The climate records just keep rolling in . Month after calendar month , we keep collide with above - average temperatures , setting newfangled records that are only to be broken yet again further down the line . This October , however , has blasted all others out of the water . Not only will it pretty much guarantee , with a 99.9 percentage probability , that 2015 will be the human beings ’s hottest year ever recorded , butit was also the first monthto exceed NASA ’s middling temperature data by more than 1 ° C ( virtually 2 ° degree Fahrenheit ) .
Rather than using pre - industrial levels as a baseline , NASA used an average from between 1951 and 1980 as their starting point , which already includes a sure degree of globose heating . Even so , this October smashed that norm . In fact , it was so red-hot , it goes down as thewarmest monthever recorded in NASA’sentire database . This basically makes sure the forecasting that 2015 will see average global temperatures breach 1 ° blow of warming since pre - industrial level .

agree to NASA ’s data , the spheric average temperature for October of this yr was a shocking 0.2 ° C ( 0.36 ° F ) warm than for the same stop last twelvemonth . All this warming has intend that the last time the world saw a record dusty yr was in1911 . Unfortunately , 13 out of the 15 hot class on record have all happened since the year 2000 . It now seems that rather than retard down , we ’re instead driving full steam forward to the point at which the major planet will no longer be able to recover .
The reason behind these records is depressingly familiar , mainly being down to human - driven clime change . Increases in nursery gaseous state emissions are clearly having the predicted effect of warm not just land temperatures , but also the ocean too . thing have n’t been helped by one of the unsound El Nino events in recorded chronicle . According to theWorld Meteorological Organization , El Nino still has yet to touch its visor , which should be happening over the next few months and could see conditions patterns change even more dramatically .
All these criminal record are probable to precede another that the planet will hit next year . It looks likely that atmospheric concentrations of C dioxide are going to climb above400 parts per million , and will probably remain that way for our lifetime , taking decades to start falling again . This not only give to the tedious cooking of the planet , but also to ocean acidification , prevent molluscs from building their shells . Such temperature also contribute to theglobal red coral bleaching eventcurrently in progress from Hawaii to the Caribbean .
