Question

Which definition best describes global warming?

a long-term change in the Earth's climate
a long-term increase in the Earth's average temperatur
a long-term change in the climate of a region or a city
Osolar heat that is radiated out into space

Answer 1

Global warming is a long-term change in the Earth's climate caused by greenhouse gases. It leads to rising temperatures, melting ice caps, and other impacts. Actions to reduce emissions and promote sustainability are crucial.

Step-by-step explanation:

Global warming is a long-term change in the Earth's climate caused by the increase of greenhouse gases in the atmosphere, primarily from human activities. This leads to a rise in the Earth's average temperature, resulting in various impacts such as melting ice caps, rising sea levels, and more frequent extreme weather events.

For instance, the burning of fossil fuels releases carbon dioxide into the atmosphere, trapping heat and causing the planet to warm. Deforestation also contributes to global warming as trees absorb carbon dioxide and release oxygen. Additionally, industrial processes and agriculture produce other greenhouse gases like methane and nitrous oxide.

It is important to address global warming through actions like reducing carbon emissions, transitioning to renewable energy sources, and promoting sustainable practices to mitigate its impacts and protect the planet for future generations.
