Article In Nature “Cold Empties Bolivian Rivers Of Fish” By Anna Petherick

Nature has published an excellent news article by Anna Petherick [h/t to Dan Hughes for alerting us!]

Cold empties Bolivian rivers of fish

which illustrates that even when the global average surface temperature is above average (for whatever reason) regional cold waves can occur which have major environmental consequences.

The article starts with the text

“With high Andean peaks and a humid tropical forest, Bolivia is a country of ecological extremes. But during the Southern Hemisphere’s recent winter, unusually low temperatures in part of the country’s tropical region hit freshwater species hard, killing an estimated 6 million fish and thousands of alligators, turtles and river dolphins.’

and includes the text

Water temperatures in Bolivian rivers that normally register about 15 ˚C during the day fell to as low as 4 ˚C.

Hugo Mamani, head of forecasting at Senamhi, Bolivia’s national weather centre, confirms that the air temperature in the city of Santa Cruz fell to 4 ˚C this July, a low beaten only by a record of 2.5 ˚C in 1955.

This extreme event also further illustrates why a bottom-up, resource-based perspective (in this case on ecological function on the regional scale) as presented in

A Way Forward In Climate Science Based On A Bottom-Up Resourse-Based Perspective

is needed.
