The number of extremely hot days every year when the temperature reaches 50C has doubled since the 1980s, a global BBC analysis has found.

They also now happen in more areas of the world than before, presenting unprecedented challenges to human health and to how we live.

The total number of days above 50C (122F) has increased in each decade since 1980. On average, between 1980 and 2009, temperatures passed 50C about 14 days a year.

The number rose to 26 days a year between 2010 and 2019.

In the same period, temperatures of 45C and above occurred on average an extra two weeks a year.

“The increase can be 100% attributed to the burning of fossil fuels,” says Dr Friederike Otto, associate director of the Environmental Change Institute at the University of Oxford.

As the whole world warms, extreme temperatures become more likely.

High heat can be deadly for humans and nature, and cause major problems to buildings, roads and power systems.

Temperatures of 50C happen predominantly in the Middle East and Gulf regions.

And after record-breaking temperatures of 48.8C in Italy and 49.6C in Canada this summer, scientists have warned that days over 50C will happen elsewhere unless we cut fossil fuel emissions.

“We need to act quickly. The faster we cut our emissions, the better off we’ll all be,” says Dr Sihan Li, a climate researcher at the School of Geography and the Environment at the University of Oxford.

“With continued emissions and lack of action, not only will these extreme heat events become more severe and more frequent, but emergency response and recovery will become more challenging,” warns Dr Li.

The BBC analysis also found that in the most recent decade, maximum temperatures increased by 0.5C compared with the long-term average from 1980 to 2009.

But these increases have not been felt equally around the world: Eastern Europe, southern Africa and Brazil saw some maximum temperatures rise by more than 1C, and parts of the Arctic and Middle East recorded increases of more than 2C.

Scientists are calling for urgent action from world leaders at a UN summit in Glasgow in November, where governments will be asked to commit to new emissions cuts in order to limit global temperature rises.

Impacts of extreme heat

This BBC analysis launches a documentary series called Life at 50C investigating how extreme heat is affecting lives across the world.

Even below 50C, high temperatures and humidity can create severe health risks.

As many as 1.2 billion people around the world could face heat stress conditions by 2100 if current levels of global warming continue, according to a study from Rutgers University in the US published last year. That is at least four times more than those affected today.

People are also facing difficult choices as the landscape around them changes, as extreme heat makes drought and wildfires more likely. While, other factors can contribute, climate change is also an important driving force behind desertification.

Sheikh Kazem Al Kaabi is a wheat farmer from a village in central Iraq. The land around him was once fertile enough to sustain him and his neighbours, but it has gradually become dry and barren.

“All this land was green, but all of that is gone. Now it is a desert, drought.”

Almost all the people from his village have moved away to look for work in other provinces.

“I lost my brother, dear friends and loyal neighbours. They shared everything with me, even my laughter. Now nobody shares anything with me, I’m just face-to-face with this empty land.”

Methodology

It went over 50C in my area, why is it not featured?

Reports of record temperatures usually come from measurements taken at an individual weather station, but the data we have studied represents larger areas than those covered by a single station.

For example, Death Valley National Park in southern California is one of the hottest places on Earth. Temperatures in certain parts of the park regularly pass 50C in summer. But when creating an average for maximum temperatures for the wider area, using several different sources, a figure below 50C is reached.

Where is the data from?

The BBC has used the maximum daily temperatures from the high resolution global ERA5 dataset, produced by the Copernicus Climate Change Service. The data is often used to study global climate trends.

ERA5 combines actual weather observations from many sources, such as stations and satellites, with data from modern weather forecasting models.

The process fills in gaps created by poor station coverage in many parts of the world and helps us to understand climate change.

What analysis have we done?

Using the maximum temperature for every day from 1980 to 2020, we identified how often temperatures exceeded 50C.

We counted the number of days and locations with a maximum temperature of 50C or higher for every year, to determine the trend over time.

We also looked at the change in maximum temperatures. We did this by working out the difference between the average maximum temperature over land and sea for the most recent decade (2010-2019) compared with the 30 years before (1980-2009).

Averages of at least 30 consecutive years are known as climatologies. These are used for showing how recent periods compare to a climate average.

What do we mean by ‘location’?

Each location is roughly 25 sq km, or about 27-28 sq km at the equator. These grids can cover large areas and may contain many different types of landscape. The grids are squares of 0.25 degrees latitude by 0.25 degrees longitude.

Israel's war on Gaza: List of key events, day 101 | Israel War on Gaza News | Al Jazeera

Dozens of Palestinians killed in overnight Israeli strikes in central and south Gaza as Red Sea tensions rise.

Here’s how things stand on Monday, January 15, 2024:

Latest updates and human impact

  • Israeli attacks continue unabated overnight killing and wounding dozens of civilians in central and southern Gaza. At least 22 people were killed and a large number injured as a result of Israeli forces targeting al-Thalatheni Street in the central Gaza Strip.
  • Yemen’s Houthi rebels fired an antiship cruise missile toward an American destroyer in the Red Sea, which was shot down by a US fighter jet, announced US Central Command (CENTCOM) on X.
  • This was the first US-acknowledged Houthi attack since the US strikes on Yemen on Friday.
  • Hamas released a 37-second video showing three Israeli captives held in Gaza on Sunday, saying they would reveal the fate of the captives on Monday and urging the Israeli government to stop the offensive.
  • The Israeli military says it has shifted to a new phase of the war focused on the southern end of Gaza, where almost 2 million internally displaced Palestinians are running out of safe spaces to shelter.
  • The Gaza Ministry of Health has said almost 24,000 people have been killed in the Israeli offensive. More than 60,000 people have been wounded in 100 days of war.

Diplomacy

  • Israeli Prime Minister Benjamin Netanyahu said on Sunday that his country will pursue its war against Hamas until victory and will not be stopped by anyone, including the International Court of Justice (ICJ).
  • The White House said on Sunday that “it’s the right time” for Israel to scale back its military offensive in the Gaza Strip.
  • Egypt’s State Information Service (SIS) said in a statement on Sunday that one of the biggest obstacles to the timely delivery of sufficient aid to Gaza was Israeli inspection of the aid. The statement came after Israel blamed Cairo for the delay in aid delivery to Gaza during its defence at the ICJ.
  • US Secretary of State Antony Blinken posted on X on Monday, calling for the release of the remaining captives held in Gaza on the 100th day since they were taken by Hamas. He did not mention the Palestinian casualties.
  • Australia’s Foreign Minister Penny Wong, who described herself as a “friend of Israel” to the press, will travel to Jordan, Israel, the occupied Palestinian Territories and the United Arab Emirates this week, her office said on Monday.

West Bank raids and violence

  • Israeli forces arrested 25 students staging a sit-in in protest against high tuition fees at An-Najah University in Nablus. Al Jazeera’s Hamdah Salhut reported that the protesting students received a text message from Israeli forces telling them to “surrender now”.
  • Israeli forces have reportedly raided the family home of Nael al-Barghouti, the longest-serving Palestinian prisoner, in the village of Kobar, in Ramallah, in the occupied West Bank.
  • The Israeli army said on Friday that it killed three Palestinian men who infiltrated a West Bank settlement and fired upon soldiers.
  • The Israeli military killed two Palestinians after accusing them of ramming their car through a checkpoint near Hebron.
  • Local sources reported that Israeli forces bulldozed two Palestinian-owned houses during a Sunday midnight raid in the city of Qalqilya, Palestinian news agency Wafa reported.
  • Armed Israeli settlers broke into the village of Burin, south of Nablus, and attacked Palestinian residents’ houses and properties after midnight on Sunday, Wafa reported.
  • “Violent raids and arrests have become part of the fabric of daily life in the occupied West Bank,” Al Jazeera’s Mohammed Jamjoom, reporting from Ramallah in the occupied West Bank, said. At least 347 Palestinians have been killed and thousands have been arrested since October 7.

Hamas Says Will Kill Hostages if Israeli Attacks On Gaza Civilians Continue

Flames and smoke billow during Israeli attacks against Gaza on October 9, 2023

Human Rights Watch terms Israeli Defence Minister Yoav Gallant’s call for a ‘complete siege’ on Gaza a ‘war crime’.

The Hamas movement has threatened to kill an Israeli hostage every time Israel bombs a Palestinian home without warning as Israel mobilised some 300,000 reservists and imposed a total blockade of the Gaza Strip, denying the enclave’s millions of residents access to food, water and fuel.

The warning from Hamas came on Monday as the death toll from the armed group’s surprise weekend attack climbed to 900 in Israel and revenge attacks by Israeli forces on the besieged Gaza Strip killed more than 700 people and left some 3,700 others wounded.

Residential apartment blocks, hospitals, schools and a mosque have been among the sites attacked by Israeli fighter jets, artillery and drones, according to media reports and witnesses.

Hamas spokesperson Abu Ubaida issued the threat to kill Israelis from the dozens held captive by the armed group. He said an Israeli hostage would be killed for every Israeli bombing of a civilian house without warning.

Israeli Foreign Minister Eli Cohen said more than 100 people were taken captive by Hamas during the deadly cross-border incursion over the weekend.

As Israeli forces conducted intense retaliatory attacks on Gaza on Monday, Israel’s Defence Minister Yoav Gallant drew international condemnation by announcing a total blockade of the densely populated and besieged enclave, which is home to 2.3 million people.

Gallant said Israel would impose a “complete siege” on Gaza. “No electricity, no food, no water, no gas – it’s all closed.”

United Nations Secretary-General Antonio Guterres said he was “deeply distressed” by the siege announcement and warned that Gaza’s already dire humanitarian situation will now “only deteriorate exponentially”.

Guterres also said some 137,000 people were taking shelter with the UN Relief and Works Agency for Palestinian Refugees (UNRWA) at schools across Gaza.

UNRWA said on Tuesday that almost 190,000 people have been displaced in Gaza amid the Israeli attacks and the figure is expected to grow further as the violence intensifies.

Nearly half a million people have also not received food rations this week in Gaza as UN food distribution centres have been forced to remain closed amid the Israeli onslaught, UNRWA said.

Human Rights Watch said Israel’s total blockade on the necessities of life for everyday people in Gaza was a war crime.

“Defense Minister Gallant’s statements are abhorrent,” Omar Shakir, Israel and Palestine director at Human Rights Watch, said in a statement.

“Depriving the population in an occupied territory of food and electricity is collective punishment, which is a war crime, as is using starvation as a weapon of war. The International Criminal Court should take note of this call to commit a war crime,” he said.

Shakir also condemned the threat by Hamas to kill hostages, warning that such action was also a war crime.

“All hostages should be safely released to their families,” he said.

On the diplomatic front, Egyptian President Abdel Fattah el-Sisi and his Turkish counterpart Recep Tayyip Erdogan called on Hamas and Israel to immediately end violence and protect civilians, the Egyptian presidency said.

Erdogan urged Israel against “indiscriminately” attacking civilians and delivered measured criticism of Hamas, urging both sides to respect the “ethics” of war.

The United Kingdom, French, German, Italian and US governments issued a joint statement on Monday recognising the “legitimate aspirations” of the Palestinian people and supporting equal measures of justice and freedom for Israelis and Palestinians alike.

They said they would remain “united and coordinated” to ensure Israel can defend itself.

But the prospect that fighting could spread also alarmed the region and the world.

Lebanese armed group Hezbollah fired rockets into northern Israel in response to at least three of its members being killed in Israeli shelling of Lebanon.

Israel said one of its deputy commanders was also killed in an earlier cross-border raid from Lebanon.

Western Leaders Accused of Hypocrisy Over Response To Palestine, Ukraine

US President Joe Biden holds a bilateral meeting with Israeli Prime Minister Benjamin Netanyahu on the sidelines of the 78th United Nations General Assembly in New York City, the US, September 20, 2023

Social media users, including journalists and observers, are calling out what they call a ‘double standard’.

After Saturday’s surprise attack by the Palestinian group Hamas on Israel, Ukrainian President Volodymyr Zelenskyy took to the social media platform X to offer “condolences go out to everyone who lost relatives or close ones in the terrorist attack”.

He also stated, “Israel’s right to self-defence is unquestionable.”

Many world leaders, including US President Joe Biden and UK Prime Minister Rishi Sunak, shared similar sentiments.

European Commission President Ursula von der Leyen stated, “Israel has the right to defend itself – today and in the days to come. The European Union stands with Israel.”

Accusations of Western ‘double standards’

Some social media users have criticised these statements, saying they highlight a double standard.

Ukraine’s right to defend itself is praised by most international leaders while Russia’s invasion is condemned, but commentators said the same cannot be said about Israel’s occupation of the West Bank and Gaza.

Aaron Bastani, a leftist British journalist, said on X that there’s a “clear double standard in endorsing terrorism against civilian targets in Ukraine … and condemning it by Palestinians”.

Many users said Western diplomats and media support the Ukrainians who defend their land, but label the Palestinians fighting against Israel as “terrorists”.

An illustration of a woman’s face, in which one eye is closed beside a Palestinian flag, and one eye open beside a Ukrainian flag, has been regularly shared as a symbol of the West’s alleged double standards in how the two conflicts are viewed.

https://twitter.com/OnlinePalEng/status/1710994682883273172?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1710994682883273172%7Ctwgr%5E6acf829869e993177f32aa38aa48c02f38cb7f61%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fwww.aljazeera.com%2Fnews%2F2023%2F10%2F9%2Fwestern-leaders-accused-of-hypocrisy-over-response-to-palestine-ukraine

Clips also emerged on social media from a CNN interview with Mustafa Barghouti, the general secretary of the Palestinian National Initiative, in which he posed the rhetorical question, “Why does the United States support Ukraine in fighting occupation – while here they support the occupier, who continues to occupy us?”

It is not the first time Western nations have been accused of double standards in their stance on the Ukraine war.

Earlier in the year, Amnesty International published a report highlighting the West’s “double standards” on global human rights.

Agnes Callamard, Amnesty’s secretary-general, told Al Jazeera at the time that the occupation of Palestinian territory was a “particularly important one”.

“Without making any comparison between Russia’s aggression and Israel … it is clear the Palestinian people are under a regime of oppression – a regime of occupation and a regime of apartheid,” Callamard told Al Jazeera.

Over the last three days, X users recirculated earlier statements calling out what they called Western hypocrisy, sharing video by the Irish lawmaker Richard Boyd Barrett from March 2022 in which he berated the Irish government’s double standards regarding Ukraine and Palestine:

“You’re happy to use the most strong and robust language to describe the crimes against humanity of [Russian President] Vladimir Putin, but you will not use the same strength of language when it comes to describing Israel’s treatment of the Palestinians.”

Barrett on Sunday again called out what he described as “shocking double standards of Western leaders supporting Ukraine resistance but condemning Palestinian[s].”

Meanwhile, others warned against comparing conflicts.

https://twitter.com/denfordauthor/status/1710993737738768607?ref_src=twsrc%5Etfw%7Ctwcamp%5Etweetembed%7Ctwterm%5E1710993737738768607%7Ctwgr%5E6acf829869e993177f32aa38aa48c02f38cb7f61%7Ctwcon%5Es1_&ref_url=https%3A%2F%2Fwww.aljazeera.com%2Fnews%2F2023%2F10%2F9%2Fwestern-leaders-accused-of-hypocrisy-over-response-to-palestine-ukraine

And some cautioned that Hamas and the Palestinians should not be seen as one and the same.

Ukrainian footballer Oleksandr Zinchenko, who plays for Arsenal, posted on Instagram, stating he “stands with Israel”.

Zinchenko has been a vocal supporter of his home country in its ongoing defence against Russia, and he participated in a Game4Ukraine charity match in London earlier this year to raise money for Ukraine.

After online backlash, with some questioning an alleged double standard in his support of Israel, the footballer removed the post and switched his social media account to private.

Several people claimed that Zinchenko’s football club, in not responding to his comments, was guilty of hypocrisy after they had distanced themselves from former player Mesut Ozil’s comments in 2019 over alleged human rights abuses against Uighur Muslims in China.
