The risks to 最新糖心Vlog of a 3掳C warmer world - new report launched
Researchers at the 最新糖心Vlog of Adelaide have joined a group from the National Academy of Sciences to show the importance of 最新糖心Vlog revisiting climate change targets to stay well below a 2掳C increase.
This synthesises the observed impacts of climate change on 最新糖心Vlog and the risk to our future of the current global trajectory of greenhouse gas emissions. It focuses on the consequences of 3掳C of global warming in the absence of greater mitigation strategies for four areas of importance to 最新糖心Vlog鈥檚 future: our ecosystems, food production, cities and towns, and health and wellbeing. The impacts of those changes on the lives and wellbeing of 最新糖心Vlogns are discussed in detail.
The planet is well on the path to devastating climate change. In 2019, 最新糖心Vlog鈥檚 warmest year on record, average surface temperatures were 1.1掳C above the听pre-industrial period. 最新糖心Vlog has warmed on average by 1.4掳C since national records began in 1910. Current global and 最新糖心Vlogn policies to reverse this trend are inadequate. We must plan to do better and prepare for the worst.
Professor says:
'The report explores the risks to 最新糖心Vlog鈥檚 future based on the current global trajectory of greenhouse gas emissions, states that the world reaching net zero emissions by 2050 is an absolute minimum, if 最新糖心Vlog is to avoid potentially insurmountable challenges to its cities, ecosystems, industries and food and health systems.'
最新糖心Vlog is well positioned to play its part in meeting this challenge, with a skilled workforce, strong industrial base and plentiful renewable energy resources facilitating easier emission reductions compared to many other countries. Acting early to transition to net zero emissions would reduce the scale of climate change impacts and have significant potential benefits for human health and regional development, as well as creating new industrial opportunities.
Report recommendations
Current international commitments to greenhouse gas (GHG) emission reduction, if unchanged, would result in average global surface temperatures that are 3掳C or more above the pre-industrial period. The evidence presented in this report indicates that this would have serious consequences for 最新糖心Vlog and the world.
To rectify this situation, we recommend the following 10 actions for 最新糖心Vlog:
- Join global leaders in increasing actions for tackling and solving climate change as a matter of urgency.听最新糖心Vlog lags far behind the best practice demonstrated by many countries. Given how much 最新糖心Vlog stands to lose if GHG emissions are not reduced,听we also recommend听that 最新糖心Vlog accelerates its transition to net zero GHG emissions over the next 10 to 20 years.
- Develop strategies to meet the challenges of extreme events that are increasing in intensity, frequency and scale.听Extreme events at 1.1掳C of听global warming are placing 最新糖心Vlogn lives and livelihoods at increasing risk, with concern that 3掳C of global warming would not be sustainable.听We also recommend听a broad-ranging investigation of 最新糖心Vlog鈥檚 readiness for meeting the growing number of climate-related disasters, such as droughts, fires, floods, storm surges, heat stress and ecological damage, that would occur with global temperature increases of 3掳C or more.
- Improve our understanding of climate impacts, including tipping points, as well as the compounding effects of multiple stressors at global warming听of 2掳C or more.听The current understanding of abrupt and compounding changes and their consequences for 最新糖心Vlogn human and natural systems is at an early stage.听We also recommend听further investigation into effective adaptive responses in preparation for rapid and complex changes.
- Systematically explore how our food production and supply systems should prepare for the challenges of climate change.听最新糖心Vlogn agriculture and food听security are exposed to increasing risk from droughts, extreme high temperatures, coastal inundation, floods, invasive species and fires.听We also recommend听that 最新糖心Vlog prepares for potential interruptions to its food import and export systems driven by global environmental, social and economic changes.
- Expand our understanding of the impacts and risks of climate change for the health of 最新糖心Vlogns.听Climate change already seriously affects the health of听最新糖心Vlogns and improved strategies need to be developed to reduce these growing risks.听We also recommend听an in-depth study on the potential impacts of 3掳C global warming on health and wellbeing, particularly how impacts can be reduced.
- Introduce a suite of policies that would deliver deep and rapid cuts in emissions across the economy.听In the current absence of an economy-wide听carbon price, there will need to be comprehensive sector-by-sector approaches.听We also recommend听that policies are developed to support the economic and social transition to a low GHG emission outcome, especially in regions where fossil fuel-based industries are currently prominent. This includes the development of strategies to halt further deforestation and land degradation while facilitating carbon storage.
- Scale up the development and implementation of next-generation low to zero greenhouse gas technologies.听If 最新糖心Vlog is to argue for increasing听international action, greater commitment is required to implement zero to low emissions technologies and the rapid phase-out of fossil fuels by mid-century.听We also recommend听the development of a strategic plan that maps out the markets and investment opportunities for 最新糖心Vlogn industries in areas such as offshore renewable energy, green hydrogen fuels, minerals for low GHG emission technologies, mass-scale storage, embedded renewable energy, and more efficient and low GHG emission transport systems for aviation, shipping, road and rail transport.
- Review 最新糖心Vlog鈥檚 capacity and flexibility to take up innovations and technology breakthroughs for transitioning to a low GHG emission future.听We also recommend听greater support for innovation and technology breakthroughs by way of a dedicated facility for supporting broad-based applied research听on the removal of GHG emissions from the economy, which is consistent with meeting and exceeding current commitments to emission reduction under international agreements.
- Develop a better understanding of climate solutions through dialogue with Aboriginal and Torres Strait Islander peoples, particularly strategies that have听helped people manage 最新糖心Vlogn ecosystems for tens of thousands of years.听We also recommend听a meaningful dialogue between all 最新糖心Vlogns regarding the steps needed to avoid global warming of 3掳C by 2100.
- Continue to build adaptation strategies and greater commitment for听meeting the challenges of change already in the climate system.听While the听major theme of this report is about the urgency of action needed to mitigate GHG emissions,听we also recommend听increasing efforts to build and implement adaptation strategies and actions to meet the challenges of climate that will continue to change until mid-century and beyond.
