Expert review of the science underlying nature-based climate solutions - Nature Climate Change  (Mar 20) |
|
Mar 20 · Viable nature-based climate solutions (NbCS) are needed to achieve climate goals expressed in international agreements like the Paris Accord. Many NbCS pathways have strong scientific foundations and can deliver meaningful climate benefits but effective mitigation is undermined by pathways with less scientific certainty. Here we couple an extensive literature review with an expert elicitation on 43 pathways and find that at present the most used pathways, such as tropical forest conservation, have a solid scientific basis for mitigation. However, the experts suggested that some pathways, many with carbon credit eligibility and market activity, remain uncertain in terms of their ... Read more ... |

Global trend of methane abatement inventions and widening mismatch with methane emissions - Nature Climate Change  (Mar 18) |
|
Mar 18 · Substantially reducing methane emissions is the fastest way to repress near-term warming and is an essential prerequisite for reaching the 1.5?°C target. However, knowledge about the global invention trend, sectoral and national distribution and international diffusion of methane-targeted abatement technologies (MTATs) remains limited. On the basis of patent data, we identify more than 175,000 MTAT inventions applied between 1990 and 2019 by 133 countries or dependent territories. Our results revealed that after sustained growth of more than fourfold, the number of global high-quality MTAT inventions declined by 3.5% annually from 2010 to 2019. The sectoral and national-level ... Read more ... |

Historical impacts of grazing on carbon stocks and climate mitigation opportunities - Nature Climate Change  (Mar 14) |
|
Mar 14 · Grazing has been associated with contrasting effects on soil carbon stocks at local scales, but accurate global assessments of its net impact are lacking. Here we conducted a meta-analysis of 1,473 soil carbon observations from grazing studies to quantify global changes in soil carbon stocks due to grazing practices. Our analysis shows that grazing has reduced soil carbon stocks at 1-m depth by 46?±?13 PgC over the past 60?years. The interplay between grazing intensity and environmental factors explains global variations in soil carbon changes. Maps of optimal grazing intensity indicate that implementing grazing management on 21 million km2 of grazing lands, mainly through ... Read more ... |

The emerging human influence on the seasonal cycle of sea surface temperature - Nature Climate Change  (Mar 14) |
|
Mar 14 · Gaining insight into anthropogenic influence on seasonality is of scientific, economic and societal importance. Here we show that a human-caused signal in the seasonal cycle of sea surface temperature (SST) has emerged from the noise of natural variability. Geographical patterns of changes in SST seasonal cycle amplitude (SSTAC) reveal two distinctive features: an increase at Northern Hemisphere mid-latitudes related to mixed-layer depth changes and a robust dipole pattern between 40°?S and 55°?S that is mainly driven by surface wind changes. The model-predicted pattern of SSTAC change is identifiable with high statistical confidence in four observed SST products and in 51 ... Read more ... |
