Relax. The chicken thread will remain so. It is just easy to do, when the weather effects raising our birds. Pretty broad topic really.nor for me -- but the question asked was, how far back do directly-measured global temperature records go, and the answer is, 1850. that is NOT the sum total of data on climate change, but this does not seem like the right forum to flood with this topic. but there are lots and lots of other forms of data (tree ring measurements, analysis of ice cores, paleogeologic data, etc) that all show a strikingly rapid climate shift going on, more or less since the Industrial Revolution began and wildly accelerating since the 1950s or so. if interested, feel free to PM me (I'm an environmental studies professor).
back to chickens, please!
The way I see it, it will not really matter. Human behavior will not change unless it absolutely has to. Just human nature. Unfortunately. I do not think anyone will convince Southeast Asia to slow down, or South America. And I do not think we will quit driving our vehicles 600 miles a week.
And I realize that was not the total sum of data. I just still do not think there is enough quite yet, but I was just illustrating a point. I think it was understood.
