Rothamsted’s aphid-resistant wheat – a turning point for GMOs?
<p>Abstract</p> <p>Rothamsted Research mounted a successful counter-campaign in response to a threat by environmental protesters to destroy their research project examining aphid-resistant genetically modified (GM) wheat. This involved the use of online media, petitions, and other tools, by which researchers engaged directly with media and the general public in defense of their work. Lessons are suggested for other researchers in the controversial field of GM plant breeding.</p
Gene editing achieves consistently higher favorability in social and traditional media than GMOs
ABSTRACTWhile GMOs have been the subject of negative discourse over a long time period, it is possible that newer breeding technologies like gene editing are viewed more favorably. We present data for a 5-year period between January 2018 and December 2022, showing that in content specific to agricultural biotechnology, gene editing achieves consistently higher favorability ratings than GMOs in both social and traditional English-language media. Our sentiment analysis shows that favorability is especially positive in social media, with close to 100% favorability achieved in numerous monthly values throughout our 5 years of analysis. We believe that the scientific community can therefore be cautiously optimistic based on current trends that gene editing will be accepted by the public and be able to achieve its promise of making a substantial contribution to future food security and environmental sustainability worldwide. However, there are some recent indications of more sustained downward trends, which may be a cause for concern
Greater than 99% consensus on human caused climate change in the peer-reviewed scientific literature
While controls over the Earth’s climate system have undergone rigorous hypothesis-testing since the 1800s, questions over the scientific consensus of the role of human activities in modern climate change continue to arise in public settings. We update previous efforts to quantify the scientific consensus on climate change by searching the recent literature for papers sceptical of anthropogenic-caused global warming. From a dataset of 88125 climate-related papers published since 2012, when this question was last addressed comprehensively, we examine a randomized subset of 3000 such publications. We also use a second sample-weighted approach that was specifically biased with keywords to help identify any sceptical peer-reviewed papers in the whole dataset. We identify four sceptical papers out of the sub-set of 3000, as evidenced by abstracts that were rated as implicitly or explicitly sceptical of human-caused global warming. In our sample utilizing pre-identified sceptical keywords we found 28 papers that were implicitly or explicitly sceptical. We conclude with high statistical confidence that the scientific consensus on human-caused contemporary climate change—expressed as a proportion of the total publications—exceeds 99% in the peer reviewed scientific literature
Infilled Ditches are Hotspots of Landscape Methane Flux Following Peatland Re-wetting
Peatlands are large terrestrial stores of carbon, and sustained CO2 sinks, but over the last century large areas have been drained for agriculture and forestry, potentially converting them into net carbon sources. More recently, some peatlands have been re-wetted by blocking drainage ditches, with the aims of enhancing biodiversity, mitigating flooding, and promoting carbon storage. One potential detrimental consequence of peatland re-wetting is an increase in methane (CH4) emissions, offsetting the benefits of increased CO2 sequestration. We examined differences in CH4 emissions between an area of ditch-drained blanket bog, and an adjacent area where drainage ditches were recently infilled. Results showed that Eriophorum vaginatum colonization led to a “hotspot” of CH4 emissions from the infilled ditches themselves, with smaller increases in CH4 from other re-wetted areas. Extrapolated to the area of blanket bog surrounding the study site, we estimated that CH4 emissions were around 60 kg CH4 ha−1 y−1 prior to drainage, reducing to 44 kg CH4 ha−1 y−1 after drainage. We calculated that fully re-wetting this area would initially increase emissions to a peak of around 120 kg CH4 ha−1 y−1, with around two-thirds of the increase (and 90% of the increase over pre-drainage conditions) attributable to CH4 emissions from E. vaginatum-colonized infilled ditches, despite these areas only occupying 7% of the landscape. We predicted that emissions should eventually decline toward pre-drainage values as the ecosystem recovers, but only if Sphagnum mosses displace E. vaginatum from the infilled ditches. These results have implications for peatland management for climate change mitigation, suggesting that restoration methods should aim, if possible, to avoid the colonization of infilled ditches by aerenchymatous species such as E. vaginatum, and to encourage Sphagnum establishment
Indemnifying against flood loss in a changing environment
The UK – as with all other parts of the globe - is faced with new environmental uncertainties, particularly from climate change. Factors which threaten its existing flood loss indemnity regime regarding damage to property include greater ecological awareness on the part of policy makers, pressures to limit public commitments to flood defence, and the growing technical ability of insurers to distinguish risk exposure across particular locations. Current reliance on the commercial insurance market is called into question, as general levels of insurance availability and affordability come under threat. Problems of take-up among particular groups will be exacerbated by more restricted availability or terms of cover which are likely increasingly to affect vulnerable individuals and communities. The changing law and policy environment involves challenges to the delicate public-private balance which has underpinned the current arrangements and has implications both for civil society and the insurance industry, as well as informing the extent to which alternative approaches might offer solutions
