Come on, it’s bleedin’ obvious that financial and budgetary restrictions are not the real reason for the withdrawal of the future Brazilian government to host the next UN conference on climate change.
International repercussion aside, such a conference would also be an issue on national television networks and other media. As a consequence it would raise attention and push some kind of public discourse. And that, again, would not amuse some people with a lot of influence on Brazilian politics, especially certain lobbyists.
For them, prevention means to keep a lot of heads buried in the sand.
