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.”
