Brief description The Marine chapter of the 2021 State of the Environment (SoE) report incorporates multiple expert templates developed from streams of marine data. This metadata record describes the Expert Assessment "Pressures on the marine environment - climate change - frequency and severity of extreme weather events". ***A PDF of the full Expert Assessment, including figures and tables (where provided) is downloadable in the "On-line Resources" section of this record as "EXPERT ASSESSMENT 2021 - Frequency and Severity of Extreme Weather Events"*** ---------------------------------------- DESCRIPTION OF PRESSURE Extreme weather events represent pressures to the marine and coastal environments through severe storm-induced winds (including tropical and extratropical cyclones) which can cause wind damage and storm surges, heatwaves or shorter-term heat extremes which can stress infrastructure and natural barriers, extreme rainfall events which can cause flooding and erosion, and extreme dry conditions – in particular drought – which can stress natural coastal systems such as mangroves. Aside from the delimited identification of cyclones as either tropical (north of the Tropic of Capricorn (ToC)) and extratropical (south of the ToC), all other listed pressures can affect all coastal regions of Australia. DATA STREAM(S) USED IN EXPERT ASSESSMENT Literature. ---------------------------------------- 2021 SOE ASSESSMENT SUMMARY [see attached Expert Assessment for full details] • 2021 • Assessment grade: High impact Assessment trend: Unclear Confidence grade: Somewhat adequate: Adequate high-quality evidence or high level of consensus at a national scale Confidence trend: Limited evidence or limited consensus Comparability: N/A – new assessment ---------------------------------------- CHANGES SINCE 2016 SOE ASSESSMENT Not previously assessed.
