I’m sorry, I didn’t see your later post until after I posted the SSH images. My answer is no, this isn’t enough to affect decadal trends. The 1997-1998 El Nino was notable because it was so strong it pulled the 1998 temperature 0.2 C above the warming trend line.
The May 2007 lower troposphere temperatures are LOWER than the October 1979 temperatures.
So that makes 26 and a half years of no warming.
