Forest fragmentation may be releasing much more carbon than we think

By Morgan Erickson-Davis31 March 2017 (Mongabay) – The earth’s forests have been broken into around 50 million fragments, the edges of which add up to a length that would make it a third of the way to the sun and which increase annual tropical deforestation carbon emissions by 31 percent. This, according to a new […]

Rising temperatures increased conflicts and deadly violence in the ancient Maya world

By Léa Surugue31 March 2017 (International Business Times) – With temperatures set to rise in the coming decades, investigating the issue of whether climate change can exacerbate conflict is becoming more and more relevant. Looking at how past civilisations fared in the face of changing climatic conditions offers interesting insights. In a research now published […]

Scientists foresee sharp rise in deadly heat stress as global temperatures climb – “Because the response is nonlinear, for each fraction of a degree the climate warms, the increase in heat stress is ever greater”

27 March 2017 (Loughborough University) – In December 2015, the international community pledged to limit global warming to below 2°C to prevent dangerous climate change. However, new analysis suggests that even if this target is met, the dangers to society posed by heat stress are likely to escalate. Writing in the Proceedings of the National […]

Sub-ice phytoplankton blooms in Arctic Ocean increasing rapidly as sea ice thins – “The meter decline in sea ice thickness in the Arctic in the past 30 years has dramatically changed the ecology”

By Leah Burrows29 March 2017 (Harvard Gazette) – In 2011, researchers observed something that should be impossible — a massive bloom of phytoplankton growing under Arctic sea ice in conditions that should have been far too dark for anything requiring photosynthesis to survive. So, how was this bloom possible? Using mathematical modeling, researchers from the […]

Curbing emissions with a new “carbon law” – “Alarming inconsistencies remain between science-based targets and national commitments”

23 March 2017 (Stockholm Resilience Centre) – An international team of researchers led by centre director Johan Rockström propose a solution for the global economy to rapidly reduce carbon emissions. The authors argue a carbon roadmap, driven by a simple rule of thumb or “carbon law” of halving emissions every decade, could catalyse disruptive innovation. […]

Arctic sea ice maximum at record low for third straight year – Antarctic minimum lowest in the satellite record

22 March 2017 (NSIDC) – Arctic sea ice appears to have reached its annual maximum extent on March 7. This is the lowest maximum in the 38-year satellite record. NSIDC will post a detailed analysis of the 2016 to 2017 winter sea ice conditions in our regular monthly post in early April. On 7 March […]
