The show, which saw a group of celebrities competing to reach the freezing North Cape in Norway, will return for an 8-episode run without presenting duo Kate Thornton and Gethin Jones.
"It's very flattering to be part of the ITV family," Take Me Out host McGuinness said. "Ant 'n' Dec get to spend time in sunny Australia, Dermot O'Leary fronts the biggest show on television and Phil [Schofield] and Holly [Willoughby] enjoy a lovely day time gig by the Thames. What do I get, a month in the Arctic Circle! 'Let the frost... see the bite!'"
Sky Sports presenter Jackson, who recently hit the headlines in the Richard Keys and Andy Gray sexism storm, added: "It's going to be very cold but great fun. I am hugely excited to be a part of the new series."
The Sun claims that Loose Women host Thornton is believed to have stepped down from the role in order to 'focus on being a single mum', prompting bosses to go for a new-look team.
"Due to the change in my circumstances at home I was unable to travel to the Arctic. But I wish Paddy, Charlotte and the team the very best of luck," Thornton said. "I can't wait to catch the show in the warmth and comfort of my living room!"
A show source commented: "Without Kate, producers decided to go for a new presenting team. Gethin is busy recording a pilot for a new game show for ITV."
Writing on Twitter, Jackson confirm that she and McGuinness are beginning to film the new series today.
"Day 1 of filming 71 Degrees North -early start and never put so many layers on- ! very excited though! (sic)" she said. "Myself and Paddy Mcguiness will be meeting the 10 celebs today!"
The paper claims that the 10 celebrities taking part in the show include actor John Thompson, Spandau Ballet star Martin Kemp and presenter Angellica Bell.
71 Degrees North will return to ITV1 later this year.
