About Andre Bijkerk

About André Bijkamp (Chief Editor) - Andre K. Bijkerk was born in Heerde in 1953. He studied at the Royal Military Academy in Breda (specialty: Electronics and control technology), before becoming a fighter pilot in Canada. He attained a career with the Royal Netherlands Air Force at various airbases, the airforce staff and NATO staffs in Germany. His interest in climatology was awakened with the discovery of a mammoth mummy in North Siberia in 1998 which triggered several questions about the climate during the ice age.

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 [...]

Heating the natural greenhouse

Kees Le Pair Guest contribution by Kees le Pair - Category: Atmosphere Abstract The gap between measured temperatures and the radiation equilibrium is more than 33 ºC as assumed in present day greenhouse considerations. Either the atmospheric greenhouse is not understood well enough, or rather there may be other mechanisms that help to bridge [...]

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. [...]
