More Dead Toad Studies: Global Warming Didn't Kill Rainforest Toads
Read here. An exceptionally irritating and false assertion from the IPCC and climate alarmists is the one regarding species extinctions by the thousands, and more surely to come, all due to global warming. The classical example of this biased assertion is that the tropical Costa Rican toad's extinction was due to AGW. Unfortunately for the warming hystericals, recent actual science proved global warming innocent of the deaths.
A new group of researchers have revisited the dead toads' story, and again their new research finds that "global warming" is not the culprit. It's just more evidence that global warming alarmistas are totally 'clue'-less.
"Anchukaitis and Evans say their analysis suggests that "the cause of the specific and well-documented extinction of the Monteverde golden toad was the combination of the abnormally strong ENSO-forced dryness and the lethality of the introduced chytrid fungus, but was not directly mediated by anthropogenic temperature trends.....The two researchers report that "contrary to interpretations of the short instrumental record, no long-term trend in dry season hydroclimatology can be inferred from our δ18O time series at Monteverde." Instead, they find that "variability at the interannual scale dominates the isotope signal, particularly during the period of increased ENSO variance since the late 1960s," and they add, in this regard, that "there is no evidence of a trend associated with global warming." Hence, they emphasize that "the extinction of the Monteverde golden toad appears to have coincided with an exceptionally dry interval caused by the 1986-1987 El Niño event," which they describe as "one of the longest driest periods in the last 100 years," based on their δ18O chronology. In addition, they report there is currently no consensus on how anthropogenic climate change might influence the El Niño Southern Oscillation, while indicating that "ENSO anomalies in the most recent decades are not beyond the range of natural variability during the instrumental period"
