A global analysis of groundwater levels reports rapid declines of over 0.5 meters per year are widespread and that declines have accelerated over the past four decades in 30% of the world's regional aquifers. The study also shows cases in which depletion trends have reversed following interventions such as policy changes. [62] [63]
2020: NASA and SOFIA (Stratospheric Observatory for Infrared Astronomy) discover about 12 US fl oz (350 ml) of surface water in one of the Moon's largest visible craters. [140] 2022: The standard reference gene, GRCh38.p14, of the human genome, is fully sequenced and contains 3.1 billion base pairs. [141
The Global Carbon Budget 2021 concludes that fossil CO 2 emissions rebounded by around +4.8% relative to 2020 emissions – returning to 2019 levels, identifies three major issues for improving reliable accuracy of monitoring, shows that China and India surpassed 2019 levels (by 5.7% and 3.2%) while the EU and the US stayed beneath 2019 levels ...
The water cycle refers to the complex system by which water moves around the Earth. ... as the river reached its lowest level on record during the most intense and widespread drought the country ...
Regular, hexagonal ice is also less dense than liquid water—upon freezing, the density of water decreases by about 9%. [36] [e] These peculiar effects are due to the highly directional bonding of water molecules via the hydrogen bonds: ice and liquid water at low temperature have comparatively low-density, low-energy open lattice structures.
Mar. 2—It may seem like a recent trend for more women to be entering STEM fields, but women have a long history of contributing to innovations in science, technology, engineering and mathematics.
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
An especially notable irregular maximum density is that of water, which reaches a density peak at 4 °C (39 °F). This has important ramifications in Earth's ecosystem . [ 1 ]
