The new study found that those who report experience of flooding express more concern over climate change, see it as less uncertain, and feel more ①__________ that their actions will have an effect on climate change. Importantly, these perceptual (认知的) ②__________ also translate into a greater willingness to save energy to mitigate climate change. Previous psychological research suggests that many people are relatively unconcerned about climate change because they perceive it as a ③________ issue that will not directly affect them. But the authors of the new study say their results suggest that drawing ④_____ between local weather s and climate change is likely to be a useful strategy for increasing concern and action. An earlier study conducted after major U.K. floods in 1998 and 2000 found ⑤_________ similar levels of concern in those directly affected by flooding and those who did not have that experience. But given that ⑥________ severe flooding s struck England since 2003, the British research team decided to revisit the issue. Elke Weber — a professor of business and psychology at Columbia University — called the findings surprising and important. Following the failed climate change negotiations in Copenhagen, the ⑦_________ for sufficient public concern about climate change and political will to reduce carbon emissions have seemed dim. However, recent s in Tunisia (突尼斯), Egypt and other countries have shown that increases in the perceived effectiveness of individual and ⑧_________ action can change ⑨________ and behaviors quickly and ⑩___________. The new study’s findings, Weber added, provide a glimmer of hope that similar ‘tipping point’ dynamics might exist in the domain of climate change.
