Heatwaves and Drought

As I write this post, the temperature in Greater London is 33°C (91.4°F). This has become a regular occurrence since the middle of May onwards. High temperatures are fine when you’re on holiday mainly because you’re off work and at your leisure. You don’t have to perform the usual daily task that life requires of you such as work, shop, cook, clean etc. Furthermore, if you’re on vacation you’ll probably be staying at a resort or hotel that is fully air conditioned and you’re dressed accordingly. However, if you’re still performing you’re daily routine such as commuting to work and spending time in an office that wasn’t built with such external temperatures in mind, then 33°C is frankly a pain in the ass. Oh and if you’re one of those people who always respond to discussions such as this with “well I live in Riyadh and it’s 40°C here”, please sod off. You live in a desert which is dumb to begin with. Plus this is not a commensurate comparison. Temperatures are rising in the UK. It’s always hot in Saudi Arabia.

Back the matter in hand, almost three-quarters of England is now officially in drought. Reservoir levels have fallen to 69%. That is 11.6% lower than expected for this time of year. There are already restrictions in place with regard to the use of water such as a hosepipe ban. The immediate prospects of a respite from such high temperatures is not likely at present and so the UK and Europe braces for its fifth climate heatwave this summer. As a result of the hot weather, UK farmers have reported their earliest harvests in 20 years, with reduced yields. Reduced domestic yields in core staples like wheat (down roughly 14%) and oats (down at least 9%) are driving fears of climbing food inflation later in the year. From a wider perspective the heatwaves and associated drought also have serious consequences for the UK economy. It is estimated that £3 billion to £4.4 billion has been lost as the result of lower or lost economic output.

On a personal note, because the last few summers in the UK have been getting hotter, we’ve bought several fans. Four to be precise. These are quiet, pedestal models that keep the air circulating in the main rooms of our home. We keep the curtains and blinds closed all day to stop the sun heating the rooms directly. However, we keep a few windows open to draw air in at the back of the bungalow and vent air out of the front. At present it is 27°C indoors but the flow of air makes it feel more tolerable. Due to the heat outside we tend not to go out unless we have too. Chores such as going to the supermarket are conducted early in the morning. Despite being an Englishman I won’t go out in the midday sun. So for the immediate future, all social arrangements are on hold and me and Mrs P are just staying indoors and trying to stay cool. Fortunately we are both able to occupy ourselves, so boredom is not yet an issue for the present.

The fact that the UK is currently enduring a continued period of record breaking temperatures, along with Europe, clearly indicates to me the validity of climate change. The data has been there for years, so I will have no truck with those who choose to refute it for political and financial reasons. However, although I eschew such people I can see why they act thus. They are motivated by financial and political gain. What annoys me more are those who try and argue against the data, despite having no fact based counter argument. Those who deny the reality of the situation because “their team” has encouraged them to do so. Wilful ignorance is a blight than runs through all western societies. However, I rather not end on a negative note, so let’s look to a positive. One individual who is having a great summer is our local ice cream man. He plies his trade down our street daily and is doing great business. So at least some good is coming from this unusual weather.

UK Heatwave

Temperatures are forecast to increase across the UK over the weekend. They have gradually risen over the last few days and are expected to reach the official “heatwave” threshold in some places for the third time this year. Highs of 34°C (93.2°F) are likely today and possibly on Saturday and Sunday, with above average temperatures continuing into early next week. The UK Met Office has predicted that south-east Wales, central southern and south-east England are likely to see the hottest weather. The UK Health Security Agency (UKHSA) has extended yellow heat health alerts to cover every region in England, which will remain in place until 10:00 BST on Tuesday 15 July. The warnings mean that health and social care services could be significantly affected by the weather, due to increased demand or a rise in deaths.

Such extremes of temperature are becoming common in the UK. Growing up, I have memories of the summer of 1976. The unprecedented heatwave led to drought conditions in rural areas and a temporary water shortage. That was an anomaly at the time and for many years it remained a talking point and source of nostalgia. Since then there have been periods that have met the heatwave criteria in 2018, 2019, 2021 and 2022. While linking climate change with specific individual extreme weather events can be difficult, scientists say climate change is generally making heatwaves hotter, longer and more frequent. UK temperatures over the next few days will be around 7-10°C (44-50°F) above average for mid-July. The main problem arising from this phenomenon is the country’s inability to cope. The UK’s infrastructure, architecture and institutions are predicated on the notion that the country has a temperate climate.

The UK is ill-equipped to deal with high temperatures due to a combination of factors. Older buildings are particularly vulnerable, often designed to retain heat in the winter but becoming excessively hot in the summer. I live in a brick bungalow that was built in the early 1930s. It has been insulated with modern materials and although it retains heat during cold weather it fails to prevent heat transfer during summer, causing indoor temperatures to rise significantly. Air conditioning is not a standard feature in most UK homes or on public transport, although the latter is getting better. Buses in London now have better climate control but travelling on the underground or railway is often unpleasantly hot. Also, simple solutions such as awnings and canopies are still not standard features on UK buildings.

Hence a heatwave in the UK is seldom universally welcomed. I personally find that once the temperature rises above 25°C (77°F) then I am out of my comfort zone. However, I have invested in several good quality fans in the last few years and although they only circulate the air, they do make things more tolerable. As for my definition of a “good quality” fan, it is defined by whether or not the device is quiet. Thankfully, my office is in the front of the house overlooking the street and facing North. The lounge at the back of the property looks out over the garden and gets a lot hotter due to the aspect and the glass patio doors. Subsequently, Mrs P and I keep the curtains and blinds shut all day in the lounge and kitchen and it does make a difference. Hopefully we will cope with the coming heatwave. Others may not be so lucky.

Countries that regularly face high temperatures usually develop an appropriate culture of safety and responsibility. The importance of staying hydrated and liberal use of sun protection products become an everyday part of life during the summer. Hats also become more than just de rigeur. There is also a heightened awareness of fire safety with rural areas being increasingly dry. Sadly, this mindset is not commonplace in the UK and many people are irresponsible once the weather gets hot. Hence, there are numerous cases of heat exhaustion, sunburn and dehydration. Sadly, pets also suffer in this weather. No doubt there will be increased reports of such in the UK media next week, although the tabloids will reserve the most vitriol for the various hosepipe bans that have been announced. In the meantime, stay cool. Literally.
