If you’re looking for a non-politicized (just the facts) site for global temperatures here’s a good one:
All it does is use the NOAA satellite data to measure the atmospheric temperatures. No more. No less. As a result, it doesn’t rely on readings ground stations which have tended to be somewhat inaccurate or affected by ambient temperature changes due to man-made construction (i.e. as an area gets urbanized, it gets warmer).
Regardless of where you stand on climate change, the numbers probably won’t make an advocate of either side very happy.
