Global temperature variations over the last 1000 years
Temperature variation over the last 100 years by country and region (top) as well as global average (bottom).
The major driving factors behind climate variation over geological time scales.
The Wikimedia 2030 strategy was designed with climate change in mind.

This WikiProject is concerned with the coverage of climate change (Q125928) and related entities, both on Wikidata and across Wikimedia projects.


Background[edit]

Climate change[edit]

The climate on our planet has always varied over time, but the current period of global warming goes beyond what human civilizations have ever experienced and is driven by our activities, especially greenhouse gas emissions.

Wikimedia projects[edit]

Wikimedia projects are a group of online platforms that grew out of Wikipedia. All of them have some level of engagement with climate change. Counterclockwise, starting on top: Wikimania, Wikibooks, Meta-Wiki, Wikiquote, Wikispecies, MediaWiki, Wikimedia Incubator, Wikivoyage, Wikidata, Wikiversity, Wiktionary, Wikinews, Wikisource, Wikimedia Commons, Wikipedia. Most of them exist in multiple languages (e.g. Wikipedia in ca. 300) — together, they form an ecosystem of about 1000 wikis, each with their own community that interacts with other communities both within and beyond the Wikimedia movement.

Wikidata[edit]

Wikidata is integrated with all the other wikis in the Wikimedia ecosystem and links them with the wider Linked Open Data world. It does so by

  • having an entry (named item) for any concept covered on any Wikipedia, for any book edition covered in Wikisource or Wikibooks, for any species covered in Wikispecies, and so on;
  • having other kinds of entries (named properties) that link items
    • to entries in Wikimedia wikis
    • to each other
    • to external resources
  • having linguistic entries (lexemes, forms and senses) for potentially any word in any language and linking them to the corresponding items via dedicated properties
  • being multilingual in its user interface, allowing people to collaborate even if they do not share a common natural language
  • allowing the data to be queried and visualized in a variety of ways

WikiProjects[edit]

There are various ways in which community members and subgroups organize and interact. One of them are WikiProjects like this one, which typically coordinate activities on a certain topic across one wiki within the ecosystem. Others include user groups, thematic organizations or Wikimedia chapters. Several initiatives exist that focus on climate change or related topics. Lots of other such initiatives — e.g. the Wikipedia & Education User Group, WikiProject Chemistry or Wikimedia Medicine — have a scope that intersects with activities related to climate change.


Events[edit]

While most of the activities around climate change and Wikimedia take place on-wiki with little dedicated coordination, there are various initiatives that bring together multiple contributors for joint activities either online or in some specific locations, e.g. for article writing contests or editathons.

Items[edit]

Main items[edit]

Sorted in ascending order of their Wikidata identifier, i.e. from oldest to youngest. See also the query for items within scope.

Other items[edit]

Main queries[edit]

Items within scope[edit]

The following query uses these:

  • Properties: on focus list of Wikimedia project (P5008) View with Reasonator View with SQID
    1 select ?item ?itemLabel
    2 where
    3 { 
    4   ?item wdt:P5008 wd:Q69524601 . # item is within scope of the project
    5   SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    6 }
    


Items within scope by type[edit]

The following query uses these:

  • Properties: on focus list of Wikimedia project (P5008) View with Reasonator View with SQID, instance of (P31) View with Reasonator View with SQID
    1 select ?typeLabel (count(distinct ?item) as ?count)
    2 where
    3 { 
    4   ?item wdt:P5008 wd:Q69524601 . # item is within scope of the project
    5   ?item wdt:P31 ?type .          # type of item
    6   SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
    7 } group by ?typeLabel order by desc(?count)
    


Timeline of creation of items within scope[edit]

The following query uses these:

  • Properties: on focus list of Wikimedia project (P5008) View with Reasonator View with SQID, quantity (P1114) View with Reasonator View with SQID, point in time (P585) View with Reasonator View with SQID
     1 #defaultView:AreaChart
     2 SELECT ?date ?cumulativecount 
     3 {
     4     hint:Query hint:optimizer "None".
     5     {   SELECT ?milestonep (COUNT(?item) as ?cumulativecount)              # cumulative count of items meeting the filtering criteria below
     6         WHERE
     7         {
     8           { SELECT ?item { ?item wdt:P5008 wd:Q69524601 .}  LIMIT 100000 } # items within scope of the project
     9           BIND( xsd:integer( substr(str(?item), 33)) as ?qid)              # get the QID of the item
    10           wd:Q38074555 p:P1114 ?milestonep .                               # get list of QID milestones
    11           ?milestonep ps:P1114 ?milestone .
    12           FILTER( ?milestone > ?qid )                                      # only consider milestones newer than the item
    13         }
    14         GROUP BY ?milestonep
    15     }          
    16     ?milestonep pq:P585 ?date                                              # get the date when the QID milestone was reached
    17 }
    

Other queries[edit]

Items for which at least one sitelink has a quality badge[edit]

The following query uses these:

  • Properties: on focus list of Wikimedia project (P5008) View with Reasonator View with SQID
    1 SELECT ?sitelink ?itemLabel ?badge ?badgeLabel WHERE {
    2   ?item wdt:P5008 wd:Q69524601.    # item is within the focus of WikiProject Climate Change
    3   ?sitelink schema:about ?item;    # sitelinks about the item
    4      wikibase:badge ?badge .       # sitelink has a quality badge
    5     SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en" } .
    6 } ORDER BY ?badgeLabel
    

Items without a picture but with at least one sitelink that has a quality badge[edit]
