Global warming took off in the mid-1970s when the rise in global mean surface temperature exceeded natural variability. Every decade after the 1960s has been warmer than the one before and the 2010s were the warmest on record. But there can be a lot of variability from one year to the next.
Now, in 2023, all kinds of records are being broken. The highest daily temperatures ever recorded globally occurred in early July, alongside the largest sea surface temperature anomaly ever.
