Work-in-progress... I'm using this as a "label" to gather American individuals and organizations who generally oppose attempts at addressing the global warming / climate change challenge. A primary primary criteria of inclusion are if the entities have made public statements that aim to cast doubts as to the reality of climate change, whether to express their genuine skepticism or for any other reason( tactic to delay action, to please electors tied to the fossil fuel economy...) Additional criteria include the support of legislation that impedes progress on the issue, strong connections with industries and organization with pro-carbon positions etc. While these criteria seem rather broad and loose, we do seek to only include entities that can exhibit a pattern of these "climate denial" behaviors. The "Start date" should be used to record the _most recent_ climate denial activity, as in "as of May 2018 the entity was still strongly against climate change mitigation". The "End date" is for when the entity stop these denial behaviors. This is not a true 'organization' is the sense of littlesis entities, just a loose association of persons or organization which generally can be classified as resisting action to address climate change.
