• From clouds to carbon:
    land-atmosphere interactions
    in the spotlight


    Understanding the interface between the land and the atmosphere has been an important component of IGBP’s research. Here we highlight three recent contributions that resulted from research sponsored by the Integrated Land Ecosystem–Atmosphere Processes Study (iLEAPS).

  • Coastal megacities:
    risks and opportunities


    Every year, more and more people are flocking to live near the sea’s edge, often congregating in massive cities. Sophie Blackburn and Mark Pelling explore what happens when urban and coastal zones collide.

Global Change Magazine No. 79

This issue highlights various aspects of Arctic climate change, including sea ice and methane. We also look at a new tool for analysing complex global challenges, the path ahead for the Earth-system science community and the aftermath of Rio+20.

The following feature articles from this issue


can be read on-line.

Methane: Not a damp squib, not yet a time bomb
Although Arctic methane sources deserve careful monitoring, there is no reason to panic just yet.

A silver lining to Arctic clouds?
Marine microbiota are the key to a negative feedback that could slow down the melting of Arctic sea ice.

Mapping a planet under pressure
DebateGraph moves away from linear narratives and provides a new way of analysing complex global challenges.

A Rio retrospective
A realistic assessment of Rio+20 points to some limited but significant successes, not least for IGBP.

Earth-system science at a crossroads  
The path ahead should combine the need for wider engagement with a continuing commitment to reason.

Zooming in over the northern latitudes  
The European Space Agency is working with global-change researchers to better understand Eurasian boreal regions.
