Greenhouse Gas Emissions and its Main Drivers: a Panel Assessment for EU-27 Member States [PDF]

open access: yesAmerican International Journal of Business Management, Vol. 5. No. 4, pp. 138-146 (2022), 2022
This paper assesses the effects of greenhouse gas emissions drivers in EU-27 over the period 2010-2019, using a Panel EGLS model with period fixed effects. In particular, we focused our research on studying the effects of GDP, renewable energy, households energy consumption and waste on the greenhouse gas emissions.

Robust Model-based Reinforcement Learning for Autonomous Greenhouse Control [PDF]

open access: yesarXiv, 2021
Due to the high efficiency and less weather dependency, autonomous greenhouses provide an ideal solution to meet the increasing demand for fresh food. However, managers are faced with some challenges in finding appropriate control strategies for crop growth, since the decision space of the greenhouse control problem is an astronomical number. Therefore,

The runaway greenhouse radius inflation effect - An observational diagnostic to probe water on Earth-size planets and test the Habitable Zone concept [PDF]

open access: yesA&A 628, A12 (2019), 2019
Planets similar to Earth - but slightly more irradiated - are expected to enter into a runaway greenhouse state, where all surface water rapidly evaporates, forming an optically thick H2O-dominated atmosphere. For Earth, this extreme climate transition is thought to occur for a ~6% increase only of the solar luminosity, though the exact limit at which ...

The Effect of External Debt on Greenhouse Gas Emissions [PDF]

open access: yesarXiv, 2022
We estimate the causal effect of external debt on greenhouse gas emissions in a panel of 78 emerging market and developing economies over the 1990-2015 period. Unlike previous literature, we use external instruments to address the potential endogeneity in the relationship between external debt and greenhouse gas emissions.

Indirect long-term global radiative cooling from NOx emissions [PDF]

open access: yes, 2001
Anthropogenic emissions of short‐lived, chemically reactive gases, such as NO x and CO, are known to influence climate by altering the chemistry of the global troposphere and thereby the abundance of the greenhouse gases O3, CH4 and the HFCs.

The Effect of Diffuse Light on Crops [PDF]

open access: yes, 2008
Light is not evenly distributed in Dutch glass greenhouses, but this can be improved with diffuse light. Modern greenhouse coverings are able to transform most of the light entering the greenhouse into diffuse light. Wageningen UR Greenhouse Horticulture

Improved Loss Function-Based Prediction Method of Extreme Temperatures in Greenhouses [PDF]

open access: yesarXiv, 2021
The prediction of extreme greenhouse temperatures to which crops are susceptible is essential in the field of greenhouse planting. It can help avoid heat or freezing damage and economic losses. Therefore, it's important to develop models that can predict them accurately.

Impact of effective polarisability models on the predicted release dynamics of CH$_4$ and CO$_2$ from premelted ice [PDF]

open access: yesPhysical Chemistry Chemical Physics 2019, 2018
We present a theory for Casimir--Polder forces acting on greenhouse gas molecules dissolved in a thin water film. Such a nanosized film has recently been predicted to arise on th surface of melting ice as stabilized by repulsive Lifshitz forces. We show that different models for the effective polarizability of greenhouse gas molecules in water lead to ...

Global climate change : greenhouse effect [PDF]

open access: yes, 1992
One of the main problems caused by climate change is the greenhouse effect. Human activities emit so-called greenhouse gases into the atmosphere, such as carbon dioxide which is produced through fossil fuel burning.

Greenhouse Effect in the Classroom: A Project- and Laboratory-Based Curriculum [PDF]

open access: yes, 2001
This article describes a multifaceted curriculum for use in earth science classes from secondary school to undergraduate level. The centerpiece of the curriculum is a project-based investigation of greenhouse warming that can be conducted during one or ...
