This study explores how public attitudes across three countries influence support towards terrestrial enhanced weathering, whereby silicate minerals are applied to agricultural land to remove carbon dioxide from the atmosphere. An online survey was administered in Australia (N = 1000), the UK (N = 1000), and the USA (N = 1026) where there are ongoing field trials of this technique. Findings are similar across all three countries with many participants unfamiliar with enhanced weathering and unsure about supporting the use of enhanced weathering. Results show that positive affect is the main predictor for support of this technique, along with perceived benefits and level of concern about climate change. Open-ended questions asking why respondents would or would not support the use of enhanced weathering elicit mainly affective concepts, with enhanced weathering seen by individual respondents as either something mainly positive or mainly negative, with others saying it sounds risky and/or would have impacts on the environment. The way in which enhanced weathering is communicated is likely to influence support of the use of this strategy so must be undertaken carefully. Overall, our findings show that it is imperative to continue to engage the public, thereby allowing their views to be incorporated as enhanced weathering technology develops over time.

这项研究探讨了三个国家的公众态度如何影响对陆地增强风化的支持，从而将硅酸盐矿物应用于农田，以从大气中清除二氧化碳。在澳大利亚（N  = 1000），英国（N  = 1000）和美国（N = 1026），该技术正在进行现场试验。在这三个国家中，发现都是相似的，许多参与者不熟悉增强的风化作用，并且不确定是否支持使用增强的抗风化作用。结果表明，积极的影响是支持该技术的主要预测因素，同时还包括人们对气候变化的感知收益和关注程度。不限成员名额的问题，询问为什么受访者会或不会支持使用增强的耐候性引发主要的情感概念，个别受访者将增强的耐候性视为主要是积极的或主要是消极的，其他人则说这听起来有风险和/或会产生影响在环境上。传达增强的耐候性的方式可能会影响对使用此策略的支持，因此必须谨慎进行。总体而言，我们的研究结果表明，必须继续与公众互动，从而随着增强的耐候技术的发展，将他们的观点纳入其中。
