THE source of news about science and the environment as they relate to the Hawaiian Islands, hosted by veteran science reporter Jan TenBruggencate. Issues covered include archaeology, astronomy, botany, climate science, conservation, efficient transportation, geology, marine sciences, sustainability and zoology, with occasional forays into other areas, including traditional navigation and canoe voyaging.

Raising Islands.
I borrow the name of this blog, gratefully and with permission, from my friend Nainoa Thompson. He uses the term “raising islands out of the sea” to create in the mind the experience of a voyaging canoe coming up on a distant shore, and of watching distant peaks rise out of the sea as the canoe approaches.
The first time I did it with him, our vehicle was the voyaging canoe Hokule'a and the island was Nihoa. I recall the crew's thrill at dawn, seeing the twin peaks of the island appear, and then the saddle between them, and finally the whole island. Thompson was the non-instrument navigator who had brought us there using only stars, clouds, wind, seas, birds and other cues.
The name of this blog also invokes the idea of responsibility—raising as lifting up, as caring for and conserving.
The key to responsibility is understanding. If we are to care for these islands, we need the kind of understanding of the environment that a traditional navigator needs.

Discovering that CO2 change and therefore human activity does not cause global warming is a start. But this leaves the question of what actually does drive average global temperature change.
Two primary drivers of average global temperature have been identified. They very accurately explain the reported up and down measurements since before 1900 with R2>0.9 (correlation coefficient = 0.95) and provide credible estimates back to the low temperatures of the Little Ice Age (1610).
The influence of CO2 change is insignificant.
Coefficient of determination, R2 = 0.9049 considering only sunspots and ocean cycles.
R2 = 0.9061 considering sunspots, ocean cycles and CO2 change.
The calculations use data since before 1900 which are publicly available.
The coefficients of determination are a measure of how accurately the calculated average global temperatures compare with measured.
Everything not explicitly considered (such as the 0.09 K s.d. random uncertainty in reported annual measured temperature anomalies, aerosols, CO2, other non-condensing ghg, volcanoes, ice change, etc.) must find room in the unexplained 9.51%.
The tiny difference in R2, whether considering CO2 or not, demonstrates that CO2 change has no significant effect on climate.

Thanks for your comment. There are, of course, numerous issues of logic with this statement, starting with sloppy language in the first sentence. The sunspot correlation cited in the link has long ago been debunked. Sunspot and activity tracked each other for a time, but in 1980, solar activity declined significantly while temperatures continued to rise. I'd be pleased to see compelling data, but remain unconvinced of this proposal based on what has been provided.
Solar cycle amplitude or duration considered separately don't work but the combination of the two, which is what the time-integral does, is what works (actually the time-integral of the sunspot number anomaly). It has never been debunked.
The 'compelling data' is made public at the link and references.N2 822
Thanks, Dan, for your comments. I think we can end this conversation now. Solar forcing clearly shows some climate correlation. However, your assertion that CO2 change is insignificant flies in the face of overwhelming data to the contrary.
