Evidence of the effects of climate change continues to mount. We see it in extreme weather events, including droughts and intense hurricanes and cyclones, in biodiversity loss, and in erratic weather patterns around the globe. While many of these impacts rightfully make it into front-page news, climate change is also profoundly affecting parts of our planet that we do not understand well—the ocean and the cryosphere.

In September 2019, the International Panel on Climate Change issued a Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC). The report provides a new and sobering analysis of current conditions, as well as projections into the future. Produced by more than 100 authors from 36 countries, the SROCC painstakingly reviews the latest scientific literature, referencing some 7,000 scientific publications in all.

As disasters have changed over the years, so must the personnel who manage these crises.

In 1932, sociologist Lowell Carr first described a predictable pattern of how disasters impact society. Refined over the decades by many researchers, the “disaster cycle” includes four phases: prevention, preparedness, response, recovery and rehabilitation.

This disaster cycle helped define the way societies respond to each disaster. Today, highly trained emergency personnel using many research, management, and epidemiological skills have helped improve survival and health outcomes after disasters. “Disaster medicine” now defines a sub-specialty for highly skilled professional health specialists. However, their many activities and skill sets primarily focus on only the response phase of the initial disaster cycle.

If you have even a passing familiarity with the climate and security literature, you undoubtedly have come across the phrase “threat multiplier.” The phrase conveys the idea that climate change intersects with other factors to contribute to security problems. It’s used as short-hand to avoid the charge of environmental determinism, that climate change somehow on its own causes negative security outcomes.

The 2007 CNA Military Advisory Board (MAB) report on climate security introduced this formulation and, at the time, it served the purpose of recognizing that there is a link between climate change and security. But research on climate security has progressed and so must our framing of the risks and needed interventions.

As an inhabitant of the Himalayan region of Nepal, where 8 of the 10 highest peaks of the world are situated, I am experiencing first hand several environmental stresses and insecurities. Many of the high mountains I can see from my village, once covered in snow, are turning black. Neighboring areas are experiencing massive out-migration and demographic changes. Consequently, agriculture in the region is facing an unprecedented crisis.

Droughts, irregular rainfall and erratic floods, landslides and mudslides, forest fires, pollution of our land and water, and energy insecurity are frequently observed in Nepal. River systems born out of the Himalayas are shrinking. Erratic climate behavior is heavily affecting the flora and fauna and contributing to biodiversity loss.
