text: issues and re-constructing them diﬀerently. By comparing the persistent words used related to the two 
  discourses in the 10-year period in Table 2, we think that global warming showed a relative preference 
  toward general descriptions or slogans, such as “earth” and “pollution”, whereas “climate change” 
  was more associated to speciﬁc issues like “solar”, “coal”, “china”, and “food”. 
  
  Studies have suggested that the public shows a preference for scientiﬁc publications with general 
  keywords compared with those with complicated scientiﬁc jargon [47], lacking a deep understanding of 
  the complicated issue [46] and the necessity for mitigation of the climate issue [47]. These conclusions 
  seem to suit global warming more than climate change according to the current study, which is 
  probably because climate change receives more publicity and recognition than global warming in the 
  scientiﬁc community. In the association network shown in Figure 2, global warming was found to be 
  more connected with temperature abnormalities. This ﬁnding is in accordance with studies reporting 
  that short-term temperature anomalies [87] can increase the public’s belief about global warming by 
  increasing the understanding of this abstract issue [88], although scientists mostly make judgments 
  based on long-term weather statistics [89]. However, none of the four words, “snow”, “summer”, 
  “winter”, or “heatwave” in the temperature theme of global warming were ranked in the top 50 nodes 
  list of the climate change network.
