The reason why the Earth is getting warmer is because of an increase solar activity. Just go on spaceweather.com and you'll see the increase of solar flares during the past 10 years.
Even if it wasn't a myth... Kyoto protocol goes agaisnt Canada's national interests.

With about 8 seconds of Googling:
"Aside from the fact that solar effects cannot physically explain the recent global warming, as with GCRs, there are several empirical observations which solar warming could not account for. For example, if global warming were due to increased solar output, we would expect to see all layers of the atmosphere warm, and more warming during the day when the surface is bombarded with solar radiation than at night. Instead we observe a cooling of the upper atmosphere and greater warming at night, which are fingerprints of the increased greenhouse effect."
From some "Huber and Knutti study":
Since 1950, the volcanic forcing has been negative due to a few significant eruptions, and has offset the modestly positive solar forcing, such that the net natural external forcing contribution to global warming over the past 50 years is approximately zero (more specifically, the authors estimate the natural forcing contribution since 1950 at -10 to +13%, with a most likely value of 1%).
Their words: "Even for a reconstruction with high variability in total irradiance, solar forcing contributed only about 0.07°C (0.03-0.13°C) to the warming since 1950."

I haven't verified this data or anything but if anything is a myth it seems like this whole sunflare idea is.
EDIT: This is the article:
http://www.nature.com/ngeo/journal/v.../ngeo1327.html
From the abstract: We find that since the mid-twentieth century, greenhouse gases contributed 0.85 °C of warming (5–95% uncertainty: 0.6–1.1 °C), about half of which was offset by the cooling effects of aerosols, with a total observed change in global temperature of about 0.56 °C.
Our method is complementary to optimal fingerprinting attribution and produces fully consistent results, thus suggesting an even higher confidence that human-induced causes dominate the observed warming.
It's in ****ing Nature, and you're telling me these researchers are wrong and you're right by using "spaceweather.com " as your only argument?
