Air pollution can be natural or anthropogenic
2016 Key Finding2016 Sources of air pollution include industrial emissions; vehicle and road traffic emissions; dust; and smoke from domestic wood heaters, prescribed burning and bushfires.
Australia’s heritage remains vulnerable to both natural and anthropogenic threats
2016 Key Finding2016Climate change poses a major challenge for heritage owners and managers, and has the potential for high-impact and irreversible damage in the absence of remedial action. Natural areas continue to be affected by invasive species, loss of habitat and altered fire regimes. Economic growth...

Some pressures are increasing, with uncertain impacts on the marine environment
2016 Key Finding2016Since 2011, there has been an increase in most forms of vessel activity in marine waters. As a result, risks associated with grounding of vessels, anchor scouring, accidents at sea in ecologically sensitive areas, vessel strike of marine animals, and introduction of foreign marine...

Outlook for Australia’s climate 2016
2016 At a glanceAt a glanceThe outlook for Australia’s climate depends on the effectiveness of international and national efforts to reduce greenhouse gas emissions. Without mitigation, surface temperature increases of 3.7–4.8 °C above 1850–1900 temperatures are projected. To remain below 2 °C warming above...
The oceans have somewhat mitigated the effects of emissions
2016 Key Finding2016 The oceans absorb CO2 and heat, and thus limit the rate and immediate extent of changes in climate. In recent decades, the oceans have taken up around 25 per cent of the annual anthropogenic (human) CO2 emissions. However, the capacity of the oceans to absorb CO2 is limited, because...

Effects of increased greenhouse gases
2016 Report Content2016 Climate Pressures The growing concentrations of human-generated GHGs have resulted in an increased absorption, largely in the lower atmosphere, of the heat radiated from Earth’s surface, causing an increase in the...
Introduction 2016
2016 At a glanceThe capricious nature of our nation’s water resources was evident during 2011–16, with: record rainfall and record dryness at local, regional and state scales extended and extensive flooding national water storage levels varying from above 80 per cent to below 50 per cent groundwater...

Introduction 2016
2016 At a glanceAustralia has always been a land of extremes. In a single year, we can experience heatwaves, floods, fires, cyclones and drought. Australia’s highly variable climate is influenced year to year by large-scale drivers in the atmosphere and ocean, such as the El Niño–Southern Oscillation (ENSO...
