4 ways extreme heat hurts the economy – The Conversation US

Summer 2021 will likely be one of the hottest on record as dozens of cities in the West experience all-time high temperatures. The extreme heat being felt throughout many parts of the U.S. is causing hundreds of deaths, sparking wildfires and worsening drought conditions in over a dozen states.

How does all this broiling heat affect the broader economy?

As an economist who has studied the effects of weather and climate change, I have examined a large body of work that links heat to economic outcomes. Here are four ways extreme heat hurts the economy – and a little good news.

1. Growth takes a hit

Research has found that extreme heat can directly hurt economic growth.

For example, a 2018 study found that the economies of U.S. states tend to grow at a slower pace during relatively hot summers. The data shows that annual growth falls 0.15 to 0.25 percentage points for every 1 degree Fahrenheit that a state’s average summer temperature was above normal.

Laborers in weather-exposed industries such as construction work fewer hours when it’s hotter. But higher summer temperatures reduce growth in many industries that tend to involve indoor work, including retail, services and finance. Workers are less productive when it’s hotter out.

2. Crop yields drop

Agriculture is obviously exposed to weather: After all, crops grow outdoors.

While temperatures up to around 85 F to 90 F (29-32 C) can benefit crop growth, yields fall sharply when thermostats rise further. Some of the crops hit hard by extreme heat include corn, soybeans and cotton. These reductions in yields could be costly for U.S. agriculture.

For example, a recent study I conducted found that an additional 2 degrees Celsius of global warming would eliminate profits from an average acre of farmland in the Eastern U.S.

A prominent example of this was the collapse of the Russian wheat harvest in response to the country’s 2010 heat wave, which raised wheat prices throughout the world.

3. Energy use soars

Of course, when it’s hot, energy use goes up as people and businesses run their air conditioners and other cooling equipment at full blast.

A 2011 study found that just one extra day with temperatures above 90 F increases annual household energy use by 0.4%. More recent research shows that energy use increases the most in places that tend to be hotter, probably because more households have air conditioning.

This increase in electricity use on hot days stresses electric grids right when people depend on them most, as seen in California and Texas during recent heat waves. Blackouts can be quite costly for the economy, as inventories of food and other goods can spoil and many businesses either have to run generators or shut down. For instance, the 2019 California blackouts cost an estimated $10 billion.

4. Education and earnings suffer

A long-term impact of increasingly hotter weather involves how it affects children’s ability to learn – and thus their future earnings.

Research has shown that hot weather during the school year reduces test scores. Math scores decrease more and more as the temperature rises beyond 70 F (21 C). Reading scores are more resistant high temperatures, which this research claims is consistent with how different regions of the brain respond to heat.

One study suggested that students in schools that lack air conditioning learn 1% less for every 1 degree Fahrenheit increase in the school year’s average temperature. It also found that minority students are especially affected by hotter school years, as their schools are especially likely to lack air conditioning.

Lost learning results in lower lifetime earnings and hurts future economic growth.

The impact of extreme heat on development, in fact, begins before we’re even born. Research has found that adults who were exposed to extreme heat as fetuses earn less during their lifetimes. Each extra day with average temperature above 90 F (32 C) reduces earnings 30 years later by 0.1%.

Air conditioning can help – to a point

Air conditioning can offset some of these effects.

For example, studies have found that having a working air conditioner means fewer people die, student learning isn’t compromised and extreme heat outside during pregnancy doesn’t hurt fetuses.

Not everyone has air conditioning, however, especially in normally cooler areas like Oregon, Washington and Canada that have experienced unusually extreme temperatures this year. And many people can’t afford to own or operate them. Survey data from 2017 found that around half of homes in the Pacific Northwest
lacked air conditioning. And about 42% of U.S. classrooms lack an air conditioner.

While heat waves are shown to induce more households to install air conditioning, it’s hardly a panacea. By 2100, higher use of air conditioning could increase residential energy consumption by 83% globally. If that energy comes from fossil fuels, it could end up amplifying the heat waves that caused the higher demand in the first place.

And in the U.S. South, where air conditioning is omnipresent, hotter-than-usual summers take the greatest toll on states’ economic growth.

In other words, as temperatures rise, economies will continue to suffer.

Statistics Canada says manufacturing sales up 1.4% in July at $71B

OTTAWA – Statistics Canada says manufacturing sales rose 1.4 per cent to $71 billion in July, helped by higher sales in the petroleum and coal and chemical product subsectors.

The increase followed a 1.7 per cent decrease in June.

The agency says sales in the petroleum and coal product subsector gained 6.7 per cent to total $8.6 billion in July as most refineries sold more, helped by higher prices and demand.

Chemical product sales rose 5.3 per cent to $5.6 billion in July, boosted by increased sales of pharmaceutical and medicine products.

Sales of wood products fell 4.8 per cent for the month to $2.9 billion, the lowest level since May 2023.

In constant dollar terms, overall manufacturing sales rose 0.9 per cent in July.

S&P/TSX gains almost 100 points, U.S. markets also higher ahead of rate decision

TORONTO – Strength in the base metal and technology sectors helped Canada’s main stock index gain almost 100 points on Friday, while U.S. stock markets climbed to their best week of the year.

“It’s been almost a complete opposite or retracement of what we saw last week,” said Philip Petursson, chief investment strategist at IG Wealth Management.

In New York, the Dow Jones industrial average was up 297.01 points at 41,393.78. The S&P 500 index was up 30.26 points at 5,626.02, while the Nasdaq composite was up 114.30 points at 17,683.98.

The S&P/TSX composite index closed up 93.51 points at 23,568.65.

While last week saw a “healthy” pullback on weaker economic data, this week investors appeared to be buying the dip and hoping the central bank “comes to the rescue,” said Petursson.

Next week, the U.S. Federal Reserve is widely expected to cut its key interest rate for the first time in several years after it significantly hiked it to fight inflation.

But the magnitude of that first cut has been the subject of debate, and the market appears split on whether the cut will be a quarter of a percentage point or a larger half-point reduction.

Petursson thinks it’s clear the smaller cut is coming. Economic data recently hasn’t been great, but it hasn’t been that bad either, he said — and inflation may have come down significantly, but it’s not defeated just yet.

“I think they’re going to be very steady,” he said, with one small cut at each of their three decisions scheduled for the rest of 2024, and more into 2025.

“I don’t think there’s a sense of urgency on the part of the Fed that they have to do something immediately.

A larger cut could also send the wrong message to the markets, added Petursson: that the Fed made a mistake in waiting this long to cut, or that it’s seeing concerning signs in the economy.

It would also be “counter to what they’ve signaled,” he said.

More important than the cut — other than the new tone it sets — will be what Fed chair Jerome Powell has to say, according to Petursson.

“That’s going to be more important than the size of the cut itself,” he said.

In Canada, where the central bank has already cut three times, Petursson expects two more before the year is through.

“Here, the labour situation is worse than what we see in the United States,” he said.

The Canadian dollar traded for 73.61 cents US compared with 73.58 cents US on Thursday.

The October crude oil contract was down 32 cents at US$68.65 per barrel and the October natural gas contract was down five cents at US$2.31 per mmBTU.

The December gold contract was up US$30.10 at US$2,610.70 an ounce and the December copper contract was up four cents US$4.24 a pound.
