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，特别是化石燃料的燃烧和森林砍伐，推动了全球气候的变化，并且这种变化预计会加剧。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，分配和安全产生重大影响。由于气候变化，植物病毒的流行病学将在未来改变。大气二氧化碳含量升高，温度升高，水供应变化以及更频繁的极端天气事件，将通过宿主和媒介的变化对植物病毒产生直接和间接影响。预计的气候变化将影响植物病毒及其载体的分布和存活，预计在许多地理区域中会增加。此外，气候变化会影响植物病毒的毒力和致病性，从而增加疾病暴发的频率和规模。因此，需要对植物病毒流行病学有更多的了解，以更好地预测未来的挑战并制定有效而强大的控制策略，以帮助确保未来全球粮食生产。
