Definition of Global Warming:
Global warming is an unusually rapid increase in the Earth's average surface temperature over the past century, caused primarily by the release of excess (above normal) greenhouse gases. Greenhouse gases include carbon dioxide, methane, ozone, nitrous oxide, chlorofluorocarbons and water vapor. Water vapor that reacts with changes in temperature, and amplifies the effect of the initial warming forces. Fossil fuels - coal, oil and gas are by far the largest contributors to global climate change, producing greenhouse gas emissions that blanket the Earth and trap the Sun's heat inside the Earth.
Global warming is mainly caused by excessive emission of greenhouse gases. Global warming has been caused primarily by emissions of excess greenhouse gases over the past century, as the amount of greenhouse gases on Earth has progressively increased above normal levels. Means Global warming is mainly caused by the emission of more greenhouse gases. The most obvious causes of global warming are fossil fuels, urbanization, deforestation, and sophisticated human activities.
At present major Environmental issues:
At present major environmental issues is global warming responsible for changes in weather patterns such as too warmer summers, shorter winters and extreme weather. Fossil fuels, deforestation, landfills and fertilizers contribute to Climate Change. Global warming is an abnormally rapid increase in Earth's average surface temperature over the past century primarily due to more greenhouse gasses emitted.
What are Greenhouse Gases in simple words?
Greenhouse gases (also known as GHGs) are gases in Earth's atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. The main greenhouse gases are - Water vapor and Carbon dioxide.
What would happen if there were no Greenhouse Gases inside the Earth?
Without any greenhouse gases, Earth would be an icy wasteland. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space.
Greenhouse gases are part of Earth's atmosphere:
Actually Greenhouse gases are part of Earth's atmosphere. Generally the Earth is called the 'Goldilocks' Planet (not too hot, and not too cold) - its conditions are just right, not too hot or too cold, allowing life to thrive. Part of what makes Earth so amenable is its natural greenhouse gas effect. As a instance which maintains an average temperature of 15 °C.
A world without trees is a dead planet- We must rewind and replant for a better generation 🌎
