500 feet thick at the thin edge of the wedge…..3,000 feet thick at the other end of the wedge. [NOTE: Our 80 foot boat is in the lower left corner.] Miles long, 1-1/2 miles wide….. And not the biggest one of the 350 glaciers living in the park…. Perito Moreno is stunning as it is also serving as one of the “miner’s canaries” for global climate change. A central part of the national park for more than 100 years it has been extensively studied, measured, cross sectioned, photographed, and mapped for those 100 years. As such, it provides a good baseline, albeit a big baseline, for the changes occurring in the world’s temperatures, precipitation, and seasonal changes. People, the flat-earth society members, can deny climate change is occurring. We need not debate it to consider that all of the measures proposed to address it should be done anyway, whether climate change is occurring or not. I have seen no measure proposed that doesn’t stand on its own merits. That said, addressing climate change can be seen as an insurance policy–a relatively small payment today to avoid the cost of calamity later. Usually that calamity never occurs, like say the highly unlikely event that your house burns down, but we still happily buy fire insurance. So, Moreno glacier is the only of Argentina’s hundreds of glaciers that is not getting smaller. There is a lot of debate as to why. But what about the hundreds of others that are shrinking? Do we ignore that fact? Is it coincidence or does it correlate with the other changes occurring around the world that individually and collectively suggest our global house is on fire…. And we do not have another house to go to…. We saw Moreno in two seasons in 2 hours: Fall and Winter. Blowing freezing rain or Autumnal sun and long shadows….. Which would you prefer?
