Toronto Winter

Most snow accumulation since 1968, February being the worst month. Good old fashion winter--just as I remember from the 60's/70's growing up in Bradford, Ontario. We use to get severe ice storms back then as well.

Bad bad bad

So basically were going to have an awful year of weather. Time to gtfo.

Worse Weather 2019

The weather this year of 2019 has been very intensely intense. With every snow storm then afterwards turns into a freaking Ice Storm and Wind Storm almost like a Tornado in Toronto Canada. Temperatures are like going from Summer like Temperatures to like deep Winter Temperatures like Siberia, Russia Temperatures.

August 2019

Getting married in August in Newcastle, ON. Predictions for the weather? I know we’re expecting cooler and rainer temps but just wondering if anyone had further insight.

Global warming

So much for Global Warming, guess it misses Canada this year.

NO - this is because of global warming

Please, don't confuse weather with climate, global warming is an overall warming of our climate, just because today was cold that doesn't mean global warming isn't real -- that's like saying because you had breakfast today world hunger isn't real


you need to check the data sets, i too fell for it because i didn t look at the data myself and only took what was given as info.... look at the sun cycle and temp data sets yourself.... it took me a long time to actually look..... and less than five min to be shocked at how easily i had been brainwashed while thinking i was one of the informed. ask yourself when did plant food become satan? does it make any sense that where 99.9 percent of a systems energy is introduced from is considered to have little to no impact in describing that system, yet what represents 0.3 percent has the largest impact.... even a larger role presently though is a smaller percent then previously represented ? and the most obvious question possibly...... is it often hotter out on a cloudy day or sunny? i hope this nudges you towards checking it out even only five min my friend
