Modern global warming is the result of an increase in magnitude of the so-called greenhouse effect, a warming of Earth’s surface and lower atmosphere caused by the presence of water vapour, carbon dioxide, methane, nitrous oxides, and other greenhouse gases.
Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.
What is global warming? Global warming causes, effects, extreme weather, facts, and relation to climate change. Everything you wanted to know about our changing climate but...
Global warming is the long-term heating of Earth’s surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere.
What is global warming, explained. The planet is heating up—and fast. Glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace. It...
One of the most concerning impacts of global warming is the effect warmer temperatures will have on Earth's polar regions and mountain glaciers. The Arctic is warming...
Global warming refers to Earth’s rising average temperature, while climate change refers to changes in weather patterns and growing seasons around the world. Global warming causes climate change, which poses a serious threat to life on Earth.
The world is now warming faster than at any point in recorded history. Warmer temperatures over time are changing weather patterns and disrupting the usual balance of nature.
Scientists attribute the global warming trend observed since the mid-20 th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space.
