a) published data tends to see corrections from sensors and methodology which take several years to work out the fine details. (This isn't an attack this is science) Which means always take yesterday's numbers with more scepticism than 2yr ago. (This is making no statement of any data you're looking at or any trend you claim to see)

b) a field dominated by modelling needs data to back it up, otherwise the conversation would be, "Why is the LHC failing to find strong theory which is absolutely there" vs "I wonder if the modelling is correct based on..." This is a certain level of maturity that certain sciences are only starting to reach after playing in the ballpark of "let's go model my idea and make a press release which will just so happen to help my funding".

Yes sea level temps are rising, absolute numbers are still difficult to come by though and last UN summary doc I read still put things at 5C global average over a century. (Yes still horrifically catastrophic for the wrong people, but I'm also not in charge)
