Overview of climate changes

Temperature changes

The unweighted mean difference across calendar-month temperature means was an increase of +2.56 °C; this summarizes the set of monthly means rather than describing every month or a continuous change between the reference periods. The metric is monthly mean temperature, not daytime highs. The largest monthly increase was in January, with a difference of +5.67 °C, highlighting a particularly strong change in that month's average.

Changes in snowfall

Mean daily snowfall averaged across calendar months showed a decrease of -0.25 mm/day. This is an unweighted summary of monthly means, not a monthly total, and does not imply the same change in every month. The largest monthly increase occurred in December, with a difference of +2.80 mm/day; the largest monthly decrease was in February, at a difference of -2.48 mm/day. The opposing monthly changes provide important context for the overall average.

Changes in rainfall

Averaged across calendar months, mean daily rainfall had an increase of +0.16 mm/day. This unweighted mean difference summarizes monthly averages, not monthly rainfall totals or a change that occurred uniformly throughout the year. The largest monthly increase was in May, at a difference of +0.71 mm/day, while July recorded the largest monthly decrease, a difference of -0.46 mm/day. These contrasting monthly shifts show why the overall mean does not describe every month's daily rainfall.

Changes in sunshine duration

Mean daily sunshine duration changed little in the unweighted average across calendar months, with a difference of -0.02 hours/day. The monthly extremes moved in opposing directions: July had the largest increase, a difference of +0.60 hours/day, whereas January had the largest decrease, a difference of -0.70 hours/day. The near-zero mean should therefore be read as an aggregate across months, not as evidence that daily sunshine was unchanged in each month.
