Potential progression of significant events

If progression towards the global climate change crisis continues at the current rate (which is currently probably negative in growth), then the following significant events may occur in the next century, possibly in this order (in my amateur opinion):

- Worldwide flooding
- Scarcity of clean water
- Massive phytoplankton die-off
- Privatization of water
- Scarcity of food
- Militarization of public spaces
- Mass migration towards poles
- Collapse of global economy (or civilization)
- ?

Naturally, rain cycles will change with worldwide oceanic hyperthermia. Clean water sources will be contaminated by floods, while an exponential die-off of phytoplankton will set off a world-wide chain reaction whose scale has never seen by humankind. During this time, water will somehow be purchased by corporations, who will even claim rainwater as their own. Scarcity of food will follow, caused by economic and ecological stress. Sudden disruption of the modern paradigm will lead to unrest, followed, perhaps preemptively by a militarization of many first world countries (many third world countries have already reached this point today.) Since food and related services both maintain population and economy, the lack thereof would certainly lead to an economic decline on a worldwide scale. Humans would follow food, security and economy to the poles, which would lead to a global collapse of first world civilization as we know it.
At this point, our only salvation would include assistance from another intelligence, sudden helpful mystery technology, evacuation, or extinction. Good luck.
