BC3 Journal Article “Anthropogenic ecosystem disturbance and the recovery debt”

Ecosystem recovery from anthropogenic disturbances, either without human intervention or assisted by ecological restoration, is increasingly occurring worldwide. As ecosystems progress through recovery, it is important to estimate any resulting deficit in biodiversity and functions. Here we use data from 3,035 sampling plots worldwide, to quantify the interim reduction of biodiversity and functions occurring during the recovery process (that is, the ‘recovery debt’). Compared with reference levels, recovering ecosystems run annual deficits of 46–51% for organism abundance, 27–33% for species diversity, 32–42% for carbon cycling and 31–41% for nitrogen cycling.

New Coal-Fired Plants Jeopardise Paris Agreement

Global greenhouse gas emissions need to peak soon and be reduced practically to zero in the second half of this century in order to not exceed the climate targets adopted in the Paris Agreement. However, there are currently numerous coal-fired power stations around the world at different stages of construction and planning that could be completed in the next decade. If all these plants are actually built, their expected future emissions will make it very difficult to reach these targets, even in an optimistic scenario with the deployment of carbon capture and storage technologies. Policy makers around the world need to react quickly and help to redirect investment plans for new coal-fired power stations towards low-carbon technologies

"Un verano sin hielo en el océano Ártico puede poner en riesgo los objetivos del Acuerdo de París". Un verano sin hielo en el océano Ártico puede poner en riesgo los objetivos del Acuerdo de ParísUn nuevo estudio muestra que la tendencia actual de derretimiento del hielo marino en el océano Ártico podría poner en peligro los objetivos del Acuerdo de París para hacer frente al cambio climático. Los autores del estudio concluyen que, debido a la futura reducción del albedo asociada al derretimiento del hielo marino, las emisiones globales de dióxido de carbono tendrían que reducirse a cero entre 5 y 15 años antes de lo previsto para poder alcanzar los objetivos establecidos por el acuerdo. También muestran que el objetivo de limitar el aumento de las temperaturas globales a 1.5 grados Celsius establecido por el Acuerdo de París sería inalcanzable sin emisiones de carbono “negativas”.

BC3 Journal Article “Mitigation implications of an ice-free summer in the Arctic Ocean”

The rapid loss of sea ice in the Arctic is one of the most striking manifestations of climate change. As sea ice melts, more open water is exposed to solar radiation, absorbing heat and generating a sea-ice–albedo feedback that reinforces Arctic warming. Recent studies stress the significance of this feedback mechanism and suggest that ice-free summer conditions in the Arctic Ocean may occur faster than previously expected, even under low-emissions pathways.
