What is global warming and why should we be worried
According to the United States Geological Society (USGS), “Global warming” “refers to the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere.”
On the other hand, greenhouse gas (GHG) is a gas that enables heat to be trapped by hindering the movement of longwave radiation out of the atmosphere of Earth. What it does is cause the concentration of atmospheric carbon dioxide (CO2) to increase staggeringly. Because of this, global warming is happening.
Owing to all of this, the US-based Natural Resources Defense Council (NRDC) has stated that the world has seen its warmest five years between 2015 and 2021 since 1880! If that happens, the temperatures on most of the Earth’s surface will reach a tipping point – a point of no return for the existence of humans on the planet.
What role do humans play in all of this? To a large extent, human activities cause the concentration of GHGs to swell. In other words, humans are directly responsible for global warming as we burn fossil fuels (coal and oil) at a tremendous rate. Additionally, pollution caused by industries and power-guzzling vehicles is also another major contributor to GHGs, thus, in turn, global warming.
GHG causes temperatures on our planet to be hotter than ever, storms to be more devastating than the ones that wreaked this planet since recorded history, and ceaselessly increasing droughts in the less fortunate parts of Earth.
