Phys.org: Why we can't reverse climate change with 'negative emissions' technologies

"Featured prominently in the report is a discussion of a range of techniques for removing dioxide from the air, called Carbon Dioxide Removal (CDR) technologies or negative emissions technologies (NETs). The IPCC said the world would need to rely significantly on these techniques to avoid increasing Earth's temperatures above 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, compared to pre-industrial levels."

Yu, Q. (2018): Direct capture of CO2 from ambient air using solid sorbents

Yu, Q. (2018): Direct capture of CO2 from ambient air using solid sorbents. Enschede: University of Twente. DOI:10.3990/1.9789036546300

"In this thesis, a novel process is developed and experimentally demonstrated, for CO2 capture from ambient air to produce CO2 enriched air to enhance microalgae cultivation. First, an amine functionalized sorbent is selected, initially based on its water and CO2 equilibrium adsorption capacity. Subsequently, the selected sorbent is characterized on its stability under different conditions for a wide range."

Stephenson, S.; et al. (2018): Climatic Responses to Future Trans-Arctic Shipping

Stephenson, S.; Wang, W.; Zender, C.; Wang, H.; Davis, S.; Rasch, P. (2018): Climatic Responses to Future Trans-Arctic Shipping. In: Geophys. Res. Lett. 75 (2), S. 300. DOI: 10.1029/2018GL078969.

"Here we investigate impacts of shipping emissions on Arctic climate using a fully coupled Earth system model (CESM 1.2.2) and a suite of newly developed projections of 21st‐century trans‐Arctic shipping emissions. We find that trans‐Arctic shipping will reduce Arctic warming by nearly 1 °C by 2099, due to sulfate‐driven liquid water cloud formation. Cloud fraction and liquid water path exhibit significant positive trends, cooling the lower atmosphere and surface."

Harvard University Blog: Reflections on the IPCC special report on pathways to and impacts of 1.5°C

"The main difference to previous reports issued by the Intergovernmental Panel on Climate Change (IPCC) is that this report focuses on the 1.5°C target, while the the Fifth Assessment Report did not pay much attention to it, largely because too few studies even addressed this ambitious scenario. The Paris Agreement and the request to the IPCC for this latest special report have changed this: more and more studies have considered how the goal could be achieved – with similar results, but greater urgency."

MacMartin, D. G.; et al. (2019): The Engineering of Climate Engineering

MacMartin, D. G.; Kravitz, B. (2019): The Engineering of Climate Engineering. In: Annu. Rev. Control Robot. Auton. Syst. 2 (1). DOI: 10.1146/annurev-control-053018-023725.

"While reducing anthropogenic greenhouse gas emissions remains the most essential element of any strategy to manage climate change risk, it is also in principle possible to directly cool the climate by reflecting some sunlight back to space. Such climate engineering approaches include adding aerosols to the stratosphere and marine cloud brightening. Assessing whether these ideas could reduce risk requires a broad, multidisciplinary research effort spanning climate science, social sciences, and governance."

Science: Key climate panel, citing impending crisis, urges crash effort to reduce emissions

"A report released yesterday in Incheon, South Korea, by the Intergovernmental Panel on Climate Change (IPCC) says allowing the planet to warm by more than 1.5°C could have dire consequences, and that a speedy transformation of the world’s energy systems is needed to avoid breaching that limit, which is notably tighter than the target of 2°C cited in the Paris agreement of 2015. “Net [carbon dioxide] emissions at the global scale must reach zero by 2050,” said Valérie Masson-Delmotte, a climate scientist at France’s Alternative Energies and Atomic Energy Commission in Paris and a key participant in drafting the report."
