Salón n de Acto os Julio Re ey Pastorr, Faculta ad de Cien ncias Mattemática as (UCM), Pla aza de lass Cienciass, 3 28040‐Madridd Absstract Over th he industriial period the surfac e temperaature of the Earth haas increase ed by abou ut 1C. O Overwhelmingly scien ntists are oof the opinion that th his is largelly due to the effect o of gases rreleased into the atm mosphere bby human activities. How can w we be sure e that this is the casse? Does itt matter? What can we say ab bout the fu uture? Thiis talk will outline th he evidencce for clim mate change, in tem mperature and othe er measurees, both globally g an nd regionaally. These will be se et in the coontext of natural variations in climate, what w is weell known and what less certaiin. The clim mate refleccts a delica ate balancee between n the energgy comingg in from th he Sun and d the heat energy leaaving the planet for s pace, and the talk will describ be how this can be d disrupted bby increasing concentrations off “greenho ouse gases””, especiaally carbon n dioxide (CO2). It w will be shown how basic phyysics can be used to t constru uct computer models of the cclimate wh hich can th hen be em mployed to investigatte climatee processess and what increasinng CO2 leve els may mean for th e future. T The talk will conclud de with a discussion around d ifferent ap pproaches to tacklingg climate change an nd where the world is headingg followingg the Unite ed Nationss climate c hange neggotiations iin Paris in n Nov/Dec 2015.
