我们分析了 2011 年 12 月至 2014 年 11 月期间美国各地发生的 10,748 起天气事件对气候变化关注的影响。通过量化每次事件发生期间当地有关气候变化的推特消息的相对增加量来衡量关注度。沿海洪水、干旱、山火、强风、冰雹、酷暑、严寒、大雪等事件都产生了明显的影响。与活动开始前相比，活动开始后的注意力确实更高。与天气事件相关的经济损失对注意力产生了积极而显着的影响，尽管影响很小。与当地历史活动相比，每次天气事件发生的异常也是一个重要的预测因素。特别是，与过去的研究一致，温度的相对异常（局部变暖）引起了人们对气候变化的关注。相比之下，风速可以预测对气候变化的绝对关注程度。这些结果可用于预测战略气候传播对气候变化的短期关注，并更好地预测长期气候政策支持。
We analyzed the effects of 10,748 weather events on attention to climate change between December 2011 and November 2014 in local areas across the USA. Attention was gauged by quantifying the relative increase in Twitter messages about climate change in the local area around the time of each event. Coastal floods, droughts, wildfires, strong wind, hail, excessive heat, extreme cold, and heavy snow events all had detectable effects. Attention was reliably higher directly after events began, compared to directly before. Financial damage associated with the weather events had a positive and significant effect on attention, although the effect was small. The abnormality of each weather event’s occurrence compared to local historical activity was also a significant predictor. In particular and in line with past research, relative abnormalities in temperature (local warming) generated attention to climate change. In contrast, wind speed was predictive of attention to climate change in absolute levels. These results can be useful to predict short-term attention to climate change for strategic climate communications and to better forecast long-term climate policy support.
