the evening meal comes during the hour of Shen, and the sun sinks completely at Yu; 戌黄昏而人定亥。 twilight sets in at Xu, and people rest by the hour of Hai. 譬于大数,若到戌会之终,则天地昏曚而万物否矣。 This sequence may also be understood macrocosmically At the end of the epo...
However, if Earth were a little closer to the Sun, its oceans would evaporate; if it were farther from the Sun, the oceans would freeze solid. [#highlight12]Because liquid water was present, self-replicating molecules of carbon, hydrogen, and oxygen developed life early in Earth’s history...
Multi-year La Niña and El Niño events became more common over the past 7,000 years because of orbital forcings causing gradual changes in upper-ocean stratification in the Tropical Eastern Pacific, according to an analysis of proxy records and palaeoclimate modelling. ...
Changes in seafloor topography, resulting from tectonic, magmatic and sedimentary processes, influence Arctic and global climate via a multitude of impacts on ocean pathways and energetics. This Review explores the past and present links between Arctic bathymetry, tectonics, oceans and climate. ...
I don’t know how to save the world. I don’t have the answers or The Answer. I hold no secret knowledge as to how to fix the mistakes of generations past and present. I only know that without compassion and respect for all of Earth’s inhabitants, none of us will survive—nor wil...
The second application examined the efficacy of one of the most used Earth science communication tools: paleogeographic maps. These maps visualize what the Earth looked like anciently and are used in a wide array of settings to communicate past eras and contextualize modern changes in climate. I ...

Similar reasoning suggested that one could estimate total elapsed geologic time by dividing the average thickness of sediment transported annually to the oceans into the total thickness of sedimentary rock that had ever been deposited in the past. Unfortunately, such estimates did not adequately account...
