Can we get 45 Cm of snow tonight and tomorrow

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

wo

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

global

its not real never was its a government money grab

Global Warming

Doesn't mean it's going to be warm, it means weather patterns have been/are being changed as a result of this...so cold/colder or warm/warmer than normal; more disaster weather conditions, more forest fires, etc.

Weather

Global warming is a lie, we are in a mini ice age.

Where's the snow!

Would like to snowmoble. There is some in Muskoka Lakes region, but most is hard packed. It would be nice to have WEST WINDS blowing off Georgian Bay instead of North West.

Lack of Winter weather

I was hoping the winter weather (complete with snow) would arrive in southern Ontario in the new year (2019). So far the weather is a bit colder but there is no snow. We need a cold snap, with a winter snow storm because if this does not happen, bug season in southern Ontario will be awful this spring. So every day I do a snow dance on my balcony, and I pray the the weather Gods. A little help from the old Farmer's Almanac would be nice as your forecast has totally missed the mark. I am going to pull out my last desperate act, I am washing and waxing my car tomorrow. Help......Don

Cold snap

Looks like your charm worked
