Global warming trend

Do you see the trend in this data? Climate skeptics claim that global warming stopped in 1998, but my eyes detect an uptrend in the temperature data across the last 30 years.

This is raw data from the 5 best-known global and hemispheric temperature time series. It shows combined land and ocean temperature records.

Climate is a long-term average that reflects a great deal of short-term variability. Keep this in mind when anyone points to any trend of just a few years or a decade.
