Thanks for hanging in there, Eli...First off, by using only a single straight line to represent
graphed data puts you at risk of missing the kind of acceleration that's taking place with Dr. Spencer's measurements over the last 12 years. If you do some research on this, you'll get this kind of response...

"Why a Straight Line Hides Acceleration"
> It assumes a constant rate of change: A straight line has a single, unchanging slope. Acceleration, by definition means the slope is changing (getting steeper) over time.
> It averages out the details A single line of best fit through accelerating data will typically understate the data points at the beginning, overstate them in the middle, and understate them again at the end, smoothing out the exponential or quadratic curve

Note that Dr. Spencer is an avowed CC Threat denier...so a Straight Line presentation works for his premise, and hides the very obvious 'Acceleration' over the last 12 years that is in contrast to the flat periods prior.
Now, as for the Super El Nino we are experiencing...please don't be like some others on this forum and hide your eyes....just read the attached link that presents the reasoning for a linkage between these recent extreme El Nino storms...and Climate Change.
Admittedly, there is an active debate going on...but don't forget that the NOAA Atmospheric CO2 concentration data from Mauna Loa Observatory is Rock Solid...and the Human FF Burning sourced component (with No C-14 present) is readily identified ---> showing sharply Increasing amounts...e.g. a range from 180 - 300 ppm over 800,000 years...to 425 ppm in just ~150 years. THATS what you call "ACCELERATION"....and it's virtually ALL Man Made.
I assume you have a Scientific/Engineering background as I do...don't hesitate to ask for clarifications...as I will of you.
Bottom Line:...I maintain my contention that global Tropospheric temperatures are increasing at an Accelerating Rate.
