Glaciers: A Photo Essay

September 19, 2017

“The alarming rate of glacial shrinkage worldwide threatens our current way of life, from biodiversity to tourism, hydropower to clean water supply.” (climatenewsnetwork.net)

During and in between NWNL’s dozens of expeditions to its six case-study watersheds, we have explored the value and current condition of glaciers on three continents, since they are a critical source of freshwater.  NWNL visited the Columbia Icefields of Alberta, Canada in 2007; Argentine glaciers in 2003 and 2005; and Rebman Glacier on the summit of Tanzania’s Mt Kilimanjaro in 2003.   We have witnessed the effect of climate change on glaciers. The melting of glaciers will affect  all forms of water resources for human and wildlife communities.  Just as upstream nutrients and pollutants travel downstream, “the loss of mountain ice creates problems for the people who live downstream.” Glacial loss must be thought of as just as important in the climate-change discussion as flooding and drought have become.

In honor of those devastated by the recent flooding all over the world, including Texas and Florida in the United States, the Caribbean, Africa and across Southeast Asia, NWNL takes a look at photos from our archives of flooding in our case study watersheds.
