Rockström, Johan; et al. (2017): A roadmap for rapid decarbonization

Rockström, Johan; Gaffney, Owen; Rogelj, Joeri; Meinshausen, Malte; Nakicenovic, Nebojsa; Schellnhuber, Hans Joachim (2017): A roadmap for rapid decarbonization. In Science 355 (6331), pp. 1269–1271. DOI: 10.1126/science.aah3443.

Including negative emissions/BECCS. "Complemented by immediately instigated, scalable carbon removal and efforts to ramp down land-use CO2 emissions, this can lead to net-zero emissions around mid-century, a path necessary to limit warming to well below 2°C."

San Diego Union-Tribune: Climate change: Trump’s dramatic move deserves dramatic response

"Another Union-Tribune op-ed by Jane C.S. Long — until recently the associate director for energy and environment at Lawrence Livermore National Laboratory — outlines a plausible approach to taking on global warming that doesn’t require Trump’s approval. Long strongly supports conventional attempts to reduce greenhouse-gas emissions. But she notes that even if all emissions stopped immediately, “mankind has already ‘bought’ a thousand years of climate change.”"

San Diego Union-Tribune: Warming up to new solutions? Our world is in need of fixes

"While the world debates commitments to reduce the emission of greenhouse gases (mitigation), staying below a 2 degree Celsius increase in temperature has become unlikely. There could come a time when mankind considers “geoengineering” to intentionally cool the planet and try to avoid the worst impacts of climate change." By Jane C. Long

Gunderson, Ryan; et al. (2017): Ideological obstacles to effective climate policy. The greening of markets, technology, and growth

Gunderson, Ryan; Stuart, Diana; Petersen, Brian (2017): Ideological obstacles to effective climate policy. The greening of markets, technology, and growth. In Capital & Class 2 (7), 030981681769212. DOI: 10.1177/0309816817692127.

"In light of the 2015 Paris Climate Agreement, this project synthesizes and advances critiques of the possibility of a sustainable capitalism by adopting an explicit ‘negative’ theory of ideology, understood as ideas that conceal contradictions through the reification and/or legitimation of the existing social order. Prominent climate change policy frameworks – the ‘greening’ of markets (market-corrective measures), technology (alternative energy, energy efficiency, and geoengineering), and growth (the green growth strategy) – are shown to conceal one or both of the two systemic socio-ecological contradictions inherent in the current social formation."

Mathias, Jean-Denis; et al. (2017): On our rapidly shrinking capacity to comply with the planetary boundaries on climate change

Mathias, Jean-Denis; Anderies, John M.; Janssen, Marco A. (2017): On our rapidly shrinking capacity to comply with the planetary boundaries on climate change. In Scientific reports 7, p. 42061. DOI: 10.1038/srep42061.

"Here, we use the DICE model to analyze the set of adaptive climate policies that comply with the two planetary boundaries related to climate change: (1) staying below a CO2 concentration of 550 ppm until 2100 and (2) returning to 350 ppm in 2100. Our results enable decision makers to assess the following milestones: (1) a minimum of 33% reduction of CO2 emissions by 2055 in order to stay below 550 ppm by 2100 (this milestone goes up to 46% in the case of delayed policies); and (2) carbon neutrality and the effective implementation of innovative geoengineering technologies (10% negative emissions) before 2060 in order to return to 350 ppm in 2100, under the assumption of getting out of the baseline scenario without delay."

Fischer, Severin (2017): Climate Policy After Paris: Inconvenient Truths

Fischer, Severin (2017): Climate Policy After Paris: Inconvenient Truths. Edited by Christian Nünlist (CSS Analyses in Security Policy, 203).

"The Paris Agreement of December 2015 fundamentally realigned the structures of international climate policy. At the same time, global targets and national measures are diverging. One direct implication is the need to consider new technology options."

Phys.org: Renewables can't deliver Paris climate goals: study

The study itself does not include NETs/BECCS systematically. "Expansion of renewable energy cannot by itself stave off catastrophic climate change, scientists warned Monday. Even if solar and wind capacity continues to grow at breakneck speed, it will not be fast enough to cap under two degrees Celsius (3.6 degrees Fahrenheit), the target set down in the landmark 2015 Paris climate treaty, they reported in the journal Nature Climate Change."

EconoTimes: Don't fall into the trap of restarting last decade's 'climate wars'

"In the run-up to Donald Trump’s inauguration, many climate experts are expressing concern that his views and those of his senior appointees are at odds with mainstream climate science. They’re grimly preparing to re-enter the fray of last-decade’s “climate wars”, which saw scientific knowledge about global warming come under intense and sustained attack."

the guardian: ‘A cat in hell’s chance’ – why we’re losing the battle to keep global warming below 2C

"A global rise in temperature of just 2C would be enough to threaten life as we know it. But leading climate scientists think even this universally agreed target will be missed. Could dramatic action help?"

Sanderson, Benjamin M.; Knutti, Reto (2016): Delays in US mitigation could rule out Paris targets

Sanderson, Benjamin M.; Knutti, Reto (2016): Delays in US mitigation could rule out Paris targets. In: Nature Climate change. DOI: 10.1038/nclimate3193.

"Political upsets could stall coordinated international mitigation action, but emissions and investments over the next few years will have long-term consequences. Any delays to mitigation or cuts to renewable energy research by the US will likely render the 2 °C target unachievable if a global precedent is set. [...] The only alternative would be an overshoot in temperature and negative emissions thereafter. Research in negative emissions should therefore be a priority, but near term policy should work under the assumption that such technology would not be available at large scale and low cost soon."
