An Inconvenient Truth: a film that showcases Al Gore's presentation on global warming, arguing that humans are the cause of climate change. The 11th Hour: a 2007 documentary film, created, produced and narrated by Leonardo DiCaprio, on the state of the natural environment.
The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the ...
The Earth radiates it as heat, and greenhouse gases absorb a portion of it. This absorption slows the rate at which heat escapes into space, trapping heat near the Earth's surface and warming it over time. [20] While water vapour and clouds are the biggest contributors to the greenhouse effect, they primarily change as a function of temperature.
The Fourth National Climate Assessment ("NCA4", USGCRP, 2017) includes charts illustrating that neither solar nor volcanic activity can explain the observed warming. (from Causes of climate change ) Image 51 Warming influence of atmospheric greenhouse gases has nearly doubled since 1979, with carbon dioxide and methane being the dominant drivers.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
The rate Earth is warming hit an all-time high in 2023 with 92% of last year's surprising record-shattering heat caused by humans, top scientists calculated. The group of 57 scientists from around ...
In the 1980s, the terms global warming and climate change became more common, often being used interchangeably. [29] [30] [31] Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system, such as precipitation changes.
