Global warming pictures before and after

Some of the glaciers in the park are now one-third of their estimated maximum

Photos released this year by Glacier National Park, Montana offer evidence that global warming is not only ongoing – but is having real, and drastic effects on the world around us.

The images compare glaciers seen as they are today with archive shots dating from the 19th century onwards, with the images taken at roughly the same time of year.

The glaciers are predicted to disappear entirely by 2030.

Daniel Fagre, a Research Ecologist at USGS, working with the park says, ‘Glacier National Park’s namesake glaciers have receded rapidly since the Park’s establishment in 1910, primarily due to long-term changes in regional and global climate.

‘In the last century, the five warmest years have occurred in the last 8 years – in this order: 2005, 1998, 2002, 2003, 2004. This warming is ongoing and the loss of the Park’s glaciers continues, with the park’s glaciers predicted to disappear by 2030.’

Last year was the warmest on record, according to Nasa

The Repeat Photography Project ‘matches’ new photos of glaciers in Glacier National Park with archive photographs, to show the shocking impact of warming on the park’s namesake glaciers.

Fagre says, ‘With evidence of worldwide glacial recession and modeled predictions that all of the park’s glaciers will melt by the year 2030, USGS scientists have begun the task of documenting glacial decline through photography.

‘Since 1997 over sixty photographs have been repeated of seventeen different glaciers. Thirteen of those glaciers have shown marked recession and some of the more intensely studied glaciers have proved to be just one-third of their estimated maximum size. In fact, only 26 named glaciers presently exist of the 150 glaciers present in 1850.
