The Chandler wobble or Chandler variation of latitude is a small deviation in the Earth's axis of rotation relative to the solid earth, [1] which was discovered by and named after American astronomer Seth Carlo Chandler in 1891. It amounts to change of about 9 metres (30 ft) in the point at which the axis intersects the Earth's surface and has ...
Precession means the Earth's nonuniform motion (see above) will affect different seasons. Winter, for instance, will be in a different section of the orbit. When the Earth's apsides (extremes of distance from the sun) are aligned with the equinoxes, the length of spring and summer combined will equal that of autumn and winter.
The total average energy per unit time radiated by Earth is equal to the average energy flux j times the surface area 4πR 2, where R is Earth's radius. On the other hand, the average energy flux absorbed from sunlight is the solar constant S 0 times Earth's cross section of πR 2, times the fraction absorbed by Earth, which is one minus Earth ...
Climate engineering (or geoengineering, climate intervention [1]) is the intentional large-scale alteration of the planetary environment to counteract anthropogenic climate change. [ 2 ] [ 3 ] The term has been used as an umbrella term for both carbon dioxide removal and solar radiation modification when applied at a planetary scale.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Together with planetary management, stewardship and environmental wisdom are different ways to manage the Earth [9] or "environmental worldviews". In particular: Planetary management focus its attention on humans needs and wants, while stewardship aim at the benefit of humans, organisms and ecosystems of the Earth: [9] in other words, planetary management considers humans as the most important ...
Climate action (or climate change action) refers to a range of activities, mechanisms, policy instruments, and so forth that aim at reducing the severity of human-induced climate change and its impacts. "More climate action" is a central demand of the climate movement. [1] Climate inaction is the absence of climate action.
to confront the global climate emergency. ... Today's interim report from the UNFCCC [1] shows governments are nowhere close to the level of ambition needed to limit climate change to 1.5 degrees and meet the goals of the Paris Agreement. The major emitters must step up with much more ambitious emissions reductions targets for 2030 in their Nationally Deter
