The reports, meanwhile, can



      sometimes span several hundreds of


      pages, and are therefore accompanied



      by more concise summaries.






      In addition, assessment reports can


      take years to produce and can,



      therefore, be somewhat outdated by


      the time they are completed.






      Often, breakthrough research and



      observations are excluded because, at


      the time the report was initiated, this



      research was not available.






      Climate change is a direct result of


      human activity.
