Why is it hot in Europe this week?
Well, it has to do with the “omega block” in the jet stream. Omega blocks get their name because they resemble the Greek uppercase letter omega, Ω.
You can see that in the synoptic setup. The map below on the left shows the 500 mb geopotential height anomaly at 18z. The contour lines resemble the Ω shape due to an enormous high-pressure ridge in the mid-troposphere that is sandwiched between two low-pressure systems to its east and west.
Hot Saharan air has been advected—that is, horizontally transported—northward into western Europe due to anticyclonic (clockwise) airflow, and as that air mass moves north, it is compressed adiabatically beneath the ridge where air is sinking.
This process is natural and has nothing whatsoever to do with climate change or greenhouse gas emissions. In fact, there are quite a few studies suggesting that reduced latitudinal baroclinicity (north-to-south temperature gradient) caused by Arctic amplification could reduce the frequency of mid- and high-latitude blocking events (e.g., Hassanzadeh et al., 2014; Woollings et al., 2018).

There is, however, debate about this.
Europe has seen an unusual amount of these extreme heat events since 2019, but most other areas of the globe have not. The notable exception was the June–July 2021 Pacific Northwest heatwave in North America, but even that wasn’t as rare as previously thought.

The most likely explanation for this boils down to a combination of two things:
1️⃣ Undiagnosed changes in atmospheric circulation patterns.
2️⃣ Increased absorbed solar radiation at the surface due to reduced stratiform low- and mid-level cloud cover (increased sunniness), some of which is likely due to reduced atmospheric aerosol concentrations from the EU’s strict pollution regulations.
The overall increase in the “global mean temperature” (which mostly affects overnight lows) has very little to do with this event. Even in a “pre-industrialized” climate, a record-breaking heatwave would still be happening. Heck, the “global mean temperature” fell today despite the heat cranking up in Europe.
This is mostly weather systems moving around. When you have a chaotic system with two turbulent fluids interacting with each other (the atmosphere and ocean), wild things can happen.
Get your weather information from real meteorologists, not sensationalistic clickbait news outlets like BBC News or the Daily Mail.
Zohran Mamdani says America should follow the example of Islam and “Prophet Muhammad” on migration.
Fun fact: After conquering Mecca, Muhammad deported all the Christians and Jews and banned them from entering the city ever again.
To this day, non-Muslims can’t set foot in Mecca for being considered dirty and impure.
Does Mamdani want to turn New York into an all-Islamic city like his prophet did in Mecca?
The man who won the Democratic primary in New York tonight stood in a mosque two days ago and recited the Quran, and the Muslims there prayed that Allah would kill the infidels with his sword. Very dark times are coming.
🚨AMERICA!! ARE YOU PAYING ATTENTION?? What happened in NY last night is a clear signal of the Democratic Socialist Agenda for AMERICA.
DSA Marxists and their allies just swept key primaries: 3 for 3
They want open borders, endless welfare, Sharia creep, and the erasure of American exceptionalism. They cheer Hamas, demonize Israel, and treat our cities like conquered territory. New York, the city that suffered 9/11, is now their beachhead.
America First or America lost. Wake up before it's too late. 🇺🇸
Today, I exposed the true face of @_VanessaFrazier, the UN Secretary-General’s Special Representative for ‘Children and Armed Conflict’.
Before presenting yet another report against Israel, the facts came to light:
• She engaged with antisemitic social media accounts.
• She amplified defamatory accusations against Israel.
• She shared false allegations that proved to be unfounded.
Ms. Frazier is not the exception.
She reflects a deeper problem within parts of the UN, where bias against Israel too often outweighs the commitment to truth and impartiality.
The lesson of New York City elections is that if you continue to allow millions of retarded foreign communists into your country, the communists are going to take over your entire country, block by block and city by city.
They will seize your homes and your retirement accounts and the inheritance you set aside for your children and grandchildren, and there will be nothing you can do to stop them.
You either stop the immigration and send them all back, or you lose your country and everything you own.
The world is outraged about why Israel is in Lebanon.
This is Hezbollah's massive underground terror tunnel, full of weapons, just a few miles from Israel's border.
And there is your answer to why Israel is fighting in Lebanon.
This is what you are quoting when you use the UN to justify an argument. This UN Special Rapporteurs face when this brave woman demands she look at her tells you all you need to know.
.@ScottJenningsKY: “What is happening right now in New York City, the Democratic Socialist takeover of the Democrat Party should frighten not just Jewish Americans but all Americans everywhere because this is the direction the Democrats are headed nationally.”
Watch closely new video showing the U.N. reaction: as courageous former hostage Ilana Gritzewsky confronts October 7th denier Reem al-Salem—by recounting the horrific abuse she suffered from Hamas—the U.N. rapporteur on violence against women sits there stone-faced. No empathy.
A majority Muslim city council in Michigan voted to permanently ban the LGBTQ Pride Flag on public property.
White liberal women who welcomed refugees from Islamic countries are now wondering what happened.
Consequences of suicidal empathy coming to a leftist town near you.
If Andy Burnham claims he was unaware of the details of the Muslim grooming gangs then please send him this clip where he was questioned by the families of the victims.
