The three mature gentlemen of the Masqueraders sang their love song Average Guy - which they wrote 50 years ago.'You guys have that feel good effect on everybody,' said Mel, while noting that the 'over produced' music 'spoiled it' for her a little.'All I want to hear is you guys and your harmonies,' she said.'I absolutely love you,' gushed Simon.Arizona singer Evie Clair pulled heart strings with a story about her critically ill father.'I have to give 100 percent because that's what my dad is doing, and I want to be like him,' said Evie, who sang Wings by Birdy.

K., the Earth’s average temperature warmed by 1.4ºF (0.8ºC) between the 1850s and 2000s, mostly during 1911-19-1998: * Sources of uncertainty in surface temperature data involve “very incomplete” temperature records in the earlier years,[58] “systematic changes in measurement methods,”[59] “calculation and reporting errors,”[60] [61] [62] [63] [64] [65] [66] data adjustments that are performed when instruments are moved to different locations,[67] instrument precision,[68] instrument positioning,[69] and missing documentation/raw data.[70] [71] definitive assessment of uncertainties is impossible, because it is always possible that some unknown error has contaminated the data, and no quantitative allowance can be made for such unknowns.[72] * Oceans constitute about 71% of the Earth’s surface.[73] Changes in air temperature over the world’s oceans are typically based on measurements of water temperature at depths varying from less than 3 feet to more than 49 feet.[74] [75] This data is combined with changes in air temperature over land areas to produce global averages.[76] [77] contrasted water and air temperature changes in the tropical Pacific Ocean using three sources of measurements.

One of these was a series of buoys, each containing thermometers located ten feet above the water and at one foot below the water.

First of the night was Southern California dance group Brobots & Mandroidz.'I just wasn't getting the wow,' said Howie Mandel, but everyone else disagreed.'There were so many wows,' yelled Mel, who was sporting a new cropped, silver hair do.

Next was the 'little girl with big dreams' Celine Tam who sang Whitney Houston's When You Believe.

By comparing data from poorly positioned stations with other stations that are properly positioned, the study determined that the temperature irregularities in the poorly positioned stations cancel one another so that their average temperature trends are “statistically indistinguishable” from the properly positioned stations.

As of July 2015, no similar study has been conducted on a global basis.[81] * From 1979–2014, the three temperate datasets posted above differed from one another by an annual average of 0.13ºF (0.07ºC).

Magician Eric Jones did an impressive card trick involving a poker chip and a pane of glass.'Incredible!

' Exclaimed Mel, 42.'I think you're great,' said Simon who advised Eric to work on his 'showmanship' to make it further.

The 12th and final performer was Simon's Golden Buzzer pick - singer Mandy Harvey, who went deaf as a teenager after an illness.
