Schnell and Harde: The Negative Greenhouse Effect – Part I
In two consecutive studies, the suitability of different experimental set-ups for detecting and measuring the emission of infrared-active gases is investigated, as this is of particular importance for understanding the atmospheric greenhouse effect. The first part presents a horizontally arranged Styrofoam box, as described occasionally in the literature for such experiments. The gases are slightly…
Robbins: Sea Surface Temperature and CO2
Close examination of the small perturbations within the atmospheric CO2 trend, as measured at Mauna Loa, reveals a strong correlation with variations in sea surface temperatures (SSTs), most notably with those in the tropics. The temperature-dependent process of CO2 degassing and ab-sorption via sea surfaces is well-documented, and changes in SSTs will also coincide with…
Green&Soon: Are Climate Model Forecasts Useful for Policy Making?
Effect of Variable Choice on Reliability and Predictive Validity For a model to be useful for policy decisions, statistical fit is insufficient. Evidence that the model provides out-of-estimation-sample forecasts that are more accurate and reliable than those from plausible alternative models, including a simple benchmark, is necessary. The UN’s IPCC advises governments with forecasts of…
