1) They're guilty of many things, but complacency isn't one of them.
2) GHGs are not created equal. There's a reason all the models show that co2 is so much more dangerous than any other. Despite the relatively low irradiative absorption/reflection, co2 stays in the atmosphere for far longer than methane or water vapor. As a result, it has far more time to influence climate subsystems and sustain positive feedbacks. The only reason we're worried about GHG emissions is climate sensitivity, which is basically entirely a matter of magnitude of the feedback parameter.
It doesn't really matter. Methane is a short-lived GHG. It's not integral to all ecosystems the way that co2 is nor is it suspected of being climate forcing through cloud dynamics, effects on atmospheric water vapour, and other climate subsystems.
3) My mother's side of the family is from the west (Colorado). My uncle is an agronomist who consults with farmers about their crops and the biggest is corn. It wasn't anything particularly bad. I was out there this summer.
4) That isn't a debate. We're pouring GHGs into the atmosphere, so we're causing warming and I don't know of single scientist who disagrees. And as the earth has warmed so little in 15 years that we're below all model predictions, nobody thinks that we are responsible for all observed temperature trends since 1951 either. The question is simply what actions should be taken and why.
1) I think they are being complacent. The UN produced their eye-opening Livestock's Long Shadow' report in 2006 warning of the harm being caused to the environment by livestock production, everything from greenhouse gas emissions, deforestation, soil erosion etc etc. They've hardly been shouting it from the rooftops since.
The report said 18% of greenhouse gas emissions are caused by livestock production. Another source said they overestimated and it should be 14.5% and another source again said they underestimated and it should be 51%.
Whichever way you look at it it is way more than all forms of transport combined. The Livestock Industry is wholly unsustainable at the present rate, never mind with 40% more people by 2050 and the millions more people tapping into the 'meat and dairy' system in the emerging economies.
Growth of the livestock industry is going to totally undermine other green initiatives.
2) I don't know what point you're trying to argue there, but you're wide of the mark.

3) Not according to my retired farmer friend in Texas who told me things were much down and with an increased risk of corn 'ear mould'.
Looking on a farmer's network website corn harvest is better than expected but "Overall corn harvest in the northern half of the Corn Belt is still significantly behind the five year average."
And last year there was a widespread drought and still is I believe in many places, which is the point I'm making. Crops are hostage to the weather. Weather fluctuations can spell disaster for crop harvests.
4) I agree with you on that (though some people are still disputing it.)
We are negatively impacting on climate and we're trashing the planet.
There are solutions though I fear humankind is not willing to make the sacrifices and changes required...
Most people have become totally detached from the notion of Mother Earth and the connectivity of all life upon it.
