Overview of climate changes

Temperature changes

Across calendar months, the unweighted mean difference in monthly mean temperature was an increase of +2.17 °C compared with the earlier reference period; this summarizes the monthly averages rather than a day-weighted annual average, and monthly means are not daytime maximum temperatures. The largest monthly increase was in July, with a difference of +3.77 °C. This identifies the strongest increase among the supplied monthly comparisons, not a continuous change through time.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had a difference of -1.69 mm/day compared with the earlier period. This is an unweighted summary of monthly means, not an annual total or a description of every month's rainfall; the measurements are daily averages rather than monthly accumulations. The largest monthly decrease was in July, with a difference of -6.57 mm/day. By contrast, the largest monthly increase was in February, at +0.43 mm/day, showing that the monthly differences did not all point in the same direction.

Changes in sunshine duration

Mean daily sunshine duration increased by a difference of +0.46 hours/day when averaged across calendar months. This unweighted mean of monthly averages does not imply the same change in every month. The largest monthly increase was in July, with a difference of +2.06 hours/day. In November, sunshine instead had a difference of -0.08 hours/day, the largest monthly decrease; both are monthly mean daily hours, not measures of every day's conditions.
