These rising
atmospheric greenhouse gas concentrations have led to an increase in global
average temperatures of ~ 0.2 °C decade — 1, much of which has been absorbed by the oceans, whilst the oceanic uptake of
atmospheric CO2 has led to major changes in surface ocean pH (Levitus et al., 2000, 2005; Feely et al., 2008; Hoegh - Guldberg and Bruno, 2010; Mora et al., 2013; Roemmich et al., 2015).
The Gulf of Thailand changes from an
atmospheric CO2 sink during the boreal winter to a CO2 source in summer due to higher water

Because the
average surface
temperature of Mars is colder than -80 °F and the

The standard assumption has been that, while heat is transferred rapidly into a relatively thin, well - mixed surface layer of the ocean (
averaging about 70 m in depth), the transfer into the deeper waters is so slow that the
atmospheric temperature reaches effective equilibrium with the mixed layer in a decade or so.
By showing that (a) there are no common physical laws between the warming phenomenon in glass houses and the fictitious

temperature or rise above

It seems to me, in my lay understanding, that climate change is likely to be expressed as increased

The

atmospheric carbon dioxide are significantly correlated over the past thirty years.
A scientist would never focus on ONLY one variable, CO2, probably a very minor variable with no correlation with
average temperature, when there are dozens of variables affecting Earth's climate... and then further focus only on manmade CO2, for political reasons (only that 3 % of all
atmospheric CO2 can be blamed on humans... which is the goal of climate modelers... along with getting more government grants.)
I can't believe I am saying this, as the media covergae of climate change is almost universally appalling BUT I think part of the problem is that we, as the scientific community allowed the message / meme to permeate that media that «warming» was purely an
atmospheric temperature phenomena to be assessed solely by
average global
temperatures.
Because of the increase in CO2 concentrations in the atmosphere a higher
average temperature is maintained through simple
atmospheric radiative effects.
