UK Weather Trends #33 – Autumn 2024

December 4, 2024 By Nigel Marriott

The UK autumn in 2024 was essentially unremarkable and mostly consistent with the step change in autumnal climate seen 25 years ago.

UK Weather Trends #32 – Summer 2024

September 4, 2024 By Nigel Marriott

The 2024 meteorological summer in the UK was unremarkable on all weather variables.  In fact 2024 was so unremarkable that it is in fact the most “normal” summer of the last 114 years when I compare the data to the last 50 years which I regard as “living memory”.

UK Weather Trends #31 – Spring 2024

June 4, 2024 By Nigel Marriott

Spring 2024 in the UK was the hottest on record.  In some ways this is surprising given it was also the 10th dullest and 6th wettest spring on record which is inconsistent with trends over last 25 years and with the typical correlations seen in spring.  With any other dataset, I would ask for a check on the temperature data to see if it is correct.

UK Weather Trends #30 – Winter 2024

March 3, 2024 By Nigel Marriott

Winter 2024 in the UK was the 5th sunniest & 8th wettest on record.  A year ago I postulated UK winters were entering a new era of being warm, wet & sunny.  I am now certain this is the case and my favoured hypothesis is that our winters are following a steady trend which began in the early 1980s.

UK Weather Trends #29 – Annual Temperatures in 2023

January 4, 2024 By Nigel Marriott

The 2023 calendar year was the 2nd hottest year on record in the UK just behind the hottest year ever in 2022.  Last year, I showed how a technique known as a Control Chart could be used to decide if the UK is now in a new warming trend and after adding 2023, my answer is now “a step change upwards has taken place but the pace of change is not yet clear“.

Pay Gap Trends #7 – UK Ethnicity Pay Gap 2012 to 2022

January 3, 2024 By Nigel Marriott

In November 2023, the Office of National Statistics (ONS) resumed publishing estimates of the UK Ethnicity Pay Gap after a 3 year hiatus for the Covid19 pandemic.  I have organised this data into a user-friendly (hopefully!) Microsoft Excel spreadsheet which allows you to see how the median hourly pay has changed between 2012 & 2022 for a variety of ethnicities & other categories.  This article explains how you can use this spreadsheet and why you must look at ethnicity pay gap data in a different way than you would for gender pay gap data.

September 10, 2023 By Nigel Marriott

The hottest June on record resulted in the 8th warmest summer on record in the UK.  However, rain and sunshine levels were normal sowhen looking at the summer using principal components, the 2023 summer was above average but not outstanding.
