Having explained the science behind global warming, and addressed the arguments of the climate change sceptics earlier in the series, Dr Iain Stewart concludes the series by looking at the biggest challenge now facing climate scientists - Just how can they predict exactly what changes global warming will bring?
It's a journey that takes him from early attempts to model the climate system with dishpans, to supercomputers, and to the frontline of climate research today: Greenland. Most worryingly he discovers that scientists are becoming increasingly concerned that their models are actually underestimating the speed of changes already underway.

In this historical drama, the turbulent transition from Roman republic to autocratic empire, which changed world history through civil war and wars of conquest, is sketched both from the aristocratic viewpoint of Julius Caesar, his family, his adopted successor Octavian Augustus, and their political allies and adversaries, and from the politically naive viewpoint of a few ordinary Romans, notably the soldiers Lucius Vorenus and Titus Pullo and their families.
'The Stolen Eagle.' In Gaul in 52 B.C., two Roman soldiers, Legionary Titus Pullo and Centurion Lucius Vorenus, are tasked with recovering Julius Caesar's personal Eagle, stolen from his camp in the dead of night. With his campaign in Gaul coming to a successful conclusion, Caesar's popularity is continuing to grow. He's saddened however when he receives news from his good friend Pompey Magnus that his daughter, Pompey's wife, has died in childbirth. In the Senate, Pompey must defend the prolonged absence of his friend and co-Consul Caesar against charges of corruption.

With Caesar quickly advancing toward Rome, Pompey begins ordering a retreat and forces his citizens to pick sides. Timon does Atia's dirty work and Vorenus cannot understand why no one is resisting while on a scouting mission.

Caesar contemplates Pompey's counteroffer but Mark Anthony wishes the war. Vorenus continues to struggle as a businessman and must reevaluate his career choice. Atia schemes to come between Caesar and Servilia and Pullo seeks Octavian's help.

Vorenus and Pullo return to the Collegium in Rome with Vorenus' family, but some of the 'changes' that Pullo had warned him about regarding his two daughters Vorena both the Elder and Younger, as well as his wife's son, begin to manifest themselves into hostility and resentment.
But Vorenus is completely oblivious to this, and is too blissfully happy to return to the role of 'father'. Meanwhile, Octavian finally returns and manages to negotiate the Senate Consul's seat from a scheming Cicero.
