Pope Francis' call for change respecting environmental issues will largely fall on deaf ears in the west, because we are a fat, stupid, spoiled people. ["Belch!"]
Here's an example of the problem facing us.
As the global atmospheric inventory of carbon compounds goes up, up, up, up due to human activity, the currents transfer heat generated by the gas increase to the polar regions, where all of the ice is, so that every 1 degree increase in ocean temp at the equator yields a 4 degree degree increase at the poles.
Greenland, and Antarctica, and all other land-bound ice on Earth, are melting faster and faster and faster.
The annual increase in ocean depth is becoming measurable with an ordinary ruler. No joke.
Now, the average modal elevation of cities like Miami above sea level is 6 feet.
Skeptics would say, "HO, HO, HO, YOU POOR IDIOT, IF THE OCEANS ARE INCREASING IN DEPTH BY, SAY, 1/32 OF AN INCH PER YEAR, IT WILL TAKE [72 INCHES x 32] YEARS, OR 2,304 YEARS, TO DROWN MIAMI ! HO, HO, HO !"
But it doesn't work like that.
6 feet in elevation is a numerical average running from 0.00 feet at the beach to a peak of 12 feet at the highest statistically-significant point.
In Miami's case, we can represent the slope running from the Atlantic beaches on the east to the western edges of the metropolitan area 10 miles to the west as a right triangle with a base of 633,600 inches and a height of 144 inches on the left side and 0.00 inches on the right side.
If we divide the base by the height, we get 633,600 inches / 144 inches = 4,400. See illustration ...
What that actually means is, For every additional 1 inch in ocean depth from global ice melt, the beach where the waves are crashing every minute in good weather moves inland by about 4,400 inches, or about 400 feet.
Now that 400 feet assumes a perfectly flat up-slope from the beach.
But it doesn't work like that. What's really going to happen is that at some points, the water is going to be coming inland a full mile with the first 1 inch increase in ocean depth.
And what that means is that within 20 years, there are going to be calls to evacuate southern Florida, and all of this ...
... will have a value of $ 000,000,000,000.01.
That's what we're facing, on all 3 coasts of the continental united States.
