Unknown

 * ATMOS, a combination GPS/emission control system for automobiles, becomes widespread in vehicles around the world.
 * Thousands of Adipose are born from peoples fat and walk around the streets. During this time, Donna Noble reunites with the Tenth Doctor and begins her travels with him. Before leaving with the Doctor, however, Donna briefly encounters Rose Tyler (although she is unaware of Rose's identity). (DW: Partners in Crime)
 * Conspiracy theorists begin noting the disappearance of bees from the planet Earth, which is also noted by Donna Noble. (DW: Partners in Crime, et al). It is later learned that they have left earth in anticipation of its imminent relocation to the Medusa Cascade (DW: The Stolen Earth).
 * The Sontarans invade Earth . During this event, Martha Jones is temporarily reunited with the Doctor and meets Donna Noble for the first time. Donna also narrowly misses witnessing a brief transmission from Rose Tyler in the TARDIS. As part of the Sontaran invasion plan, all ATMOS-equipped vehicles begin emitting a toxic gas intended to transform the world's atmosphere into a more hospitible one for Sontaran offspring; numerous fatalties are reported worldwide before the Doctor disables the devices. Afterwards, the ATMOS devices are removed from the planet's vehicles. (DW: The Sontaran Stratagem/The Poison Sky)
 * Rose Tyler temporarily returns from her parallel Earth, initially arriving in the normal universe (DW: Partners in Crime) but later ending up in an alternate timeline where she attains a position of authority with UNIT and works with them and Donna Noble to restore the timeline. (DW: Turn Left)
 * The Earth is relocated to the Medusa Cascade by the Daleks under the control of the Supreme Dalek and Davros. Despite the relocation, the planet retains a full communications network. An invasion of Earth by the Daleks commences and a number of humans are taken to "the Crucible", the Dalek mothership, where they are killed in tests of the reality bomb. As part of a counter-insurgency against the Dalek invasion, former Prime Minister Harriet Jones brings together a number of the Doctor's former companions, including Captain Jack Harkness, Sarah Jane Smith, and Martha Jones in order to contact the Doctor, and before she herself is killed by the Daleks. Rose Tyler, meanwhile, joins Donna Noble's family and is ultimately reunited with the Doctor. During this incident, The Doctor undergoes a partial regeneration in order to repair damage from a Dalek blast; as a result of this, the Doctor's severed hand later forms a mental link with Donna and grows into a second version of the Doctor, but one that's half-human without Time Lord biological abilities. The Doctor and his companions are successful in restoring Earth to its original location; this sparks worldwide celebrations around the planet. Afterwards, Mickey Smith chooses to remain on his original Earth instead of returning to Pete's World, Harkness offers Martha Jones a job with Torchwood 3, and the Doctor returns Rose and Jackie Tyler to Pete's World, along with his clone. Donna Noble is returned to her family with all memories of the Doctor wiped from her mind. (DW: The Stolen Earth/Journey's End)

Rose Tyler works with the UNIT of this timeline to help Donna Noble restore the proper chain of events which, at one point, involves sending Donna back to 2007. (DW: Turn Left)
