In the past couple of hours, my social media feeds have *exploded* with loudly expressed perspectives on the Paris Climate Agreement.
How many of those expressing a perspective have read the Agreement?
I am guessing that is a number approaching zero.
The agreement is short, as far as government documents go, and you can read it for yourself here.
What does the Paris Climate Agreement actually do?
Read the text for yourself. It is a voluntary set of guidelines, with no enforcement provisions, for self reporting the steps each country will take and what they think they will accomplish. Out of 196 countries, none would ever cheat or bias the information they provide, of course.
If all of the voluntary measures were undertaken, various modeling groups estimate it may reduce global average temperature by between 0 and 0.36 deg C by 2100, if the climate change hypothesis is correct and all other factors remain the same. The Agreement says the goal is to limit temperature rise to 2 deg C over what it was about 150 years ago (or perhaps 1.5 deg C) at a cost of about $10 Trillion in present value terms just for the financial transfer from developed nations to developing nations and not including costs of developing alternatives for developed nations.
Countries choose their own “baseline” for emissions (China chose its model projected emissions in 2030 as its baseline whereas the U.S. chose 2005) and then voluntary measure their progress towards their self selected targets.
Dr. James Hansen, “father of climate change” said

“It’s a fraud really, a fake,” he says, rubbing his head. “It’s just bullshit for them to say: ‘We’ll have a 2C warming target and then try to do a little better every five years.’ It’s just worthless words. There is no action, just promises.

Update: From the science journal Nature (May 22, 2017):

Better out than in
 
Continued US membership in the Paris Agreement on climate would be symbolic and have no effect on US emissions. Instead, it would reveal the weaknesses of the agreement, prevent new opportunities from emerging, and gift greater leverage to a recalcitrant administration.

A lot of emotion will be vented on social media over an agreement that most have not read, do not understand, and which the “father of climate change” says is a worthless agreement and the science journal Nature says is “symbolic and have no effect on US emissions”.
From the above short summary we can see that there are both pros and cons of the Agreement.
Why such a strong emotional response on social media?
The answer is propaganda. Rather than examining the underlying documents, almost everyone is responding in terms of what they think they know, which they learned from propaganda messaging. Remember, propaganda is messaging targeted at a group for the purpose of getting others to adopt someone’s agenda. A wide variety of methods are used to persuade a group to adopt someone’s agenda (appeal to authority, get on the bandwagon, name calling, are a small sampling of the methods used here).
Many people have been “trained” to what they should “believe” or accept as truth. They now feel it is their responsibility to evangelize their “beliefs” to others, via social media.
But most are virtue signalling that they are “on the bandwagon” and do not realize the Paris Agreement appears to accomplish little positive. The point of the Agreement seems to be to enable a group to say we agree but to not actually agree to anything.
