Global warming is the long-term rise in the average temperature of the Earth’s climate system. It is a major aspect of current climate change, and has been demonstrated by direct temperature measurements and by measurements of various effects of the warming.

Global warming is the gradual increase of the Earth’s average surface temperature. The main component of global warming is the increased emission of greenhouse gases.

The greenhouse effect and human activity are the two main causes of global warming.

1. To stop global warming, we need to stop emitting greenhouse gases into the atmosphere.
2. We can do this by using less fossil fuels, planting trees, and protecting our forests.

The effects of global warming are melting glaciers, sea level rise, and more extreme weather events.

The term “global warming” was first used in its modern sense on August 6, 1975, by Wallace Smith Broecker in the title of a scientific paper in the journal Science.

Global warming is bad because it is causing the Earth’s atmosphere to warm, which is causing the Earth’s climate to change.

Climate change started long ago when the Earth began to warm and cool. It continues today as the Earth warms and cools.

We can stop climate change by reducing our reliance on fossil fuels and by investing in renewable energy sources.

The Intergovernmental Panel on Climate Change (IPCC) says that climate change will be irreversible if we exceed 1.5°C of global warming.
