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

"Ozeano Artikoan izotzik gabeko uda batek arriskuan jar ditzake Parisko Akordioaren helburuak".Ikerlan berri batek adierazi duenez, ozeano Artikoko itsas izotza urtzearen oraingo joerak arriskuan jar litzake klima-aldaketari aurre egiteko Parisko Akordioaren helburuak.
Ikerlanaren egileek ondorioztatu dutenez, itsas izotzaren urtzeak etorkizunean albedoaren gutxitzeak eragingo du. Honen ondorioz, karbono-dioxidoaren emisio globalak zerora murriztu beharko lirateke aurreikusitakoa baino 5 - 15 urte lehenago, akordioak ezarritako helburuak bete ahal izateko. Gainera, ikerketaren arabera, tenperatura globalen igoera 1,5 Celsius graduetara mugatzeko helburua, Parisko Akordioak ezarritakoa, karbono-emisio “negatiborik” gabe ezingo litzateke lortu.

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.

On-farm anaerobic digestion (AD) has been promoted due to its improved environmental performance, which is based on a number of life cycle assessments (LCA). However, the influence of site-specific conditions and practices on AD performance is rarely captured in LCA studies and the effects on C and N cycles are often overlooked. In this paper, a new model for AD (SIMSWASTE-AD) is described in full and tested against a selection of available measured data.
