If the first two decades show no warming, how does El Nino justify 3 decades of +.13degC/decade?
Fixes in data and analysis?
Isn’t that how they got into trouble in the first place?

If the first two decades show no warming, how does El Nino justify 3 decades of +.13degC/decade?

The 1997-1998 El Nino was so big that it yanked (statistically) the uncertain trend upward. Even despite the ensuing cool La Nina, the subsequent warmer years maintained the established trend.

Here's the current data.

Fixes in data and analysis?

In part, yes, Spencer and Christy had to fix some things. This also helped increase their reported trend.

Isn’t that how they got into trouble in the first place?

I think you're thinking of a different group. Spencer and Christy are notable skeptics with true scientific credentials (which forces them to admit some non-skeptically-aligned things at times).

I’ll stick with the raw data.

Whatever works for you.
