A recent BBC article reported on implementing the Paris accord. Central to this agreement is limiting the amount of greenhouse gases emitted by human activity to the same levels that trees, soil and oceans can absorb naturally, beginning between 2050 and 2100. The report goes on to say that the Paris agreement, even if adhered to, is only a first major step to solving the climate change problem.
I’ve presented data in several of my earlier posts, along with a page of information from reputable scientific institutions. However, although data powerfully persuades scientists, it does not hold as much sway with the public. But photographs do. So here are some photos taken of the Grinnell glacier in Glacier National Park in northwestern Montana next to the Canadian border. In the three following photographs you will see the dramatic recession of this one glacier.
Although we know that recession would have started shortly after 1850, due to rising temperatures, note the dramatic difference between the 1940 and 2006 photographs. Collectively, these photographs are evidence of climate change acceleration. Rephotographic evidence shows that all glaciers around the world are receding, and acceleration is fastest at the poles—all inline with historical studies of atmospheric and oceanic data.
