The sun’s radiation comes to us in many forms, some of which are harmful to organic life while others are completely harmless or even essential, Daniel Bezte writes.

Prairie weather all starts with the sun
Weather takes energy, and the source of that is the star we all orbit around
Meteorology 101: Insolation, scattering and refraction
Also: La Niña comes to an end
Before we dive into our next meteorology 101 class, there has been some breaking weather news. Well, by the time you read this, the news might not be so breaking but, according to the U.S. National Oceanic and Atmospheric Administration, after three years and one of the longest La Niñas on record, ocean temperatures across
Not all weather folklore consistently pans out
SAYINGS | Prevailing weather adages usually cover the short-term outlook, and for good reason
Over the last month or so I have crisscrossed this great country of ours. I started in early July heading east into the Muskoka region of Ontario to compete in an Ironman 70.3 triathlon. After spending a couple of weeks there, I returned home and did some quick gardening before heading west to Canmore, Alta.
Weather school: Insolation and the solar constant
Equatorial regions get about 2.5 times more incoming solar energy than polar regions
In my last article, we gently stuck our toes into the idea of going back to school with our first weather school class. In that class we discussed how the sun creates energy and then how that energy travels from the sun to Earth. Today we will start to look at how that energy is
Weather school: Let’s start with the basics
The majority of the radiation we get from the sun comes in the form of visible light
At this time of the year, unless the weather is particularly bad, there are not a lot of “new” weather topics to discuss. We still have a month or two of winter left, and a lot can happen in that time that will affect our spring. I’ve spent more than enough time looking at long-range
Coleus for the sun
Coleus have long been an important component of shade plantings; whether planted in the ground or grown in containers, they have traditionally been popular plants for those spots in the garden that receive little direct sun. The older varieties, such as the “Rainbow” series, are all suitable for use in the shade and in fact,
Weaker sun will not delay global warming
London/ Reuters / A weaker sun over the next 90 years is not likely to significantly delay a rise in global temperature caused by greenhouse gases, a report said Jan. 23. The study, by Britain’s Meteorological Office and the University of Reading, found that the sun’s output would decrease up until 2100 but this would
Sun’s magnetic field could jinx GPS
Don’t blame the manufacturers — or even the gremlins — if your GPS system goes a little wonky in 2012. It’s likely solar flares will wreak havoc with at least some systems this coming year as the sun flips its magnetic field, says Pam Wilson, a precision agriculture instructor with Assiniboine Community College. “Basically the sun’s
Solar Dimming Can Trigger Freezing Winters
Acyclical drop in the sun s radiation can trigger unusually cold winters in parts of North America and Europe, scientists say, a finding that could improve long-range forecasts and help countries prepare for blizzards. Scientists have known for a long time that the sun has an 11-year cycle during which radiation measured by sunspots on
In Brief… – for Aug. 25, 2011
Correction:Due to an editing mistake, an opinion piece from Lydia Johnson which appeared in the Aug. 11 issue, contains the erroneous statement: “They did this fully knowing that they were going to ‘stuff’ this water into the already overcapacitated Lake Manitoba, which does have a proper outlet drain for the extra diverted waters to go
