evidence: Changes in the amount or rate of warming are much easier to detect in the OHC record than on the surface. For example, OHC shows little evidence of slowing down over the past eight years, despite a growing focus by climate sceptics on global surface temperature trends over that period. It also shows a distinct acceleration after 1991, matching the increased rate of greenhouse gas emissions over the past few decades. [...] While the world as a whole has warmed by around 1.3C since the pre-industrial period (1850-1900) in the Berkeley Earth dataset, land areas have warmed a much larger amount – by 1.8C on average. In contrast, the oceans have warmed more slowly – by around 0.8C since pre-industrial times. (See Carbon Brief’s guest post on why the land and ocean warm at different rates.) [...] The two lower-tropospheric temperature records show large differences after the early 2000s. RSS shows an overall rate of warming quite similar to surface temperature records, while UAH shows considerably slower warming in recent years than has been observed on the surface. Both have seen large adjustments in recent years that have warmed RSS and cooled UAH compared to prior versions of each record.
