Wow! The EPA website features a webpage about global warming using a slideshow by climate denier Richard Linzen which is packed with old, well-debunked climate misinformation epa.gov/environmental-… h/t @bud_ward
He commits the false dichotomy fallacy arguing CO2 lagging temp in the past disproves greenhouse warming. This is debunked at sks.to/lag, (Denial101x MOOC) & (Cranky Uncle) 
He argues that ocean cycles could be causing observed warming, despite the fact that they only move heat around while the planet is building up heat (at a rate of over 4 atomic bombs per second). skepticalscience.com/global-warming…
There's single cause fallacy in that old chestnut "climate has always changed so it must be natural", debunked at sks.to/past, (Denial101x), & (Cranky Uncle)
He misrepresents the tropospheric hot spot as a signature of greenhouse warming when it's the result of *any* type of warming - debunked at sks.to/hotspot & (Denial101x)
Much more, including a lot of ranting about consensus (recommend reading sks.to/consensus, sks.to/coc, & the Story of Climate Consensus for an overview of this topic).
