There has been a sharp increase in discussion of climate change weather extremes in the context of the flood calamity in Western Europe, wildfires in the North West US, and the #ArabianMonsoonBurst

This thread looks at the big picture right now. What's next?

@meteoblue

The image above from @meteoblue shows most of the Northern Hemisphere & rainfall at the moment. The intense blobs of colour indicate high rainfall from thunderstorms.

What is immediately apparent looking at this is that there is an immediate issue now in the West Pacific.

What will soon be Typhoon In-Ha is forecast to make landfall in Taiwan and then stall bringing massive rainfall to the Philippines, China and Taiwan.

There is second tropical storm to the left of what will soon be In-ha which is simultaneously bringing extreme weather to HK.

The German and European low country flooding of last week is astonishing and terrifying. This thread compiles youtube videos of the coverage. The death toll is still expected to rise significantly.

@Channel4News

The previous video was @Channel4News 16th July report. Here is their 17th July report.

Here is the BBC report from Friday 16th.

Today is possibly the apex of this #ArabianMonsoonBurst which began several days ago now. It's hard to imagine it getting bigger than this.

Today's #NorthAfrican #HornOfAfrica and #MiddleEast rainfall forecasts follow.

The animation above is for 12 hours hence the arriving and departing light effect. As always the engine behind this is the Indian Monsoon which you can see here this morning gathering strength.

A close up from the end of today shows how the big storms over #SaudiArabia are generating new atmospheric rivers of moisture, or plumes, over the Sahara, you can see these top right.

[Note: Atmospheric rivers are often invisible, this one becomes visible as night falls.]

This is a long statement, probably a bit too long, but interesting and important. My reading is that Ethiopia has not yet decided to abandon the unilateral ceasefire, but that frustration is going, both with the TPLF and their ongoing offensive....

... and with ongoing one-sided diplomatic/media understanding of the Tigray conflict.

@nytimes

The @nytimes story from @declanwalsh (see below) has become a lightning rod for public and government concerns that Ethiopia is not being listened to or being given due respect internationally.
