We know that the \href{http://www.bom.gov.au/climate/enso/}{El Ni{\~n}o-Southern   Oscillation} is the main source of year to year temperature variability in the   oceans. It occurs in the tropical Pacific but is strong enough to have a global   influence.\\   We can take our climate model again but instead of assigning the   whole ocean temperature we just put in a "fake" El-Ni{\~n}o/La-Ni{\~n}a.   We make the tropical Pacific ocean temperatures go up and down - over   a period of four years - and let the rest of the ocean, and the land, respond.\\   In this experiment, the global land surface temperature still   responds with amplified variability relative to the ocean, so if the ocean surface temperature increases or decreases by $1^{\circ}$ the land temperature will increase or decrease by almost $1.5^{\circ}$. Essentially, we can   control the global land temperature by changing the temperature of the tropical   Pacific ocean. \\  diff --git a/layout.md b/layout.md  index 73f065a..8508bfc 100644  --- a/layout.md  +++ b/layout.md
