Editing Geography of Tuvalu (section)

===El Niño and La Niña===
Tuvalu experiences the effects of [[El Niño]] and [[La Niña]] that flow from changes in ocean temperatures in equatorial and central Pacific. [[El Niño]] effects increase the chances of tropical storms and [[cyclones]]; while [[La Niña]] effects increase the chances of drought conditions in Tuvalu. On 3 October 2011, drought conditions resulted in a state of emergency being declared as water reserves ran low.<ref name="SPC2011">{{cite web|url= http://reliefweb.int/report/tuvalu/tuvalu%E2%80%99s-crippling-drought-offers-important-lessons-pacific|title= Tuvalu's crippling drought offers important lessons to the Pacific  |work= Secretariat of the Pacific Community|date= 6 October 2011|access-date=24 April 2015}}</ref><ref name=Tele>{{cite news| url=https://www.telegraph.co.uk/news/worldnews/australiaandthepacific/tuvalu/8804093/Tuvalu-to-run-out-of-water-by-Tuesday.html| location=London | work=The Telegraph| first1=Matthew| last1=Benns| title=Tuvalu 'to run out of water by Tuesday'| date=3 October 2011}}</ref><ref name=AM>{{cite web| first= Alistair |last= Macrae|url=http://www.abc.net.au/unleashed/3497128.html|title= Tuvalu in a fight for its life| date =11 October 2011|publisher=The Drum – Australian Broadcasting Corporation |access-date=12 October 2011}}</ref> Typically the islands of Tuvalu receive between 200mm to 400mm of rainfall per month, however a weak [[La Niña]] effect causes a drought by cooling the surface of the sea around Tuvalu.
