Review: Implementation challenges of managed aquifer recharge in developing countries Open
Managed aquifer recharge (MAR) is a versatile approach that can help reduce vulnerability to climate change. In developing countries, where the need for adaptation is high, MAR often does not move beyond the experimental or piloting phase.…

The hard steps model and whole Earth-system transitions Open
The hard steps model is a ‘toy’ mathematical representation of evolution towards complex life on Earth or Earth-like planets. It assumes that, at the longest time scale, the rate of evolution towards increased complexity is governed by unl…

Seawater carbonate chemistry based carbon dioxide removal: towards commonly agreed principles for carbon monitoring, reporting, and verification Open
Carbon Dioxide Removal (CDR) from the atmosphere is unavoidable if we are to meet the Paris Agreement’s goal of limiting global warming to 1.5°C, and almost certainly required to limit warming to 2°C. The ocean exchanges carbon dioxide (CO…

A Comprehensive Analysis of Air‐Sea CO<sub>2</sub> Flux Uncertainties Constructed From Surface Ocean Data Products Open
Increasing anthropogenic CO 2 emissions to the atmosphere are partially sequestered into the global oceans through the air‐sea exchange of CO 2 and its subsequent movement to depth, commonly referred to as the global ocean carbon sink. Qua…

Rapid rise in the global ocean carbon sink determined from atmospheric oxygen observations Open
The rate of increase of atmospheric carbon dioxide (CO2) in recent decades is only about half that expected if all anthropogenic emissions had stayed airborne. The “missing” CO2 is absorbed by the oceans and land vegetation1. Of these two …

A water mass transformation method applied to diagnosing ocean carbon uptake Open
The ocean is a strong sink for anthropogenic CO2, absorbing around a quarter of emissions since the industrial era. Quantifying the ocean carbon sink is necessary for constraining the global carbon budget; however, discrepancies remain bet…

Enhanced northward ocean transport of anthropogenic carbon through recovery of overturning circulation may be affecting North Atlantic CO2 uptake efficiency Open
Of the additional carbon dioxide added to the atmosphere by human activities the ocean absorbs approximately a quarter, with a disproportionate fraction accumulating at depth in the North Atlantic due to the combined action of northward oc…

Overturning Pathways Control AMOC Weakening in CMIP6 Models Open
Future projections indicate the Atlantic Meridional Overturning Circulation (AMOC) will weaken and shoal in response to global warming, but models disagree widely over the amount of weakening. We analyse projected AMOC weakening in 34 CMIP…
