Grenada, like many Caribbean small island developing states (SIDS), faces intensifying climate impacts with limited resources yet enduring resilience. Rising temperatures—projected to reach 2.9°C by 2100 under high-emission scenarios—are exacerbating vulnerabilities and threatening health infrastructure and disease patterns. Sea level rise poses a major risk to coastal zones and tourism (73% of structures are coastline-based), with a 0.5-meter rise expected to erase up to 60% of beaches.

The nation has endured major climate shocks: Hurricanes Ivan (2004), Emily (2005), and most recently, Hurricane Beryl – 2024 causing over $950 million in damages (Ivan & Emily) and impairing 69% of health facilities. Grenada also grapples with alternating droughts, heat waves and floods, affecting sanitation, agriculture, solid waste and water systems. Health repercussions include:

Direct impacts: trauma, heat stress, post-disaster mental health strain.

Indirect effects:

• Vector-borne diseases (e.g. dengue, Zika, chikungunya);
• Waterborne illnesses (e.g. leptospirosis, gastroenteritis);
• Respiratory ailments (e.g. from Saharan dust);
• Food insecurity;
• Stress-related cardiovascular disease.
