This uptick is in spite of the fact that far fewer people are attempting the crossing—327,800 so far this year, compared with 1,015,078 last year. The higher fatality rate may be due to a range of causes, from smugglers taking more dangerous routes to using flimsier vessels. Bad weather has also played a role in some deaths.

UNHCR is urging countries to make safer pathways available and consider “enhanced resettlement and humanitarian admissions, family reunification, private sponsorship, and humanitarian, student and work visas for refugees.”
