What is global warming in one paragraph?

Answer 1

The earth has always been kept comfortably warm by the greenhouse effect. This is supported by the earth's carbon and water cycles that move carbon dioxide and water vapor (both greenhouse gases) in and out of the atmosphere. Burning the fossil fuels, coal and oil, for industry, transport and for generating electricity releases extra carbon dioxide that had been hidden away for millions of years. Trees and forests are one excellent way of absorbing carbon dioxide from the atmosphere, but unfortunately deforestation is still happening in just about every country in the world. So all these extra greenhouse gas emissions are causing an enhanced greenhouse effect, keeping more and more of the sun's heat in the atmosphere, and causing what we now call global warming.

Answer 2

Global warming refers to the long-term increase in Earth's average surface temperature, primarily driven by human activities that release greenhouse gases into the atmosphere. These gases trap heat and result in climate change, leading to rising sea levels, extreme weather events, and disruptions to ecosystems and agriculture. Urgent action is needed to mitigate the impacts of global warming and transition to more sustainable practices to protect the planet for future generations.
