The Effects of Global Warming
Global warming, the current state of climate change, has a wide range of effects on the world. These effects range from population-threatening effects such as how much food a village in Africa produces over the next few decades, to nuisances, such as how you feel during the springtime. Overall, most of the implications of global warming, be they long-term or short-term, are negative.
Hungry, Hungry Humans
Common sense would lead us to believe that global warming could probably help the world feed itself. After all, in colder climates, food production is not easy. But the facts show that global warming will actually hurt food production. For example, in low-latitude, dry climates, even a slight increase in temperature can decrease the amount of food a crop yields. This will affect places such as Africa and Asia, two of the world’s regions that are more likely to suffer from starvation. But even in other areas, global warming will decrease crop yields after the temperature increases by more than 3 degrees Celsius, according to the Physicians for Social Responsibility. This can have a negative impact on worldwide food production, raising food prices and increasing starvation across the globe.
Heat and Health
Global warming isn’t always slow and steady. Along with an overall increase in global climate come spontaneous heat-waves, which can bring health problems. Fainting, heatstroke and heat exhaustion are among the health risks associated with global warming. But the heat is not the only problem. According to the Physicians for Social Responsibility, global warming also spawns new infectious diseases and the resurgence of diseases common in the past, such as malaria and cholera. Overall, global warming’s impact on human health is not just in its heat but also in what that heat can produce.
Fewer Familiar Faunae
While humans have the ability to adapt to many of the world’s changes, including global warming, animals are not so lucky. As the temperature rises across the globe, the habitats housing diverse species of animals change. A change in habitat forces the animals to adapt, migrate or die. Because animals are all interconnected in the food chain, the loss of one animal could mean the loss of others, which could spiral out of control for a long time.
More Sneezing and Wheezing
Global warming is linked to an increase in carbon dioxide in the air. Because plants rely on carbon dioxide to grow and produce pollen, an increase in the air’s carbon dioxide can lead to more problems for people with allergies. According to the Natural Resources Defense Council, 20 to 30 percent of the population suffer from allergies. Global warming could worsen the effects of allergies, causing more people to miss work, miss school and just feel bad.
Experts agree that the short-term effects of global warming can be rather easily alleviated. The main question is whether the human race will put enough effort into tackling the long-term effects.
