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% ...
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 ...

Climate solutions provide hope that global warming can be curbed. The world has lost decades in mobilizing against climate change, because of denialism, misinformation and inertia, among other ...
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.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
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.
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 ...
