The Earth’s climate is a complex system, greatly affected by human activity. As such, it can be difficult to pinpoint the exact time global warming began. However, researchers agree it has been rising steadily over the past few centuries, particularly since the industrial revolution, when human activities began to have a more direct impact on the Earth’s climate.
It is clear that global climate change has become an issue of great concern. NASA’s Earth Observatory has collected data that shows how the global average temperature is rising. According to their data, the Earth’s global average temperature has risen by an average of 0.8 degrees Celsius since 1880. Meanwhile, the American Meteorological Society (AMS) reports that since the 20th century, several global warming trends have been observed worldwide.
Although evidence suggests anthropogenic activities are influencing global warming, studies have proven this is not the only cause. Natural climate phenomena like the El Niño-Southern Oscillation (ENSO) have been attributed to both cooling and warming spells, significantly affecting the Earth’s climate. Similarly, increased levels of solar radiation have been found to have an impact on global climate change.
In addition to global warming, researchers have found that the Earth’s climate has been increasing in variability, leading to record-breaking extreme weather events. This is also largely attributed to human activities, as the pollution being released into the atmosphere is causing the Earth’s atmosphere to heat up more rapidly.
While the cause of global warming is still highly debated, one thing is clear – the impacts of global warming are becoming increasingly evident. In recent years, the planet has experienced more extreme weather events, such as more frequent heat waves, floods and droughts, as well as rising sea levels, which are leading to the displacement of people and immense biodiversity loss.
Given the significance and magnitude of this issue, it is clear that urgent action is needed in order to slow down and eventually halt global warming. This can be achieved through the implementation of sustainable economic practices and an increased reliance on renewable energy sources. There is a need to shift away from the status quo and towards alternative, more sustainable solutions.
It is obvious that climate change is a very real and pressing issue – and one that will impact us all for generations to come. If we do not act quickly and decisively, the consequences of global warming will continue to threaten not only our environment, but also human health and livelihoods. In order to combat this, it is essential that we understand when global warming began and the causes of global climate change, as this information is key to setting up effective and sustainable solutions.
