Explanation:
Green house effect occurs when the wavelenght of the infrared radiation in the incident solar radiation, looses some of its energy on reflection from the earth surface, making it longer and unable to pass through the greenhouse gases that act like a blanket around the earth.
The reflected radiation has a longer wavelenght because it looses energy to the earth as heat; leaving it with a new wavelenght too long to go through the greenhouse gases.
The jar envoirment does not provide the earth-like material that can absorbs some of the energy of the incident radiation so it goes out with relatively the same energy. Also, the refractive index of the green house gases and the glass used in the lab might not be the same so modeling it with a glass might not produce the same effect.
Finally, the light source used might not contain enough infrared energy as an incident solar radiation.

Abstract
Most planetary systems are formed within stellar clusters, and these environments can shape their properties. This paper considers scattering encounters between solar systems and passing cluster members, and calculates the corresponding interaction cross-sections. The target solar systems are generally assumed to have four giant planets, with a variety of starting states, including circular orbits with the semimajor axes of our planets, a more compact configuration, an ultracompact state with multiple mean motion resonances, and systems with massive planets. We then consider the effects of varying the cluster velocity dispersion, the relative importance of binaries versus single stars, different stellar host masses, and finite starting eccentricities of the planetary orbits. For each state of the initial system, we perform an ensemble of numerical scattering experiments and determine the cross-sections for eccentricity increase, inclination angle increase, planet ejection, and capture. This paper reports results from over 2 million individual scattering simulations. Using supporting analytic considerations, and fitting functions to the numerical results, we find a universal formula that gives the cross-sections as a function of stellar host mass, cluster velocity dispersion, starting planetary orbital radius, and final eccentricity. The resulting cross-sections can be used in a wide variety of applications. As one example, we revisit constraints on the birth aggregate of our Solar system due to dynamical scattering and find N ≲ 104 (consistent with previous estimates).
Explanation:
International sources which they belong to all countries of the world .Example water,sea,oceans etc. oceanic resources beyond to 200 kilometre of exclusive economic zone is internationally owned resources which is regulated by International Institute . for instance every country given some rights over the oceans to specific range.

Answer:
Hurdles in achievement of sustainable energy
Explanation:
One of the biggest hurdles in sustainability is that of the Human Behaviour, Poverty, migration and marginalization of poor, the example of changing customer requirements and rising the demand Second is climate change and global warming. Example of depletion of natural resources and increase of man led disasters. The conflict that arises from disputed related to natural resources availability. Such as the sharing of rivers at borders. Thirdly the crimes conducted against the environment like illegal deforestation and trade of species hence destruction of their natural environment.
