If we are experiencing additional warming from increased greenhouse gasses
regardless of source, how would these changes manifest themselves?
This is not a question of what others think, but what you as individuals
think based on Science backgrounds, life experience, phase of the moon, whatever.
I will start.
If increased greenhouse gasses are slowing down the energy escaping the earth,
I think we should see less separation between the high and low temperatures within
a daily cycle.
The highs might be the same, but the morning lows would not be as low.
Also the cool down curve would be more gradual.

Yes, loss of heat into space would be slower, so cool-down at night would be more gradual, all things being equal. But it would be difficult to measure this because the effect so far, from an increase of CO2 in the atmosphere of 120 ppm, would be pretty small. Humidity has a much larger effect on cooling at night, and humidity varies all the time. A sky overcast with clouds would also have a much larger effect on cooling at night than an increase of CO2 of 120 ppm.

Another change that observed would be a change in the latency of the seasonal
heating and cooling.
The summer and winter solstice are the longest and shortest days of the year,
but the hottest and coldest days occur about 6 weeks after.
I wonder if this number is changing?

You are absolutely correct. This would be an indicator of additional greenhouse forcing rather than additional solar forcing. LowDown is also correct that this isn't the easiest thing to measure.

Another indicator is temperature changes across various altitudes. Additional solar forcing would generally show a temperature increase across all altitudes, while additional greenhouse forcing should show an increase in temperature near the surface but cooling in the upper layers of atmosphere.

I had an Idea that might be a test of sorts.
Sierra Vista, AZ and Savannah, GA are near the same latitude,
So absent other factors receive about the same number of hours of sunlight
at the edge of the atmosphere.
Weather History for Sierra Vista, AZ | Weather Underground
Weather History for Sierra Vista, AZ | Weather Underground
I picked a custom time between April 21, 2012 and Sept 21, 2012 in both places.
While it is hard to see on the graph, the AZ site has the hottest average days
from about June 22 to July 6.
the GA site the average hottest days are between July 7 and July 20.
Many factors influence why the hottest period is offset,
but the Airs Satellite shows AZ has slightly higher Co2 levels than GA.
Ideas?, comments

No answers on this question, I see. I don't have any either. It's a good question.

Albedo. Cloud cover. Predictable and seasonal. Color of the earth. Altitude. Along uphill or downhill slope to distort angles of absorption or reflectance.
