Heartland is a lobbying arm that funnels money from wealthy industrialists into the political and social spheres in an attempt to influence policy and public perceptions in the hope that such influence will ultimately aid in protecting the profits and markets of those industrial interests.
Just like government scientists are used to advance the vested interests of government. The main difference being the scale – the $5m pa (of its own money) that Heartland spends, being almost undetectable next what government spends (of the public’s money) on climatology alarmism.
