There's also observations of what's changing environmentally and biospherically, of course, independent of actual temperature measurements. I actually think those have stronger resonance.
But those are far more subjective in my opinion because the issue has now become so politicized as to be polarizing as we see accusations of advocacy and denial being made from two camps entrenching rather than collaborating.
While this part is business as usual here where we have a divided body politic the whole issue is largely ignored in those areas where daily survival among many peoples of different faiths, origins and class is the overwheming crux of the expense of energy, both personal and governmental.
