Fallacies of Global Warming

Human caused global warming is the present paradigm in the environmental scientific community, though officially the term "climate change" as this is considered the more comprehensive term However, it is quite well that implied consensus is in the warming direction, hence what is meant by the term.Show more

Climate change is a matter of fact and certainty, and has been happening on this planet for millions upon millions of years. The idea that humans are causing the recent warming through due to burning of carbon-based fuels is much more contentious and not consistent with the Paleoclimate / Historical records.

Key points covered in this cast:
(1) There is no clear and consistent correlation between temperature and carbon dioxide from proxy data in the deep-time, geologic, paleoclimate record.
(2) There is a correlation in the glacial-interglacial ice core cord spanning roughly a half a million years (500,000 yrs). Yet importantly, carbon dioxide lags behind temperature (not the other way around) suggesting another mechanism is driving glacial-interglacial cycles, and carbon dioxide is simply responding.
(3) In the most recent interglacial (Holocene) period, approximately the last 10,000 years, present temperature are unremarkable, and below the overall average of the whole period, based on available temperature estimates from proxy data.
(4) Finally, recent historical records (Central England) show no anomalous temperature increases above the overall historical trend since the 1600s. Furthermore, there is no coincident change or substantial increase in temperature occurring at the onset of industrialization from increased carbon-based fuel burning in the mid-to-late 19th century.

Hence, the Paleoclimate record (temperature and carbon dioxide) as it is - does not support the hypothesis of substantial or alarming warming caused by emissions of carbon dioxide from human activity. The historical, glacial and geologic timeframes all show present warming well within natural variability. Given the Paleoclimate record, model-based alarmist global warming narratives should be further challenged, and at present, there is little justification for draconian decarbonization of the overall energy economy.
