About

Translations: (Français) (English) (Български)

RealClimate is a commentary site on climate science by working climate scientists for the interested public and journalists and has been operating since Dec 2004. We aim to provide the context sometimes missing in mainstream commentary on climate science. The discussion here is mostly restricted to scientific topics though we maintain open threads for the political or economic implications of the science and for discussions of possible solutions. All posts are signed by the author(s), except ‘group’ posts which are collective efforts from the whole team. Please note this is a moderated forum.

Technical details

We use WordPress blogging software and are hosted at Openstack.com. Current site design is by Oliver Mösing. 

Google Custom Search results are from a subset of the web that we consider provide quality information on climate science. This includes scientific agencies, mainstream climate centres and universities around the world. 

Translations

We welcome translation efforts for all our substantive articles. Currently, we host translations of many articles that have been provided from the wider community and additionally we link to external translations. Availability is denoted by the appropriate language flag (note that national flags are merged if the languages are in common). If you would like to get involved translating either to the existing languages, or any new language, please let us know.

Disclaimer

The contributors to this site do so in a personal capacity during their spare time and their posts do not represent the views of the organizations for which they work, nor the agencies which fund them. The contributors are solely responsible for the content of the site and receive no remuneration for their contributions.

RealClimate is not affiliated with any environmental organisations. Although our domain was originally hosted by Science Communications Network (and previously Environmental Media Services), and our initial press release was organised for us by Fenton Communications, none of these organizations were in any way involved in the initial planning for RealClimate, and never had any editorial or other control over content. Neither Fenton nor SCN nor EMS ever paid any contributor to RealClimate.org any money for any purpose at any time. Neither did they pay us expenses, buy our lunch or contract us to do research. This information has always been made clear to anyone who asked.

Contact

If you would like to contact us, suggest a topic to be covered, contribute a relevant commentary, or be part of this effort on a more permanent basis, please email RealClimate (replace -at- with @). Please do not bother to send us press releases, newsletters or queries about link exchanges.

Anthropogenic Forcing

by

Translations: (Français)

Forcing due to human, rather than natural, factors. Such factors include increased greenhouse gas concentrations associated with fossil fuel burning, sulphate aerosols produced as an industrial by-product, human-induced changes in land surface properties among other things.

Atlantic Multidecadal Oscillation (“AMO”)

by

Translations: (Français)

A multidecadal (50-80 year timescale) pattern of North Atlantic ocean-atmosphere variability whose existence has been argued for based on statistical analyses of observational and proxy climate data, and coupled Atmosphere-Ocean General Circulation Model (“AOGCM”) simulations. This pattern is believed to describe some of the observed early 20th century (1920s-1930s) high-latitude Northern Hemisphere warming and some, but not all, of the high-latitude warming observed in the late 20th century. The term was introduced in a summary by Kerr (2000) of a study by Delworth and Mann (2000).

Climate Field Reconstruction (“CFR”)

by

Approach to reconstructing a target large-scale climate field from predictors employing multivariate regression methods. CFR methods have been applied both to filling spatial gaps in early instrumental climate data sets, and to the problem of reconstructing past climate patterns from ‘climate proxy’ data.

Climate Proxy

by

Translations: (Français)

Climate ‘proxies’ are sources of climate information from natural archives such as tree rings, ice cores, corals, lake and ocean sediments, tree pollen, or human archives such as historical records or diaries, which can be used to estimate climate conditions prior to the modern period (e.g. mid 19th century to date) during which widespread instrumental measurements are available. Proxy indicators typically must be calibrated against modern instrumental information to yield a quantitative reconstruction of past climate.
