This is called 'Turn Down the Heat: Why a 4°C Warmer World Must be Avoided' and is being hosted by Coursera. It is being well-presented by a selection of experts in the usual Coursera format. It is not a difficult course especially if you are familiar with the topic. Plenty of discussion. Recommended.
I am still hoping to see more Caribbean participants - only a small handful so far.

According to an opinion piece in the New York Times:
"More technology in the classroom has long been a policy-making panacea. But mounting evidence shows that showering students, especially those from struggling families, with networked devices will not shrink the class divide in education. If anything, it will widen it."Is this too negative - may be. Be we really have to look at the research and not just accept the very effective and motivating promotional hype coming from big tech companies whose main priority is simply to sell their services and hardware.

Looks like the same variety as mentioned previously.

report in Slate says:
"The only sound way to appraise the state of the world is to count. How many violent acts has the world seen compared with the number of opportunities? And is that number going up or down? As Bill Clinton likes to say, “Follow the trend lines, not the headlines.” We will see that the trend lines are more encouraging than a news junkie would guess."After examining the statistics the report concludes:
"The world is not falling apart. The kinds of violence to which most people are vulnerable—homicide, rape, battering, child abuse—have been in steady decline in most of the world. Autocracy is giving way to democracy. Wars between states—by far the most destructive of all conflicts—are all but obsolete. The increase in the number and deadliness of civil wars since 2010 is circumscribed, puny in comparison with the decline that preceded it, and unlikely to escalate."
