"This point is outdated circa 1999. All weather ballon (radiosonde) and satellite (MSU) data records show tropospheric warming now."

Are they showing it because they have to make adjustments due to some error in satellite or balloon distancing? I'm very skeptical about any of those "corrective" measures. Also, explain to me why these scientists would be in agreement about this dated data? Laziness to read the latest reports?

It might be useful for you to do some Googling on the phrase "MSU tropospheric temperatures", or the words (together) MSU, troposphere, temperature. Basically, for many years the only analysis of MSU data headed by Roy Spencer and John Christy indicate little warming of the troposphere. After 1998, this analysis showed a little warming. But subsequent analysis of their work showed processing errors. Correction of these errors resulted in a significantly increased warming trend in THEIR analysis. The groups that uncovered the errors (and who actually worked with Spencer and Christy on the corrections) also did independent analyses of the same raw data and derived significantly greater warming trends than Spencer and Christy. Radiosonde trends have been examined for correlation; look up James Angell for some additional information.

So the current analyses all show warming trends of various magnitude. Spencer and Christy's analyses is still the smallest warming trend.
