Those main conclusions are that climate is changing in ways unusual against the backdrop of natural variability; that human activities are responsible for most of this unusual change; that significant harm to human well - being is already occurring as a result; and that far larger --- perhaps catastrophic — damages will ensue if serious remedial action is not started soon.

«Climate Change» refers to the general subject matter of changes in global or regional climates that persist overtime, whether due to natural variability or as a result of human activity.»

«In considering the question of human activity and climate change it is essential to distinguish between global warming, which is a progressive increase in the annual mean global temperature, and human - activity - induced greenhouse warming, as may, for example, be caused by the release of greenhouse gases into the atmosphere as a result of fossil fuel combustion or deforestation.»

The term is used in the context of global climate change to refer to gaseous emissions that are the result of human activities, as well as other potentially climate - altering activities, such as deforestation.

«Climate Change» is a general term used when referring to a wide range of effects brought about by human activities such as burning fossil fuels, deforestation, and «heat island effects» resulting from buildings and pavement in the major human settlements.

Any change in climate over time, whether due to natural variability or as a result of human activity.

Indeed, strong observational evidence and results from modeling studies indicate that, at least over the last 50 years, human activities are a major contributor to climate change.Direct human impact is through changes in the concentration of certain trace gases such as carbon dioxide, chlorofluorocarbons, methane, nitrous oxide, ozone, and water vapor, known collectively as greenhouse gases.

Despite its scale, the Amazon is also one of the fastest changing ecosystems, largely as a result of human activities, including deforestation, forest fires, and, increasingly, climate change.

«Climate change in IPCC usage refers to any change in climate over time, whether due to natural variability or as a result of human activity.

It presents conclusions, proposes lines of possible action (including suggestions as to the factors which might form the basis for negotiations) and outlines further work which is required for a more complete understanding of the problems of climate change resulting from human activities.

The term sometimes is used to refer specifically to climate change caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes.

However, long - term climate change over many decades will depend mainly on the total amount of CO2 and other greenhouse gases emitted as a result of human activities.

Causes of climate change Modern day climate change is attributed to a number of factors, but one stands out above all others: increased greenhouse gasses as a result of human activity.

A wide range of human activities affect marine biodiversity both in direct ways, such as exploitation by fisheries, habitat loss due to dredging, filling, and other construction influences, fishing gear impacts, and pollution, and in less direct ways, including effects of global change resulting in acidification, warmer waters, and coastal inundation.

Managing this threat is particularly challenging because it does not arise from local human actions, but from global changes to the atmosphere as a result of human activities.

Perhaps the most important issue in all this is, as the Royal Society pointed out in their assessment of geoengineering, the first and foremost thing we have to do to stop climate change is radically limit greenhouse gas emissions resulting from human activity — stopping burning fossil fuels and stopping deforestation are at the top of list for how to do that.

Because human activities, such as the emission of greenhouse gases or land - use change, do result in external forcing, it is believed that the large - scale aspects of human - induced climate change are also partly predictable.
