A new report from the International Center for Tropical Agriculture. a funded by the Bill and Melinda Gates Foundation, found that West Africa, where half of the world's cocoa supply comes from, is becoming less and less suitable for cocoa production as climate change brings higher temperatures and changing rainfall patterns.
The report says that between 2030 and 2050 land suitable for cocoa production will be slashed dramatically, with production having to move to less suitable areas. This change will make a huge impact on the worldwide industry and hurt the local farmers who rely on cocoa crops for their livelihood.
Global demand for chocolate has been quickly rising as developing nations like China import more of it. The growing demand and drop in production will mean much higher prices for chocolate.
The study proposes finding new heat and drought resistant crops that could thrive in West Africa, while helping to transition cocoa production to more suitable areas.

And so true that the chocolate we consume isn't really chocolate!

Because of the term, many people believe 'global warming' would simply generally lead to a "warming" or increase in temperatures. This is only part of the big picture. There are more scary, wide-spread and severe consequences that would arise from weather change, shifts in rainfall patterns, stronger level storms (hurricanes, tornadoes, snow storms, floods, drought, ...) and more frequent occurrences of such radical weather.
This would wreak havoc on ALL types of ecosystems. It would make hot and arid places flood, or snow melt in colder areas several weeks ahead of time, or cause drought in a rainy lush green area. Do you see why this can not be solved with a genetic mutation or modification? Or 'synthetic food'? Climate change / global warming will increase faster with time - or geometrically. The more the atmospheric temperature increases, the faster it will increase and the faster changes will occur: a snowball effect. So - By the time we figure out what mutation or modification or adaptation to make, we would already be in big trouble.
Another important thing related to climate that people tend to forget: it is ot only the temperature that is shifting, but an ENTIRE ECOSYSTEM. This means that the insects will also shift or migrate based on what temperature, humidity, etc suits them. One of the major obstacles to succesful farming and crop cultivation - without which we would starve to death - is PESTS. We have long battled insects / 'pests' for our food. Insects tend to breed more and spread more with increased temperatures. Some insects that are not naturally found in colder (or higher up or lower down the equator) areas, do not have natural predators.
We should really look at the big picture. There is a balance that should not be tipped.
I think this article is interesting because it targets something we love - Chocolate - to show us one small possible impact of global warming. It takes the topic close to the heart of readers.

There are several solutions. The obvious one is to expand cropping in similar climates elsewhere. There are vast areas in PNG, Vanuatu, Irian Jaya, Sumatra which have suitable climates. This would have the effect of introducing competition into the supply chain as well and would help to keep the price of cocoa down.
Another alternative is to genetically modify the crop or isolate the genes in the cocoa plant so that they can be inserted into another more tolerant plant.
Another possibility is to create synthetic cocoa. Bacteria could be modified to secrete cocoa precursors. It doesn't really matter where chocolate comes from, as long as it is chocolate.
As it is currently, most of the chocolate sold to consumers could hardly be called real chocolate anyway, since it is adulterated by industrial manufacturing processes which aim to eke maximum profits.
