Global Warming - NASA Science Global warming is the unusually rapid increase in Earth’s average surface temperature over the past century primarily due to the greenhouse gases released as people burn fossil fuels
Global warming | Definition, Causes, Effects, Solutions, Facts . . . 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
Climate change - Wikipedia Present-day climate change includes both global warming —the ongoing increase in global average temperature —and its wider effects on Earth's climate system Climate change in a broader sense also includes previous long-term changes to Earth's climate
Global Warming - National Geographic Society People often use the terms “global warming” and “climate change” interchangeably, but they are different Global warming refers to Earth’s rising average temperature, while climate change refers to changes in weather patterns and growing seasons around the world
What Is Global Warming? - National Geographic Climate change has accelerated the rate of ice loss across the continent The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere trap heat These gases let
What Is Global Warming? Definitions, Causes, and Effects Global warming is a gradual, long-term increase in the average temperature of Earth's atmosphere due to the greenhouse effect where gasses from various human activities, including the burning of fossil fuels, trap heat from solar radiation
Climate Change 101 - Cornell University Human actions, such as burning fossil fuels and deforestation, are rapidly driving global warming and changing the climate Global temperatures have increased significantly since pre-industrial times, leading to more extreme weather events, melting ice, and rising sea levels
What Is Climate Change? - NASA Science 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
