Mike Duffy claiming old expenses again, but the blame falls on Liberal govt

The next few days in Toronto are going to feel hotter than Cairo and more sweat-inducing than Kabul, Afghanistans capital. Athens will feel like a breezy spring day. Toronto is waking up to a muggy heat wave thats set to last until Saturday, with temperatures in the low 30s. Already this summer, the scorching temperatures have prompted 11 heat alerts and four extreme heat alerts, according to the citys medical officer of health.

Environment Canada is calling this next one the most significant heat wave of the summer.

The temperatures arent particularly bad by historical standards, said David Phillips, senior climatologist at Environment Canada. Instead, its the humidity that makes it feel so much worse. You can cut [the air], he said. Its [hot] morning, noon and night. The next three days will feel warmer than 40 C, thanks to humidity.

Suffering Torontonians can take heart knowing they are not alone. Bangkok is wading through a swampy 34 degrees that feels like 41, while Havana feels like 40. And although Dubai sits at 41, it feel likes a blazing 52 for residents venturing outside.

One of the culprits behind Torontos latest heat wave? Perspiring corn.

Believe it or not, crops sweat, Mr. Phillips said. Air streams move north and as they travel, they gather the moisture released from plants such as corn and soybeans. This sweating is part of the natural process of evapotranspiration when moisture is drawn from the soil and released by plants into the air, increasing humidity.

While its been humid in Toronto, to date there have been 26 days with temperatures above 30 degrees. By this time last year, there had been only nine, Mr. Phillips said. By the end of the week, he believes the city will have have reached 31 days breaching 30 degrees.

And theres been little relief in the form of rain. Tuesday marked the driest period from May 1 to Aug. 9 over the last 79 years in Toronto. Just 107 millimetres of rain fell this year over that period, 44 per cent of normal rainfall.

In some of those other dry years, it wasnt as hot, so what you see is youve got like a double whammy youve got the heat and youve got the dryness, Mr. Phillips said.

For those without air conditioning, the city has seven official cooling centres and is extending hours for indoor and outdoor public pools to help residents cool off.

But other than escaping to an air-conditioned room or lounging by the pool, there arent many options for residents when humidity is involved. Unlike other countries that have adapted hundreds of years of suffering into their architecture and habits, Canada is still learning.

Over generations, Iranian architects perfected the design of their structures to be naturally cool in the summer heat, expertly directing and deflecting air currents to create a pleasant temperature.

In Turkey, drinking hot tea is thought to cool a person down a counter-intuitive endeavour, but effective nonetheless. The University of Ottawas Thermal Ergonomics Laboratory confirmed in a study that drinking a hot beverage could cool down the body, but with caveats: Under conditions permitting full sweat evaporation, body heat storage is lower with warm water ingestion. This only works in arid places and allows for full evaporation of sweat, the researchers say.

This summer may be hot, but Toronto has survived worse.

In July, 1936, the worst heat wave ever recorded struck the heart of the American Midwest, slowly creeping north to Ontario, without a modern air conditioner in sight.

When it reached Toronto, it sent temperatures to 40.6 degrees for three straight days. The death toll was 225, says Heritage Toronto, the highest number linked to a specific event since the flu pandemic in 1918. And in an indication of just how bad it was, on July 12, the city allowed the Lords Day Act which prohibited commerce on a Sunday to be lifted, clearing the way for ice sales.

Canada has a complicated relationship with the summer as a winter country, it hasnt yet figured out how to make sense of the heat.

Its this puritan theological meteorology that exists. People think, Oh were owed this or Oh boy, are we going to pay for this. This is going to be the winter from hell, because we had such a warm summer, Mr. Phillips said. Nope.

Residents are instead left to the vagaries of weather, although with unrelenting heat this summer, the city will probably start believing its finally owed something.
