Dedicated to the balanced discussion of global warming
Plenty Magazine – May 23, 2007
This is a sad article if it is true. Evidently several species of frogs have become extinct and some scientists believe that this extinction was caused by global warming. While I am well aware that certain amphibians (esp. frogs) are very susceptible to changes in their environment, I am concerned that this article does not live up to the burden of proof.
A few of my concerns:
While it is likely that some scientist has looked into these fairly obvious questions, I could not find any background that alleviated my concerns.
Global warming is the top suspect for the disappearance of 17 amphibian species from Costa Rican jungles
Five of the amphibian species were found only in Costa Rica, meaning their disappearance from the country’s jungles spells extinction, said Alvaro Herrero, a biologist with Costa Rica’s National Biodiversity Institute.
Scientists have yet to identify a precise mechanism for the disappearance of the amphibians, which began decades ago, but a prime suspect is a fatal fungus that has invaded their habitats
Several studies in recent years have linked the rapid disappearance of many of the world’s frog and toad species to global warming.
Scientists say the amphibian die-off is a harbinger of things to come in the biologically rich tropical forests of Costa Rica.
“It’s going to be a fact that we see a large extinction,” said Rodrigo Gamez, president of the biodiversity institute.
The precise reason for the La Selva decline is not known, but scientists suspect that higher temperatures are inhibiting plant growth and thus diminishing the volume of decomposing leaves in which the amphibians thrive.
