„The Carbon Takeback Obligation (CTBO) is a new policy instrument that could ensure that CO2 from fossil energy no longer ends up in the atmosphere.“

„The effectiveness, feasibility, duration of effects, co-benefits, disbenefits, cost effectiveness and governability of four ocean-based negative emissions technologies (NETs) are assessed in comparison to eight other ocean-based measures.“

„We show that planting two native tree species (Betula pubescens[nbsp]and[nbsp]Pinus sylvestris), of widespread Eurasian distribution, onto heather (Calluna vulgaris) moorland with podzolic and peaty podzolic soils in Scotland, did not lead to an increase in net ecosystem C stock 12 or 39[nbsp]years after planting.“

„We performed face-to-face interviews using formal expert elicitation methods with 13 US and 13 Chinese climate experts randomly selected from IPCC authors or supplemented by snowball sampling. We compare their judgments on climate change, SG research, governance, and deployment.“

„Natural climate solutions (NCS) play a critical role in supporting the future of both climate and nature. Research conducted for this consultation report confirms estimates that NCS can provide one-third (close to 7 Gt CO2) of the climate mitigation to reach a 1.5- or 2-degree pathway by 2030—and at a lower cost than other forms of carbon dioxide removal.“
„Mann’s characteristic take-no-prisoners storytelling details fossil fuel persuasion tactics … and points to reasons to yet be hopeful.“

‚“Solutions to the global climate crisis must be bold and forward-looking but grounded in science,” said RCSA President [&] CEO Daniel Linzer. “In funding creative, high-risk ideas that emerge from the Scialog process, some ideas that may seem like flights of fancy can turn into reality.”‘

„Here, we highlight the main environmental risks of large‐scale tree planting and propose 10 golden rules, based on some of the most recent ecological research, to implement forest ecosystem restoration that maximizes rates of both carbon sequestration and biodiversity recovery while improving livelihoods. These are as follows: (1) Protect existing forest first; (2) Work together (involving all stakeholders); (3) Aim to maximize biodiversity recovery to meet multiple goals; (4) Select appropriate areas for restoration; (5) Use natural regeneration wherever possible; (6) Select species to maximize biodiversity; (7) Use resilient plant material (with appropriate genetic variability and provenance); (8) Plan ahead for infrastructure, capacity and seed supply; (9) Learn by doing (using an adaptive management approach); and (10) Make it pay (ensuring the economic sustainability of the project).“

„We present an idealized model of optimally-controlled climate change, which is complementary to simpler analytical models and more comprehensive Integrated Assessment Models. We show that the four methods of controlling climate damage– mitigation, carbon dioxide removal, adaptation, and solar radiation modification– are not interchangeable, as they enter at different stages of the causal chain that connects GHG emissions to climate damages.“
