van Vuuren, Detlef P.; et al. (2015): Implications of long-term scenarios for medium-term targets (2050)

van Vuuren, Detlef P.; van Sluisveld, Mariësse; Hof, Andries F. (2015): Implications of long-term scenarios for medium-term targets (2050). PBL Netherlands Environmental Assessment Agency.

Report with afforestation (3.5) and negative emissions (4). "If fast and substantial reduction of greenhouse gas emissions is postponed further, there are fewer options available to stay below a 2 °C warming at the end of the century. Delayed action is likely to require measures that remove CO2 from the atmosphere by planting forests and/or using bioenergy in combination with carbon capture and storage in order to meet the 2 °C target. The latter technique still involves considerable challenges. Climate policy decisions in the next years are therefore likely to have long-term implications."

Tomei, Julia; Helliwell, Richard (2015): Food versus fuel? Going beyond biofuels

Tomei, Julia; Helliwell, Richard (2015): Food versus fuel? Going beyond biofuels. In Land Use Policy. DOI: 10.1016/j.landusepol.2015.11.015 

"In this paper, we use the debate on food versus fuel as a lens to examine the interdependencies between the multiple end-uses of feedstocks and the multifunctionality of land. Revealing a more nuanced understanding of the realities of agricultural networks, land use conflicts and the values of the people managing land, we argue that the simplification achieved by food versus fuel, although effective in generating public resonance that has filtered into political response, has failed to capture much that is at the heart of the issue."

Legal Planet: Does the Paris Agreement Open the Door to Geoengineering?

"For these reasons, it appears to me, geoengineering begins to look necessary as a practical matter if we are going to hit such ambitious goals. Although it involves risks, the risks are less severe if we make a strong an effort as possible to cut emissions first, so that geoengineering doesn’t need to carry so much of the weight of emissions reductions."

BiologyWriter Blog: Can GeoEngineering Beat Global Warming?

"If the Paris accords fail, GeoEngineering may offer our last best hope for beating global warming… but there is much we do not yet know."

The Conversation: Paris emissions cuts aren’t enough – we’ll have to put carbon back in the ground

"To stabilise temperatures at any level, be it 1.5℃, 2℃ or even 3℃, net carbon dioxide emissions must be reduced to zero. Most governments, environmental groups and business leaders now understand this. And it is acknowledged, albeit implicitly, in Article 4 of the Paris agreement, which calls for greenhouse emissions to be “balanced” by carbon sinks some time after mid-century."

Care2: African Countries Pledge Enormous Reforestation Program

"A number of countries across the African continent have agreed to a monumental re-forestation program at the COP21 climate summit. Called AFR100, it’s goal is to restore 100 million hectares – or around 1,000,000 square kilometers – of pristine forest. For those counting, that’s larger area than France and the UK combined."

New Internationalist Blog: Geoengineering: a boon for big business not the environment

"The terms ‘net zero emissions’, ‘negative emissions’, ‘climate neutrality’ and ‘greenhouse gas emissions neutral’ are the current euphemisms for geoengineering.(vi) These terms are used in the COP21 negotiating text and are distinguished from decarbonisation and other terms that refer specifically to reducing fossil fuel use.(vii) They are bandied about as though the technologies to achieve zero or negative emissions are mature and proven. They are not even close, but geoengineering is an absolutely critical component to the fallacy of a business as usual solution to climate change."

Global Justice Ecology Project: No to 1.5oC with geoengineering!

"To achieve this, radical emissions cuts would be needed from now, but in the case of these countries, that’s not their real intention. Instead, behind the smokescreen of a more ambitious goal, there is a set of Trojan Horse technologies being proposed, collectively called “geoengineering”."

The Energy Collective: COP 21: A Pathway for 1.5°C

"A pathway that doesn’t involve future use of CCS would require net zero emissions in just 23 years – an option that isn’t even remotely feasible. Returning to the 40 year pathway, even this presents an immensely challenging task. While it might be feasible to have a zero emissions power sector in under 40 years, particularly given that all the necessary technologies to do so exist in one form or another, electricity still represents only 20% of final energy use."

Job: Risks to global water resources from geoengineering the climate with solar radiation management

"You will explore this by applying simulations from the latest geoengineering climate model experiments run in the Geoengineering Model Intercomparison Project (GeoMIP) to a global hydrological model. You will investigate spatial patterns of rainfall, flood risk, drought, and water stress, across the globe, under a set of scenarios of solar radiation management deployment. You will answer policy-relevant research questions such as: which parts of the globe will benefit/suffer from solar radiation management; which regions would be better off with global warming than with a cooler climate achieved by geoengineering; and how long would it take for such changes to occur; all within the context of global water resources."
