roach has no idea about AGW. That CO2 is a greenhouse gas has been known since about 1850. Arrhenius added to this late in the 1800s and refined his work in 1906.

I have shown that the amount of IR reaching space from the surface of the earth is decreasing as GHG concentrations rise.


See how there is less IR reaching the satellite at the various bands representing the GHGs over time as the GHGs increase in concentration.

A study of IR reaching the surface, that is IR that left the surface but, by absorption and re-emission from GHG molecules, is sent back to the surface.



Less heat can escape, the inevitable result is the world is heating up. BTW roach, that graph is not temperature but IR radiation redirected back to the surface by CO2.

We are talking about the mechanism (see the second post in the locked thread in Relationships) not correlation implies causation.

But roach can’t let himself know this.

Doesn't feel like winter here.

Nights are cool  BUT 29 C..  28 C almost everyday this August ..gawd..even in July!!

Some places in Australia are expecting 13C above average tomorrow, (today)  and next week we're going to have 30C.
This is still WINTER.

Think my air-con is going to get a real work out this summer. It is already drying out here. Glad I don't live in Southern states.

If there was a blip of cold Booby, it sure isn't happening here.  WISH IT WAS.

Monkey boy...  here I was thinking you ignore me...  why the need to lie about me all the time?

Been caught out again have you.

Thanks for proving me right about you once again.

Same old crap posted time and time again answering your own strawmen and never once addressing a real post with real science or any insight.

Arctic sea ice extent same as 2006.

Full series -



Maybe even 2004.

LOL Greenland

The Greenland Ice Sheet has put on 500Gt this year.

Ps.  Ice melt has a tendency to refreeze.

"Re-calibration of Arctic sea ice extent datasets using Arctic surface air temperature records

Abstract
A new seasonal and annual dataset describing Arctic sea ice extents for 1901-2015  was  constructed  by  individually  re-calibrating sea  ice  data  sources  from the three Arctic regions (North  American,  Nordic  and  Siberian)  using  the  corresponding surface air temperature trends for the pre-satellite era (1901-1978), so  that  the  strong  relationship  between  seasonal  sea  ice  extent  and  surface  air  temperature  which  has  been  observed  for  the  satellite  era (1979-present)  also  applies to the pre-satellite era. According to this new dataset, the recent period of Arctic  sea  ice  retreat  since  the  1970s  followed  a  period  of  sea  ice  growth  since the mid-1940s, which in turn followed a period of sea ice retreat since the 1910s. Arctic sea ice is a  key  component  of the Arctic hydrological cycle both through its freshwater   storage role,   and   its   influence on oceanic and atmospheric circulation. Therefore, these new insights have significance for our understanding of Arctic hydrology."

The scare story about the Arctic is Bovine Scat.

The Arctic is a dynamic piece of globe. It shouldn't be looked at in isolation.
