How Hot Is It Today?

What is the hottest temperature on Earth now?

Highest temperatures ever recorded – Currently, the highest officially registered temperature is 56.7C (134F), recorded in California’s Death Valley back in 1913. The hottest known temperature in Africa is 55C (131F), recorded in Kebili, Tunisia in 1931.

  1. Iran holds the record for Asia’s hottest official temperature of 54C (129F), which it recorded in 2017.
  2. The highest temperature ever recorded in Europe was 48.8C (119.8F) on the Italian island of Sicily on August 11, 2021.
  3. On July 19, 2022, The United Kingdom recorded its highest-ever temperature, reaching 40.2C (104.4F), according to its Meteorological Office.

In 2020, Seymour Island in Antarctica recorded a maximum temperature of 20.7C (69.3F). According to the United Nations’ World Meteorological Organization (WMO), temperatures on the Antarctic Peninsula have risen by nearly 3C (5.4F) over the past 50 years. (Al Jazeera)

Where is it hottest now?

The UK may be experiencing an unusually fresh July, but around the world extreme heat is wreaking havoc. Last week, the Cerberus heatwave saw popular British holiday hotspots in the Mediterranean from the Spanish islands to northern Italy to the Greek capital surpass 40C (104F).

  • Since then, a heat dome has settled over the American southwest imposing extreme heat warnings for over 113 million people and China recorded its highest-ever temperature.
  • As the European Centre for Medium-Range Weather Forecasts says this June was the hottest ever, and freak weather events such as Canada’s unprecedented wildfires and South Korea’s flooding continue to claim lives, scientists are ringing climate change alarm bells louder than ever.

This week, a new anticyclone – dubbed Charon – is set to make its way up from North Africa to Europe and push the mercury well beyond 45C (113F). The Italian Meteorological Service has warned temperatures could reach up to 49C (118F) in Sardinia this week – potentially surpassing Europe’s record high of 48.8C (120F) in Sicily in August 2021.

  1. Rome is also set to shatter its previous record with an expected high of 43C (109F).
  2. On Friday, authorities in Greece closed the Acropolis and first-aid workers were brought in as the capital writhed under 42C (108F) heat.
  3. In Greek mythology, Charon is the ferryman of the dead.
  4. The interior of the Spanish island of Mallorca has been placed on red alert, with one weather agency forecasting 44C on Tuesday.

On the Canary island of La Palma, more than 4,000 people were evacuated from their homes last week as a forest fire ripped through dried-out woodland. A similar story played out in Turkey over the weekend, where 19 fires broke out with 24 hours in the southern regions.

The coastal resort of Antalya broke 44C (111F) last week, and is set to post readings of up to 42C (108F) on Monday, according to global forecaster Ventusky. California’s aptly named Death Valley is the location of the hottest temperature ever reliably recorded on Earth – 56.7C (134F). The US National Weather Service (NWS) said the gauge reached 53.9C there on Sunday.

Temperature records could be broken this week in as many as 38 cities. Las Vegas’s 47C (117F) high-watermark is likely to be breached within the next few days, with 48C (115F) posted in nearby Phoenix, Arizona, on Saturday. A second firefighter has also died in Canada, where nearly 900 wildfires are currently burning.

The UK Met Office has said Sanbao in China’s western Xinjiang region has just posted the country’s highest-ever temperature – a sweltering 52C (126F). As a result of surging air-conditioning use over the past week, a major generator declared its electricity output hit a record high on Monday. Despite being spared from hotter than average temperatures, some of the world’s long-time hottest cities are also baking this summer.

Kuwait City, where thermometers crept above 52C back in 2021, is currently a sweltering 47C. The Saudi Arabian capital of Riyadh is at 45C (113F). The city of Kebili, in Tunisia, is the site of the disputed 55C (131F) African temperature record set in 1931.

  • Its residents are currently toasting in 46C heat.
  • The Met Office has watered down fears of heatwaves reaching the UK, but that doesn’t mean the country will be spared for long.
  • This time last year we saw temperatures above 40C for the first time in the country’s history, as the UK Health Security Agency (UKHSA) issued a Level 4 alert for the first time since their Heatwave Plan for England was introduced in 2004.

A record 40.3C (105F) was seen in Coningsby, Lincolnshire last July 19, with Wales and Scotland also posting their highest-ever readings around that time. According to the Royal Meteorological Society’s State of the UK Climate 2020 report, all of the top 10 warmest years for the UK since 1884 have occurred since 2002.

What is the temperature in Antarctica?

Can humans survive 50 degrees Celsius?

Human beings can survive at 50 degrees Celsius. They can not do this if there is no food or water. Also, if they are in direct sunlight, they would probably not survive for a few days, due to the effects of severe sunburn.

How hot can humans survive?

How hot is too hot for survival? Researchers cranked up the temperature on volunteers to find out. A new study suggests that once temperatures hit 104 to 122 degrees, our bodies may stop working optimally.

What is the 1 hottest city in the world?

Dallol, Ethiopia In terms of extreme heat, no place holds a candle to Dallol, the hottest place on earth. Located in the sizzling Danakil Depression (a geological landform sunken below the surrounding area), it can reach a boiling 145 degrees in the sun.

Why is Death Valley so hot?

July 19, 2023 / 1:44 PM / MoneyWatch One of hottest places on Earth is drawing more visitors this week, not in spite of near-record high temperatures but because of them. Tourists are flocking to Death Valley National Park — a narrow, 282-foot basin on the California-Nevada border — to experience how the triple-digit temperatures feel against their skin.

  • Death Valley is home to Furnace Creek, an unincorporated community that includes a visitors center and an outdoor digital thermometer.
  • Dozens of people have gathered at the temperature reading in recent days, some wearing fur coats as an ironic joke, to experience the heat and snap a picture to impress family and friends on social media.

“I just want to go to a place, sort of like Mount Everest, to say, you know, you did it,” William Cadwallader of Las Vegas told the Associated Press this week, adding that he visits Death Valley regularly. People visit the unofficial thermometer reading 133 degrees at Furnace Creek Visitor Center on July 11, 2021 in Death Valley National Park, California. Getty Images The tourism uptick started late last week and reached an inflection point Sunday when Death Valley reached 128 degrees Fahrenheit, just seven degrees shy of the highest temperature recorded on Earth — 134 degrees Fahrenheit at Furnace Creek on July 1913.

  • Death Valley is situated below sea level but is nestled among steep mountain ranges, according to the park service’s website.
  • The bone-dry air and meager plant coverage allows sunlight to heat up the desert surface.
  • The rocks and the soil emit all that heat in turn, which then becomes trapped in the depths of the valley.

Doctors urge caution with 90 million Americans under extreme heat warnings Nearly 20 million people across U.S. under heat alerts

“I was really noticing, you know, I didn’t feel so hot, but my body was working really hard to cool myself,” Jusehus said. Death Valley’s brutal temperatures come amid a blistering stretch of hot weather that’s put roughly one-third of Americans under a heat advisory, watch or warning.

  • Heat waves aren’t as visually dramatic as other natural disasters, but experts say they’re more deadly.
  • A heat wave in parts of the South and Midwest killed more than a dozen people last month.

Words by Nina Gallo, Aurora Expeditions’ historian and certified PTGA polar guide. Nina has been drawn to the polar regions since her first otherworldly experience of the midnight sun in 2002. Since then she has spent time in far northern Canada, the Himalayas, the Alps and deserts in America and Australia, always seeking out quiet, wild corners to explore.

Does it ever rain in Antarctica?

Precipitation – The dry, subsiding air over the interior of Antarctica creates little cloud. Around the coast however, more moisture is available and low-pressure systems have a greater influence. This means that cloudy conditions more common near the coast, particularly on the Antarctic Peninsula.

  1. Rain is observed near the coast, but most precipitation over Antarctica is in the form of snow or ice crystals.
  2. Windy conditions make it difficult to measure snowfall accurately.
  3. The average accumulation of snow over the whole continent is estimated to be equivalent to about 150 mm of water per year.
  4. Over the elevated plateau, the annual value is less than 50 mm.

Near the coast, it generally exceeds 200 mm, the heaviest being over 1,000 mm for an area near the Bellingshausen Sea.

What is the coldest city in Russia?

Commuters behind frozen bus windows in Yakutsk, known as the coldest city in the world Mladen Antonov / AFP via Getty Images Wake up and start layering on multiple hats, scarves and mittens. Go outside to check on the car that’s been running all night, because turning it off could cause the engine to freeze.

Visibility is poor because the city is shrouded in ” ice fog “—a thick mist that forms when the temperature is too cold for hot air to rise. Welcome to winter in Yakutsk, the coldest city in the world, Residents of this notoriously frosty city, the capital of Russia’s Sakha Republic in eastern Siberia, regularly deal with temperatures as low as minus 40 degrees Fahrenheit in the winter.

But last week, temperatures plunged to minus 80.9 degrees—the coldest in more than two decades, reports CNN ‘s Heather Chen. The air in Yakutsk is often cold enough to make exposed skin go numb, which, if unnoticed, can lead to frostbite. But even so, some locals seem unfazed. Villagers harvest ice from a local lake near the settlement of Oy, some 40 miles south of Yakutsk. Mladen Antonov / AFP via Getty Images More than 300,000 people live and work in Yakutsk, which is one of Siberia’s fastest growing regional cities, despite its cold temperatures and far-flung location, 3,100 miles from Moscow.

  1. Located on the Lena River, Yakutsk is a mining city—and wages can sometimes be higher there, a payoff for the harsh climate.
  2. It also attracts adventurous tourists intrigued by the city’s frosty reputation.
  3. Another resident, Nurgusun Starostina, sells frozen fish at an outdoor market—and she doesn’t even need to use a freezer.

“Just dress warmly,” she tells Reuters. “In layers, like a cabbage!” Yakutsk’s other claims to fame? It’s a great place to learn about the Ice Age—specifically, the woolly mammoth. The city houses the Mammoth Museum, where visitors can view woolly mammoth fossils, and the Melnikov Permafrost Institute’s Underground Laboratory, which has a tunnel showcasing fossils in below-freezing temperatures.

  1. The city is built on a continuous permafrost, meaning that a layer of frozen soil is present even in the summer.
  2. Many buildings are constructed on stilts because of these conditions, which can threaten structures’ foundations when the frost starts to thaw,
  3. Life in the freezing city may be difficult, especially when temperatures break records, but many have found ways to adapt.

That’s doubly true for the smaller villages outside the city, like Oymyakon, a rural locality in the Sakha Republic. “A guy I was staying with left his car running all night, but even so, in the morning, the drive shaft was completely frozen,” photographer Amos Chapple recounted to Smithsonian magazine ‘s Natasha Geiling in 2015.

Is Moscow colder than Siberia?

– When people imagine Russia they, more often than not, picture snow and to some people visiting Russia in winter is what Russia is all about. It is true that Russia can be a beautiful winter wonderland, but travelling in winter does of course have its draw backs and difficulties. Russia is very well prepared for this and the public transport system is very well geared up for snow and there are not usually delays due to the winter weather. In Moscow there is a whole army of street cleaners who remove the snow from the paths. However no matter how good the cleaners are the hazard of icy streets always remains. Winter temperatures vary depending on where you are in the country. It is much milder in Moscow and St Petersburg, although even here it is not unusual for the temperature to fall to -20 and below in late January. Of course when we say ‘much milder’ we mean in comparison to Siberia where -40 to -50 is not unheard of in some cities such as Yakutsk. The average winter temperature in Novosibirsk in Siberia is -20 but that can be completely bearable if you have the right clothes. Plus winter weather in the capitals often brings grey clouds with milder temperatures, whereas freezing Siberia in winter still often has clear blue skies.

Can humans survive 1000 degrees Celsius?

New Delhi, UPDATED: Jul 5, 2021 13:26 IST Normal human body temperature is 98.6-degree Fahrenheit which corresponds to 37-degree Celsius. Anything above is called fever, which can lead to hyperthermia in a heat wave condition. It could be fatal. It is commonly held that the maximum temperature at which humans can survive is 108.14-degree Fahrenheit or 42.3-degree Celsius.

Can humans survive 300 degrees?

Though humans are adaptable and able to survive a wide range of conditions and circumstances, there is still a limit to human survival. Many of the boundaries within which a typical human can survive have been fully established, while others are just speculative because people rarely, if ever, test them.

  1. Experiments, whether intentional or accidental, have helped scientists understand what the human body is capable of surviving.
  2. But even with some established limits, there have also been some extraordinary exceptions to rules.
  3. Here’s a closer look into the limits of survival.
  4. Coldest temperature The coldest temperature humans can survive comes down to our core temperature rather than the temperature outside.

The human body is designed to displace heat rather than retain it. When the body loses heat faster than it can make it, the core temperature starts to reduce. The average body temperature is 98.6 degrees Fahrenheit. At an internal temperature of 95 degrees, humans can experience hypothermia, shivering and pale skin.

At 86 degrees, they become unconscious and, at 77 degrees, cardiac arrest can occur. Most people cannot survive if their core temperature drops to 75 degrees, However, the length of time each person could sustain this varies depending on how adapted they are to the cold. A mysterious, latent form of hibernation could also set in, which has been known to save people from freezing.

If the temperature outside reaches -40 degrees, most humans would die within 10 minutes of exposure. Since water call pull heat from the body more rapidly than air, a person would last barely 30 minutes in 40-degree water, Hottest temperature Humans are well adapted to hot climates, but the amount of external heat we can survive depends on a person’s individual physiology, exertion and hydration.

The humidity of the air also plays a factor as it slows or stops our sweat from evaporating, which makes us even hotter. Most humans will suffer hyperthermia after 10 minutes in extremely humid 140 -degree heat. In this environment, our body temperature could be raised to 104 degrees or above, and we will experience heatstroke, trouble breathing and organ failure.

Death Valley, one of the hottest places on Earth, recorded a temperature of 130 degrees last month. In most cases, once a person’s core temperature reaches 107.6 degrees, the heatstroke cannot be reversed and will be fatal. If the humidity is low, humans can endure even hotter temperatures.

  • In a burning building or a deep mine, adults have survived 10 minutes at 300 degrees.
  • Children, however, cannot withstand such temperatures, and 120-degree cars can be deadly in just minutes.
  • Holding your breath Most people find it difficult to hold their breath for more than a minute.
  • Holding your breath for too long can cause heart problems and brain damage.

If 2 minutes pass, people could enter a deep coma and, at the 3-minute mark, they would likely die. However, humans can hold their breath much longer if they are underwater. Swimming activates the “diving reflex,” which slows the heart rate and metabolism.

  • There is a technique that free divers use called static apnea.
  • This process involves holding your breath face down in chilled water without moving.
  • With training, people can hold their breath for around 11 minutes underwater.
  • Trained breath holders hyperventilate before holding their breath to clear their body of carbon dioxide.

By taking a breath of pure oxygen, people have nearly doubled their time. In 2016, Aleix Segura Vendrell set the Guinness World Record by holding his breath for 24 minutes and 3 seconds. Deepest dive and highest climb The increased pressure deep underwater is dangerous to humans.

  • It allows more oxygen and nitrogen into the blood, which can make divers dizzy or tired.
  • It can also alter their decision-making ability.
  • Scientists have yet to determine the exact limit for how deep humans can survive underwater, but if they go too deep, their lungs would eventually collapse.
  • Most professional scuba divers don’t dive beyond 400 feet.

But the record for the deepest scuba dive is 1,090 feet and 4.5 inches, When considering heights, humans pass out when the pressure drops below 57% of atmospheric pressure. This happens at an altitude of 15,000 feet, Climbers, however, are able to continue higher because they gradually acclimate their bodies to the drop in oxygen.

Raised red blood cell counts and enlarged lungs are common to those who live in higher altitudes. However, without an oxygen tank, humans cannot survive long above 26,000 feet. That is about 5 miles high. Longest without food The standard limit a person can last without food is about 45 days if they are hydrated.

But the amount of time is affected by body weight, composition, genetic variations and other health considerations. The chances of surviving longer without food are higher if the person’s body weight is higher. During a study published in 1973, Angus Barbieri, who weighed 456 pounds, was monitored while he fasted down to 180 pounds.

He went without food for 382 days, while consuming only zero-calorie drinks and vitamins. The water-soluble B vitamins made it possible for him to survive by helping metabolize the fat stored in the body. Without these, it would be possible for someone overweight to die of starvation. If a person loses 30% of their body weight, they usually won’t survive.

But with such rapid weight loss, a person is more likely to die from disease before starvation. Longest without water Every cell in a person’s body needs water. The longest a person can go without water varies depending on their situation. If someone was doing strenuous exercise on a hot day, then they could be losing 1.5 liters of water per hour.

If they don’t rehydrate, their blood pressure would drop and their heart rate would increase. Sweating would stop, which would make them even hotter. In this case, the person wouldn’t survive past a few hours. Alternatively, in a cool environment with little exertion, a person could survive around one week without rehydrating.

But as a general rule, in a normal environment, people can survive 3-4 days without water. Longest without sleep Sleep is essential for survival. Psychology professor Stanley Coren said, “When sleep deprivation becomes great enough, the effects mimic those of psychosis.” Even a single all-nighter impairs driving abilities as much as being drunk.

  • Continued lack of sleep can cause hallucinations and a drop in body temperature.
  • The longest anyone has voluntarily stayed awake before nodding off is 264 hours or about 11 days,
  • This record was set by 17-year-old Randy Gardner for a high school science fair project in 1964.
  • Since then, records have eliminated the category of going without sleep because of the health dangers.

In 2012, a 26-year-old man reportedly died 11 days into a sleepless attempt to watch every game of the European Cup. But he was also drinking alcohol and smoking throughout, making it difficult to determine his cause of death. No human has ever definitively died from lack of sleep alone.

  1. Based on experiments on rats, scientists believe humans could go about 14 days without sleep before dying, though there is no way to know for sure.
  2. Oldest age The limit to how long humans can live is a controversial topic.
  3. Some scientists believe there is a fixed age that humans can’t go beyond, while others believe if there is a maximum limit, humans aren’t close to it yet.

The current record holder for oldest age is Jeanne Calment who died at the age of 122 years and 5 months, Increasing lifespans have been observed in many countries since the 1950s. One expert claims that the maximum age slowed in the 1980s and has now stopped with the upper age limit at 115 years old, though there is the occasional anomaly.

  • This claim sparked debate in the scientific community.
  • A recent study found that as long as you reach the age of 105, the risk of dying plateaus.
  • This would mean that someone who is 50 is 3 times more likely to die within the next year than someone who is 30.
  • But someone who is 105 has the same likelihood of dying in the next year as someone who is 120.

The chances of dying would no longer increase. Some believe this is because we aren’t close to the maximum limit, while others believe it is because of “survival of the fittest.” Exceptions Some survivors have gone well beyond the normal rule of human limitations.

Coldest temperature: In 1999, skier Anna Bågenholm fell through a sheet of ice and was dragged underneath by a stream. She found an air pocket large enough to let her breathe, but she was trapped under 8 inches of ice for about 80 minutes. This caused her body temperature to drop down to 56.7 degrees,

She experienced cardiac arrest, but she didn’t die. Before the freezing temperatures stopped Bågenholm’s heart, the constant flow of ice water had chilled and preserved her brain and vital organs. This delayed her cells from dying. Though she was clinically dead for more than two hours, medical personnel were able to revive her.

Not only did Bågenholm recover, but the results of her survival went on to change medical practices. Therapeutic hypothermia was introduced: The body is cooled down to induce hypothermia to protect patients during open heart surgery as well as victims of strokes, seizures and liver failure. Still, 56.7 degrees is the coldest anyone has ever been and survived.

Hottest temperature: Willie Jones holds the record for the highest recorded body temperature. During an Atlanta heat wave in 1980, Jones was admitted to the hospital with heatstroke and a temperature of 115.7 degrees, He spent 24 days in the hospital and survived.

How hot is unsafe?

What is the heat index?

“It’s not the heat, it’s the humidity”. That’s a partly valid phrase you may have heard in the summer, but it’s actually both. The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This has important considerations for the human body’s comfort. When the body gets too hot, it begins to perspire or sweat to cool itself off. If the perspiration is not able to evaporate, the body cannot regulate its temperature. Evaporation is a cooling process. When perspiration is evaporated off the body, it effectively reduces the body’s temperature. When the atmospheric moisture content (i.e. relative humidity) is high, the rate of evaporation from the body decreases. In other words, the human body feels warmer in humid conditions. The opposite is true when the relative humidity decreases because the rate of perspiration increases. The body actually feels cooler in arid conditions. There is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

Figure 1. Heat index chart. In order to determine the heat index using the chart above, you need to know the air temperature and the relative humidity. For example, if the air temperature is 100 ° F and the relative humidity is 55%, the heat index will be 124 ° F. When the relative humidity is low, the apparent temperature can actually be lower than the air temperature. For example, if the air temperature is 100 ° F and the relative humidity is 15%, the heat index is 96 ° F (). In the Panhandles, we commonly see hot temperatures during the summer, but the low relative humidity values make it somewhat unusual to see dangerous heat index values (i.e.103 ° F or greater). A full heat index chart for a larger range of temperatures and relative humidity values can be found,

It surprises many people to learn that the heat index values in the chart above are for shady locations. If you are exposed to direct sunlight, the heat index value can be increased by up to 15°F. As shown in the table below, heat indices meeting or exceeding 103 ° F can lead to dangerous heat disorders with prolonged exposure and/or physical activity in the heat.

Classification Heat Index Effect on the body
Caution 80°F – 90°F Fatigue possible with prolonged exposure and/or physical activity
Extreme Caution 90°F – 103°F Heat stroke, heat cramps, or heat exhaustion possible with prolonged exposure and/or physical activity
Danger 103°F – 124°F Heat cramps or heat exhaustion likely, and heat stroke possible with prolonged exposure and/or physical activity
Extreme Danger 125°F or higher Heat stroke highly likely

Use this if you prefer to enter numbers manually instead of reading a chart. If you’re really mathematically inclined, there is an equation that gives a very close approximation to the heat index. However, this equation was obtained using a multiple regression analysis, and therefore, it has an error of ±1.3 ° F.

How hot is too hot inside?

Best House Temperature While Away: 55–80 degrees – When you’re away from your home, it’s possible to decrease your energy consumption by dialing down the heat or air conditioning. While away from the home, homeowners will reduce their energy use by increasing home temperature in summer and decreasing it in winter.

In general, it’s safe to increase indoor temperature up to 80 degrees in summer and decrease indoor air temperature to 55 degrees in winter, but there are exceptions – for example, if you live with a baby or an elderly or immune-compromised individual. These temperature swings are large enough to make an impact on your energy bill, and small enough for your HVAC system to return to ideal temperatures relatively quickly when you return home.

Be careful not to decrease your home’s temperature to less than 55 degrees in winter or allow your home to warm to more than 80 degrees in summer, as it may leave your home susceptible to damage. An indoor temperature of less than 55 degrees may lead to freezing pipes, while anything more than 80 may damage drywall.

How hot is uncomfortable?

85 degrees may make some people feel hot while for others it might be 90 or 95. Various studies have shown the ‘ideal’ temperature for humans to feel most comfortable is 72 degrees.

Is July 4 2023 the hottest day on Earth?

While July 4 is usually hot for much of the U.S., the entire globe was toastier than usual on Tuesday. Monday and Tuesday were the two hottest days on record since at least 1979, according to data from the U.S. National Centers for Environmental Prediction.

  • So how hot was it Monday and Tuesday? July 4, 2023 was the hottest day on Earth since records began in 1979.
  • The average global temperature reached 17.18 degrees Celsius (62.92 degrees Fahrenheit) Tuesday, surpassing the previous record of 17.01 degrees Celsius (62.62 degrees Fahrenheit) set on Monday, July 3, 2023.

The previous record was 16.92 degrees Celsius (62.46 degrees Fahrenheit) set on August 14, 2016. It’s important to note that the hottest day on Earth is not the same as the hottest temperature ever recorded on Earth. The hottest temperature ever recorded on Earth was 134 degrees Fahrenheit (56.7 degrees Celsius), which occurred in Death Valley, California in 1913.

While it was record-breaking heat in Death Valley, the average global temperature was much cooler on that day. The average global daily temperature is compiled using data from the U.S. National Centers for Environmental Prediction and the University of Maine. This specific data set goes back to 1979, when satellite temperature monitoring began.

Monday marked the first day that global temperatures averaged above 17 degrees Celsius. These abnormally warm global temperatures are due to the combination of human-induced climate change and El Niño. El Niño is a natural climate pattern that causes the Pacific Ocean to warm, which in turn leads to warmer temperatures around the world. More on this year’s El Nino pattern read more While Monday and Tuesday were record-breaking, it’s possible to see even warmer global average temperatures as we head into the remainder of the summer months in the Northern Hemisphere.

What is the hottest day of 2023?

Monday was hottest day for global average temperature on record, as climate crisis bites This Monday, 3 July 2023, was the hottest day ever recorded globally, according to data from the US National Centers for Environmental Prediction. The average global temperature reached 17.01C (62.62F), surpassing the August 2016 record of 16.92C (62.46F), as heatwaves sizzled around the world.

The southern US has under an in recent weeks amid, probably driven by the human-caused climate crisis,, In parts of China, an continued, with temperatures above 35C (95F). North Africa has seen temperatures near 50C (122F), with, in the Middle East, from unusually scorching heat during the hajj religious pilgrimage in Saudi Arabia.

And even, currently in its winter, registered anomalously high temperatures, as accelerates and the sun intensifies. Ukraine’s Vernadsky research base, in the vast frozen continent’s Argentine Islands, recently broke its July temperature record with a reading of 8.7C (47.6F).

  1. Jeni Miller, executive director of the California-based Global Climate and Health Alliance, an international consortium of health organizations, said: “People around the world are already enduring climate impacts, from heatwaves, wildfires and air pollution to floods and extreme storms.
  2. Global warming is also exacerbating crop losses and the spread of infectious diseases, as well as migration.” She added: “The extraction and use of coal, oil and gas harm people’s health, are the primary driver of warming and are incompatible with a healthy climate future.

That’s all the more reason that governments must prepare to deliver a commitment at to phase out all fossil fuels, and a just transition to renewable energy for all.” The climate scientist Friederike Otto of the Grantham Institute for Climate Change and the Environment at Britain’s Imperial College London, said: “It’s a death sentence for people and ecosystems.” Scientists lamented the climate crisis, accelerated by the, the latest of which the United Nations’ World Meteorological Organization (WMO) warned this week had begun.

What is the hottest day on Earth 2023?

The planetary average temperature hit 63 degrees Fahrenheit (17.23 degrees Celsius) Thursday, surpassing the 62.9-degree mark (17.18-degree mark) set Tuesday and equaled Wednesday, according to data from the University of Maine’s Climate Reanalyzer, a tool that uses satellite data and computer simulations to measure the world’s condition.

The average global air temperature is recorded two meters above the Earth’s surface at various locations with the data compiled by the National Oceanic and Atmospheric Administration (NOAA) and the University of Maine, That average includes places that are sweltering under dangerous heat — like Jingxing, China, which checked in almost 110 degrees Fahrenheit (43.3 degrees Celsius) — and the merely unusually warm, like Antarctica, where temperatures across much of the continent were as much as 8 degrees Fahrenheit (4.5 degrees Celsius) above normal this week.

Prior to this week, the previous record for the Earth’s hottest day was set in July 2022 and in August 2016 when the global temperature reached 62.46 degrees. The rise in global temperatures is likely due to recent heat waves in the US, Canada and Europe and El Nino. NOAA on Thursday issued a note of caution about the Maine tool’s findings, saying it could not confirm data that results in part from computer modeling. “Although NOAA cannot validate the methodology or conclusion of the University of Maine analysis, we recognize that we are in a warm period due to climate change,” NOAA said.
