Climate change - sea temperature

This assessment summary component has changed from 2011.

  • Many components identified as physical and chemical processes in SoE 2011 are collectively presented under impacts associated with the pressure of climate change in SoE 2016. This is because many of the changes being observed in these components during the SoE reporting period are the direct result of changes occurring as a result of climate change. This thereby avoids repetition of content between sections of the SoE report.

The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting

Sea level rise, increasing ocean temperatures and acidity are beginning to have significant impacts in all regions, and these effects are expected to increase. The worst affected areas are in the south-east and south-west, and are irreversibly and very seriously impacted.

Climate change - dissolved oxygen and oxygen minimum zones

This assessment summary component has changed from 2011.

  • Many components identified as physical and chemical processes in SoE 2011 are collectively presented under impacts associated with the pressure of climate change in SoE 2016. This is because many of the changes being observed in these components during the SoE reporting period are the direct result of changes occurring as a result of climate change. This reflects the move of the assessment of Low oxygen - dead zones from the 2011 State and trend of physical and chemical processes section.

The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting
cycles.

Pressures resulting from climate change
Sea level rise, increasing ocean temperatures and acidity are beginning to have significant impacts in all regions, and these effects are expected to increase. The worst affected areas are in the south-east and south-west, and are irreversibly and very seriously impacted. Changes in ocean current dynamics driven by climate change are also affecting these two regions

Approach/Process

Expert assessment based on a standardised phone interview and snowball sampling. The following background was provided to experts, and then the questionnaire was administered:

'Recreational fisheries management is predominantly the responsibilities of the states. For national State of the Environment (SoE) reporting, we are approaching you as a state-based identified expert in recreational fishing to provide advice. Collegial advice will be collected over the phone by CSIRO and guided by Table 1 (below). Additional comments made during discussion may also be noted to provide further insight. All information provided by participants will remain confidential. A semistructured agenda, comprising both open-ended and closed questions has been developed to collect advice on a range of topics (Table 1). Questions will take approximately 10–20 minutes to complete and data will be entered by the organiser. The open-ended items were developed to include topics about state recreational fisheries status, trends and key recent research. The closed component of the agenda was based on the "key to grades trend assessment" provided as background for developing SoE reporting. For a variety of agenda items, you will be asked to indicate a degree of agreement or disagreement using either a three- or a four-point Likert scale. As a participant, you will be asked to respond to the questions in the context of your state, unless your expertise is at a national level. A snowball sampling strategy will be used, with you asked to identify other experts to contact to participate in the virtual workshop.'

Table 1. Questions for virtual workshop with recreational fisheries experts

Open-ended questions:

  • Workshop participant information: name, email, affiliation, category: manager, researcher or stakeholder, sex, % rec-fish work, location and state, number of years working in rec-fish, specific interests. Are your responses at the state and/or national level?
  • Can you identify key research and reports on your state’s rec-fish since 2010–11?
  • After discussion, can you identify any recent changes in rec-fish including management since 2011 with 5 keywords or short phrases?
  • What is your state's main source of research investment?
  • What are the ranked 3 most important (tonnage) targeted fish/invertebrates?
  • Can you rank recent (since 2011) general trends in rec-fish a) effort, b) participation and c) harvest? Using this scale 1) decrease, 2) stayed the same, 3) increase or n/a) unsure,

Closed grade (assessment) questions:

  • Does recreational fishing currently have: 1) minor, 2) some, 3) substantial, 4) widespread or n/a) unsure, pressure on the environment?
  • How confident are you in the scientific evidence for your answer? 1) low, 2) limited or 3) high
  • How confident are you of state expert consensus on your answer? 1) low, 2) limited or 3) high
  • For the following pressure points on the environment can you rank pressure as 1) low, 2) limited, 3) high or n/a) unsure? Pressure points: habitats, specific species/taxa groups, physical environment, biogeochemical processes, biological processes or ecological processes.
  • Combining all of these pressure points, has the general trend of pressure from recreational fishing on the state environment since 2011: 1) reduced, 2) remained stable, 3) increased or is this n/a) unclear?
  • How confident are you in the scientific evidence for your answer to the trend question? 1) low, 2) limited or 3) high
  • How confident are you of state expert consensus on your answer to the trend question? 1) low, 2) limited, 3) high or n/a) unsure
  • Are there others that I should talk to as a recognized expert on recreational fishing in your State or elsewhere?

The literature review required a synthesis of the extent and trend in traditional use. The review included key material based on national and state-based studies, grey literature, government and non-government reports and scientific journal articles.

Assessment Summary Key

Grades

Very low impact

There are few or negligible impacts from this pressure, and accepted predictions indicate that future impacts on the environmental values of the region are likely to be negligible

Low impact

There are minor impacts from this pressure in some areas, and accepted projections indicate that future impacts on the marine environment are likely to occur, but will be localised

High impact

The current environmental impacts from this pressure are significantly affecting the values of the region, and projections indicate serious environmental degradation in the marine environment within 50 years if the pressure is not addressed

Very high impact

The current environmental impacts from this pressure are widespread, irreversibly affecting the marine environment, and projections indicate widespread and serious environmental degradation in the marine environment within 10 years if the pressure is not addressed

Recent Trends

  • Improving

  • Stable

  • Deteriorating

  • Unclear

Confidence

  • Adequate: Adequate high-quality evidence and high level of consensus

  • Somewhat adequate: Adequate high-quality evidence or high level of consensus

  • Limited: Limited evidence or limited consensus

  • Very limited: Limited evidence and limited consensus

  • Low: Evidence and consensus too low to make an assessment

Comparability

  • Comparable: Grade and trend are comparable to the previous assessment

  • Somewhat comparable: Grade and trend are somewhat comparable to the previous assessment

  • Not comparable: Grade and trend are not comparable to the previous assessment
