Newly released IPCC Report confirms grave risks in a warning world

Our future got much bleaker with the release of the first report in the sixth series from Intergovernmental Panel on Climate change (IPCC) on 9 August. Released just days before the World Youth Day, the report does not bode well for our future generations, reinforcing the same key messages from earlier IPCC annual reports. Urges changes must be made to limit global warming to the Paris agreements 1.5 degree Celsius temperature limit while there is still time
Invasive Insects: Risks and Pathways Project

Australia can’t afford to allow in any more insect colonists like red imported fire ants, electric ants, browsing ants, yellow crazy ants, Argentine ants, African big-headed ants, Asian honeybees, large earth bumblebees and German wasps. These invaders are costing both the Australian environment and economy dearly. Hundreds of millions of dollars are being spent on Australia-wide eradications of red fire ants, electric ants and browsing ants because of their potential for devastating harm to wildlife and impacts on people. The others have spread too far to remove, so are here in perpetuity as a threat to biodiversity, human amenity and the economy, and a burden for future generations to manage. Given the difficulties and costliness of eradicating or controlling invasive insects, one over-riding priority for Australian biosecurity must be to prevent more harmful species arriving and establishing. To do this, biosecurity authorities need to know which insects overseas (an estimated 4–6 million species) represent the greatest invasive risks for our country and how they are likely to arrive here. Biosecurity authorities already know which insects are the prevention priorities for agriculture, but there is no such list covering insects that could harm the Australian environment.

Recent years have seen large increases in the number and size of successful invasive species eradications from islands. There is also a long history of large scale removals on larger land-masses. These programmes for mammals and terrestrial plants follow the same cost-area relationship although spanning 10 orders of magnitude in scale. Eradication can be readily defined in island situations but can be more complex on larger land-masses where uncertainties defining the extent of a population, multiple population centres on the same land-mass and ongoing risks of immigration are commonplace. The term ‘complete removal’ is proposed to describe removal from an area with ongoing eff ort to maintain the area as clear, as features in many larger scale mainland programmes. Examples of complete removal to a boundary, in patches and in habitat islands are discussed. While island eradications continue to grow in scale, new legislation such as the lists of Species of European Union Concern will also drive increasing management on larger land-masses. However, these lists include large numbers of species that are already widespread. Methods are needed to prioritise species to reflect both the risks posed and the feasibility of management, including the effects of scale on cost and effectiveness.
Weed eradication on Raoul Island, Kermadec Islands, New Zealand: progress and prognosis

During the 45 years that the Raoul Island weed eradication programme has been underway, eleven species have been eradicated. To complete the restoration of Raoul Island’s unique ecosystems supporting signi?cant seabird biodiversity and endemic biota, nine further transformer weeds must be eradicated. In this review of progress to date, we examine the feasibility of eradication of these transformers and identify that four species are on target for eradication: African olive (Olea europaea subsp. cuspidata), yellow guava (Psidium guajava), castor oil plant (Ricinus communis) and grape (Vitis vinifera). However, for four more species more sta? resources are required to achieve eradication as currently infestations are establishing faster than they are being eliminated: purple guava (Psidium cattleianum), black passionfruit (Passi?ora edulis), Brazilian buttercup (Senna septemtrionalis) and Mysore thorn (Caesalpinia decapetala). The ninth species, Madeira vine (Anredera cordifolia), is being contained but presents logistical di?culties for e?ective control – herbicide resistant tubers and cli? locations requiring rope access in unstable terrain. Increasing the resources for this programme now to enable eradication of these transformer weeds will reduce the total long-term cost of the programme. Eradication of rats, the 2006 eruption, recent greater cyclone frequency, increased tourism requiring biosecurity management, and sta?ng reductions have all impacted progress on weed eradication. Myrtle rust (Austropuccinia psidii), con?rmed in March 2017 as the latest invasive species on Raoul Island, is establishing on Kermadec pohutukawa (Metrosideros kermadecensis), the dominant canopy species. The impact of this species on the weed eradication programme is unknown at this point.
The coral triangle and climate change: ecosystems, people and societies at risk: a comprehensive study involving over 20 experts and based on 300 peer-reviewed scientific articles

2009
This study brought together the experience, viewpoints and analysis of over 20 experts from the climate, biological, economic, policy and social sciences. The major focus of the study was to examine how the future might unfold for one of the most ecologically rich yet most populated regions of the planet. In doing so, this report has developed a series of policy recommendations which must be taken on board if we are to avoid a major environmental and human catastrophe. If we don’t do this, hundreds of thousands of unique species, entire communities and societies will be in jeopardy.
