Cover the poles and all other ice with black carbon, burn more fuel, release more methane, reduce the reflectivity of surfaces. To start. But it isn't a mini ice age happening again. There's no evidence of this at all.

Well, Walter, this hypothesis has lost favour with all but the most ardent solar folk. If Svensmark is correct, then the temperature and magnetic index should be tracking in the same direction, with a slight offset (very slight). Does the temperature follow the lead from solar magnetic...

The golf ball on North mountain.

My home town is not too far from Shag Harbour. I'll let you in on a secret DB, a marine engineer makes those parts in his basement. There's always a dupe willing to believe it's the real stuff. ( the real stuff is in a bunker) lol

Which is true. You say so yourself below. Like I said, a common tactic of yours. You called us benign in comparison, right before you caught my comment to Anna. No strawman, it's from your own words, and the many other times you've said likewise. Another such example is when we've...

From Pharyngula: Maybe they fear the kinds of backlash that the Danish cartoonists and others have received from scrutinizing Islam?

We? You live in any of those places? I hear in Australia, they're experiencing the opposite, record heat. Roy Spencer reported that December 2009 anomaly comes in at 0.28°C above the long-term average.

Extra-This is a common tactic of yours. Create a false position, attribute it to me and then argue against it, claiming thereby to have defeated my position. You are the master of the strawman. What I said: It's a common tactic of his. Nature has done worse than us before, so the claims of harm...

No you aren't. You wouldn't say such things as needing a millennium to establish a significant trend if you did. You probably don't even know how significance is determined. If you do, why don't you explain it to us all, and show us why you need 1000 years. No it doesn't. First of all, due to...

The only thing that separates poisons from non-poisons is dosage Walt. Carbon dioxide has been found to cause disruption, in the climate system, and is upsetting ocean chemistry. Burning fossil fuels creates other greenhouse gases as well, like nitrous oxide, which contributes to lower...

I read a great article in the Grey Lady today, the last in a five part series of articles on genetically modified cropping systems. The article centers around two people that at a glance should be rivals, an organic farming instructor and a molecular geneticist who has been modifying rice...

Yup. Non-sequitur. You're right of course. Even one species is too much.

It's a common tactic of his. Nature has done worse than us before, so the claims of harm due to our actions must be trumped up, incorrect, etc.

I am paying attention. You just seem to be woefully ignorant about what significant means. At about 15 years, the signal is evident. The noise is no longer dwarfing the signal. That is when you can statistically derive a trend which is significant. You don't need a millennium to establish a...

And from 2008 to the end of 2009, there has been a rise of about 0.7° (MSU-UAH), see: Two years, ten years, still not significant trends. I wonder what the talking points will be next year when all data sets of surface temperature, and lower troposphere temperature show new records for...

This weather is cold, yeah. It's something the meteorologists refer to as winter. You may have heard of it. No answer for my question above? Did you read about the CO2 fraction on Watts' blog?

ScienceDaily has updated the title of the article that Walt excerpted. It now reads: No Rise of Airborne Fraction of Carbon Dioxide in Past 150 Years, New Research Finds. Instead of: No Rise of Atmospheric Carbon Dioxide Fraction in Past 160 Years, New Research Finds If you actually read...

Airborne fraction isn't changing, still about 45% of the emissions stay airborne. That doesn't mean there hasn't been a rise in atmospheric concentration, or that there is no forcing imposed on the climate system. Not sure how that is a death knell for AGW. Care to explain Walt?

More importantly, no statistically significant cooling. This is a statistical trick. The reason that climate is defined as 30 years of weather, is because at that time frame it is highly unlikely that any significant trend could be due to noise. If you understand even basic statistics, this...
