The ice structure of Antarctica has altered, as have the winds and ocean currents between that ice mass and southern lands in the southern hemisphere. I can not cite academic or scientific sources to verify my opinion here, just speculation from some scientists. The science is woefully behind the unfolding of the events. It has been for decades. One example: 15 years ago it was extremely hard to find any mention of permafrost melting releasing methane into the atmosphere and very little information was offered as to what effects such a release might cause. That permafrost would melt was acknowledged, but methane release was not mentioned.
Computer modeling has been and remains even more flawed. There is also speculation that La Nina will return and that the deforestation of the Amazon will alter or change rainfall patterns in South America (and probably globally). My purpose here is too offer my *opinion* that the chances of further future frost events in coffee growing regions have been greatly increased. Imagine how the price of coffee will react if there are more frosts? I would guess that coffee will continue to get upside support as long as any weather forecasts call for colder than normal temperatures, no?
