early 2030s, leading to even more frequent and intense extreme weather events. Climate experts warn that these events could soon become the "New Normal."

"Extreme heat events are more extreme than ever," Stephanie Herring, a scientist at the National Oceanographic and Atmospheric Administration (NOAA), told NPR. "Research is showing they're likely to become the new normal in the not-so-distant future."

Carbon Brief says that there is growing evidence linking human activity to an increased risk of extreme weather events, such as dangerous heat, droughts, floods and heavy rains. According to the Climate Data Analysis website, more than 70% of these events globally are intensified by human-induced climate change.

These extreme weather events are on the rise as temperatures continue to rise. The United Nations reported a significant increase in weather-related disasters in the past two decades.

The IPCC issued a dire "final warning" this year, urging immediate action to curb carbon emissions. Temperatures are already 1.1°C higher than pre-industrial levels, and breaking the 1.5°C mark would make it extremely difficult, if not impossible, to reverse global temperature rise.

In July 2023 we have seen

In South Korea, over 40 people died due to floods - at least 7 of whom were trapped in their vehicles in a tunnel during the flood. Kurume, in southwest Japan, reported 402.5 mm of rain, the highest ever recorded, while Fukuoka, Yamagucho and Shimane were also heavily affected by the rain - over 1.7 million residents were impacted. Devastating floods were experienced in Guatemala and Somalia, where the rain destroyed crops and inundated whole villages. China’s Hunan saw its worst flooding in 50 years, which caused widespread damage and casualties in parts of Chongqing and Yunnan too. Similar devastating floods were seen in Indonesia and Brazil. Parts of Ireland were flooded after the second wettest 24 hours on record for those counties.

Food security: Countries not directly impacted by climate catastrophes might feel its effects later on in 2023, as harvests from climate-vulnerable countries and crop-producing regions are hit by extreme heat, drought and flooding, having implications for the global breadbasket. In particular, scientists say that heatwaves are threatening food security because of major crop losses in different regions - such as soybean and rice - affecting global prices and food availability.

So far impacts to agriculture in July include: Indian government banned export of non-basmati white rice due to rain, triggering panic buying and price rises abroad, crops damaged in Mexico, US, Italy, Spain, North Africa, Iraq, China, Australia due to heatwaves, farmers cannot plant less rice in Thailand due to drought, drought is affecting crops in Uruguay, milk production down in Puerto Rico, Italy due to heat, livestock dying of heat in Mexico, Niger, the heatwave is set to affect Caribbean and Mediterranean fisheries, hail affected crops in Italy. Due to flooding, particularly in Ivory Coast, cocoa prices are up more than 25% in 12 months. Cereal production in southern Europe is expected to fall by up to 60% compared to last year due to the summer heatwaves, and will likely be the lowest harvest since 2007. Northern Italian tomatoes down 15% due to floods, price rises on the way.

India

In Europe, the European Space Agency warned of an unprecedented heat wave that would hit Sicily and Sardinia in Italy. Forecasters predicted a staggering high of 48 degrees Celsius, which could make it the hottest temperature ever recorded on the continent.

In Greece, a firestorm ravaged the landscape, causing chaos and forcing hundreds of people, including children attending summer camps, to evacuate coastal towns outside of Athens.

Across the Atlantic in the United States, the National Weather Service sounded alarms as a "widespread and oppressive" heat wave engulfed southern and western states, affecting more than 80 million people. The notorious Death Valley was hardest hit, with temperatures reaching a near-record 52 degrees Celsius, while wildfires raged in southern California.

East Asia caught no respite as Japan issued heatstroke warnings for tens of millions of citizens. Near-record highs scorched several regions, further exacerbating the impact of the heat wave.

Cyclone Freddy

Cyclone Freddy made landfall in southern Africa in February, causing the death of more than 400 people across Mozambique, Malawi, and Madagascar, and displacing 80,000 people.

"Although it is 'tricky' to say whether climate change solely caused the cyclone, it is said that climate change likely enhanced the amount of rain which fell, especially during its time over land, as warmer air can hold more water" the BBC.

It was reported to be “one of the longest-lived storms” ever recorded in the Southern Hemisphere and, in a testament of its strength, it surpassed the previous accumulated cyclone energy record, beating the previous record set by Cyclone Fantala in 2016.

Floods in California

In a remarkable turn of events, the United States experienced its third wettest January on record this year, as reported by the National Oceanic and Atmospheric Administration. California, in particular, witnessed an extraordinary increase in rainfall compared to previous years.

The Golden State found itself pummeled by an astonishing 31 atmospheric river storms within a few months, as described by the Los Angeles Times. These weather phenomena transport moisture-laden air from the tropics to higher latitudes, as explained by CNN. Their impact was significant, bringing forth heavy rain, posing a flood threat, and blanketing the region with heavy snow, leading to hazardous travel conditions and strong winds gusting at hurricane-force levels.

Warm winter in Europe

This year, Europe experienced its second warmest winter on record, as a formidable wintertime heat dome descended upon the continent, leading to the temporary closure of numerous ski resorts, as reported by The Washington Post.

Euronews stated that the average temperature during this winter was approximately 1.4 degrees Celsius warmer than the average for the period from 1991 to 2020, trailing behind only the winter temperatures of 2019-2020.

India Monsoon Evacuations

Severe monsoon flooding has wreaked havoc in six north Indian states, claiming the lives of at least 91 people and affecting millions more. Record rainfall has transformed schools and colleges into disaster relief camps, causing waterlogging, road collapses, and destruction of homes in several regions of northern India.

Heavy rains have hit the Himalayan state of Himachal Pradesh the hardest, causing at least 45 deaths since July 7. The heavy rains have destroyed thousands of acres of agricultural crops and stranded tens of thousands of people in Uttarakhand.

Historic Flooding Hits Vermont

Vermont, USA, faced an unprecedented deluge of rain, breaking records and causing severe flooding. Officials declared a state of emergency after the Winooski River breached its banks, exacerbating the devastation caused by two months of heavy rain.

“Make no mistake, the devastation and flooding we’re experiencing across Vermont is historic and catastrophic,” Governor Phil Scott told CNN.

The recent historic flooding has been considered the most severe natural disaster since the devastating floods of 1927, claiming many lives and causing extensive devastation.

Intense tropical storm Mawar

Tropical Storm Mawar, the most potent cyclone of the year, struck Guam, the Philippines, Taiwan, and Japan with its relentless force. With peak winds reaching 175 mph and gusts up to 210 mph, the super typhoon inflicted widespread destruction and highlighted the urgency of climate change concerns in the region.

At the end of May and early June, Typhoon Mawar affected Guam, the Philippines, Taiwan, and Japan, causing unusually intense conditions.

Mawar became a super typhoon, with peak winds jumping to 175 mph with gusts near 210 mph, reported as the strongest tropical cyclone globally so far in 2023.

Jefferson Chua, a campaigner from Greenpeace Philippines, emphasizes that the Philippines is consistently experiencing a climate emergency. The occurrence of super typhoons has now become commonplace, in addition to enduring long-term consequences, like droughts, rising sea levels, and depletion of resources.

Wildfires ravage Canada

Canada experienced an unparalleled start to the wildfire season, with over 900 active wildfires, and more than half considered out of control. Extreme dry weather and a subsequent heatwave contributed to the unprecedented blaze, displacing thousands and causing dangerous air quality conditions across the US and Canada.

Physical impact: wildfires

Cascading/human impacts:

  • A million people across Canada, New England and the mid-Atlantic states have suffered poor air quality since June, with clouds of smoke carrying high levels of toxic air pollution reaching as far as Norway and the UK.
  • Many Indigenous communities lost their houses and their settlements 
  • Almost 23,000 Indigenous people have had to evacuate

Physical impact: torrential rain

  • 24 July: Three month’s worth of rain fell in a day in Nova Scotia - worst floods in Atlantic Canada in 50 years

Cascading/human impacts:

6 bridges destroyed, 19 damaged

For the past six weeks, a severe bushfire crisis has been dealt with by Canada, resulting in the widespread devastation of its forests and wildlife. These massive wildfires have triggered mass evacuations and have burned a staggering area of over 3.3 million acres.

This year, Canada has already experienced 2,214 fires, which together burned an area comparable to the size of Belgium. Disturbingly, projections indicate that the risk of wildfires will continue to increase in June and will remain alarmingly high through the summer season.

On July 17, several cities in the US elevated the levels on the Air Quality Index. For instance, the Air Quality Index in Cleveland reported 166 AQI. The health of individuals may suffer adverse consequences as any air quality reading above 150 AQI is considered unhealthy.

Myanmar hit by powerful Cyclone Mocha

Cyclone Mocha struck Myanmar's Rakhine State as one of the strongest cyclones ever recorded in the region. The devastating storm claimed the lives of approximately 145 people, destroyed critical infrastructure, and disrupted education for thousands of students.

According to the UN, the cyclone impacted 800,000 people overall. The education sector in the country has been significantly impacted by the storm, as approximately 80% of schools have suffered damage. This has resulted in disruptions to the scheduled start of the new school year, which was supposed to commence around the time the storm struck.

Torrential rains cause chaos in Italy

Italy's Emilia-Romagna region experienced torrential rainfall, leading to destructive flood and landslides that caused fatalities and displaced tens of thousands. The heavy rains wreaked havoc on farmlands and vital infrastructure, causing immense damage and disruption.

  • Heatwave ‘near impossible without climate change’
  • Hottest ever temperatures recorded in the Mediterranean sea: 28.4C, a month before usual temperature peaks.
  • 25 July: Palermo Observatory minimum temperature 36.2C, Palermo SIAS overnight Tmin (midnight-9am) 37.2C. Both are new European records.

  • 15 July: Red alerts issues to 16 cities across Italy

President of Emilia-Romagna, Stefano Bonaccini said of the situation: "There is no territory that can hold out when we experience six months of rain in 36 hours, falling where there had already been record rain two weeks ago."

Cascading/human impacts:

  • Three killed in fires in Sicily
  • Palermo airport closed, many roads closed due to fires.
  • Patients evacuated from a hospital in Palermo due to fires, amidst a rise in heat illnesses. Routine appointments suspended.
  • Fifteenth century church in Palermo affected by fire
  • Power cuts and water supply problems in Catania, Siclity
  • Cereal harvest is set to be the lowest since 2007, largely because of extreme heat in Portugal, Spain and Italy throughout July.
  • Catania in Sicily ‘brought to its knees’ by rolling power cuts due to heat damage to underground cables. This affected water pumps providing water to 200,000-300,000 people
  • The prolonged intensity of this heatwave and brutally hot tropical nights (20°C+) for millions across Southern Europe will build accumulating heat stress over the coming days that will not allow many to recover from the hot daytime temperatures, threatening public health and increasing the risk of heat illnesses. 
  • Additionally, a marine heatwave ongoing in the Mediterranean Sea intensifies the heat on land by increasing moisture levels in the air, making the extreme heat feel even more "humid," making heat-related deaths more likely due to the dangerous combo of heat and humidity.
  • Summer tourism numbers in the Mediterranean are falling, with significant implications for Italy’s GDP and economic growth.
  • German health minister says Italian tourism ‘has no future’ after suffering from the heatwave while visiting the country.
  • 44 year old man died while painting zebra crossings in Milan, 60 year old man died in his bakery in Padua.
  • More workers died - in supermarkets, on construction sites, on farms and more.
  • Visitors collapse in Rome.
  • Unions concerned for agricultural workers and construction workers
  • Hospitals report a 20-25% increase in numbers arriving at emergency units.
  • Healthcare under strain in Northern Hemisphere due to heat.
  • Record electricity consumption as people use airconditioning, leading to energy blackouts in Rome, Naples, Taranto and Bari - some metro stations suffered delayed opening in Rome on 19th July due to power cuts.
  • Heatwave plus the worst drought in 70 years are devastating olive oil production
  • Heatwaves in June and July are causing a poor tomato harvest. Milk production is estimated to have dropped by 10% because cows eat less in the heat, drink huge quantities of water and make less milk.
  • Cereal production in southern Europe is expected to fall by up to 60% compared to last year due to the summer heatwaves, and will likely be the lowest harvest since 2007. 
  • Car making factory stopped work due to heat while other workers went on strike due to dangerous hot conditions.
  • Farmworkers working 4am-11am
  • Possible landslides in glaciers

South Sudan's Fourth Year of Consecutive Flooding

South Sudan witnessed a historic fourth year of devastating floods, impacting around one million people and submerging vast regions of the country. With no sign of receding waters, basic necessities like food, water, and health care became difficult to access, leaving the country vulnerable to climate-induced displacements.

Mercy Gichuhi, Country Director for Mercy Corps in South Sudan, said: "floodwaters in Unity State have rendered all roads impassable, making basic necessities such as food, clean water, and health care, as well as life-saving humanitarian aid, difficult to access."

Worst Cyclone Freddy Sweeps Across Africa

Cyclone Freddy battered Malawi, Mozambique, Madagascar, and Zimbabwe, leaving behind a trail of destruction. The cyclone's intensity and longevity set new global records for accumulated cyclone energy. Public health concerns intensified as water and sanitation facilities were washed away.

The cyclone's intensity was so extreme that it shattered the global record for the highest accumulated cyclone energy and established a new record for the longest-lasting cyclone in recorded history. Apart from causing severe damage to infrastructure, the storm also washed away essential water and sanitation facilities.

As a result, there are significant public health concerns regarding the potential escalation of cholera spread, which was already a problem in Malawi prior to the cyclone's occurrence.

Deadly Heatwave sweeps across Asian Continent

Asia experienced a searing heatwave, shattering temperature records in more than a dozen countries. The extreme heat, described as the worst April heatwave in Asian history, impacted millions of lives, with school and business closures and reported deaths in India and Thailand. Climate experts warn that such heatwaves will increase in frequency and intensity across South Asia.

Maximiliano Herrera, a climatologist and weather historian, spoke to the Guardian and referred to the extreme heat as the "worst April heatwave in Asian history". The extreme heat is continuing in the country, resulting in the closure of schools and businesses to protect citizens from the heat, and there have been deaths reported in India and Thailand.

Deepshikha Sharma, a climate and environment specialist at the International Centre for Integrated Mountain Development (ICIMOD), asserted that human-induced climate change is primarily responsible for the increasing number and intensity of heatwaves observed in Asia. These heatwaves serve as a signal that the climate emergency has arrived for this region."

Chile Faces Decade-long Mega Drought

Chile suffered from an unprecedented "mega drought" that led to one of the deadliest wildfires in the nation's history. Intense summer temperatures and strong winds fueled the catastrophic blaze, leaving widespread destruction and loss of life. Authorities declared a state of emergency in three regions, emphasizing the urgent need to address climate change.

The flames engulfed an estimated 270,000 hectares (667,000 acres) of land, resulting in the destruction of numerous homes, the loss of 24 lives, and the declaration of a state of emergency in three regions. Chile's interior minister, Carolina Tohá, expressed astonishment at the unprecedented temperatures at the time, stating, "The thermometer has reached points that we have never known until now."

Winter storm creates chaos in southern-central US

An intense winter storm swept through the southern-central United States, leaving almost 40 million people under a weather alert. At least 10 people lost their lives, and widespread power outages and damages to homes disrupted daily life for hundreds of thousands.

Rain in São Paulo causes landslides

Brazil's São Paulo state faced torrential rainfall, triggering severe floods and landslides that claimed 48 lives and displaced 40,000 people. The region witnessed the highest cumulative rainfall ever recorded in the country, causing devastation to farmlands and critical infrastructure.
