This would not be the article to use to support that claim though.
'As Ewing and Donn read the evidence, an Ice Age will result from a slow warming and rising of the ocean that is now taking place.'
What are you meaning by 'no longer a black box' in this context?
- reaperducer 7y agoWhat are you meaning by 'no longer a black box' in this context? Sorry, I mean "black body." We were taught that the Earth absorbs as much radiation as it emits. The term we were taught for that is "black body."
- greglindahl 7y agoThat’s not what a black body is - that’s a body in thermal equilibrium.
- reaperducer 7y agoThat’s not what a black body is - that’s a body in thermal equilibrium Wikipedia disagrees. "A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. (It does not only absorb radiation, but can also emit radiation. The name "black body" is given because it absorbs radiation in all frequencies, not because it only absorbs.)" https://en.wikipedia.org/wiki/Black_body https://en.wikipedia.org/wiki/Black_body
- inflatableDodo 7y ago>Wikipedia disagrees. It really doesn't. This might help. http://astronomy.swin.edu.au/cosmos/B/Blackbody+Radiation http://astronomy.swin.edu.au/cosmos/B/Blackbody+Radiation Note the line 'As the temperature of the blackbody increases, the peak wavelength decreases' Just because some things can be approximated for varying degrees of usefullness as absorbing and emitting equally well on all frequencies (which the earth is really bad at anyway), does not mean they are stable in temperature.
