They do?! Haha.
On the other hand, you also took the bananas blip 2023/2024 at the end of your global air temperature time series as proof that the warming rate had increased.
But for example, the North Atlantic #ocean basin which had contributed to the
years is now back down to the bulk body of previous years, 0.5°C cooler than 2024, 0.6°C cooler than 2023.

The
blip in global sea surface temperature – as contributor to global air temperature – is possible as a once-every-500-years outlier in CMIP6 under current warming as Terhaar et al just published in March https://www.nature.com/articles/s41586-025-08674-z
My line chart shows temperature data from weather stations outside the direct impact zone of #ElNino, Hohenpeißenberg
, Jena
and Oxford
since 1815 (– altho I did learn from your paper that #ENSO does impact North Atlantic weather too by tickling the Azores High somehow? So ENSO also affects European temperature.).
Shown is their 5-year running average, their 20-year stepwise average, and their 210 year linear trend through to week 11 in 2025.
The differences in their last two 20yr steps increased too.
From the warming step
1965-1984 to 1985-2004
versus the step 1985-2004 to 2005-week 11 in 2025:
0.83 vs 0.99
, increase of 0.16C
0.66 vs 0.82
, increase of 0.16C
0.77 vs 0.82
, increase of 0.05C
But I guess, 
is due to SO2 filters in coal-fired power plants and the loss of that cooling effect. Of which Oxford experienced less in my line of thinking because Germany is downwind of all Western European coal power plants and used to receive their cooling SO2 until regulation against acid rain from the Montreal Protocol took effect.
I like the chart because it teaches me the effect of averaging and linear trend.
At which °C the last 5-year average ends, versus the end of the linear trend across all the 210 station years:
8.9 vs 7.4
11.2 vs 10
15.7 vs 14.9
The most recent year in Hohenpeißenberg was in 2001 where the average of the previous 5 years matched the very end of the linear trend at 7.4C .
So the linear trend practically shaved off everything since then, all the heat deaths, human, plant or animal, all the floodings, all the losses in hail storms and so on, that occurred due to the added warming since 2001.
The 5-year rolling average also erases such extreme climate events from memory. London's 40°C in 2022 as well as the flooding in Belgium and west Germany in July 2021 known as #Ahrtal event to Germans.
How much and how many such events are lost in line charts of global averages?
I guess, global civilisation collapsing from regional impacts of +1.5C warming won't show as blip in such a chart. But damages to fragile supply chains and societies do occur and pile up – while people still pore over GMT.
