Climate science is not my area, so I wouldn't want to comment on details... The wiki article suggests that earlier discrepancies between tropospheric and groun

  That article doesn't offer much information about how the discrepancy was resolved. I do know it is wrong in saying that the RSS troposphere shows more warming than UAH since 1998, because RSS shows zero warming since 1998. Don't trust me, please look at the data yourself. But the land temperature stations have a miasma of questionable adjustments hanging around them. The stations themselves are not often well situated for clean readings, and then when the data is adjusted for heat island effects, rural stations will be adjusted upwards far more than urban areas will be adjusted downwards. I can't imagine why rural stations would ever be adjusted upwards, except on a case by case basis. But either way, the confidence intervals become mere guesses. It's unconscionable to mix that data with the more scientifically rigorous satellite data. There's no getting around that the UAH and RSS sets show little to no warming for nearly 2 decades (RSS is 19 years and 6 months, and UAH 6.0 [most references to UAH will be 5.6 which is outdated] lines up nearly perfectly with RSS).
