Wood-based biochar for the removal of potentially toxic elements in water and wastewater: a critical review
Sabry M. Shaheen,Sabry M. Shaheen,Nabeel Khan Niazi,Nabeel Khan Niazi,Noha E.E. Hassan,Irshad Bibi,Irshad Bibi,Hailong Wang,Daniel C.W. Tsang,Yong Sik Ok,Nanthi Bolan,Jörg Rinklebe,Jörg Rinklebe +12 more
TL;DR: In this paper, the potential use of wood-based biochar (WB) for the removal of potentially toxic elements (PTEs) from water and wastewater has been discussed, and a review demonstrates the overarching scientific opportunities for a comprehensive understanding of using WB as an emerging biosorbent and a promising low-cost and effective material for the remediation of contaminated water.

Applications of biochar in redox-mediated reactions.
Yong Yuan,Nanthi Bolan,Antonin Prévoteau,Meththika Vithanage,Jayanta Kumar Biswas,Yong Sik Ok,Hailong Wang +6 more
TL;DR: The abiotic and microbial applications of biochars as electron donors, electron acceptors, or electron shuttles for pollutant degradation, metal(loid)s (im)mobilization, nutrient transformation, and discuss the underlying mechanisms are reviewed.

Mahtab Ahmad,Anushka Upamali Rajapaksha,Jung Eun Lim,Ming Zhang,Nanthi Bolan,Dinesh Mohan,Meththika Vithanage,Sang Soo Lee,Yong Sik Ok,Yong Sik Ok,Yong Sik Ok +10 more
TL;DR: Due to complexity of soil-water system in nature, the effectiveness of biochars on remediation of various organic/inorganic contaminants is still uncertain.

Irreversible climate change due to carbon dioxide emissions
TL;DR: The climate change that takes place due to increases in carbon dioxide concentration is largely irreversible for 1,000 years after emissions stop, showing that thermal expansion of the warming ocean provides a conservative lower limit to irreversible global average sea level rise.

The contentious nature of soil organic matter
Johannes Lehmann,Markus Kleber +1 more
TL;DR: It is argued that the available evidence does not support the formation of large-molecular-size and persistent ‘humic substances’ in soils, and instead soil organic matter is a continuum of progressively decomposing organic compounds.

Global and regional drivers of accelerating CO2 emissions
Michael R. Raupach,Gregg Marland,Philippe Ciais,Corinne Le Quéré,J. G. Canadell,Gernot Klepper,Christopher B. Field +6 more
TL;DR: Global emissions growth since 2000 was driven by a cessation or reversal of earlier declining trends in the energy intensity of gross domestic product (GDP) and the carbon intensity of energy (emissions/energy), coupled with continuing increases in population and per-capita GDP.
