Concept Explanation
 

Climate Change -Global Warming

 Global Warming: The term "global warming" is a specific example of climate change, which can also refer to global cooling. In common usage, the term refers to recent warming and implies a human influence. The United  Nations Framework Convention on Climate Change (UNFCCC) uses the term "climate change" for human-caused change, and "climate variability" for other changes. The Intergovernmental Panel on Climate Change (IPCC) concludes, "most of the observed increase in globally averaged temperature since the mid-twentieth century is very likely due to the observed increase in anthropogenic greenhous gas concentrations." Climate model projections summarised by the IPCC indicate that average global  surface temperature will likely rise a further 1.1°C to 6.4°C (2.0°F to 11.5°F) during the twenty-fint century. The range of values results from the use of differing scenarios of future greenhouse-gas emissione as well as models with differing climate sensitivity.

What is Global Warming:  Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. The global average air temperature near the Earth's surface increased o.74 + 0.18 °C (1.33 + 0.32 °F) during the hundred years ending in 2005. Although most studies focus on the period up to 2100, warming and sea level rise are expected to continue for more than a thousand years even if greenhouse gas levels are stabilised. The delay in reaching equilibrium is a result of the large heat capacity of the oceans. Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors.

Causes of Global Warming: The detailed causes of the recent warming remain an active field of research, but the scientific consensus is that the increase in atmospheric greenhouse gases due to human activity caused most of the warming observed since the start of the industrial era. Some other hypotheses departing from the consensus view have been suggested to explain the temperature increase. One such hypothesis proposes that warming may be the result of variations in solar activity.
