Climate change impacted coffee prices. A large number of investors poured into the market.

It is reported that the main global coffee producing areas, including Brazil, have greatly reduced their production due to the impact of climate change, and coffee prices are likely to soar in the future. However, the price of coffee will not rise sharply this year at least.

Several of these factors seem to be driving up coffee prices: an outbreak of a disease called leaf rust in Central America. The disease, which is thought to be linked to climate change, has hit production in the main coffee producing area. Prolonged drought and unusually cold weather have caused Vietnam, the world's second-largest coffee producer, to lower its harvest forecast for Robbosa beans, which is mainly used to produce instant coffee. In addition, the rainfall in the coffee-producing areas of East Africa is also seriously insufficient.

But a series of events in Brazil involving climate change may be the main factor causing traders in international markets to raise prices sharply. As the world's largest coffee grower, Brazil accounts for about 40% of global coffee production. The state of Minas Gerais, located in southeastern Brazil, accounts for about 25% of the country's coffee production. Rainfall in December 2013, January and February 2014 was only 10 per cent of normal levels, while temperatures rose well above average. The non-governmental organization Coffee and Climate says the weather in Minas Gerais has been extremely unusual in recent months. For many coffee growers, this extreme weather is a disaster.

According to commodity experts, coffee production in Minas Gerais is likely to fall by as much as 35% this year, while total production of Arabica coffee beans in Brazil is likely to fall by 18%. As the global demand for coffee continues to soar in recent years, farmers are scrambling to plant more coffee trees. And these saplings are the most vulnerable to water shortage. In addition to yield, coffee farmers and traders are also concerned that adverse weather may affect the quality of coffee beans.

Brazil's climate model has been undergoing considerable changes in recent years. Drought and increasingly unstable weather patterns will hit large parts of Brazil. Coffee production around the world is likely to decline as temperatures rise, according to a new report released by the Intergovernmental Panel on Climate change (IPCC).

As the most popular type of coffee, the price of Arabica beans on the world market has climbed to about $2 per pound, nearly double that of a year ago. For consumers, however, the price of coffee is unlikely to rise this year. Most large coffee shops tend to buy coffee in the so-called futures market, that is, they usually lock in the current purchase price years in advance. In addition, there was a bumper harvest of coffee beans last year, and traders are still storing large quantities of coffee beans. But there are signs that a large number of speculators are rushing into the market.
