To date, numerous studies have looked at think tanks and networks involved in the climate change counter-movement in the US. Now, for the first time, the most important contrarian climate change think tanks in Europe have been studied systematically. The study whose first author, Núria Almiron, is a researcher with the UPF Department of Communication, covers a 24-year period (1994-2018) and takes account of the messages issued in six European countries, in four languages.
