Links: Melting glaciers, floods, and species responses to climate change

1) BBC News – Rivers of ice: Vanishing glaciers.- David Breashears retraced the steps of early photographic pioneers such as Major E O Wheeler, George Mallory and Vittorio Sella – to try to re-take their views of breathtaking glacial vistas.

2) Thai water management experts are blaming human activity.for turning an unusually heavy monsoon season into a disaster. NYTimes writes:

The main factors, they say, are deforestation, overbuilding in catchment areas, the damming and diversion of natural waterways, urban sprawl, and the filling-in of canals, combined with bad planning. Warnings to the authorities, they say, have been in vain

3) Chen et al’s conducted a metanalysis of published species response to ongoing climate change and found 2-3X faster movement than previous studies.  Their paper in Science – Rapid Range Shifts of Species Associated with High Levels of Climate Warming (DOI: 10.1126/science.1206432) estimated median rates of species movement were 11m gain in elevation/ decade and poleward movement of 17 km/ decade. They conclude:

average rates of latitudinal distribution change match those expected on the basis of average temperature change, but that variation is so great within taxonomic groups that more detailed physiological, ecological and environmental data are required to provide specific prognoses for individual species.

Brisbane floods: before and after

From Australian Broadcasting Company the Brisbane floods: before and after:

High-resolution aerial photos taken over Brisbane last week have revealed the scale of devastation across dozens of suburbs and tens of thousands of homes and businesses.

The aerial photos of the Brisbane floods were taken in flyovers on January 13 and January 14.
