Hoegh-Guldberg, Ove; Northrop, Eliza; Lubchenco, Jane (2019): The ocean is key to achieving climate and societal goals. In: Science 365 (6460), S. 1372–1374. DOI: 10.1126/science.aaz4390.
„The just-released Intergovernmental Panel on Climate Change (IPCC) special report on the ocean and cryosphere in a changing climate (SROCC) (1) details the immense pressure that climate change is exerting on ocean ecosystems and portrays a disastrous future for most life in the ocean and for the billions of people who depend on it unless anthropogenic greenhouse gas (GHG) emissions are slashed. […] We highlight the report’s analysis of the mitigation potential and the required research, technology, and policy developments for five ocean-based mitigation areas of action: renewable energy; shipping and transport; protection and restoration of coastal and marine ecosystems; fisheries, aquaculture, and shifting diets; and carbon storage in the seabed (see the figure).[nbsp]“
Rogelj, Joeri; Huppmann, Daniel; Krey, Volker; Riahi, Keywan; Clarke, Leon; Gidden, Matthew et al. (2019): A new scenario logic for the Paris Agreement long-term temperature goal. In: Nature 573 (7774), S. 357–363. DOI: 10.1038/s41586-019-1541-4.
„The approach proposed here closely mirrors the intentions of the United Nations Paris Agreement, and makes questions of intergenerational equity into explicit design choices.“
Shindell, D.; et al. (2019): Climate and air-quality benefits of a realistic phase-out of fossil fuels
Shindell, Drew; Smith, Christopher J. (2019): Climate and air-quality benefits of a realistic phase-out of fossil fuels. In: Nature 573 (7774), S. 408–411. DOI: 10.1038/s41586-019-1554-z.
„Here we show that more realistic modelling scenarios do not produce a substantial near-term increase in either the magnitude or the rate of warming, and in fact can lead to a decrease in warming rates within two decades of the start of the fossil-fuel phase-out.“
„In an era of climate change, large-scale land acquisitions threaten to revive classic tactics of colonialism in new institutional forms.[nbsp]Countries[nbsp]and corporations – often[nbsp]working in concert[nbsp]– have been buying land around the world. The political implications of this slow transfer of the material means of critical resource security from the Global South to the Global North are vast and dire. They also complicate the politics of our responses to the climate crisis, which include the prospects for genuinely participatory carbon removal.“
„Some scientists suggest we could spray the stratosphere to help lower global temperatures. Critics say that’s a crazy idea, and much too dangerous to contemplate. Who decides, and how? How would we govern these technologies? What role should young people play in these decisions, now, and over the decades? Join C2G, with Pablo Suarez and Roop Singh from the Red Cross Red Crescent Climate Centre, in support of the UN Youth Climate Summit, for a thought-provoking game exploring some of the knottiest questions in climate – where nothing is certain, and time is counting down.“

„Jennifer Holmgren, chief executive of carbon recycling firm LanzaTech, explained modestly how the Chicago-based startup had cut multi-million-dollar deals on four continents, including in China, aimed at helping curb climate change and air pollution.“
