Environmental change is a change or disturbance of the environment most often caused by human influences and natural ecological processes. Environmental changes include various factors, such as natural disasters ,of human interferences, or animal interaction .
Global change in broad sense refers to planetary-scale changes in the Earth system. It is most commonly used to encompass the variety of changes connected to the rapid increase in human activities which started around mid-20th century, i.e., the Great Acceleration.
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 ...
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable. [75] As indicated by the I=PAT equation, environmental impact (I) or degradation is caused by the combination of an already very large and increasing human population (P), continually increasing economic growth or per capita affluence (A ...
Thermal pollution, sometimes called "thermal enrichment", is the degradation of water quality by any process that changes ambient water temperature.Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence.
One of the most important ways animals can deal with climatic change is migration to warmer or colder regions. [110] On a longer timescale, evolution makes ecosystems including animals better adapted to a new climate. [111] Rapid or large climate change can cause mass extinctions when creatures are stretched too far to be able to adapt. [112]
Climate change contributes to disaster risk. So experts sometimes see climate change adaptation as one of many processes within disaster risk reduction. [17] In turn, disaster risk reduction is part of the broader consideration of sustainable development. Climate change adaptation and disaster risk reduction have similar goals (to reduce ...
