Soaring coffee prices

February 20, 2025 By EarthWise Leave a Comment

Coffee prices are soaring again

Wholesale coffee prices hit record highs in the midst of the Trump administration’s deportation and tariff dispute with Colombia.  But coffee prices have already been trading near 50-year highs for a while as a result of shortages related to extreme weather and increased global demand.

In recent years, repeated droughts and flooding have put pressure on the global supply of coffee.  These climate swings have caused prices to soar, much as they have for other staples like cocoa, olive oil, and orange juice.  All the while, the global demand for coffee has kept rising.

Coffee is one of the world’s most consumed beverages, but it can be grown only under very specific conditions, namely in misty, humid, and tropical climates, and in rich soil free of disease.   The United States imports nearly all of its coffee – there is only a small amount grown in Hawaii.  Otherwise, the US is the world’s largest coffee importer.  With a limited number of sources for the beans, global coffee prices are very susceptible to the effects of extreme weather.

More than half of the world’s coffee production comes from arabica beans, and Brazil is the largest exporter.  A severe drought there this summer devastated the harvest that typically runs from May to September.   In Vietnam, a severe drought followed by heavy rains harmed the world’s largest source of robusta, the second most popular coffee variety.

People tend to think of coffee as a commodity and not so much as an agricultural product, subject to the vagaries of weather and having prices that fluctuate accordingly.  The bottom line is that drinking coffee is likely to become a bigger strain on one’s own bottom line.

An Arctic Bus | Earth Wise

Developing a bus capable of navigating in the Arctic

People have built vehicles for all sorts of extreme environments.  There are deep-sea exploration vessels and there have been lunar and Mars rovers.  But one thing that hasn’t existed so far are buses to transport groups of people around in extreme conditions in the Arctic.  Engineers at two Russian Universities are developing a passenger bus for riding in the Far North.   The project is being funded by the Russian Federation Ministry of Science and Higher Education and the URAL Automobile Manufacturing Plant.

The requirements for the vehicle are daunting.  The bus must be operable at extreme temperatures – 60 below zero Fahrenheit and lower – and have no difficulties even in challenging off-road conditions.

Current Arctic crew buses are not capable of getting through snow blockages and the all-terrain tracked vehicles that can get through them do not have sufficient passenger capacity. In addition to being able to go through snowbanks, the bus should be able to float on water for an hour.

Apart from its ability to withstand harsh Arctic conditions, the bus will also have a quarters module.  This means that it will have an autonomous life-support system for passengers in case of emergency.  The quarters module will be designed to sustain up to 20 people for up to 24 hours.  The module might also be used to hold medical equipment, thereby enabling practitioners to reach remote settlements and treat patients. 

The first tests of prototypes for the bus will be conducted in the near future.  The project aims to have the new Arctic Bus design complete and ready for manufacture by the end of 2023 and it will go into production in 2024.

Researchers at Yale are using some advanced technology to analyze air samples in order to obtain a detailed look at the molecular makeup of organic aerosols, which have a significant presence in the atmosphere.
