Gulp: Climate Change May Be Causing a Global Coffee Shortage

10 percent of Brazil’s most productive coffee-growing regions may be fallowed in just a few years.

If there was ever a reason to rise up in support of a benevolent climate-obsessed world dictator, this could be it.

Climate change has already taken the Winter Olympics, your Eggos, and the McDonald’s dollar menu, and now it’s coming for your coffee, too.

An epic drought—Brazil’s worst in decades—is threatening exports from the world’s largest coffee exporter and driving up wholesale prices worldwide. We’ve officially entered the realm of bloggers’ worst-case scenario.

Now, let’s not get too hasty. The world is not going to run out of coffee next week. Analysts still estimate an increasingly tight global coffee surplus of less than 1 percent of total production through the remainder of the year. But the Brazilian drought is causing a significant pressure on global supplies, and when coupled with burgeoning demand from increasingly affluent consumers in Asia (and Brazil itself), that means prices are surging and that surplus could quickly become a shortage if the drought continues to intensify. Arabica coffee futures are up more than 50 percent in just the last two months in response.

The current run on coffee is an example of the kinds of follow-on effects to be expected as the climate warms and rainfall patterns become more erratic. The ongoing lack of rainfall, coupled with record high temperatures across the whole of southeast South America during the current Southern Hemisphere summer, is just the kind of extreme weather event that’s been becoming more common over recent years. In an era of scientific consensus that we humans are doing this to ourselves, this shouldn’t come as a surprise.

Back in 2011, Starbucks’ head of sustainability Jim Hanna called increasingly extreme weather linked to climate change a “potentially significant risk to our supply chain.” But Brazil’s government—much like ours here in the United States—seems to have its head stuck in the sand on what to do about it.

NPR’s Weekend Edition has a fascinating look at the long-term implications of Brazil’s drought and dips a toe into the local politics:

What one farmer feels far into the Brazilian countryside is pretty much exactly what scientists in Brazil’s cities are saying, too.

Hilton Silveira Pinto is an agro-climatologist who has worked on a number of studies for EMBRAPA, Brazil’s government agency for agriculture.

“The regions where we plant coffee today, especially the ones on lower elevations, will be getting hotter,” he says. “And many of the coffee plantations in these areas will probably have to be abandoned.”

Since coffee is grown on carefully cultivated trees, it takes years for a plantation to reach maturity. As ideal coffee growing regions shift higher in elevation in a warming climate, existing plantations will force abandonment. NPR notes that some estimates project up to 10 percent of Brazil’s currently most productive coffee-growing regions will be fallowed in just the next few years.

The part of Brazil being hit hardest is in its highly populated southeastern corner, well south of the Amazon rainforest. In Brazil, climate models have mixed results when projecting future rainfall patterns (wetter for the southeast, but drier over the Amazon and the northeast), but are unambiguous about the fact that temperatures will continue to climb. This is a problem that is not going to go away.

And it’s not just coffee that’s being affected in the current drought. Brazil is also the world’s largest exporter of sugar, oranges, soy, and cattle. Prices for those commodities are also surging in response to the drought in South America. Some cities in Brazil have already begun water rationing. This week, Reuters reported that Brazil may have to lower its 2014 economic growth forecast as a result of the ongoing drought.

Looking ahead for the remainder of the Brazilian summer rainy season and into the autumn (March through May), the atmospheric odds seem to be stacked against any kind of significant rebound in rainfall any time soon. In fact, it seems increased dryness is the most likely scenario.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today.
