To be consistent the survey question was about change in attitude towards global warming in the past 5 years.
No, my level of concern has not changed that I'm aware of.
I can't think of some event or discovery or report in the last 5 years that IMO would be basis for a change in concern.
Not much change in:
- basic science related to climate (that would be cause for more concern)
- trends in weather measurements (climate = trends or patterns of weather over say 30 years)
- extreme weather (it surprizes me how stable those trends are)
- climate models
- international agreements (Paris treaty)
- national progress on climate goals
- public attitudes / polling results - fairly stable
- IPCC reports
- Little change in climate research direction or funding for basic science
- Little change in funding levels for research on climate adaption, mitigation or energy technology
- Paris treaty - US president signs with questionable constitutional authorization
- Release of IPCC AR5 (Assessment Report # 5) in 2013
- Plans, pressure or actual early decommissioning of nuclear power plants - in some countries those plans have been reversed.
- Increasing awareness of the impact/possible importance of nuclear electrical power
- Increasing political polarization in western countries
- Possible increase of talk or threats to investigate or criminalize "climate change denial"
I think it's telling that of the over %45 of respondents who said they were more concerned ... zero or close to zero offered an explanation.
- Perhaps the numbers might be partly explained by a small sample size and a self-select audience.
- I assume that most of the respondents were familiar with the topic 5 years ago.
- The missing explanations might be understood in part as posters are used to responding with what related thoughts come to mind rather than addressing the topic posed in the initial post (a common practice in forums sometimes called "coat racking").
