Deforestation is defined as the conversion of forest to other land uses (regardless of whether it is human-induced). [14] Deforestation and forest area net change are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a given period. Net change, therefore, can be positive or ...
The direction and magnitude of the effects of ocean acidification, warming and deoxygenation on the ocean has been quantified by meta-analyses, [136] [142] [143] and has been further tested by mesocosm studies. The mesocosm studies simulated the interaction of these stressors and found a catastrophic effect on the marine food web, namely, that ...
In addition, climate change impacts oceanic currents and sea levels, further altering fish distributions and habitats. Furthermore, ocean acidification, resulting from increased CO2 levels, compromises the ability of shellfish and corals to form shells and skeletons, further endangering marine ecosystems and the communities that depend on them.

[10] [11] The relationship between deforestation and climate change is one of a positive (amplifying) climate feedback. [12] The more trees that are removed equals larger effects of climate change which, in turn, results in the loss of more trees. [13] Forests cover 31% of the land area on Earth.
The environmental impact of irrigation includes the changes in quantity and quality of soil and water as a result of irrigation and the ensuing effects on natural and social conditions at the tail-end and downstream of the irrigation scheme. The impacts stem from the changed hydrological conditions owing to the installation and operation of the ...
Traditionally the people of the Valparaíso Province found their living through artisanal fishing and agriculture. In the past several decades the region's main economy is tourism, in 2016 there was an estimated 1.498,295 tourists visiting the area. [14] The largest ports in the country are located in the Valparaiso region.
More people will be exposed to the ravages of flooding and drought. But if the nations involved in the Paris talks stay on their current emissions track and don’t reduce greenhouse gas emissions, temperatures could go up by almost 6 degrees Celsius this century, according to the Committee on Climate Change, an independent body that advises ...
Blue carbon is defined by the IPCC as "Biologically driven carbon fluxes and storage in marine systems that are amenable to management." [2]: 2220 Another definition states: "Blue carbon refers to organic carbon that is captured and stored by the oceans and coastal ecosystems, particularly by vegetated coastal ecosystems: seagrass meadows, tidal marshes, and mangrove forests."
