on the planet. Coastal enclaves, in which ~40% of the world's population lives, are in jeopardy of having to move inland...and farmers are seeing reduced yields on their crops due to higher temperatures. The cause is understood...i.e. the burning of our very finite store of Fossil Fuels for Heat and Power. Note that according to sources like British Petroleum the world has 47 yrs of Proven Oil Reserves remaining...we need to save those FFs for all the other uses we rely on them for.
Time to take action...at least for those who are able to plan ahead.
