mainly dry. Sunshine and showers on the 19th and 20th, the showers locally thundery at times in the south. Rain spread north-eastwards on the 21st and it turned very mild in the south with highs of 14.6 °C at Yeovilton (Somerset) and Exeter Airport (Devon). The following night was also very mild
decade (2009-2018), have been on average 5% wetter than 1981-2010 and 12% wetter than 1961-1990. Summers in the UK have also been wetter, by 11% and 13% respectively. However, very long-period natural variations are also seen in the longer observational record. These show periods in earlier parts
air persisted at times in the north, resulting in some snow at the frontal boundary. Storm Christoph brought very wet and windy weather between the 19th and 21st, with many stations having over 100 mm of rain. It was colder from the 22nd to 25th with snow in places, mainly in the west
pulses of electro-magnetic waves, which travel at the speed of light (approx. 186,000 miles per second), are transmitted in a narrow beam for a very short time (typically two microseconds). When the beam hits a suitable target, some of the energy is reflected back to the radar, which ‘listens’ out
cold winters in 1881, 1895 and 1962-3 (when the upper Thames froze over) the Thames has not frozen over sufficiently to allow a Frost Fair since 1814. This is largely due to changes in the river and its built environment. The Thames of the past is very different from that of today. The wider
, thunderstorm warnings were issued for parts of Wales and southern England. A very localised storm affected Criccieth (Gwynedd) on the 3rd, with surface water flooding along the town’s main street, manhole covers being forced up and a few properties being inundated. The following day saw surface water flooding
and 12% wetter than 1961-1990. Summers in the UK have also been wetter, by 11% and 13% respectively. However, very long-period natural variations are also seen in the longer observational record. These show periods in earlier parts of the historical record with similar levels of UK summer rainfall

for the first time a pathway that shows emissions peaking this decade due to policies put in place because of the energy security crisis globally. 2022 Met Office COP27 webinar However, while some progress is clearly being made, it is very limited progress. Every fraction of a degree counts towards
