Perceptions of enhanced weathering as a biological negative emissions option

Perceptions of enhanced weathering as a biological negative emissions option

This paper addresses the social acceptability of enhanced weathering, a technology that would involve spreading silicate particles over terrestrial surfaces in order to boost the biological processes that currently sequester CO2 as part of the earth's natural carbon cycle. We present the first exploration of British attitudes towards enhanced weathering, using an online survey (n = 935) of a re...

Negative CO2 emissions via enhanced silicate weathering in coastal environments

Negative emission technologies (NETs) target the removal of carbon dioxide (CO2) from the atmosphere, and are being actively investigated as a strategy to limit global warming to within the 1.5-2°C targets of the 2015 UN climate agreement. Enhanced silicate weathering (ESW) proposes to exploit the natural process of mineral weathering for the removal of CO2 from the atmosphere. Here, we discuss...

Biological weathering of sepiolite clay mineral as affected by the activity of an earthworm species )Eisenia foetida(

Sepiolite is an Mg-rich fibrous clay mineral which occurs in agricultural soils of arid regions. Although many investigations have been carried out on the formation and stability of this clay mineral, no information is yet available on the mineralogical changes of this mineral by earthworms. Therefore, this study was conducted to examine the effect of Eisenia foetida earthworms on sepiolite wea...

Enhanced rock weathering: biological climate change mitigation with co-benefits for food security?

Enhanced chemical weathering and organic carbon burial as environmental recovery factors of the OAE2; a case study in the Koppeh-Dagh Basin (NE Iran)

A late Cenomanian-early Turonian interval (Hamam-ghaleh section) adjusted with the transition of Aitamir and Abderaz formations has been investigated in the east of Koppeh-Dagh Basin to examine environmental perturbations related to the oceanic anoxic event 2. The dark shale of the upper Aitamir Formation indicate higher organic matter concentrations especially in the two intervals at the end o...
