5 ways the Iran conflict is upending Europe’s energy plans The EU already had energy problems. The chaos in the Gulf just made them a whole lot worse.

Enerji Krizi: ABD-İsrail-İran çatışması Hürmüz Boğazı'ndaki sevkiyatları durdurdu. Gaz fiyatları ikiye katlandı (56€/MWh) ve petrol %10 arttı. Gaz rezervleri son 4 yılın en düşüğüne (%30) indi. Dev tanker şirketleri geçişleri askıya aldı. Katar LNG üretimini durdurdu. www.politico.eu/article/5-wa...

5 ways the Iran conflict is upending Europe’s energy plans The EU already had energy problems. The chaos in the Gulf just made them a whole lot worse.

Energy Crisis: The US-Israel-Iran conflict has halted Strait of Hormuz shipping. Europe faces major risks: Gas prices doubled to €56/MWh and oil is up 10%. Gas reserves hit a 4-year low of 30%. Major tankers suspended transit. Qatar halted its massive LNG production. www.politico.eu/article/5-wa...

1869’da Dmitri Mendeleev ilk Periyodik Tabloyu yayımladığında yalnızca ~60 element biliniyordu.

En önemli yeniliği ise bilinmeyen elementler için boşluk bırakmasıydı.

Bu boşluklar daha sonra Gallium, Germanium ve Scandium ile dolduruldu.

In a heatwave, a cool library or shopping centre is a lifeline. Do we need more climate shelters? On a hot or smoky day, a shopping centre or library can offer refuge. We need to design climate havens with the warming future in mind.

Aşırı sıcaklar ve orman yangını dumanı evleri güvensiz kılarken, şehirler ücretsiz klima, temiz hava ve Wi-Fi sunan İklim Sığınaklarına yöneliyor. Barselona'dan Avustralya'ya uzanan bu kapsayıcı merkezler, en savunmasız sakinleri korumayı hedefliyor. #İklimEylemi theconversation.com/in-a-heatwav...

In a heatwave, a cool library or shopping centre is a lifeline. Do we need more climate shelters? On a hot or smoky day, a shopping centre or library can offer refuge. We need to design climate havens with the warming future in mind.

As extreme heat and bushfire smoke make homes unsafe, cities are turning to Climate Shelters—public spaces offering free AC, clean air, and Wi-Fi. From Barcelona to Australia, these welcoming community hubs aim to protect the most vulnerable. #UrbanResilience theconversation.com/in-a-heatwav...

Warming is no longer just about degrees — it’s about acceleration.
If feedbacks and tipping points activate, the system could heat itself.
Uncertainty isn’t comfort. It’s a warning. 🌍 www.cell.com/action/showP...

Isınma artık sadece artış değil, hızlanma sorunu.
Geri beslemeler ve devrilme noktaları devreye girerse sistem kendi kendini ısıtabilir.
Belirsizlik beklemek için değil, önlem almak için bir neden. 🌍

Why Rain Doesn't Instantly Fill Dams:

It is raining but the reservoirs are not filling In recent weeks, we have been hearing the same sentence almost every day: “Rainfall has increased in Türkiye, but reservoirs are not filling...

Lately, many people have been asking why the reservoirs are not filling quickly enough, even though we are receiving ample rain. Here is my take on the issue:

Yağmur Yağıyor Ama Barajlar Dolmuyor mu? Son haftalarda neredeyse her gün aynı cümleyi duyuyoruz: “Türkiye’de yağışlar arttı ama barajlar dolmuyor.” Bu cümle çoğu zaman bir adım dah...

Son günlerde birçok kişinin konuştuğu soruya cevap aradım: Bu kadar yağmur yağıyor ama barajlar neden dolmuyor?

As Milano–Cortina 2026 begins, the real story isn’t medals—it’s the climate limits behind the slopes. Artificial snow, rising costs, and shrinking winters show the Winter Olympics must adapt or disappear. #ClimateChange #MilanoCortina2026

Is petroleum a "renewable" resource hidden by monopolies, or a finite gift of millions of years of photosynthesis? ☀️🛢️
We must face the reality: we are burning a million-year accumulation in just centuries.

The Hubris of Taming the Skies: The Chasm Between Cloud Seeding and Reality Human history is a saga of oscillation between the desire to dominate nature and the devastation wrought by that very ambition. Nowadays, wh...

Technology cannot fix the climate systems we’ve broken with emissions. We must stop looking for "technological patches" for extreme weather and start facing the bitter truths of water justice.
Nature is not a machine to be tamed.

Sel riski sadece yağışla ilgili değil. Bu çalışma, farklı sosyoekonomik yolların (SSP’ler) sağlık, tarım, ulaşım ve su sistemlerinde sel kırılganlığını nasıl artırıp azaltabileceğini gösteriyor. Uyum bir kalkınma tercihi.

Flood risk is not only about rainfall.
This study shows how different socio-economic futures (SSPs) can either reduce or amplify flood vulnerability across health, agriculture, transport & water systems. Adaptation is a development choice.

Gelişmekte olan ülkelerdeki metan salımlarının büyük bölümü küresel tüketimden kaynaklanıyor.
Toplam alanın %10’u, salımların yaklaşık %70’ini oluşturuyor.
Metan sadece üretim değil, tüketim sorunu.

Most methane emissions in emerging economies are driven by global demand. Just 10% of land accounts for ~70% of the methane footprint—and much of it is linked to EU & US consumption.
