A short piece in Science (AAAS) by Kelly Servick (Mar 6, 2017) ignores carbon dioxide in explaining how increased sunlight has caused U.S. corn yields to grow over the past 3 decades. Servick says the increased sunlight was due to decreased atmospheric aerosol content and that projections by global climate models indicate that this will not continue into the future due to rising temperatures and drought. Interestingly, the positive effects of carbon dioxide on plant drought tolerance and fertilizing effect were not mentioned.
There is quite a story, a back story, really, concerning the Tom Karl paper in 2015 in which he concluded that there never was a pause in global warming because they needed to adjust the Sea Surface Temper-atures upward to make other measurements comport to (or with) the ship turbine inlet temps.

Bob Endlich describes growing up around barrier beaches and how they were changed after every strong storm that went through the area. He also provides information from news accounts during that period of time. Climate alarmists frequently use barrier beaches to show how global warming has changed the environment, but, in fact, these sandbars and sandy shorelines have always moved around in the wind and waves due to the natural effects of the weather.

“Audubon’s equivocal policy on wind power ostensibly calls on wind energy developers to consider planning, siting, and operating wind farms in a manner that avoids bird carnage and supports ‘strong enforcement’ of laws protecting birds and wildlife. On the other hand, the same Audubon policy speaks about ‘species extinctions and other catastrophic effects of climate change’ and ‘pollution from fossil fuels’.”
The cover of the January-February 2016 issue of Audubon Magazine proclaims: Arctic on the Edge: As global warming opens our most critical bird habitat, the world is closing in. In reality, it is the magazine’s writers and editors who have gone over the edge with their misleading reports on the Arctic.
This magazine is so awash in misstatements of fact and plain ignorance of history, science, and culture, that Continue reading “Audubon Goes over the Edge (Jan/Feb 2016 issue) promotes anti-science alarmism)”

In science, one likes to have more examples than theories. – Dusan Djuric
Those words, spoken whimsically about cosmology, apply to climate science as well. The theory of the sensitivity of climate to the radiative forcing imposed by a doubling of carbon dioxide suffers from a lack of observed, repeatable examples. Paleo-climate studies carry with them the uncertainty of the proxy data and unmeasured assumptions on which they are based. Studies regarding the forcing from volcanoes and other transient events may not be repeatable for some time. However, Lindzen et. al. 1995 (link ) and Ramanathan and Inamdar in Frontiers of Climate Modeling, 2006 (link ) each have pointed out that the seasonal variation of earth temperature is quite large and possibly a surrogate for climate change. With this in mind, I set out to determine how the seasonal variation Continue reading “Seasonal Radiative Response”
