As our world continues to be shaken by the effects of a changing climate, the question of whether global warming is a major problem becomes an increasingly important one. Scientists have determined that the increase in global temperatures over the past few decades, which is more than double the rate of the previous century, are largely attributed to human activities, such as the burning of fossil fuels and the destruction of forests. With an array of potentially destructive repercussions, including rising sea levels, devastating natural disasters, and a host of public health and environmental issues, it is clear that global warming is indeed a very real problem.
Though some may deny it or downplay its effects, the reality is sobering. In 2019, the Intergovernmental Panel on Climate Change stated that two-thirds of the negative impacts of warming temperatures will be felt in the most vulnerable countries and regions, many of which are already dealing with poverty, limited access to fresh water and infrastructure, or political instability. In addition to an expected rise in sea levels, changes in oceanic circulation patterns, and unpredictable weather patterns, global warming has already been linked to higher rates of heat-related illness, drought and increased spread of infectious diseases.
The effects of global warming are not only apparent on a national scale, however. Many communities across the world have already begun to suffer due to severe droughts and floods, rising seas, and other climate-related events. For example, in vulnerable areas such as the Sahel region of Africa, which is already struggling with desertification, prolonged heat waves and erratic rainfall have compromised food security and put additional stress on its populations. Reports from the Intergovernmental Panel on Climate Change similarly point to increased difficulty in farming and livestock production due to climate change, and predict more severe flooding and more frequent tropical storms.
The world is speeding ever closer to the point of no return on global warming, and it is in our best interests to act quickly and effectively. Government regulations on greenhouse gases and incentivizing eco-friendly investments are a start, but much of the solutions lies in our hands. Individuals need to be conscious of what they can do to help mitigate climate change: driving less, eating less meat, investing in renewable energy, conserving water and electricity, and generally reducing the environmental impact of our everyday habits.
Global warming is a major problem, and one that must be addressed immediately. To bring about meaningful change and ensure that our world has a safe and prosperous future, governments must work with citizens, businesses and organizations to enable a shift towards a green economy and lifestyle. It is up to us to take action and make the necessary changes, or risk the potentially catastrophic consequences of global warming.
