For years, humankind has been warned of the dangers of global warming. We are now feeling the effects of climate change on an unprecendented scale, with habitats and ecosystems around the world being affected. But the question remains: How did global warming happen and what implications does it have?
Climate scientists agree that global warming, also known as the “greenhouse effect,” is tied to the burning of fossil fuels, such as coal and oil, as well as deforestation and land-use changes. Carbon dioxide, chlorofluorocarbons (CFCs) and other industrial pollutants released into the atmosphere trap more heat and raise the temperature of the planet. According to the United States Environmental Protection Agency, levels of carbon dioxide in the atmosphere are currently at the highest concentrations ever recorded.
Another factor that scientists point to for the increased levels of carbon dioxide is the increased population of humans. More people naturally use more energy, contributing to the burning of more fossil fuels. Also, the heightened number of livestock and agricultural processes, including the burning of fuels to clear vegetation and the use of oil-based agrochemicals, are all contributing to global warming.
The large-scale effects of global warming continue to be felt all over the world. From increased drought, to sea-level rise, to more intense hurricanes and storms – disasters are becoming more frequent, more intense and more costly. In the United States alone, more than $500 billion of damaged property, medical costs and lost wages has been attributed to the effects of global warming.
It is clear that the consequences of global warming threaten us all. Scientists and policy makers have encouraged individuals and businesses to make some changes in order to reduce their carbon footprint. These include consuming fewer resources, conserving energy, eating less meat, and reducing the use of plastics. Collectively, these actions can help to reduce the amount of carbon dioxide released into the atmosphere.
Global warming is a complex issue, and its implications range from environmental and economic to social and political. Fortunately, progress is being made on both a global and local scale. Governments are increasingly presented with strategies to reduce their carbon-related emissions, and the drive towards renewable energy is gaining momentum. Although much work remains to achieve a sustainable future – there is cause to be optimistic.
We may not be able to turn back the clock on global warming, but we can take steps to reduce its impact on our planet and humanity. Start small by implementing simple changes like using canvas bags instead of plastic, transitioning to renewable energy, choosing electric vehicles and eating more plant-based foods. Our collective efforts have the potential to reverse the course of global warming and avert disaster. Let’s work together to make the world a better place for future generations.
