From 12-foot snowdrifts in spring to wildfire three months later, extreme weather is becoming the new normal, writes Kames Capital's Georgina Laird.
With human-induced greenhouse gas emissions poised to cause even more disruption to global weather patterns, it is important to consider not only what effect it is having on the environment, but also on businesses.
Last year 15% of companies listed on the S&P 500 publicly disclosed that the weather affected their earnings - negatively in the vast majority of cases.
On average, adverse weather knocked 6% off earnings for those firms that chose to quantify the effect. In fact, over the past ten years, the words "climate" and "weather" appeared in earnings call transcripts more often than "Trump", "the dollar", "recession" and "oil", according to Bloomberg.
Food for thought
In the UK firms have also blamed the weather for poor performance. Next, Ocado and B&Q have all blamed the 'Beast from the East' for disappointing figures.
Of course, the weather affects industries in different ways. For example, British wine producers - long derided by connoisseurs - are set for a vintage year. Farmers, on the other hand, are struggling with the rising cost of straw and hay.
Either way, there is no denying that freak weather is having a huge effect on businesses - and even the biggest firms are not immune.
In April, Ryanair reported that bookings had been impacted by the warm European weather. Why go to Tenerife when the unusually balmy Lake District is on your doorstep?
Greggs, the nation's largest bakery chain, issued a profit warning in May, blaming the cold snap early this year for a sharp drop in sausage roll sales. In fact, Greggs is a firm that likes it neither too hot, nor too cold.
Hostile weather is even affecting gambling firms. Rank Group issued a profit warning in April, blaming the weather for a reduction in the number of visits to its Mecca bingo halls.
If, then, extreme weather conditions are here to stay, surely it only means one thing: firms must learn to adapt or face sharp falls in profits.
Logistics and transportation companies, for example, rely on weather and climate data to stay on schedule and reduce the risks of transporting often valuable goods.
Firms in other sectors must adopt some of the same techniques to protect earnings and shareholder returns. UPS, the delivery giant, has its own meteorology department, which helps them to prepare for major weather events.
While it is unreasonable to expect most firms to go that far, they should start making their own plans for dealing with unexpected future weather patterns as they are likely to become a more regular occurrence.
