Yes, of course, pressure from that front must be enormous. Now we see what kind of politicians stand up to such pressure and do the right thing, and which ones cave to the pressure.
Meanwhile, more info on the atmospheric conditions that helped spawn the SL disaster (yes, along with bad land management, and also bad settlement patterns, bad sewage management...):

This summer, the waves moving off Africa and through the Atlantic have been unusually strong, leading to a very active early season across the Main Development Region of the Atlantic.
Tropical Storm Bret, which developed east of the Lesser Antilles in June, was among the earliest Cape Verde tropical storms on record. Bret was followed in July by Don, another unusually early Cape Verde tropical storm.
The heaviest downpours in many parts of the globe have become heavier in recent decades, a trend attributed to human-produced climate change and expected to continue.
A study led by Christopher Taylor (UK Centre for Ecology and Hydrology), published this spring in the journal Nature, finds that the Sahel’s most intense mesoscale convective systems (organized clusters of thunderstorms) have tripled in frequency since 1982.
They argue that Saharan warming is helping to intensify convection within the MCSs through increased wind shear and changes to the Saharan air layer.
“The meridional gradient is projected to strengthen throughout the twenty-first century, suggesting that the Sahel will experience particularly marked increases in extreme rain,” the study concludes.
