A new paper reported here debunks an important feature of IPCC climate models: that the oceans absorb infrared radiation from greenhouse gases, thus heating the oceans and accounting for the “missing heat” predicted by climate models. No, they do not. The research, which appeared in the Proceedings of the National Academy of Sciences, identified several physical reasons that ocean warming from CO2 is all but impossible. From the link above:
“For all … of these physical reasons… ocean warming can only be related to solar activity and modulators of sunshine at the surface like clouds, and not increased far-IR radiation from increased greenhouse gases.
This is a death knell for conventional climate models, which falsely assume the opposite of the … physical reasons above, thus falsely claiming IR from greenhouse gases can heat the oceans (70% of Earth’s surface area) and where allegedly 90% of the ‘missing heat’ has gone.”
One of those physical reasons is related to whether water and water vapor act as “blackbodies,” which is assumed by climate models embodying AGW. They do not:
“The significance to the radiative ‘greenhouse effect’ is that the climate is less sensitive to both CO2 and water vapor since both are less ‘greenhouse-like’ emitters and absorbers of IR radiation as temperatures increase.”
So the oceans are not the massive AGW heat sinks that we hear about so often. And much of that “nasty” CO2 finds eager vegetative consumers: This article reports research suggesting that 90% of CO2 emissions are stimulating forest growth around the world:
“Even NASA’s own satellite data shows that the planet is steadily greening, by as much as 1.5 percent a year in northern latitudes. Yet in May last year, the world’s media mournfully reported that atmospheric CO2 had just passed the 400ppm mark for the first time in three to five million years, with NASA clamouring to paint the news in a calamitous light. …
Nova says ‘the northern Boreal forests are probably drawing down something like 2 – 5 gigatons of CO2 every year, and because the seasonal amplitude is getting larger each year, it suggests there is no sign of saturation. Those plants are not bored of extra CO2 yet. This fits with Craig Idso’s work on plant growth which demonstrates that the saturation point — where plants grow as fast as possible (and extra CO2 doesn’t help) is somewhere above 1000 and below 2000ppm. We have a long way to go.’”
I believe a greener world is preferable to a less green one. In fact, I believe a somewhat warmer world is preferable. That would bring many obvious benefits to mankind, not least of which is a reduction in weather-related misery and death. (No, severe weather is not an implication of a warner climate.) I therefore find it bizarre that so many have been successfully propagandized to believe that we should sacrifice vast amounts of resources to prevent AGW. It is not a danger of much significance. There are explanations for the propaganda, of course, but they will have to be the subject of another post.
