Changes in global climate driven by anthropogenic activities, especially the burning of fossil fuels and deforestation, have been progressively increasing and are projected to intensify. Increasing concentrations of atmospheric carbon dioxide and temperature will have significant consequences for future food production, quality, distribution and security. The epidemiology of plant viruses will be altered in the future as a result of climate change. Elevated atmospheric carbon dioxide, increased temperature, changes to water availability and more frequent extreme weather events will have direct and indirect effects on plant viruses through changes in hosts and vectors. Predicted climatic changes will affect the distribution and survival of plant viruses and their vectors, which are expected to increase in many geographic regions. Furthermore, climate change can affect the virulence and pathogenicity of plant viruses, consequently increasing the frequency and scale of disease outbreaks. Thus, greater understanding of plant virus epidemiology is needed to better anticipate challenges ahead and to develop effective and robust control strategies that will aid in securing global food production for the future.
人为活动引起的全球气候变化，特别是化石燃料燃烧和森林砍伐，正在逐步加剧，并预计将进一步恶化。大气中二氧化碳浓度和温度的升高将对未来的粮食生产、质量、分布和安全产生重大影响。由于气候变化，植物病毒的流行病学状况将在未来发生变化。大气中二氧化碳升高、温度升高、水分供应变化以及更频繁的极端天气事件将通过改变宿主和介体对植物病毒产生直接和间接的影响。预计气候变化将影响植物病毒及其介体的分布和存活，预计在许多地理区域，它们的数量将会增加。此外，气候变化还会影响植物病毒的毒力和致病性，从而增加疾病爆发的频率和规模。因此，需要更好地了解植物病毒的流行病学，以更好地预测未来的挑战，并制定有效的、强大的控制策略，以确保未来的全球粮食生产。
