London’s choked by leaving the EU

This month marks the 60th anniversary of the Clean Air Act, a piece of government legislation prompted in part by the Great Smog of December 1952 that caused between 4,000 and 12,000 premature deaths.boris

Air quality in the capital has vastly improved since those days of ‘pea souper’ fogs. A study of sunshine in Greenwich and other sites around east London reveals that winter months are, on average, around 18 per cent sunnier today than they were in the same period before the act was implemented in 1956. Though the cause of this is possibly partly because of a decline in winter anticyclones – weather systems that can give weeks of dull, murky conditions – further environmental legislation has helped.

Though the sky is clearer conditions at street level have grown steadily worse in recent years. During the first week of 2016 it was revealed that parts of the capital had already breached annual EU hourly limits for nitrogen dioxide – a pollutant that causes thousands of premature deaths through respiratory problems each year. A study last year showed that nearly 9,500 people die early each year in London because of long-term exposure to air pollution, more than twice as many as previously thought, according to the research.

Although action is being taken to reduce pollution from diesel buses, taxis and lorries the figures reveal that we are once again getting to the level of deaths caused by the Great Smog. The new mayor of London, Sadiq Khan, seems to be taking pollution a lot more seriously than his predecessor with a number of initiatives announced – making London compliant with EU legal limits well before the government’s target of 2025.

However, the mayor has also sent out conflicting messages by saying he backs the expansion of City Airport – you can’t have it both ways. And, if we do leave the EU, what will replace these EU legal limits?

With the current political situation lurching from one disaster to another I fear that the environment will get pushed well down the agenda. The current list of candidates vying to take over from David Cameron as prime minister include ‘dark horse’ Andrea Leadsom, the energy and climate change minister, who has been an ardent supporter of fracking. And on coal she recently sparked controversy in February  where she assured the industry the pledged 2025 coal phase-out was just a consultation and encouraged it to suggest what ‘unabated coal’ means.

The many benefits of EU membership got lost in the debate over the last few weeks – improvement in the environment being one of them. It is why, without the beady eye of Brussels keeping watch over us, that we must ensure that the next government stick to their promise of continual improvement to the capital’s air quality.

Winter sunshine totals were falling before we joined the EU. Since 1973 a general upswing is observed. On average there is 18% more sunshine during winter months since we joined the EU compared with the same period before joining the Common Market

June weather can be flaming horror show

The past week has produced the highest 24-hour rainfall total recorded in Wanstead since at least 1960. The multi-cell thunderstorm on Wednesday night saw 60.8mm fall, most of it in two hours, bringing flash floods to the surrounding area. The spectacular lightning and thunder that accompanied it was almost a side show such was the intensity of the rainfall.

I was unfortunate enough to be riding home right in the middle of the event: the entire length of the Mile End Road bore a resemblance to a shallow river, the heavy rainfall bouncing back off the Tarmac high enough to create what felt like a powerful drench shower.

The legacy of the downpours caused chaos in the morning and evening rush-hours. Many commuters were stranded at London terminals including Waterloo station because of flooded tracks, possibly robbing many of the chance of voting in the EU referendum. It will never be known if this would have had a bearing on the final result.

Many people think of June as a warm, summery month. The term Flaming June  is regarded in most peoples’ subconscious as a reference to past weather. That it is a actually the name of a painting is often missed. Looking back through our local history there has been many notable events of thunderstorms and prolonged rainfall. In 1903 a record-breaking 59-hour deluge left vast swaths of the borough inundated.

This weekend 200 years ago, during the Year Without a Summer, a powerful tornado, strong enough to carry away objects weighing 60lbs, tore through the Edgware Road area in west London. Luke Howard recorded the event in the Climate of London.

At two o’clock being a still sultry day a whirlwind passed over the nursery ground of Mr Henderson in the Edgware Road which lifted seven lights from the greenhouses and carried them to the height of the highest elm trees, each of the lights weighs 50 or 60lbs at least. At the same time two garden mats were carried to an immense height so that the eye could not distinguish them.

The following day “extremely heavy and prolonged rain from 9am (26th) to 9am on 27th gave 2.95 inches”. This total of over 52mm is notably high though not a record.

This weather was a continuation of what had been an awful May and June – cold with more than twice the average rainfall in June.

The weather then was not unlike what we have experienced this month. Indeed, a look at the weather throughout this year was similar as this graph shows.

compared

Though the mean temperature at times bears a close resemblance this year is no comparison to 1816: The mean then was running at 6.2C, over 3 degrees colder than today.
Mean pressure was also lower being 992.1mb; the 2016 mean 9am pressure is 1010.6mb.
Perhaps not surprisingly this year’s rainfall rainradaractually trumps 200 years ago; the running total for rainfall here is 390.1mm, higher than the 309.6mm recorded in 1816.

The dreary summer and frequent thunderstorms of 1816 inspired Mary Shelley to write Frankenstein. A summer vacation in Switzerland led her to spend much of the time indoors. She, along with Lord Byron and John William Polidori entertained each other with a contest to write the scariest story of all. The unseasonal conditions, along with this dare, led to the creation of Shelley’s Frankenstein: The Modern Prometheus— as well as Polidori’s novella The Vampyre and Byron’s long-form poem, The Darkness.

It will be interesting to see if this June’s weather, along with momentous political changes here and in Europe, produce more fine fiction from the this and the next generation of writers.

Brexit to bring back those halcyon summers

I’m joking. But with the lies and half-truths spouted by both sides of the EU referendum debate it is a statement I wouldn’t be surprised to hear uttered in this last full week of campaigning before June 23.

This preposterous statement, however, got me thinking that perhaps there may be some truth that summers really were better before Britain joined the then European Economic Community with Denmark and Ireland in 1973.

But comparing the past 43 London summers with the period of summers from 1930-1972 shows that this is not the case in terms of temperature and rainfall.

Perhaps it is just our minds playing tricks on us when we think back to summers being better than what they are today, and before EU membership?

Voter turnout and the weather

Over the years it has been argued that weather can affect voter turnout and therefore the result of an election. One Dutch study states: “We find that the weather parameters indeed affect voter turnout. Election-day rainfall of roughly 25 mm (1 inch) reduces turnout by a rate of one per cent, whereas a 10-degree-Celsius increase in temperature correlates with an increase of almost one percent in overall turnout. One hundred percent sunshine corresponds to a one and a half percent greater voter turnout compared to zero sunshine.”

Weather for the referendum on June 5, 1975, was mostly fine nationwide. A temperature of 21.3C was recorded at Greenwich after an overnight low of 7C. It was the start of a settled period of summer weather that had followed a cool and miserable late May and early June. Sound familiar?

In June 1975 the electorate expressed significant support for EEC membership, with 67 per cent in favour on a 65 per cent turnout. Though the turnout looks low you certainly couldn’t blame the weather.

In terms of this year, with ten days to go, it is too early to say for sure what the weather will be like on June 23rd though the GFS model suggests, like 1975, it could be the start of a more settled spell of weather?

Weather forecasting and the European Union

Weather forecasts have improved immensely since the 1970s. A three-day forecast is now much more accurate than a 24-hour forecast was in the 1980s, partly thanks to the collaboration between national met agencies throughout Europe and beyond.

The European Centre for Medium-Range Weather Forecasting (ECMWF), formed in 1975 as an intergovernmental organisation located in Reading, UK, will maintain its independence in the event of Brexit.

A spokesperson for ECMWF said: “While most of ECMWF’s member states are also members of the EU, ECMWF is structurally independent of the EU. The location of ECMWF in the UK, as well as the UK financial contributions to ECMWF and the tax arrangements between ECMWF and the UK are regulated by agreements between the ECMWF, its member states and the UK. These arrangements are entirely separate from the UK’s EU membership.”

There’s a huge amount riding on this referendum. The EU has flaws but there’s far more good comes out of it than bad. And even if the EU has too many technocrats and bureaucrats I’d rather entrust funding to them than the short-term policy making that plagues modern Westminster on both sides of the political spectrum. And that’s why I’ll be voting Remain.
