Climate models are complex mathematical models designed by meteorologists, geophysicists, and climate scientists to simulate and predict climate. Given temperature predictions from the top 20 climate models worldwide, and over 100 years of historical temperature data, we track the changing sequence of which model currently predicts best. We use an algorithm due to Monteleoni and Jaakkola that m...

The current and future strength of the terrestrial carbon sink has a crucial influence on the expected climate warming on Earth. Usually, Earth Observation (EO) by its very nature focusses on diagnosing the current state of the planet. However, it is possible to use EO products in data assimilation systems to improve not only the diagnosis of the current state, but also the accuracy of future p...

The Arctic ice caps and glaciers serve as important indicators of climate change and also make a small, but significant, contribution to changes in global sea level. Consequently, understanding their mass balance is of considerable interest. We are examining the current state of mass balance of the major Canadian ice caps in the greater Baffin Bay area in the context of recent climate condition...

the application of ion current signals is one of the most recent approaches in engine management systems. by applying a small constant dc voltage across the electrodes of the spark plug and measuring the current through the electrode gap, the state of gas may be measured and investigated. in this paper a computer code is developed in order to analyze the state of gas during the combustion perio...

The potential effect of invasive plant species on biodiversity is one of most important subject of inquiry at present. In many parts of the world, the alarming spread of these plants has been documented. Knowing that climate exerts a dominant control over the distribution of plant species, predictions can therefore be made to determine which areas the species would likely spread under a climate...

Large climate feedback uncertainties limit the accuracy in predicting the response of the Earth’s climate to the increase of CO2 concentration within the atmosphere. This study explores a potential to reduce uncertainties in climate sensitivity estimations using energy balance analysis, especially top-of-atmosphere (TOA) radiation imbalance. The time-scales studied generally cover from decade t...
