I simply offer up two quotes. One is an opinion of what will happen based on fiction, one is a statement of fact, hard data. The subject is global warming.
Statement One
One of the world's leading ice experts has predicted the final collapse of Arctic sea ice in summer months within four years. In what he calls a "global disaster" now unfolding in northern latitudes as the sea area that freezes and melts each year shrinks to its lowest extent ever recorded, Prof Peter Wadhams of Cambridge University calls for "urgent" consideration of new ideas to reduce global temperatures. --John Vidal, The Guardian, 17 September 2012
Note the year! What is interesting is that other experts were wheeled out by the BBC just last week to make the same sort of claims. It is just that the four years has been...er delayed.
Statement Two
Since hitting its earliest minimum extent since 1997, Arctic sea ice has been expanding at a phenomenal rate. Already it is greater than at the same date in 2007, 2008, 2010, 2011, 2012 and 2015. Put another way, it is the fourth highest extent in the last ten years. Even more remarkably, ice growth since the start of the month is actually the greatest on record, since daily figures started to be kept in 1987.
And here is the chart from the blog Not A Lot of People Know That. 
I would say "discuss" but if you are in a University "Safe Space" I would not since you will almost certainly be accused of offending some precious millennial and promptly face an exclusion order.
