CST: Guess What Didn’t Kill the Golden Toad

Yet another bite taken out of the climate alarmists theories religion

The golden toad was last seen in 1989 in the Costa Rican cloud forest of Monteverde–and 5 years later, its disappearance was the first extinction to be blamed on humanmade global warming. New evidence, however, suggests that humans may not have been at fault after all.

Of course, it was blamed on CO2, Man is evil, man is bad, Man is guilty of being overwrought and hysterical and seriously jumping to conclusions. Wait, what?

But it’s hard to tell if the unusually dry conditions that contributed to the extinction were part of a natural cycle or connected to global climate change patterns. That’s because reliable temperature and moisture data for the Monteverde forests go back only to the 1970s. And due to the tropical climate, trees in Monteverde don’t form the rings usually used to study temperature and moisture patterns over time.

Ah, so those “professional scientists” were basically guessing? The hell you say!

Instead, Columbia University climate scientist Kevin Anchukaitis and paleoclimatologist Michael Evans of the University of Maryland, College Park, took samples the diameter of a pencil from two trees in the region. The duo then sliced the samples just 200 microns thick–about the width of a human hair–and analyzed them in a mass spectrometer to see what kind of oxygen isotopes they contained. Isotope ratios associated with dry conditions alternated with wetter conditions, allowing the researchers to establish the annual moisture cycle. The time-consuming analysis–there were 2000 pieces of wood to look at–created a climate record for the forest going back a century, which they describe online today in the Proceedings of the National Academy of Sciences.

“We expected to see some kind of trend related to global warming, yet when we developed the record it turned out the strongest trends were El Niño-related,” says Anchukaitis, referring to the cyclical weather pattern that affects rainfall and temperatures on the Pacific coast of North America. In Monteverde, El Niño caused an unusually severe dry season at about the time the golden toad was wiped out.

You have to give these researchers an A for honesty, particularly since the end of the article shows that they are pretty much alarmists. They expected it to be man’s fault, and, when they determined it wasn’t, but that pesky Mother Nature, they still published. Granted, as the story goes, their sample was small, and the field of oxygen isotope measurement is new, but, which makes more sense: nature and its 4 billion year history of mucking around, or Mankind, which contributes CO2 concentrations of around 3.4% of the 3.6% total atmospheric CO2 of the 2% of atmospheric greenhouse gases?
