Michael Mann. Great.
Ask him why the shepherd nomadic Genghis Khan led Mongol hordes bothered leaving Mongolia in the MWP.
Maybe because they were nomadic.
if its colder than predicted - its weather
Because those are short term predictions made days ahead by weathermen. Weather is less predictable in the short term than climate in the long term. Over a longer term (meaning years, not days) temperatures haven't been "colder than predicted".
if its the same temp as predicted - it shows "the models are right"
So?
if its warmer than predicted - OMG global warming!!!!
14 of the 15 hottest years on record have been this century. (The exception was 1998, an El Nino year.) 15 years is a longer term than weathermen deal with.
People do seem to understand the difference between short term and long term phenomena if it's a stock price we're talking about. I don't hear people asking "if Apple stock is rising, then what about the high prices during 2012?" as if it was the medieval warming period. But if it's a planet's temperature- "la la la la, fingers in my ears, I can't hear you!"
I see these two arguments being made over and over in these threads.
This one: "Correlation is not causation. So if something correlates, it means it's being caused by something else."
And this: "They're saying we're going to get more hurricanes? I guess they were driving SUVs and burning fossil fuels in 1667 when a hurricane hit Jamestown, Virginia, right? Huh? Huh?"
I don't remember a year as wet as this one in 30 years.
It seems a lot of Americans don't even realise how rain gets into the sky in the first place.
I learned this from the global warming skeptics:
Cons:
Ahh no. [posts link to site funded by ALEC, Exxon Mobil, and Richard Mellon Scaife] But yes keep telling yourself that the warm periods weren't global and miraculously just materialized where people could record it.
Ahh no., I didn't just tell myself.
How about we fix the climate models before using them to predict things?
How about these guys take into account the rising temperatures in oceanic heat reservoirs instead of restricting their analysis to lagging indicators like air temperature?
If they can't predict things, they can't predict things.
Can't argue with logic.
