The Heartland Institute skews the data by taking two points and ignoring all of the data in between, kind of like grabbing two zero points from sin(x) and claiming you're looking at a steady state function.
Playing devil's advocate: it's kinda like pointing out that the last 3 months have been the warmest on record in an attempt to convince people that there's a warming trend.
Single data points cannot be used to make an argument - on either side - even if you're actually right. Intellectual dishonesty on both sides of the debate has made global warming/climate change a toxic topic.
Work without a vision is slavery, Vision without work is a pipe dream, But vision with work is the hope of the world.
