This Is Why

When an event discussing extreme heat at London Climate Week is called off due to... extreme heat, you know things are bad. In the words of UN Secretary General Antonio Guterres, “London is cooking.” Yes, it’s summer and heatwaves are hardly a rarity. But as record temperatures in June follow record temperatures in May – it's the frequency and severity of these weather events that are frightening forecasters and climate scientists. With a rare red heat warning in place across much of England and Wales, hundreds of schools have closed, travellers have been warned to avoid public transport and there are threats of power cuts. But as our summers become ever hotter, are we doing enough to adapt national infrastructure? And why are politicians so hesitant to take transformative climate action?

But the key objective of allowing global shipping to pass freely through the currently Iran controlled Strait of Hormuz is far less straightforward than it may appear. From the threat of minefields to a change of heart over military action, it could take months – if not longer – for the region to return to normal.
