Global warming is causing the price of food to increase all over the globe because of severe weather changes. Over the last few decades, the world we know has had drastic changes. The price of food has been affecting us all globally, and now scientists believe they know why. Global warming was thought to be a myth, or a hoax to scare people all around the world. Now scientists have found out that farmers are forced to charge more because the cost to grow food is increasing every year. This is because severe climate change has caused hotter days, colder nights and less rainfall. These factors are important to farmers because growing products such as wheat, corn, maize and rice rely heavily on the climate. In the end it affects everybody in the supply-chain, if the cost to manufacture these goods continues to rise, the price that we pay to purchase these products will also inflate. This essay will detail how global warming is affecting us all, and how we can all do our part to make a difference. The primary source of information will be articles written by climate change experts such as James Edward Hansen, Margaret Hilda Thatcher David Suzuki and some other recognized authors from newspaper articles.
Global Warming is the increase of the Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. The Earth's climate is mostly influenced by the first 6 miles or so of the atmosphere which contains most of the matter making up the atmosphere. This is a very thin layer if you think about it, but yet nobody is doing anything to control the amount of greenhouse gases we are spewing into the atmosphere. We have released so much carbon dioxide and other greenhouse gases that our planet's atmosphere is now like a thick, heat-trapping blanket. “By disrupting the atmospheric balance that keeps the climate stable, we are now seeing extreme effects around the globe. It's like a thermostat that's gone haywire — it just doesn't work the way it should. The result is that the climate changes are more severe, and it gets warmer in all parts of the globe. Extreme weather events also become more common”. (Suzuki)
Scientists at Stanford University said warmer temperatures and changes in rainfall patterns have pushed up the cost of wheat, maize, rice and soya by 5 per cent since the 1980s.This weather is causing the farmers that grow these products more money to produce them, because they end up watering the crops themselves. This is very important because farmers are now forced to raise the price for their products, causing a domino effect in the supply chain. The drop in the productivity of crop plants around the world was not only caused by changes in rainfall but was also because higher temperatures can cause dehydration, prevent pollination and lead to slowed photosynthesis making it much more expensive to maintain. “Wheat production in Russia showed the biggest drop, with yields 15 percent lower than what they could've been. This is tens of billions of dollars a year in lost productivity because of Global warming”. (Lobell)
Since 2008 the world average prices have risen by 217 percent for rice, 136 percent for wheat, 125 percent for corn, and 107 percent for soybeans. “Scientists predict that corn prices, adjusted for inflation, will rise by 42 to 131 percent by 2050. Climate change is expected to diminish rice yields, lifting prices from 11 to 78 percent and wheat prices may rise from 17 to 67 percent” (The Guardian) Wheat, rice, corn and soybeans account for the majority of calories consumed by the human race, either directly or as meat from animals raised on grains. One-quarter of all the maize and other grain crops grown in the US now ends up as biofuel in cars rather than being used to feed people. New analysis...
