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 .
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. [74] 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 ...
Climatic changes due to internal variability sometimes occur in cycles or oscillations. For other types of natural climatic change, we cannot predict when it happens; the change is called random or stochastic. [12] From a climate perspective, the weather can be considered random. [13]
Environmental degradation is the deterioration of the environment through depletion of resources such as quality of air, water and soil; the destruction of ecosystems; habitat destruction; the extinction of wildlife; and pollution. It is defined as any change or disturbance to the environment perceived to be deleterious or undesirable.
While water vapour and clouds are the biggest contributors to the greenhouse effect, they primarily change as a function of temperature. Therefore, they are considered to be feedbacks that change climate sensitivity. On the other hand, gases such as CO 2, tropospheric ozone, [21] CFCs and nitrous oxide are added or removed independently from ...
By ANDREW TAVANI Signs of the changing seasons are everywhere right now: the ever decreasing daylight; the preemptive Christmas commercials on TV; and, of course, the most ubiquitous and pleasant ...
acclimation - the process of an organism adjusting to chronic change in its environment. acid mine drainage - the outflow of acidic water from metal mines or coal mines. acid rain - rain or other forms of precipitation that is unusually acidic. adaptation - a characteristic of an organism that has been favoured by natural selection.
