Climate change: July set to be world's warmest month on record

Amid blistering heatwaves, July is "virtually certain" to be the world's warmest month on record, say scientists.

So hot has the month been to date that researchers are confident the 2019 record will be broken, even with several days to go.

...

Some experts believe that July might well be the warmest month in the past 120,000 years.

Researchers are not surprised that July is set to break the current record for the warmest month as there have been plenty of indications in recent weeks that the world is seeing far greater levels of heating.

The world's warmest day occurred on July 6, and the hottest 23 days ever recorded were all this month, according to the Copernicus Climate Change Service.

Their provisional average temperature for the first 25 days of the month is 16.95C, which is well above the 16.63C figure for the whole of July 2019.

Other analysis has come to the same conclusion.

Dr Karsten Haustein from the University of Leipzig has calculated that July 2023 will be 1.3C-1.7C above the average July temperatures recorded before the widespread use of fossil fuels. The best guess is around 1.5C. He's confident that even if the last few days are cooler, the margin of error is enough to make July the hottest yet seen.

If you are an interested ASIF member or visitor , there was no new news today . It's been here all week , month and year .

[be cause]

up , up , and away ! the day old Arctic temp record shattered again yesterday . New record (CR) : 5.81'C , anomaly 1.89'C .
   Interesting that the record breaking has shifted from the Southern to the Northern hemisphere during the last month .

Interesting that the record breaking has shifted from the Southern to the Northern hemisphere during the last month.

I agree, but I'm not sure if it's specifically NH vs. SH. Right now, the tropics are the biggest outlier, followed by NH as a whole, and of course the high Arctic. I wonder if this is really a NH/SH distinction, and not just "Antarctica vs. everything else"?

[be cause]

I should have backed a few horses this summer .
 
   Arctic record heat continues . rising to 5.91'C yesterday . 

World record heatwave enjoyed it's 26th concsecutive day .

A new N. hemisphere record of 22.61 , 0.43' higher than the record before the current run of 13 days .

   If aliens are monitoring our planet from afar , the temperatures atm must suggest something catastrophic has/is happening .

maybe it's intentional ( what do you call terraforming when you're not from Terra) ...

[kassy]

But that is just thinking about it through the Hollywood lens.

If they are monitoring from afar, lets say light years away with a really good telescopethey might notice (but only years in the future). If they have a more local probe it would also pick up the TV signal which would be more then enough to conclude this planets population is insane.

We did all this ourselves while knowing about it for decades.

We still have the EN year to go after this. I really wonder where that will take us.

So apparently Morocco has just seen a new national high temperature record of 50.4 Celsius (122 Fahrenheit), the first time it’s reliably recorded a temperature above 50 Celsius. Can’t find much news or further info on this, though,

[kassy]

https://www.nu.nl/klimaat/6276277/weerrecord-in-marokko-voor-eerste-keer-in-geschiedenis-meer-dan-50-graden.html

Dutch version.

Only the second time Africa hit over 50. Ourgla, Algeria hit 50,4 C in 2014.
Also a lot of dust storms currently in northern Africa.

ETA:

The previous highest temperature, 49.9C in the Western Sahara city of Smara, was recorded on July 13, according to the weather service.

"This heat wave is due to the influx of dry and hot air from the south, causing a significant rise in temperatures, surpassing the monthly average by five to 13 degrees," the meterological authority said in a statement.

Morocco Breaks Heat Record
https://phys.org/news/2023-08-morocco.html

Temperatures in Morocco have for the first time on record topped 50 degrees Celsius (120 Fahrenheit), the North African country's meteorological service said Sunday amid a scorching heat wave.

The meteorological station in the southern coastal city of Agadir recorded on Friday the new national record of 50.4C, said the General Directorate of Meteorology.

The previous highest temperature, 49.9C in the Western Sahara city of Smara, was recorded on July 13, according to the weather service.

https://en.hespress.com/69107-morocco-sweats-through-intense-heat-wave-breaking-records.html

The intense heat wave, known as the “chergui” effect, resulted from hot, dry air masses originating in the Sahara Desert, sweeping into Morocco.

Chergui winds carrying the desert air intensified over the High and Small Atlas mountain ranges, exacerbating the heatwave and triggering thunderstorms and dust storms in areas including High Atlas, Marrakech, and Agadir.

A historic moment occurred at the Agadir-Inezgane weather station, registering a new national temperature record of 50.4 degrees Celsius at 1:33 pm, surpassing the previous record of 49.9 degrees.

Agadir Ait Melloul also set a new record at 50.2 degrees Celsius, breaking the prior record of 49.5 degrees. Tan-Tan reached 48.2 degrees, overtaking the earlier record of 47.6 degrees. Tiznit hit a new monthly peak of 48.3 degrees Celsius, outdoing the previous record of 47 degrees.

https://www.nasa.gov/press-release/nasa-clocks-july-2023-as-hottest-month-on-record-ever-since-1880

Overall, July 2023 was 0.43 degrees Fahrenheit (F) (0.24 degrees Celsius (C)) warmer than any other July in NASA’s record, and it was 2.1 F (1.18 C) warmer than the average July between 1951 and 1980.

“This July was not just warmer than any previous July – it was the warmest month in our record, which goes back to 1880,” said GISS Director Gavin Schmidt.

Record highest 0 degrees Celsius line in Switzerland:

Zero-degree line at record height above Switzerland as heat and fire hit Europe
Weather balloon climbs to 5,300 metres before temperature falls to 0C amid late summer heatwave
Jon Henley Europe correspondent
@jonhenley
Mon 21 Aug 2023 12.38 BST
A Swiss weather balloon had to climb to an unprecedented 5,300 metres (17,400ft) before the temperature fell to 0C (32F), meteorologists have said, as a late summer heatwave and wildfires continue to pummel swaths of continental Europe.

A man was found dead in a blaze raging north of Athens on Monday as the Greek government warned of an extreme risk of fire across the country, while more than half of mainland France was placed under an amber extreme heat alert and local records tumbled in the south-east.


MétéoSuisse said the zero-degree line – the altitude at which the temperature falls below freezing, considered a key meteorological marker particularly in mountainous regions – was measured at 5,298 metres overnight.

The figure, which was registered by a weather balloon flown from Payerne in western Switzerland, constituted “a record since monitoring began in 1954”, the service said, and surpassed the previous high of 5,184 metres that was “only set in July last year”.


The 0C line “affects vegetation, the snow line and the water cycle, so has a considerable impact on the habitats of humans, animals and plants alike”, MétéoSuisse said. It averaged 2,570 metres above sea level from 1991 and 2020, fluctuating between 1,000 and 2,000 metres in winter, and 3,000 and 4,000 metres in summer.

In recent decades “anthropogenic climate change has caused the altitude of the zero-degree line to rise significantly in every season”, the service said, noting that successive records for the indicator had all been set in the past 10 years.

Experts have said an exceptional area of high pressure across continental Europe centred over the Alps has created a heat dome that is forecast to push temperatures to record or near-record levels in several regions until at least Wednesday.

In Greece, a shepherd who tried to save his animals was found dead as a fire raged near Boeotia, about 60 miles (100km) north of Athens. People on a beach and in two communities near the blaze were ordered to evacuate, AFP reported.


Another wildfire broke out on the island of Evia on Monday and at least four more were raging in north-eastern Greece in the regions of Rodopi and Kavala, Aspropyrgos west of Athens, and north-east Greece near the port city of Alexandroupolis, where 13 communities were evacuated over the weekend.

The EU said it was deploying two Cyprus-based firefighting aircraft and a Romanian firefighting team via the bloc’s civil protection mechanism amid what it called “by far Greece’s worst summer” for wildfires since 2008.

Civil protection authorities warned of an “exceptional” fire risk in the region around Athens and other parts of southern Greece. “We are facing extreme phenomena,” a fire service spokesperson said, urging people to follow authorities’ instructions.

In Spain, the state weather agency, Aemet, has placed five provinces in the southern region of Andalucía on amber heat alert, warning that temperatures are forecast to rise to more than 40C around Seville, Córdoba and in the Guadalquivir valley.


In the Canary Islands, 600 firefighters were making progress, however, battling an out-of-control blaze on Tenerife that was started deliberately and has forced more than 12,000 people to flee their homes and burned through more than 12,800 hectares (31,600 acres) of land, about 6.5% of Tenerife’s surface area.

The prime minister, Pedro Sánchez, said during a visit to the island that he hoped better conditions would “help us declare the fire as stabilised in the coming hours, coming days. The next few hours are going to be very important.” Spain has suffered 340 fires so far this year, which have ravaged almost 76,000 hectares, EU figures show.

In France, record temperatures of more than 42.5C were recorded along the Rhône valley and at several other south-eastern weather stations, with the mercury set to rise further on Tuesday and Wednesday.

Fifty of the country’s 96 mainland departments were on amber heat alerts, with some expected to be placed on a maximum red warning over the next few days.


After weeks of dry weather, local authorities in Gard département restricted access to forests due to the high risks of fires, while firefighters were battling a blaze near the village of Chanousse in the south-east that had so far consumed about 120 hectares (296 acres) of forest.

The highest temperature ever recorded in France was 46C, registered in June 2018 in the village of Vérargues in southern France.

Milan Records Hottest Day Since 1763
https://www.reuters.com/world/europe/milan-records-hottest-day-since-1763-2023-08-25/

ROME, Aug 25 (Reuters) - Italy's northern city of Milan registered a new record high average daily temperature of 33 Celsius (91.4 Fahrenheit) on Wednesday as a heatwave which began around mid-August reached its peak, the regional environmental protection agency (ARPA) said on Friday.

It was the hottest day since the Milano Brera weather station started recording temperatures in 1763. Milan's previous record of 32.8 C was set on Aug. 11, 2003.

The Italian capital Rome registered a record peak of 41.8 Celsius (°C) in July, as much of southern Europe broiled this summer, fuelling wildfires, prompting governments to issue health warnings, and disrupting holidays for many tourists.

ARPA said in a statement that Aug. 23 and 24 have been the hottest days of the summer across the whole of the Lombardy region which surrounds Milan, with several towns registering peak temperatures above 40 C.

It added that "intense and abnormal" temperatures also hit the Italian Alps.

Japan's summer this year has its recorded highest average temperature since records began 125 years ago, the country's weather agency said on Friday.

“In the summer of 2023, the average summer temperature in Japan was considerably higher in northern, eastern and western Japan. Average temperatures in Japan are the highest for summer since 1898,” the Japan Meteorological Agency said.

Based on measurements at 15 locations around the country from June through August, the average temperature deviation was +1.76C, the agency said. That exceeded the previous record of +1.08C in 2010.

Between 16 July and 23 August, the maximum temperature records were broken at 106 of 915 monitoring locations across Japan, it said.

High temperatures have continued even into the beginning of autumn, with “extremely hot days” being recorded in the city of Sapporo.

Earlier in August, Japan recorded the hottest day of the year as temperatures hit 40C in the Fukushima Prefecture. The country recorded its hottest average July temperatures in more than 100 years.

India reports its hottest and driest August on record:

https://www.euractiv.com/section/climate-environment/news/india-sees-hottest-driest-august-since-records-began/

India has reported its hottest and driest August since national records began more than a century ago, the latest in a string of records broken worldwide as climate change intensifies.

August falls in the middle of India’s annual monsoon, a season that usually brings up to 80% of the country’s yearly rainfall.

Heavy downpours brought deadly floods to parts of India’s north during the month, but on the whole, rains were much more subdued, resulting in record heat.

“Average mean and maximum temperatures in August 2023 were the record highest since 1901,” the India Meteorological Department (IMD) said.

“The large rainfall deficiency and weak monsoon condition is the main reason.”

IMD data showed August average rainfall of 161.7 millimetres this year, 30.1mm lower than the previous August record in 2005.

The forecast for September is wetter, however:

https://m.timesofindia.com/india/imd-this-august-driest-hottest-since-1901-in-india/amp_articleshow/103262205.cms

A bit of relief is, however, expected in September as the monsoon rainfall activity in the month is going to be ‘normal’ in the country as a whole. But the overall seasonal (June-Sept) rainfall is likely to be ‘below normal’ due to the huge deficit (36%) in August. “Overall, the monsoon season (June-Sept) in the country as a whole is not going to be deficient,” said IMD chief M Mohapatra.
IMD chief M Mohapatra on Thursday indicated that the total deficit at the end of the four-month season may not exceed 10%. It means 2023 will not end as a drought year like 2014 and 2015 even as the cumulative monsoon rainfall (June 1-August 31) has already reached a deficit of 10% as on Thursday.

UK Experiencing Longest September Heat Wave
https://phys.org/news/2023-09-uk-experiencing-longest-september.html

Britain is experiencing a record-breaking period of hot September weather with Friday expected to be the fifth consecutive day of temperatures climbing above 30°C (86°F).

This week has already broken the record for the number of consecutive September days with the temperature topping 30°C, according to Britain's Meteorological Office.

The previous record was three consecutive days, seen four times before, most recently in 2016.

... Temperatures could reach 32°C in southeastern England on Saturday before easing off on Sunday and Monday, the Met Office added.

[Renerpho]

Global air temperature anomaly yesterday was 1.08°C, compared to the 1979-2000 baseline. I believe that's the highest it ever was. The previous record was 1.02°C from 6 July 2023.

Add 0.31°C to convert that to the more commonly used 1951-1980 baseline, or 0.34°C if you prefer the 1901-2000 baseline instead.
