In the last century, global temperatures have risen considerably and this phenomenon has been credited to human activities, with the most significant factors being the burning of fossil fuels, emissions from industry and land-use changes. The fact is that there is overwhelming evidence for the effects of global warming, and these effects can all be attributed to human activities.
One of the most immediate and visible effects of global warming is the effect on the global climate, which is characterized by an increase in temperatures. This, in turn, leads to an increase in the frequency and intensity of extreme weather events. These events, such as floods and droughts, have cost people billions of dollars and put immense pressure on governments to mitigate the effects.
Global warming has also caused an increase in the sea level due to melting glaciers. This is because, as ice melts, the ice turns to liquid, which expands in size as it warms up. The steepest rate of sea-level rise was recorded in the latter half of the 20th century, and the problem is likely to become even direr in the near future.
Another serious effect of global warming is the changes it has caused in the ocean’s ecosystem. The ocean absorbs around 30 percent of the extra heat generated from human activities, and has become significantly warmer as a result. Warmer ocean temperatures have caused disruption in ocean currents, as well as a significant reduction in the amount of oxygen in the ocean, leading to drastic changes in biodiversity.
It is clear that the effects of global warming are far-reaching and potentially destructive. It is therefore essential that we take action to mitigate the effects. There have been several efforts, such as the Paris Agreement, by which signatory states have committed to reduce their emissions of greenhouse gases and limit their contribution to global warming.
Additionally, efforts have been made to promote clean energy sources such as wind and solar power, in order to reduce the reliance on fossil fuels. Finally, on a personal level, each one of us has the power to limit our contribution to global warming. This can be done by reducing our energy consumption, reducing food waste and investing in renewable energy sources.
It is high time that we address the very real threat of global warming and take action to reduce its devastating effects in the short and long term. It is only with our collective efforts that we can ensure a livable world for ourselves and for our future generations.
