As the climate warms, all species will either need to find new habitats with similar temperatures to those they currently occupy or evolve new thermal tolerances. Recent research by Araujo and colleagues suggests that some species may be able to adapt to new, higher temperatures better than others...

Worldwide, about 800 million people lack access to an improved water source. In its most basic form, an improved water supply is a well or protected spring that protects water from outside contamination. Lack of access to clean water helps explain why15% of all deaths of children under 5 worldwide...

A new study by Alexander Stine and Peter Huybers offers strong evidence that reduced light availability (“global dimming”) explains the apparent lack of tree-ring evidence in many Arctic regions for the recent warming observed in instrumental records there. Dendroclimatology uses measurements of...

Renewable energy-based grids of the future face technical challenges on a large scale, the most obvious of which is the intermittent nature of most renewable sources of power: Solar and wind power both vary throughout daily and yearly cycles, while both are subject to highly unpredictable weather...

Loss of mass from ice sheets contributes to rising sea level. To understand the contributions of ice-sheets to sea level rise we must understand the spatial and temporal variability of ocean-driven melting, which has accelerated over recent decades.  Dutrieux and colleagues used observations and...

Changing people’s carbon emission patterns requires first understanding the differences in behaviors and corresponding emissions levels between different groups of people. A recent paper by Chancel in the journal Ecological Economics investigated the differences in carbon emissions between...

Transportation sector greenhouse gas reductions do more than save energy: greener public transportation alternatives can reduce traffic congestion, lessen US dependence on foreign oil and make the US more economically competitive. In addition to these benefits, policies that reduce GHG emissions by...
