"How many times do you have to be told the data shows warming precedes the accumulation of CO2 and cooling causes it to dissipate?"
One single small track mind. A mantra duh...temps precede CO2 duh.....temps precede co2 duh. No understanding that CO2 is now and has in the past lead temps higher because it is a greenhouse gas. There is synergy between temps and CO2. Do you know that word? You guys are amusing.
Futurecunt must be losing his cool along with losing the argument. Liberals love their name calling and vulgar comments when they know they are wrong but won't admit it.
How is this... using data show CO2 accumulation has caused warming in the past. Show some sort of (CO2 buildup) cause then effect (warming) relationship. I am not interested in declarative statements, I am interested in data. If you have no such data... then say so. After that we can talk about guesses and theories.
I can't be bothered with him. He is so wrong that it is difficult to know where to begin. All he has done since his first post is assert nonsense with an air of certitude and then hurl a few insults. There isn't really anything there to engage.
I've put him on ignore, too. But others keep quoting him compelling me to comment on the silliness. I should restrain myself but his ignorance bothers me.
This study is new but...... Global warming preceded by increasing carbon dioxide concentrations during the last deglaciation Jeremy D. Shakun, Peter U. Clark, Feng He, Shaun A. Marcott, Alan C. Mix, Zhengyu Liu, Bette Otto-Bliesner, Andreas Schmittner & Edouard Bard AffiliationsContributionsCorresponding author Nature 484, 49â54 (05 April 2012) doi:10.1038/nature10915 Received 16 September 2011 Accepted 01 February 2012 Published online 04 April 2012 The covariation of carbon dioxide (CO2) concentration and temperature in Antarctic ice-core records suggests a close link between CO2 and climate during the Pleistocene ice ages. The role and relative importance of CO2 in producing these climate changes remains unclear, however, in part because the ice-core deuterium record reflects local rather than global temperature. Here we construct a record of global surface temperature from 80 proxy records and show that temperature is correlated with and generally lags CO2 during the last (that is, the most recent) deglaciation. Differences between the respective temperature changes of the Northern Hemisphere and Southern Hemisphere parallel variations in the strength of the Atlantic meridional overturning circulation recorded in marine sediments. These observations, together with transient global climate model simulations, support the conclusion that an antiphased hemispheric temperature response to ocean circulation changes superimposed on globally in-phase warming driven by increasing CO2 concentrations is an explanation for much of the temperature change at the end of the most recent ice age.
That's fine but how does that bolster your claim mankind is responsible for the measured effects? Surely you are not claiming industrial production and the burning of fossil fuels is responsible for the time period discussed.
