SCC Volume 3.1. Several articles have been published in this journal purporting to show that the well-documented rise in atmospheric CO2 is a natural phenomenon rather than human caused. His note reviews the overwhelming case that human activities are the…
SCC Volume 3.1. This paper addresses several issues concerning Milankovitch Theory and its relationship to paleoclimate data over the last 800,000 years. The approach taken treats the insolation as it is physically, a time-dependent wave. A parameter free model, based…
SCC Volume 2.3. Present day treatises dealing with weather and climate often use seemingly physical quantities, while they are in fact averages of such. Inserting these into formulas is physically not permitted. It leads to an assumption of the magnitude…
SCC Volume 2.3. The Intergovernmental Panel on Climate Change (IPCC) classifies the human influence on ourclimate as extremely likely to be the main reason of global warming over the last decades. Particularly anthropogenic emissions of carbon compounds, with carbon dioxide…
SCC Volume 2.3. The observed present rate of uplift in Scandinavia increases from zero on the western coast of Norway to ~1 cm/yr in the Baltic Sea area. This domelike uplift is generally assumed to be the result of glacial…
SCC Volume 2.3. Transition from interglacial (Eem) to glaciation (Weichsel), to the current interglacial (warm) period, Holocene, including changing sea-levels: transgressions and regressions. Abstract Part 2 reviews some of the pertinent knowledge about ancient climate variations, from ~ 70 Ma…
SCC Volume 2.3. The source of atmospheric CO2 variations is poorly understood. At Mauna Loa Hawaii, atmospheric CO2 has been recorded from 1959. This is a short period for a reliable variability signature identification. From the 19th century, atmospheric CO2…
SCC Volume 2.3. The question is: What fraction of the observed increase in atmospheric CO2 since 1750 is due to the burning of fossil fuels? Is it close to 1.0 as the IPCC and the climate policy makers would have…
SCC Volume 2.3. Unlike elsewhere on the globe, temperature in the tropics has increased systematically. From observed tropical temperature, numerical simulations have reproduced the observed evolution of atmospheric CO2, including its annual cycle. Much the same has followed empirically from…
SCC Volume 2.2. A new data set of annually averaged CO2 background levels directly measured from 1826 to 1960 is presented. It is based on a selection process of about 100,000 single samplesfrom more than 200,000 available near ground on…
SCC Volume 2.2. Observed ocean and land CO2 data show both seasonal and spatial variations, where latitude is the most important in addition to the increase in time. A simple, approximative corrective procedure is proposed which will be of use…
SCC Volume 2.2. The Intergovernmental Panel on Climate Change classifies the human influence on our climate as extremely likely to be the main reason of global warming over the last decades. Particularly anthropogenic emissions of carbon dioxide are made responsible…
The question is: What fraction of the observed increase in atmospheric CO2 since 1750 is due to the burning of fossil fuels? Is it close to 1.0 as the IPCC and the climate policy makers would have us believe by…
SCC Volume 2.1. The existence or non-existence of the so-called atmospheric greenhouse effect continuously dominates the extremely emotional discussion about a human impact on global warming. Most scientists agree with the fundamental greenhouse theory, but like their opponents they are…
SCC Volume 1.2 Classical mathematicians valued simplicity, settling such complex questions as the irrationality of √2 by elementary methods. Today, too, refractory problems in pure as well as applied math- ematics are resoluble by simple, Classical methods. For instance, though…
SCC Volume 1.2 A basic assumption of climate change made by the United Nations Intergovernmental Panel on Climate Change (IPCC) is natural CO2 stayed constant after 1750 and human CO2 dominated the CO2 increase. IPCC’s basic assumption requires human CO2…
