5 Οκτ 2018 · Flow behavior and mobility of gravitational mass flows such as rapid-moving landslides, ice-rock avalanches, or snow avalanches strongly depend on the material temperature. Flow temperature dependence is particularly pronounced for materials with high homologous temperatures, such as snow or ice under natural conditions.
4 Ιουν 2019 · There are two distinct changes that a condensible may bring about as gravity changes, one due to its radiative properties if it is a greenhouse gas and the other due to the release of latent heat when it condenses.
4 Σεπ 2017 · Abstract. Natural unforced variability in global mean surface air temperature (GMST) can mask or exaggerate human-caused global warming, and thus a complete understanding of this variability...
Today’s climate change is unlike any seen in the last 2,000 years, scientists report Wednesday in the journal Nature. New research shows that the civilization-altering warm and cold periods of recent human history, like the so-called Little Ice Age, did not occur across the entire globe but instead happened in isolated regions.
10 Νοε 2021 · These maps show global average surface temperature at different periods in Earth’s history going back 24,000 years. The darker the shade of blue, the colder the temperature compared to today.
Weight varies dramatically if we leave Earth’s surface. On the Moon, for example, acceleration due to gravity is only 1.67 m/s 2. A 1.0-kg mass thus has a weight of 9.8 N on Earth and only about 1.7 N on the Moon.
According to an ongoing temperature analysis led by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880.
