The main purpose of this ongoing blog will be to track planetary extreme, or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😜
Here is a new feature for this blog, which I will add daily. This is the latest inciteful Green News Report from my friends Desi Doyen and Brad Friedman at Progressive Voices. Hit ‘continue reading,’ listen, then hit return to see my daily topics:
Main Topic: European Heatwave Ember Ramps Up to a Catastrophic CAT5
Dear Diary. Unfortunately, due to climate change we have another top tier CAT5 heatwave on our hands, which is becoming more common with time. Heatwave Ember will get pegged on this list because it will probably rack up at least ten thousand fatalities before its heat dome collapses.
As you know, I have been naming and categorizing heatwaves on a scale of 1 to 5 with guidelines here:
My last report on Ember was on Sunday:
As far as Ember’s heat done goes, here was its state during Europe’s afternoon today:
The dome has come down a bit from what it was on Monday but remains very strong:
Amber’s heat dome will move eastward and restrengthen later this week, so Germany and other central European nations will continue to roast:
Here is one of the latest summaries on Heatwave Ember from the BBC, this time focusing on France:
Europe heatwave: Power outages hit France as it records hottest day since measurements began
Power outages hit France as it records hottest day since measurements began

France has recorded its hottest day since records began in 1947, its national weather agency says, breaking a record set on Tuesday as an early summer heatwave grips western Europe.
The national temperature indicator – an average of day and night temperatures across dozens of locations – hit 30C, up from 29.8C a day earlier.
More than half the country remains under a red heat alert with tens of thousands of homes in the west without power. The temperature in Paris and many other areas broke 40C on Wednesday.
It comes as a searing European heatwave continues to cause deaths and disruption, particularly in France, Spain and Italy.
Climate change is driving up temperatures around the world – but particularly in Europe. It is the fastest warming continent, heating up twice as fast as the global average, according to the Copernicus climate service.
This is causing increased summer heatwaves, greater pressure on Europe’s water supply, and more intense wildfires.
The heatwave spread to other parts of western Europe on Wednesday, with an orange alert for dangerous weather in place for parts of the Netherlands.
A rare red heat alert is in place for parts of the UK, with June records breaking on Wednesday as the English county of Hampshire recorded 36.1C. Temperatures could hit 38C on Thursday, forecasters say.
Meanwhile, Météo-France recorded provisional maximum temperatures across the country that “remained relatively stable compared to the previous day”.
Highs ranged from 39C to 42C across much of western France, with 43C recorded in the Poitou-Charentes-Val de Loire region, slightly lower than the 44.3C seen in Pissos on Tuesday.
Overnight, minimum temperatures had exceeded 28C in the Vendée region and over 25C in Paris.
Temperatures are expected to peak in the Netherlands and Belgium on Friday, while the temperature in Germany is expected to rise to 40C over the weekend.
The heatwave will also extend to eastern Europe over the next few days, with severe heat warnings issued for countries including Poland, Croatia and Hungary for later in the week.
So far, France, Spain and Italy have been hardest hit by the heatwave.
At least forty people have drowned in heatwave-related incidents in France since last Thursday, according to the prime minister.
On Wednesday, red alerts in France were extended to include four more regions, Météo France said, bringing the total number to 58.Thirty-one more regions are under an orange alert.
Some relief from the heat in France is expected from Friday, with temperatures forecast to gradually drop over the weekend. This change will come with thunderstorms, bringing a risk of flash flooding and large hail.
Speaking to French radio, labour minister Jean-Pierre Farandou said “we’re in the process of finding out we’ve become a hot country” and warned society may need to adapt.
Authorities warn that the risk of forest fires is higher during such a prolonged and intense heatwave.
In the Maine-et-Loire region, more than 150 firefighters were deployed to fight a major fire on Tuesday in the Breignon forest in Saint-Macaire-du-Bois. It was brought under control overnight, authorities said, with no-one reported injured.

Sights in the French capital Paris have also been impacted by the hot weather.
The world’s most visited museum, the Louvre, said it would close its doors earlier this week.
The Louvre said its historic building “remains fragile, external and is not sufficiently adapted to climate change”, adding that the “build-up of heat is at its highest at the end of the day, and intensified by the volume of visitors”.
The Eiffel Tower also closed earlier than usual on Tuesday and was to do so again on Wednesday.
Among those who died in heatwave-related drownings was a six-year-old child who had gone to an unsupervised beach with his parents in Bègles, Gironde on Tuesday evening.
A 17-year-old girl also drowned while swimming in a prohibited area of the Marne river in Champs-sur-Marne, on the outskirts of Paris.
While Spain has experienced baking heat over the last few days, temperatures were expected to start falling on the Iberian peninsula on Wednesday.
But red heat alerts remain in place for parts of northern Spain, with a maximum temperature of 42C possible in parts of the Basque country, forecaster Aemet said.
Spain’s state meteorological agency said the country recorded its highest daily average temperatures in June since at least 1950, with Tuesday’s average of 28.17C breaking the previous 2025 record of 28.01C.
In Italy, meanwhile, 16 provincial capitals are now under red heat alerts, with Latina added to the list on Wednesday, while Bari will be added on Thursday, Italian news agency Ansa said.
The Dutch weather service, the KNMI, has issued a Code Orange weather alert, which refers to a “high chance of dangerous weather” in southern and central areas of the Netherlands from Wednesday until at least Friday.
KNMI said maximum temperatures of 37C were expected, while Friday could see the mercury hit 39C.
In Belgium, most of the country is under an orange alert with highs of 37C expected over the next few days.
After meeting on Tuesday, Belgium’s Risk Management Group said it was activating the “alert phase of the national ozone and heat plan” for only the second time. The first occasion was in August 2020, although no specific national measures have been announced, other than to raise awareness and call for extra care for the elderly and children.
