As PG remarked in the comments, deniers have been oddly quiet about the opening ceremony in Rio de Janeiro. I'm not sure how popular the Olympic Games are in the USA. Still, I'm surprised that I haven't seen a WUWT conspiracy theorist link the opening ceremony to the 1992 Earth Summit in Rio, given their fear of the natural environment and their opposition to humans living in harmony with nature.
As Australia's ABC reported, the Games ceremony had a very strong message about climate change.
A rallying cry to save the planet from environmental destruction has launched the Olympic Games as Rio de Janeiro put on a glittering opening carnival.
The overwhelming theme of the evening was protection of the environment.
"It is not enough to stop harming the planet, it is time to start healing it," programme notes from the ceremony's organisers read...
...An early opening sequence depicted the birth of life, culminating in the sprouting of a green entanglement of leaves from the stadium floor depicting the Amazon rainforest.
Indigenous Brazilians then performed native dances before creating huge "Ocas" or native huts in the centre of the stage.
Yet the party mood was halted in its tracks by a sombre sequence titled 'After the Party' which used NASA scientific maps to warn of environmental crisis facing the planet, detailing rising sea levels to melting polar ice caps.
Huffington Post had this to say:
The Opening Ceremony at the Rio Olympics Friday evening was filled with celebrations of Brazilian culture and unity. But for a few brief moments, the message was polarizing and crystal clear: The world must do whatever it can to stop climate change.
I read that the program included Ed Hawkins graphic of the temperature spiral, too. Well done, Dr Hawkins.
