Indicators of a Warming World

This simple diagram of indicators of global warming in our watersheds is offered by Skeptical Science. The clear graphic approach mirrors that of the USGS Water Cycle chart above. A Creative Commons graphic, this useful educational tool raises awareness and understanding of worldwide threats of temperature rise, such as melting glaciers and sea ice, rising sea levels and shifting seasons. Go to Skeptical Science for further elaboration and for discussions of scientific rebuttals to common Climate Myths, including “climate has changed before;” “there is no consensus;” and “it hasn’t warmed since 1998.”

Spiralling global temperatures by Ed Hawkins, 2016 (0:26).

NWNL Comment: Recent prolonged droughts, raging wildfires, intense heat spells, and increasingly strong storms are subjects NWNL documents as they threaten the availablity and quality of our freshwater supplies. Higher temperatures in N. American and African watersheds – and across the globe – are in direct correlation with these destructive events. These animations published by Washington Post and Bloomberg News very clearly graph the planet’s warming from 1880 through 2015.
