WHAT IS GLOBAL WARMING?

GLOBAL WARMING



Emission of Green house gases in 2005.

Global warming is nothing but the increase in the average temperature of the earth due to emission of c02, green house gases....etc....According to the Intergovernmental Panel on Climate Change (IPCC), global surface temperature increased by 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 20th century. 

Save the Earth, Plant a Tree!

Most of the observed temperature increase since the middle of the 20th century has been caused by increasing concentrations of greenhouse gases, which result from human activities such as the burning of fossil fuel and deforestation. Which affect cloud properties and block sunlight from reaching the surface, has partially countered the effects of warming induced by greenhouse gases. An increase in global temperature will cause sea

levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. Warming is expected to be strongest in the Arctic and would be associated with continuing retreat of glaciers, permafrost and sea ice.Warming and related changes will vary from region to region around the globe, though the nature of these regional changes is uncertain. As a result of contemporary increases in atmospheric carbon dioxide, the oceans have become more acidic, a result that is predicted to continue. Proposed responses to global warming include mitigation to reduce emissions, adaptation to the effects of global warming, and geoengineering to remove greenhouse gases from the atmosphere.

(Reducing the amount of future climate change is called mitigation of climate change.)
