Revisiting the ice core isotope thermometer

André Bijkerk Isotopes in precipitation are essentially not a proxy for temperature but for humidity. Category: Paleoclimatology and Atmosphere This is the fourth post in series with the objective of revisiting the Pleistocene ice ages, demonstrating that several well-accepted scientific practices don't hold up very well in the big picture. In the previous [...]

The Younger Dryas and the isotope paleothermometer

Researching discrepancies of the Arctic isotope paleothermometer versus other climate reconstructions during the Younger Dryas. Category: Paleoclimate This is the second post in series with the objective of revisiting the Pleistocene ice ages, demonstrating that several well-accepted scientific practices don't hold up very well in the big picture. We will examine possible flaws in current [...]

The African Humid Period

André Bijkerk As we in the north of the globe wonder about climate changes in the past, we think about ice ages, the equatorials however wonder about climate change as in monsoons changes. For instance if we zoom in on the Sahara in Google Earth we see remains of lush rainforests and numerous [...]

The mystery interval

Category: Paleoclimatology Sub category: the isotope thermometer of the ice cores. André Bijkerk Abstract The Anthropogenic climate change hypothesis has its roots in the climate reconstructions based on the ice core records of Antarctica and Greenland. Isotope ratios of oxygen and hydrogen in the ice are assumed to be proxies for global temperature. [...]
