Climate change. Changes in surface air temperature over the past 50 years. [ 1] The Arctic has warmed the most, and temperatures on land have generally increased more than sea surface temperatures. Earth's average surface air temperature has increased almost 1.5 °C (about 2.5 °F) since the Industrial Revolution.
Main sources of global methane emissions (2008-2017) according to the Global Carbon Project [ 40] Methane emissions come from livestock, manure, rice cultivation, landfills, wastewater, and coal mining, as well as oil and gas extraction. [ 41] Nitrous oxide emissions largely come from the microbial decomposition of fertiliser.
Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes. [3] Global warming became the dominant popular term in 1988, but within scientific journals global warming refers to surface temperature increases while climate change includes global warming ...
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 warming trend, changes to precipitation patterns, and more extreme weather. As the climate changes it impacts the natural environment with effects such as more intense forest fires ...
Climate change vulnerability is a concept that describes how strongly people or ecosystems are likely to be affected by climate change. Its formal definition is the " propensity or predisposition to be adversely affected" by climate change. It can apply to humans and also to natural systems (or ecosystems).
Climate change adaptation is the process of adjusting to the effects of climate change. These can be both current or expected impacts. [1] Adaptation aims to moderate or avoid harm for people, and is usually done alongside climate change mitigation. It also aims to exploit opportunities.
Deforestation and climate change. Deforestation in the tropics – given as the annual average between 2010 and 2014 – was responsible for 2.6 billion tonnes of CO 2 per year. That was 6.5% of global CO 2 emissions. Deforestation is a primary contributor to climate change, [1] [2] and climate change affects the health of forests. [3]
Climate change mitigation (or decarbonisation) is action to limit the greenhouse gases in the atmosphere that cause climate change. Climate change mitigation actions include conserving energy and replacing fossil fuels with clean energy sources. Secondary mitigation strategies include changes to land use and removing carbon dioxide (CO 2) from ...
