Editor's Notes
- What is this? This slide library provides a range of slides relating to presenting the SRCCL report. It is separated into sections in order to make access to each area more simple. The ‘introduction to report’ section provides a range of slides relating to background on the report, how it was created, the people involved etc. The ‘chapter X’ sections contain slides and figures that relate to the chapter/subject. The ‘all figures’ section contains all figures from the report on separate slides – you just need to insert them into your presentation. The ‘Subject’ sections contain slides that are more relevant to a particular subject area or audience, e.g. biodiversity, policy etc. How to use this presentation: This presentation is suitable for talks over 45 mins. For talks under 45 mins, please see the shortened version. Each section of the report is introduced with a high-level message. There are 4 in total for 4 sections. Figures have been included at the end of the presentation for presenter use. The slide notes are for supporting statements when delivering slides and include further contents from the report. The presenter can decide which to include based on their audience and area of specialty. In bold are the sections of each slide. E.g. Headline refers to the title of the slide. Numbered bullet points, e.g. 2. refer to the corresponding bullet point on the slide. Italicized text provides suggestions for where to include SPM figures or which audience particular statements are suitable for. Regarding the design/template To add a new slide, click new slide and choose one from the template. The slides are color coded (green, yellow, pink, light blue, dark blue). Slide numbers will be added automatically if you add a new slide this way. Notes For further supporting statements and figures, please see the Technical Summary or report chapters.
