After two weeks of closed door negotiations, a U.N. preparatory committee has failed to reach consensus on a global plan of action, titled “The Future We Want,” to be adopted by a summit meeting of world leaders mid-June in Brazil.

The results provide an important benchmark for monitoring the impact of environmental change on the population of this iconic bird, which breeds in remote areas that are very difficult to study because they often are inaccessible with temperatures as low as -58 degrees Fahrenheit. Recently reporting in the journal PLoS ONE, an international team of scientists describe how they used Very High Resolution satellite images to estimate the number of penguins at each[...]
