I'm not sure where you read that in the article I provided. However, since it is a prediction, and the nature of a prediction doesn't lend itself to absolute certainty, I dont know why you see this as significant.
- is there climate change occurring?
Yep.
- is it significant compared to the past?
Define significant.
- is 150 years of measurable data accurate in terms of alltime global weather/climate changes?
We have more than 150 years of data. It isn't clear why more than this is needed to determine that human activity is causing a warming trend though.
- what percentage of climate changes are due to man-made behaviors? What exact behaviors?
The website I linked talks about contributions from other sources, such as solar irradiance, which it says cannot plausibly be responsible for more than 10% of the 20th century warming. The website says that human activity accounts for most of the changes.
- is there anything that can actually be done world wide to minimize the alleged damage?
If so what? How would we “make” people/countries follow suggestions?
This is not relevant to whether or not anthropogenic climate change is real, so why are you asking this if you don't believe it?
- what is the alleged recommendations impact on human population, economies, etc?
This is not relevant to whether or not anthropogenic climate change is real, so why are you asking this if you don't believe it?
- what are the agendas, money sources, data manipulations that have been seen on both sides of the debate?
I can't account for every source of funding surrounding this debate. If you have evidence that there is a worldwide scientific conspiracy then let's see it.
- why is the issue being so politicized, especially with the “we are gonna die in 12 years” side which has been making these claims since the late 70s (global cooling, acid rain, global warming, etc) and have been proven wrong nearly every time?
This is just not true. Just because some politicians or the media make ridiculous claims doesn't mean that is what the scientific literature says. This is a common rhetorical trick in this debate. Regardless, it's fallacious reasoning to conclude that someone must be wrong now because they were wrong previously.
