Reinventing the wheels

Skateboarding made its debut at the Olympics. Who invented the skateboard? — There are many reports of homemade skateboards being created in the 1940s and 1950s by Californian surfers who wanted to continue a form of their sport out of season, but the first commercial skateboard was marketed by roller-skate company Roller Derby in 1959. The sport, however, failed to catch on until 1973, with the introduction of urethane wheels and a curve at the end of a board known as the ‘kick-tail’, which allowed acrobatics to be performed.

There was more surface flooding in London. Is heavy rain becoming more common in London? The Met Office uses different ways to measure long-term rainfall trends.

1. The average rainfall on days when rain exceeds 1mm:

1961-90 6.5mm

1981-2010 6.8mm

2010-2019 6.7mm

2. Number of days in a year when rainfall exceeds the 95th and 99th percentile of daily rainfall in that location:

95th percentile

1961-90 7.7

1981-2010 8.8

2010-19 8.5

99th percentile

1961-90 1.6

1981-2010 1.8

2010-19 1.7
