Why Dana1981 hasn't proved climate disruption

Arguments by Motl vs What the Science Says
"Climate sensitivity is low"

Net positive feedback is confirmed by many different lines of evidence.

"Climate's changed before" Climate reacts to whatever forces it to change at the time; humans are now the dominant forcing.
"Earth hasn't warmed as much as expected" This argument ignores the cooling effect of aerosols and the planet's thermal inertia.
"It's the sun"

In the last 35 years of global warming, sun and climate have been going in opposite directions

"Lindzen and Choi find low climate sensitivity"

Lindzen and Choi’s paper is viewed as unacceptably flawed by other climate scientists.

"Solar Cycle Length proves its the sun" The sun has not warmed since 1970 and so cannot be driving global warming.
"There is no consensus"

97% of climate experts agree humans are causing global warming.

"There's no tropospheric hot spot"

We see a clear "short-term hot spot" - there's various evidence for a "long-term hot spot".
