Climate science in the context of "Biogeochemistry"

The Köppen climate classification divides Earth's climates into five main climate groups, with each group being divided based on patterns of seasonal precipitation and temperature. The five main groups are A (tropical), B (arid), C (temperate), D (continental), and E (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the E group are assigned a seasonal precipitation subgroup (the second letter). For example, Af indicates a tropical rainforest climate. The system assigns a temperature subgroup for all groups other than those in the A group, indicated by the third letter for climates in B, C, D, and the second letter for climates in E. Other examples include: Cfb indicating an oceanic climate with warm summers as indicated by the ending b., while Dwb indicates a semi-monsoonal continental climate, also with warm summers. Climates are classified based on specific criteria unique to each climate type.

The Köppen climate classification is the most widely used climate classification scheme. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, German climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system in 1954 and 1961, which is thus sometimes called the Köppen–Geiger climate classification.

In climate science, longwave radiation (LWR) is electromagnetic thermal radiation emitted by Earth's surface, atmosphere, and clouds. It is also referred to as terrestrial radiation. This radiation is in the infrared portion of the spectrum, but is distinct from the shortwave (SW) near-infrared radiation found in sunlight.

Outgoing longwave radiation (OLR) is the longwave radiation emitted to space from the top of Earth's atmosphere. It may also be referred to as emitted terrestrial radiation. Outgoing longwave radiation plays an important role in planetary cooling.

Deep time is the concept of geological time that spans billions of years, far beyond the scale of human experience. It provides the temporal framework for understanding the formation and evolution of Earth, the development of life, and the slow-moving processes that shape planetary change. First developed as a scientific idea in the 18th century and popularized in the 20th century by writers such as John McPhee, the concept of deep time has influenced fields ranging from geology and evolutionary biology to climate science, philosophy, education, and environmental ethics. Today, deep time is increasingly used in science communication and public engagement, offering a powerful lens for understanding human impact during the Anthropocene.

The National Center for Atmospheric Research (NCAR /ˈɛnkɑːr/) is a US federally funded research and development center (FFRDC) managed by the nonprofit University Corporation for Atmospheric Research (UCAR) and funded by the National Science Foundation (NSF). NCAR has multiple facilities, including the I. M. Pei-designed Mesa Laboratory headquarters in Boulder, Colorado. Studies include meteorology, climate science, atmospheric chemistry, solar-terrestrial interactions, environmental and societal impacts.

The editorial board at The Wall Street Journal writes opinion articles in The Wall Street Journal and selects opinion articles by outside parties for publication. The editorial board is known for its very conservative positions, which at times bring it into conflict with the Journal's news division.

The Journal is regarded as a forum for climate change deniers, publishing articles by people who reject the consensus position on climate change in its op-ed section. A 2011 study found that the Journal was alone among major U.S. print news media in adopting a false balance that overplays the uncertainty in climate science or denies anthropogenic climate change altogether.
