The science behind global warming is indisputable, and the debate is no longer if this phenomenon is occurring, but rather how to counter its effects. So what is the scientific definition of global warming? Simply put, global warming is the process of our planet’s average surface temperature increasing over time due to the greenhouse gas emissions created by humans.
The greenhouse effect that leads to global warming is an established scientific fact. In 1750, before the Industrial Revolution, the global average surface temperature was an estimated 59 degrees Fahrenheit, and over the past 250 years, a slow but steady rise in average surface temperatures has been recorded. On average, the global surface temperature is estimated to have risen 1.5 degrees Fahrenheit since the beginning of the Industrial Revolution, a contributing factor to the rise of sea levels and the melting of polar ice caps.
This temperature rise is linked to the amount of carbon dioxide and other greenhouse gases that are released into the atmosphere. These gases act as a barrier, trapping the sun’s heat in the terrestrial atmosphere, thus causing the Earth’s temperature to rise. This is a natural phenomenon and the reason why the Earth’s climate has remained fairly habitable and stable in spite of the solar system’s 350-degree temperature range.
The Earth has been able to compensate for the increased levels of carbon dioxide and other gases until the Industrial Revolution brought an unprecedented increase in the production of these gases. In addition to burning fuel and deforestation, the process of war and metal smithying in the 1700s produced a record amount of emissions that the planet could no longer absorb. Subsequently, further temperature rises have been recorded.
However, opinions remain divided over what effects this rise in temperature will have. While some experts have warned of adverse consequences, including more frequent and damaging hurricanes and droughts, others have noted that global warming could have potential benefits for certain regions of the world. For instance, some areas may be able to produce food more easily due to the rising temperatures.
Most importantly, scientists across the world agree that global warming is a reality and that decisive action must be taken in order to mitigate its effects. There are some simple, everyday steps that people can take to reduce their own contributions to climate change. These include switching to renewable energy sources such as solar power, conserving water, reducing emissions from cars, or avoiding products with large amounts of packaging. Furthermore, governments can work towards implementing regulations to control emissions, as well as subsidies to incentivize practices that reduce emissions.
At the same time, it is important to recognize that the effects of global warming cannot be completely reversed. Therefore, it is critical for governments to invest in infrastructure that can protect important geographical regions from the effects of climate change. For instance, coastal locations are particularly prone to the effects of sea level rise, and building seawalls can help to protect beaches and homes from flooding.
It is high time that policymakers, scientists, industry leaders, and citizens alike work together to address the global warming crisis. By understanding the scientific definition of global warming, the consequences of this phenomenon, and taking action locally and nationally, humanity can learn to counter the effects of climate change and preserve our planet for generations to come.
