Pakistan and India that claimed thousands of lives this year . According to Skymet Meteorology Division in India , these high temperatures can lead to extreme weather conditions such as intense thundershowers , cyclones and cloud burst activities .
2 . Total Ground water of Earth Measured
The total amount of groundwater on the planet , in rock and soil , is estimated to be 23 million cubic km . This volume is equivalent to cover the Earth ' s entire land surface under some 180m deep water . The new calculation comes from a Canadian-led team and is published in the journal Nature Geoscience .
The report say that only - just 6 % - is the bankable water resource that is most useful to people . That small fraction is referred to as " modern " groundwater : it is extractable because it is near the surface , and can be used to supplement above-ground resources in rivers and lakes . This is the groundwater which is most quickly renewed – in human lifetimes . At the same time this modern groundwater is also the most sensitive to climate change and to human contamination . So , this vital resource needs to be managed better .
Some of the ground water is very quickly renewed , some are the older groundwater mostly stagnant and non-renewable . " Old water is highly variable ," Dr Gleeson told BBC News . In some places it is quite deep , in some places not . In many places , it can be poor quality . It may be more saline than ocean water and it can have lots of dissolved metals and other chemicals that would need to be treated before it could be used for drinking or agriculture .
Also writing in Nature Geoscience , Ying Fan , from Rutgers University , US , commented that " this global view of groundwater will , hopefully , raise awareness that our youngest groundwater resources - those that are the most sensitive to anthropogenic and natural environmental changes - are finite ".

3 . Climate change instigated Syrian Civil War .
Syrian civil war and emergence of IS has become a major concern for the Global politics in recent past . A recent study shows that severe drought , worsened by a warming climate , drove Syrian farmers to abandon their crops and flock to cities , helping trigger a civil war that has killed hundreds of
