The Anthropogenic Climate Change Thread

Recommended Posts

A little light reading for you,

In Greenland, rapid warming - approximately 7°C in a few decades - was observed around 11,500 years ago (Dansgaard et al., 1989; Johnsen et al., 1992; Grootes et al., 1993). Alley et al. (1993) also report evidence of even more rapid shifts in precipitation patterns, and other authors have noted swift changes in atmospheric circulation (Taylor et al., 1993; Mayewski et al., 1993).  Sea surface temperature changes of around 5°C, associated with sudden changes in oceanic circulation, also occurred in a few decades in the Norwegian Sea (Lehman and Keigwin, 1992).  Similar warming following the latest deglaciation occurred in regions of the Southern Hemisphere, though the warming there was less abrupt (Suggate, 1990; Denton and Hendy, 1994; Salinger, 1994; Jouzel et al., 1995).

This is climate glacial - interglacial, the scale is about 100,000 years, everything else is just noise, so excuse me if I don't sound the alarm bells. 

Interesting- if you take what you posted relating temperature and compare it to this graph of CO2...

... If you correlate those peaks of temperatue (2 - 2.75 C) add in that last peak and we might be looking at... what 4-7 degress? Maybe you should sound those alarm bells.

sigh.....CO2 is logarithmic, after the first doubling, the effects are virtually negligible due to the increased radiance of the earth. In fact, you get about 70% of the warming out of the first 40% of doubling CO2. You would need close 1200 ppm of CO2 to generate 7.4 W/mm for another 1C in temperature which would take you about 500 years to reach.

Like I said, nothing to see here.

sigh.....all previous interglacial periods had a mean average temperature of 2+ C above the running average, how do you expect to change this current one? 

Thanks for your views on this. Keep up the great work.

That is really interesting- I would love to see the moath on this- could you please point me in the right direction of your support?

Why not answer the question?

I wonder what he is going to find. 

Another fox guarding hen house Trump appointment.

Wait till he's gone and people are no longer afraid to speak.

Environmental concerns are non existent at the present time in the US federal government
