Satisfying global demand for energy, food, and goods without emitting CO2 to the atmosphere is a central challenge of the 21st century.  My research is aimed at understanding the scale of that challenge and finding ways to meet it.
Global carbon uptake by cement carbonation
Nature Geoscience | November 21, 2016

Globally, carbonating cement materials are a large, overlooked and growing sink of CO2, which has offset 43% of the total process CO2 emissions (excluding those from related fossil energy inputs) from production of cement between 1930 and 2013.

Simulating the Earth system response to negative emissions
Environmental Research Letters | September 20, 2016

Earth system models suggest significant weakening, even potential reversal, of the ocean and land carbon sinks under future negative emission scenarios. Weakening of natural carbon sinks will hinder the effectiveness of negative emissions technologies and therefore increase their required deployment to achieve a given climate stabilisation target.

Global climate forcing of aerosols embodied in international trade
Nature Geoscience | September 9, 2016

In recent years, international trade has displaced radiative forcing related to aerosols such as black carbon, sulfate, nitrate and ammonium from developed, net-importing nations like the U.S. to emerging, net-exporting nations like China. We quantify this shift and discuss its policy implications.

Carbon lock-in: Types, causes, and policy implications
Annual Review of Envt. and Resources | September 2, 2016

Existing technologies, institutions, and behavioral norms together constrain the rate and magnitude of carbon emissions reductions in the coming decades. We review recent research on "carbon lock-in," the implications for decarbonization efforts, and propose a research agenda that can help bridge the gaps between science, knowledge and policy-making.

Quantifying expert consensus against the existence of a 'chemtrails' conspiracy
Environmental Research Letters | August 10, 2016

76 of the 77 (98.7%) scientists we surveyed had not encountered evidence of a secret, large-scale atmospheric spraying program, and said that purported evidence are more easily explained by well-understood physics and chemistry associated with aircraft contrails and atmospheric aerosols.
