No it hasn't, but in any case, global warming doesn't mean we won't still have winter.

You can't disprove any of the facts I listed, can you?

[jt004c]

Yes, global warming can make winter worse.

I remember when they said becuz i live in denmark. They said that near christmas there wouldn't come snow. But snow came and it was snowing for like 3 months! And also in january it was snowing in england!

There are short-time temperature fluctuations, what you can see through all existing record. But global temps are increasing, constantly going up.

Last decade is warmest on record and 2009 is warmest on record.

[JAROSLAVAGINA]

actually, it was predicted that global temps (a.k.a. world wide) would be increasing constantly due to increasing co2 levels. and that the recent drop off in global temps over this decade do not match the climate models.

do you disagree with this statement?

[starrdreams]

Different sources of information about global climate shows that climate is changing and temperature is rising.

Yes, capital was shut down. Because of alot of snow. As it was predicted - this is one of the consequences of climate change.

9/11, climate change, Obama.....when are people going to stop trusting the damn media??? Don't buy into every TRICK you see on TV. And don't turn your cheek to what you DON'T see on TV.

Great video!

[JAROSLAVAGINA]

so if we had a weather station in Vancouver and a weather station here in texas what would the statistical mean average show for global temps? no change?

Fair enough, texas isn't the center of the world. how about the north eastern portion of the united states? wasn't the capital shut down?

as you posted earlier this winter is "just a weather variable". does that hold true for canada as well?

[JAROSLAVAGINA]

you are correct actually. climate change is all of the time. further proof that "climate change" is not man made.

your going to have to do better than that if you want to keep this debate going.

@JAROSLAVAGINA Yea, Texas is the center of the world... Why do not mention Vancouver, with "Record warm temperatures and heavy rains". "Research gathered over a 50-year period showed that the snow season in winters in B.C. are getting shorter by between four and five weeks, with warmer temperatures overall". (January 29, 2010 CBC, "Climate change blamed for Olympic snow shortage")

Or that this January was "warmest January in the 32-year satellite-based data record".

Etc.
