How much trouble is everything living on earth in because of Global Warming?

1. How much trouble are we in?
   For future generations, big trouble.
   The risks are much greater over the long run than over the next few decades, but the emissions that create those risks are happening now. Over the coming 25 or 30 years, scientists say, the climate is likely to resemble that of today, although gradually getting warmer. Rainfall will be heavier in many parts of the world, but the periods between rains will most likely grow hotter and therefore drier. The number of hurricanes and typhoons may actually fall, but the ones that do occur will draw energy from a hotter ocean surface, and therefore may be more intense, on average, than those of the past. Coastal flooding will grow more frequent and damaging.
   Longer term, if emissions continue to rise unchecked, the risks are profound. Scientists fear climate effects so severe that they might destabilize governments, produce waves of refugees, precipitate the sixth mass extinction of plants and animals in Earth’s history, and melt the polar ice caps, causing the seas to rise high enough to flood most of the world’s coastal cities.
   All of this could take hundreds or even thousands of years to play out, conceivably providing a cushion of time for civilization to adjust, but experts cannot rule out abrupt changes, such as a collapse of agriculture, that would throw society into chaos much sooner. Bolder efforts to limit emissions would reduce these risks, or at least slow the effects, but it is already too late to eliminate the risks entirely.

   Short Answers to Hard Questions About Climate...

   This is why if you are living in North America and aren't already living in Canada you might want to migrate there within the next 100 years or so. 

   For example, if you are in Asia anywhere near the Equator (unless you are at high altitude) you migth want to migrate north to Mongolia and Siberia which is where the weather will be much nicer within 100 years.

   Where don't you want to be living 100 years from now?

   Likely anywhere deserts and the equator meet without much water or tillable land. However, if you are really rich you still likely could live anywhere because you might be able to afford air conditioning. But, if you are exposed to the weather some places you might want to live underground to stay cooler especially during the days where it might be 150 degrees Fahrenheit or over 65 degrees Celsius. So, for most people you would need weather proof suits that might resemble underwater scuba divers in some ways to keep cool with refrigeration units to cool the air before you breathe it.

   However, above 95 degrees Fahrenheit or 35 degrees Celsius there is around a 23% drop in photosynthesis in all plants which means your crop yields when over 95 degrees Fahrenheit or 35 degrees Celsius are going to be 23% on average less than below this temperature.
