On the face of it there's a clear rationalization for the tragedy in Derna.
Two dams throughout the river that runs by the town had been too previous and too weak to deal with an unusually heavy rainstorm.
But there's one other story written within the stinking channels of mud that carved by Derna's high-rises and low-lying neighbourhoods: that susceptible locations and their individuals will undergo essentially the most by our failure to recognise and reply to the dangers of a quickly warming local weather.
Number of dead in Libya floods soars - latest updates
That's to not say climate change "caused" Derna to flood.
In the identical manner, it did not trigger wildfires this summer time.
But for each disasters, it helped set the stage - and destiny determined the play.
The human errors that led to catastrophe
There had been, after all, different very human elements that contributed to the tragedy.
The lack of flood alerts, for instance.
Then a pointless, and on reflection probably deadly, curfew on the evening the dam burst.
Perhaps most appallingly, unheeded warnings from consultants made 48 hours earlier than that the ageing dams could fail.
The ousting of Libya's dictator Colonel Gaddafi, again in 2011, was adopted by greater than a decade of political instability and civil struggle.
Such a unstable time for the nation will undoubtedly have contributed to the dearth of first rate infrastructure and flood planning.
But identical to there had been native warnings, internationally the connection between climate-related disasters and susceptible international locations has been identified for a very long time.
Chances of one other Derna rising for world's poor
This spring, the IPCC - the UN panel of worldwide local weather scientists - printed its sixth synthesis report on local weather change.
It discovered that between 2010 and 2020, human mortality from floods, droughts and storms was 15 occasions higher in extremely susceptible areas - that is these with fragile governments and infrastructure.
It went on to foretell with "very high confidence" that these dangers will improve with each increment of warming.
Derna has successfully grow to be a case examine for his or her subsequent report.
Storm Daniel, which introduced the lethal rains, had already dumped greater than 2ft of rain on components of Greece.
But because it travelled over the Mediterranean it was boosted by sea temperatures that had been two to a few levels hotter than common for early September.
That additional heat fuelled stronger winds and allowed the air to carry extra moisture, turning Daniel into what's nicknamed a "medicane" - a Mediterranean storm with the traits of a tropical cyclone.
It dumped its rain over the mountains above Derna.
In one place 414mm of rain, greater than a foot, fell in 24 hours - a brand new document, in line with Libyan climate officers.
Models predict that Mediterranean cyclones will grow to be much less frequent because the local weather warms.
However, they're anticipated to grow to be extra intense.
Whatever is constructed to interchange Derna's dams could climate fewer floods like this one in future - however they will must be constructed robust and excessive sufficient to take care of ones extra excessive than what we have simply witnessed.
A problem for a rustic left chaotic and impoverished by battle.

Fossil gas income outrage
Survivors in Derna are understandably outraged by the dearth of warnings forward of the storm and the slowness of the catastrophe response.
Yet there's one other outrage.
Libya holds Africa's largest crude oil reserves.
Oil and gasoline revenues are up; $27bn in 2022.
Yet valuable little of that huge wealth has been spent on Derna - its destruction is proof of that.
Two centuries of fossil gas burning have pushed the worldwide warming that contributes to disasters like Derna.
Yet within the case of Libya, income from the fossil gas trade seem to have accomplished nothing to assist shield its individuals from the rising dangers of local weather change.
It provides insult to the numerous accidents from the flooding.
An injustice that makes Derna's destiny an abject lesson within the unfairness of the local weather disaster.
