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 posts we have concluded that the isotope paleo thermometer of [...]
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 mainstream theories. One of those is the isotope thermometer of the [...]
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 rivers in various shades of tan, leaving no doubt that [...]
The physics of doubling CO2 (Summary)
Summary of a draft Research Article - Category: Atmosphere - Guest contribution of Frans van den Beemt - Physics of CO2 absorption processes: an original upper limit calculation of infrared CO2 absorption in case of a doubling of CO2 in the earth atmosphere Frans van den Beemt Abstract We analyzed CO2 absorption and emission of infrared radiation and calculated the upper limit of a possible temperature [...]
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 part of or nearly all of a perhaps 60+ ºC [...]
