A new study has just confirmed that billions of people depend on snowfall for water supply, and snowpacks are currently shrinking in areas where climate temperatures are rising.
The New York Times posted an article about an earth scientist and his colleagues from Columbia University, who “analyzed 421 drainage basins in the Northern Hemisphere that depend on rainfall and snowmelt, and then combined the data with several different climate models.
They found that 97 basins, currently serving two billion people, depend heavily on snowmelt. The scientists calculated that the likelihood the basins would receive less snow in the coming century was 67 percent.”
Some of the most affected basins in United States are located in Northern and Central California. Thanks to this study, city water managers are able to make more efficient plans for water usage. Read more here.
