Over recent decades the stratosphere has cooled while stratospheric ozone has decreased. Low temperatures could be causing further ozone depletion, which may delay recovery of the ozone layer.

Oct 17, 2011 · Volcan Parinacota (“flamingo lake” in the Aymara language) is a potentially active stratovolcano located on the Altiplano, a high plateau in the Andes mountains of west-central South America. While no direct observations of eruptive activity have been recorded, surface exposure dating of lava flows suggests that activity occurred as recently as 290 AD (± 300 …

Climate Forcings and Global Warming Any changes to the Earth’s climate system that affect how much energy enters or leaves the system alters Earth’s radiative equilibrium and can force temperatures to rise or fall. These destabilizing influences are called climate forcings. Natural climate forcings include changes in the Sun’s brightness, Milankovitch cycles (small variations …

Methane is an important trace gas in Earth’s atmosphere. Even though it only makes up 0.00017% (1.7 parts per million by volume) of the the atmosphere, methane traps a significant amount of heat, helping the planet remain warm and habitable. The amount of methane in the atmosphere is the result of a balance between production on the surface and destruction in the …

Colorless, odorless, and poisonous, carbon monoxide is one of the six major air pollutants regulated in the United States and in many other nations around the world. When carbon-based fuels, such as coal, wood, and oil, burn incompletely or inefficiently, they produce carbon monoxide. The gas is spread by winds and circulation patterns throughout the lower …

Red and green colors predominate in this view of the Aurora Australis photographed from the Space Shuttle in May 1991 at the peak of the last geomagnetic maximum. The payload bay and tail of the Shuttle can be seen on the left hand side of the picture. Auroras are caused when high-energy electrons pour down from the Earth’s magnetosphere and collide with atoms. Red …

Earth’s temperature depends on how much sunlight the land, oceans, and atmosphere absorb, and how much heat the planet radiates back to space. This fact sheet describes the net flow of energy through different parts of the Earth system, and explains how the planetary energy budget stays in balance.

May 2, 2020 · An astronaut onboard the International Space Station (ISS) took this photograph using a short camera lens, capturing almost all of Mexico in one shot. The wide field of view is framed by the center window of the ISS Cupola module and includes a solar array of the Northrop Grumman Cygnus cargo spacecraft. This view encompasses most of Mexico’s mountain …

The Sea in many places is here cover’d with a kind of a brown scum, such as Sailors generally call spawn; upon our first seeing it, it alarm’d us, thinking we were among Shoals, but we found the same depth of Water were it was as in other places. Sailing through the Coral Sea outside the Great Barrier Reef, Captain James Cook made those observations on August 28, 1770. His …
