It's not possible to use data from a single year to determine changes in long-term rates with high confidence. There's always the possibility that current conditions represent an outlier that won't be repeated for another decade. However, warming rates under business as usual (the track we are definitely on in terms of fossil fuel production and consumption) are expected to increase: > "According to NOAA's 2021 Annual Climate Report the combined land and ocean temperature has increased at an average rate of 0.14 degrees Fahrenheit ( 0.08 degrees Celsius) per decade since 1880; however, the average rate of increase since 1981 has been more than twice as fast: 0.32 °F (0.18 °C) per decade." https://www.climate.gov/news-features/understanding-climate/climate-change-global-temperature https://www.climate.gov/news-features/understanding-climate/... Models point to a transition to a higher rate of warming over the latter 3/4 of the 21st century (see projected temperature chart) that looks, eyeball-wise, close to double the current rate. Practically, this means instead of taking about 10 years for the trend to clearly emerge from the noise, we'll start to see it only take about 5 years. This could be headed off by an immediate elimination of fossil fuels from the energy mix, but even under the most optimistic scenarios that would probably take three decades of investment into renewable manufacturing at a rate around 3X greater than at present - and every fossil fuel sector on the planet is currently planning to maintain production at current levels for the next three decades. Demand for electricity is high and even if we ramp up renewable production that capacity could be entirely absorbed by the developing world while fossil fuel use remains constant. Adaptation is thus essential, although even this is being blocked by the climate denialist crowd, who still doesn't want to admit there's a problem.
