Westmount Greenhouse

Westmount’s greenhouse has a cosy warmth even on the coldest winter day.  As greenhouses go, it surely does not compete with the likes of our Montreal Botanical Gardens, but it is definitely one of the prettiest and it has benches scattered about amongst the plants and flowers that encourage visitors to sit for a spell, whether to read or to contemplate the beauty surrounding them.  My favourite is the connecting room with the koi pond which has benches on either side of the pond.  The greenhouse has been closed throughout 2017 for repairs and restoration.

Blustery cold day with wet snow and rain.  Officially, it’s the first snow but not much of it is sticking to the ground so there is not that much in the way of accumulation.  I can also confirm I have zero desire to be out there with my camera.  Zero clicks given.

Observing the Ozone Hole from Space: A Science Success Story

Using our unique ability to view Earth from space, we are working together with NOAA to monitor an emerging success story – the shrinking ozone hole over Antarctica.

Thirty years ago, the nations of the world agreed to the landmark ‘Montreal Protocol on Substances that Deplete the Ozone Layer.’ The Protocol limited the release of ozone-depleting chlorofluorocarbons (CFCs) into the atmosphere.

Since the 1960s our scientists have worked with NOAA researchers to study the ozone layer. 

We use a combination of satellite, aircraft and balloon measurements of the atmosphere.

The ozone layer acts like a sunscreen for Earth, blocking harmful ultraviolet, or UV, rays emitted by the Sun.

In 1985, scientists first reported a hole forming in the ozone layer over Antarctica. It formed over Antarctica because the Earth’s atmospheric circulation traps air over Antarctica.  This air contains chlorine released from the CFCs and thus it rapidly depletes the ozone.

Because colder temperatures speed up the process of CFCs breaking up and releasing chlorine more quickly, the ozone hole fluctuates with temperature. The hole shrinks during the warmer summer months and grows larger during the southern winter. In September 2006, the ozone hole reached a record large extent.

But things have been improving in the 30 years since the Montreal Protocol. Thanks to the agreement, the concentration of CFCs in the atmosphere has been decreasing, and the ozone hole maximum has been smaller since 2006’s record.

That being said, the ozone hole still exists and fluctuates depending on temperature because CFCs have very long lifetimes. So, they still exist in our atmosphere and continue to deplete the ozone layer.

To get a view of what the ozone hole would have looked like if the world had not come to the agreement to limit CFCs, our scientists developed computer models. These show that by 2065, much of Earth would have had almost no ozone layer at all.

Luckily, the Montreal Protocol exists, and we’ve managed to save our protective ozone layer. Looking into the future, our scientists project that by 2065, the ozone hole will have returned to the same size it was thirty years ago.

People Covered Their Faces And Showed Up To Bus Stops In Montreal To Protest Bill 62
The new law forces people to uncover their faces to receive government services — including taking the bus.
By Ishmael N. Daro

The law requires people to uncover their faces while receiving any government services — including taking a bus.

Although no religious group or religious garment is mentioned explicitly in the legislation, the main target appears to be Muslim women who wear a niqab or burqa.

Dozens of people showed up to bus stops on Friday with their faces covered.
