๐งตIf you were ever curious about the effects of RCP8.5 on home runs . . .
Great example of how climate reductionism is itself causing bad science . . .
There is an obvious control group, AAA baseball (completely ignored in this new paper)
And home runs are down in AAA

Maybe climate change only has effects in the major leagues?
Silly science is still fun!
Climate change did not lead to more home runs in Japan 1977-2003
Attribution science is tricky like that

And climate change has not caused more home runs in NCAA D1 baseball
Climate attribution is a tricky business, I tell ya

So let me summarize the state of play
Climate changes causes more home runs in MLB
But it does not in AAA, Japan or NCAA D1
It took me all of 5 minutes to gather this data
On a more serious note,
Science? Peer review? Journalists?
WYD?
