A planet does not have to have a moon to be a planet. Pluto has numerous moons but is not a planet in the same sense as Earth. Also, Mercury has no moons but is a fully-fledged planet like Earth. All the gas planets, including Jupiter and Neptune, have rings of dust. Jupiter's ...
What planet is between Jupiter and Uranus? What are planetary boundaries? What is Uranus' asteroid belt? What is a brown dwarf planet? Which is not a planet: the moon, Earth or Mars? What planet is between Venus and Mars? What planets have the greenhouse effect?
Why does the planetary boundary layer occur? The planetary boundary layer is the lowest layer of thetroposphere where wind is influenced by friction. The thickness (depth) of the PBL is not constant. What are the nine planetary boundaries?
However, the evidence base is limited as most studies are based on a single environmental aspect, such as climate impact, contrived dietary scenarios that don't reflect the full array of foods typically eaten, or dietary patterns that are not nutritionally adequate. In this study, a weighted ...
Action on climate alone is insufficient without also addressing nature and other planetary boundaries. Adaptation is now a critical ingredient in climate action, with countries and companies starting to take action on health, water, food, and nature. There are steps leaders can take to accelerate...
Sustainability is further explained through Donut Economics, an economic model developed by economist Kate Raworth, leveraging the concepts of Planetary Boundaries and Fundamental Human Needs. This framework is an attempt to provide a compass to replace the impossible neoliberal economic goal of endless ...
Plastic is a problem. But it's a material that's spearheaded economic growth for decades. Learn how to reconcile our desire for performance, convenience and value with the burning need to reduce our reliance on petrochemicals, creating an economy that functions within planetary boundaries. What's...
The planetary climate is a measure of the long-term trends in the weather. Various factors are known to influence the climate, including ocean currents, surface albedo, greenhouse gases, variations in the solar luminosity, and changes to the planet's orbit. Based on historical records, the Eart...
Rockström, J., Steffen, W., Noone, K., Persson, Å., Chapin, F.S., III., Lambin, E., Lenton, T.M., Scheffer, M., Folke, C., Schellnhuber, H., Nykvist, B., De Wit, C.A., Hughes, T., van der Leeuw, S., Rodhe, H., et al.: Planetary boundaries: exploring the...
A great book need not even be a best seller in its own day. It may take time for it to accumulate its ultimate audience. The astronomer Kepler, whose work on the planetary motions is now a classic, is reported to have said of his book that 鈥渋t may wait a century for a reader,...
