11. Podcast: Measuring methane above the Arctic

This week in the Planet Earth podcast, Michelle Cain of the University of Cambridge and Stéphane Bauguitte of the Facility for Airborne Atmospheric Measurements explain how and why they're measuring methane in the atmosphere above the Arctic - a region that's warming twice as fast as anywhere else on our planet.

12. CryoSat-2 mission reveals major Arctic sea-ice loss

Arctic sea ice volume has declined by 36 per cent in the autumn and 9 per cent in the winter between 2003 and 2012, a UK-led team of scientists has discovered.

13. Arctic tree takeover risks carbon release

Trees colonising formerly open tundra as the climate warms could cause Arctic ecosystems to release vast amounts of stored soil carbon into the atmosphere, a new paper argues.

14. Ice mission shows precise changes in Arctic sea-ice thickness

Scientists have produced the first map which shows the changes in the thickness of Arctic sea ice through the entire winter season. The map is the most accurate and extensive yet.

15. Scientists call for better management of the deep sea

The deep sea is in trouble. A recent study has found that it's being damaged by human activities, and that this is only likely to get worse. Scientists are now calling for better management and conservation of entire deep-sea ecosystems.

17. The rise and rise of the sea

Meticulous sea-level research at Southampton University's School of Ocean and Earth Science (SOES) suggests that large long-term sea-level rise is coming our way unless we take drastic action soon. Eelco Rohling tells us what this projection is based on.

18. Coral bleaching? The picture's not black and white

Problems with how scientists communicate with the media and in how reefs' health is assessed have created a skewed public understanding of coral bleaching, according to a new study.

19. CryoSat-2 data reveals Arctic ocean circulation

Scientists have used data from the European Space Agency's (ESA) ice mission, CryoSat-2 to create the first complete map of ocean circulation in the Arctic.
