MiRCH Roundup November 2025 – January 2026: Militaries Scramble Across South and South-East Asia to Respond to Back-to-Back Disasters

By Noah Fritzhand

From November 2025 through January 2026, the Military Responses to Climate Hazards (MiRCH) tracker documented 41 military deployments in 15 countries to address climate hazards. As 2025 wound down, countries in South and Southeast Asia were slammed by typhoons and devastating flooding. Notably, multiple militaries also deployed to assist Sri Lanka in the wake of Cyclone Ditwah, which Sri Lankan leaders have called the “largest and most challenging natural disaster” in their history.

MiRCH Updates, June – October 2025:  Militaries Intervene Worldwide During Wildfire and Tropical Cyclone Season

By Tom Ellison and Noah Fritzhand

From June through October 2025, the Military Responses to Climate Hazards (MiRCH) tracker documented 80 military deployments in 25 countries to address climate hazards. Most notably, these five months saw military deployments in response to the devastating impacts of tropical cyclones and torrential rain in transboundary regions across the Indo-Pacific and Caribbean, wildfires across North America and Europe, and severe storms and flooding in the United States. These incidents underscore the implications of preparedness and response cuts in the United States; the challenges of compounding, transnational disasters; and the intersection of disaster relief and conflict.

MiRCH Update: Military Responses to Climate Disasters Across the United States

By Tom Ellison

Introduction

The Center for Climate and Security’s (CCS) Military Responses to Climate Hazards (MiRCH) tracker now includes 501 deployments in 97 countries between June 2022 and February 2025–averaging more than one every two days. In light of the military response to January’s devastating wildfires in California and ongoing policy debates about US domestic disaster relief, now is a good time to analyze what MiRCH tells us about military responses to disasters such as wildfires, hurricanes, and flooding within the United States.

December 2024 Update: Military Responses to Climate Hazards (MiRCH) Tracker

By Ethan Wong

In December 2024, the Military Responses to Climate Hazards (MiRCH) identified 4 military deployments regarding climate-related disasters. 

On December 14, Tropical Cyclone Chido struck the French overseas department of Mayotte off the coast of southeast Africa as a category 4 storm before continuing on toward Mozambique and Malawi. The cyclone was the strongest storm to hit Mayotte in over 90 years and brought near-total destruction to the island. In response to the overwhelming damage, the French military deployed hundreds of personnel to the territory to distribute emergency supplies and support rescue and recovery operations. French military aircraft and naval vessels also delivered hundreds of tons of aid and equipment to Mayotte, including food, water, and other critical provisions. Meanwhile, in Malawi, search and rescue teams that included members of the Malawi Defence Force were placed on standby in preparation for Cyclone Chido.

The devastating impacts of Cyclone Chido on Mayotte highlight the growing climate insecurities on the overseas department and other island territories as global temperatures increase. For example, in September 2023, sustained drought amplified by climate change triggered an unprecedented water crisis on Mayotte, prompting the deployment of French troops to distribute water to local communities. The situation on Mayotte reflects the challenges of many other island nations, which are particularly vulnerable to the impacts of climate change and will likely require greater assistance in response to more frequent and severe climate-related disasters in the future.
