This programme provides an insight into climate change, the change in our world and a change in the way scientists view it.

Professor Andrew Watson of the University of East Anglia delves into the chemistry of water, to report on a potentially alarming consequence of climate change: acidification of the world's oceans.

Dr David Pearce of the British Antarctic Survey talks about the isolated, extreme continent of Antarctica, which has many biological secrets still waiting to be unlocked that may soon be lost as a consequence of climate change.

Dr Brian Cox describes work at CERN, the European organisation for nuclear research, in Switzerland, where physicists are attempting the most ambitious experiment of all time, recreating the conditions a tiny fraction of a second after the big bang.
