3 ημέρες πριν · Air pollution, release into the atmosphere of various gases, finely divided solids, or finely dispersed liquid aerosols at rates that exceed the natural capacity of the environment to dissipate and dilute or absorb them. High concentrations can cause undesirable health, economic, or aesthetic effects.

5 ημέρες πριν · The atmosphere of Earth is the planetary atmosphere of Earth, composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans ), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes ), all retained by Earth's gravity.
2 ημέρες πριν · The current global average concentration of carbon dioxide (CO 2) in the atmosphere is 421 ppm (0.04%) as of May 2022. [1] This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. [2] [1] [3] The increase is due to human activity.
1 ημέρα πριν · An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [94] The substance can be solid particles, liquid droplets, or gases, and often takes the form of an aerosol (solid particles or liquid droplets dispersed and carried by a gas). [95]
1 ημέρα πριν · Climate change is also causing gravity, buoyancy, pressure, inertia and spin to interact in the atmosphere in increasingly complex ways. For example, as Earth warms, atmospheric oscillations known ...
2 ημέρες πριν · In the PNAS study the ETH Zurich researchers show that climate change is also increasing the length of the day by a few milliseconds from its current 86,400 seconds. This is because water is flowing from the poles to lower latitudes and thus slowing down the speed of rotation. If the Earth continues to warm up, climate change will have a ...
1 ημέρα πριν · Other factors included local changes in nitrogen deposition from air pollution, rainfall, and land cover. The findings appeared to be confirmed by a 2021 study at University of California, Berkeley assessing the rate of photosynthesis in a range of ecosystems worldwide. Using a network of “flux towers” that measure the exchange of gases ...
