The Global Warming Tour, by American hard rock band Aerosmith, included 82 concert performances across North America, Oceania, Asia, Latin America, and Europe.

"It's something so magical," remarked Steven Tyler. "Other people see it. We don't, because we're in the middle of it. This is Aerosmith, man. The second we get up there on stage, it's insane."^[1]

Prior to the first leg, the band played a private event for Walmart shareholders. The first leg included 23 performances and lasted from late May through early August 2012.

The second leg included 14 performances in November and December 2012. Before the second leg, the band performed a brief set at the iHeartRadio Music Festival in mid September. Also prior to the second leg, to promote their new album in early November, the band played three nationally televised performances in New York City and did a special performance in front of their old Boston apartment.

The first two legs were held primarily in indoor arenas, with a couple outdoor shows and a few festivals on the first leg, including three in eastern Canada and Milwaukee's Summerfest.

The third leg of the tour ran from late April to mid May 2013 and saw Aerosmith playing their first shows in Australia since 1990, as well as their first shows in New Zealand and the Philippines. On May 30, the band played at the "Boston Strong" charity concert for victims of the Boston Marathon bombing. In July 2013, the band played at the Greenbrier Classic in West Virginia and at Foxwoods Resort Casino in Connecticut. In August 2013, the band performed four concerts in Japan, but their first shows in China and Taiwan were cancelled due to poor ticket sales. The band performed in August at the Harley-Davidson 110th anniversary concert series in Milwaukee. Concerts were planned for Latin America in September and October, including their first shows in Uruguay, Guatemala and El Salvador.

Cheap Trick opened all dates on the first two legs bar a few festivals.^[2] The Dead Dasies, featuring Jon Stevens and Richard Fortus, opened the Australia/New Zealand leg. In Argentina and Brazil, Aerosmith toured with Whitesnake, including the Personal Fest in Buenos Aires and at the Monsters of Rock in São Paulo.

The tour promoted Music from Another Dimension!, released on November 6, 2012.^[3] In addition to hits and choice album cuts, the band performed four new songs from the album, three of them regularly ("Oh Yeah", "Legendary Child", and "Lover Alot").

On May 5, 2013, the band announced they had cancelled their first show in Jakarta due to safety concerns.^[4]

In 2014, Aerosmith played 17 concerts across Europe from May 14 to July 2. The Let Rock Rule Tour was scheduled to follow in July, August, and September 2014 and see Aerosmith play several dates in North America. This tour featured Slash (with Myles Kennedy and the Conspirators) as the opening act. Full details of the tour were announced on April 8, 2014.^[5][6] On May 14, 2014, the band announced that they had cancelled their concert in Istanbul after Turkey declared a three-day mourning for the victims of Soma mine disaster.^[7] The July 2, 2014 concert in Kyiv was cancelled due to civil unrest in Ukraine.^[8]

The stage was very close to the design of past tours. The main stage, occupying one end of the venue had the classic Aerosmith logo painted on top and two small platforms off to each side. Kramer's drums were at the back, Hamilton and Whitford were on the left side, and Perry was on the right side. The back-up musicians were at the back-left of the stage behind a stack of amps, the order usually went Melanie Taylor (backing vocals), Mindi Abair (saxophone and backing vocals) and Russ Irwin (keyboards and backing vocals). In the middle of the main stage was the catwalk, which ran through nine rows at each venue. At the end of the catwalk was a B-stage, which ran through the tenth row to the sixteenth row. Around the entire stage was a half-meter wide barricade that contained security and a few select fans.

The show would start with a video playing on the main video screen that was reminiscent of the original opening from The Outer Limits. Near the end of the video, smoke would arise from the end of the B-stage and from the main stage. When the video finished, Kramer, Whitford and Hamilton would kick into the opening song while Tyler and Perry would rise from a trapdoor at the end of the B-stage. For the first song, Tyler and Perry would stay on the B-stage and the rest of the band would stay on the main stage. After the first song finished, Hamilton, Whitford, Tyler and Perry would all go where they pleased. At "What It Takes", Tyler would look for an attractive girl to sing the opening lines, like in most tours. At the encore which was "Dream On" at every date, smoke would again appear from the end of the B-stage and Tyler on a white piano would appear from the same trapdoor as before. The piano had a few blocks beside it used as stairs by Perry and Tyler, as they would walk on top of the piano. They followed with a second encore – "Train Kept A-Rollin'" – and at a few venues, a third encore was even played, either "Mama Kin" or "Chip Away the Stone". When the encores wrapped up, a few cannons fired silver confetti into the audience. After the confetti storm, Tyler would introduce the back-up musicians (Taylor, Abair and Irwin) and the members of Aerosmith. Finally, he would hand the microphone off to Perry, who would introduce Tyler. After the introductions, the band would walk out with "Mannish Boy" by Muddy Waters playing over the speakers.
