Global Warming vs. Other Causes of Shifts in Bird Ranges | The SPPI Blog

The South African scientists say their work suggests that either “observed climate changes have not yet been sufficient to trigger extensive shifts in the ranges of indigenous birds in this region, or that a priori assumptions are incorrect.” Either way, as they continue, “this study highlights the danger of naive attribution of range changes to climate change, even if those range changes accord with the predictions of climate-change models,” because “misattribution could distract conservationists from addressing pressing issues involving other drivers of biodiversity change such as habitat transformation, and obscure important lessons that might be learned from the dynamics that pertain to such changes.”

The Hockey Schtick: More ex-post "adjustments" to Satellite Sea-Level Altimetry

From a 2002 publication showing the Topex/Posiedon satellite altimetry sea level data for the eight years from 9/92-9/00, the global map shows stable to declining sea levels in most areas with the exception of the western Pacific, which is strongly influenced by periodic ENSO/El Nino/La Nina conditions.
