Surface Temperature Increase
In 2013, the American Journal of Climate Change published a piece written by scholars at the Federal University of Rio De Jeneiro that highlights the potential scenarios for the climate in the region. One of the major changes projected is an increase in air temperature by 2100. Brazil's average temperature is expected to increase between 2 and 5 degrees celsius, and, due to the warming trend, the weather extremes will be more frequent. Colder cold days and warmer warm days are expected, but it is projected that 40% to 70% of the days and 55% to 85% of the nights will be hot. Though the cold days will be colder, there will be a lot less of them.
Precipitation Changes
In addition to the surface temperatures increasing, Brazil is expected to experience an increase in both the intensity and the frequency of rainfall. The area is expected to experience much heavier storms due to the warming, storms that are projected until the end of the 21st Century. In addition, Brazil is expected to have longer dry periods and shorter wet seasons, also an affect of the warming. Though increased rainfall and dry seasons is the overall trend for the country, the damage will be different based on the region. In the south and south-east regions, rainfall patterns are expected to increase by up to 30 percent. In the north and north-east regions, however, rainfall could decrease by up to 40 percent. Both scenarios will hurt agriculture. Too much rainfall can wash away crops and cause flooding, while not enough rainfall will make growing anything nearly impossible.
Concluding Statement
Brazil is incredibly unique- it is the fifth largest country in the world, with a coast stretching almost 2,700 miles. Within this country are plateaus, mountains, savannas, and wetlands. Perhaps the most notable geographical feature- the Amazon River and Rain Forest. Even though this country holds incredible beauty, and many are using cleaner energy, if the warming trend does not change, this place is in trouble. Because of the importance of the Amazon Rain Forest, both Brazil and surrounding areas will be negatively affected if the country does not make a larger effort to use clean energy and educate everyone about the dangers of climate change. Because the Amazon is so large, it exchanges a lot of water and energy with the atmosphere, which is thought to affect local and regional climates. The ecosystem of this rain forest is so important because of its size. A vast amount of oxygen is created within it through photosynthesis with all of the plant life. In addition, water released by plants into the atmosphere and to the ocean by the river, influences ocean currents. The deforestation of the Amazon is a nasty cycle- it releases incredible amounts of CO2 into the atmosphere, as well as decreases the amount of oxygen released into the atmosphere because of the destruction of trees. Brazil does not only need to use cleaner energy, but protect its rain forests. The temperature and precipitation projections for the country are frightening, and this paired with continued deforestation can affect not only the country, but the world climate. A country of this size must make a strong effort to reduce Greenhouse Gas emissions, use clean energy, and set an example for the rest of the world. The country is home to far too many beautiful features and people to allow itself to be destructed by climate change.
