The importance of Climate change

First of all we should know why climate change is so important? specially for the Southern part of earth and over populated countries of earth.
The global climate is changing and it is likely to change further over coming decades due to increasing concentrations of 'greenhouse gases' in the earth's atmosphere caused largely by human activities.
This is the resulting in greater variations in weather patterns, a greater frequency of extreme weather events such as floods, droughts and tropical storms, and gradual rises in average temperatures and sea-level.



The southern part of earth is extremely vulnerable to climate change impacts because of its geographical location, historically disaster prone, high population density, high levels of poverty and the reliance of many livelihoods on climate-sensitive sectors, particular rural agriculture and fisheries.

The consequence of the climate change and variability are having two long-term impacts, one is through increased and intensified extreme events with potential to damage infrastructure, life and livelihoods and on the other hand are impacting all spheres of natural productivity through slow onset of degradation because of erratic behavior of precipitation and temperature regime, salinity, dryness etc.
