The Met Office have issued a pretty interesting summary of Junes weather.

In it they conclude that it was almost 1c warmer than the previous record. The previous 3 records were separated by 0.1c. Their study shows that climate change makes these sort of statistical jumps more likely than in the past and will make them increasingly more likely into the future.
