  2. Causes of climate change - Wikipedia

    en.wikipedia.org/wiki/Causes_of_climate_change

    While aerosols typically limit global warming by reflecting sunlight, black carbon in soot that falls on snow or ice can contribute to global warming. Not only does this increase the absorption of sunlight, it also increases melting and sea-level rise. [58] Limiting new black carbon deposits in the Arctic could reduce global warming by 0.2 °C ...

    Scientific consensus on causation: Academic studies of scientific agreement on human-caused global warming among climate experts (2010–2015) reflect that the level of consensus correlates with expertise in climate science. [435] A 2019 study found scientific consensus to be at 100%, [436] and a 2021 study concluded that consensus exceeded 99% ...

  4. Overexploitation - Wikipedia

    en.wikipedia.org/wiki/Overexploitation

    Overexploitation, also called overharvesting or ecological overshoot, refers to harvesting a renewable resource to the point of diminishing returns. [2] Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish.

    In a 2021 guest post titled, "Overshoot: Where We Now Stand," Michael Dowd wrote that Catton's book is "the single most important book I have ever read." [24] He also quotes Richard Heinberg saying, "Climate change is not our biggest problem; overshoot is. Global warming is but a symptom of ecological overshoot."

    On a scale of 1 out of 7, where higher numbers indicated greater disagreement, "global warming is already underway" had a mean rating of 3.4, and "global warming will occur in the future" had an even greater agreement of 2.6 Surveyed scientists had less confidence in the accuracy of contemporary climate models, rating their ability to make ...

    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 ...

  9. Greenhouse gas - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas

    Global warming potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere over a specific time period, relative to carbon dioxide (CO 2). [37]: 2232 It is expressed as a multiple of warming caused by the same mass of carbon dioxide (CO 2). Therefore, by definition CO 2 has a GWP of 1.
