increase in the Earth's temperature caused by human activities that release greenhouse gases into the atmosphere. It has many consequences, including:
Rising sea levels: Low-lying cities, islands, and fresh water marshlands are being inundated by seawater.
Extreme weather: Climate patterns are changing, leading to droughts, fires, and flooding in different areas.
Melting ice caps and glaciers: This threatens polar bears and other animals, and reduces their feeding season.
Loss of animal habitats: Animal populations are declining as their habitats are lost.
Negative impact on human health: Global warming can have a negative impact on human health.
Negative impact on agriculture: Global warming can negatively impact agriculture.
Some human activities that contribute to global warming include:
Burning fossil fuels
Deforestation
Using hot water
Using ordinary light bulbs
Leaving electronic devices unattended
