The ARC Centre of Excellence for Climate Extremes has contributed to a new scientific study that reveals that extremely hot and cold temperatures, drought and heavy rainfall strongly affect the year-to-year variation in the total global yield of four important crops.
Large areas of northern Queensland experienced extreme rainfall and severe flooding in late January and February 2019. This briefing note examines the impacts and some of the likely causes of the event.
Weather and climate extremes occur on a wide range of time and space scales. Weather extremes occur on shorter timescales and are regionally or locally specific while climate extremes tend to be on longer timescales and can impact a region through to the whole globe. This note provides a statement on what we know about how weather and climate extremes might change in the future.
Briefing note 003: Why are we uncertain about how extremely wet conditions will change in Australia in the future?February 11, 2019 4:08 pm Comments Off on Briefing note 003: Why are we uncertain about how extremely wet conditions will change in Australia in the future?
Computer models used to simulate global climate agree the climate will warm in response to increasing atmospheric greenhouse gases. However, a recent paper by Bador et al. (2018)1 includes results that highlight our uncertainty about exactly how extremely wet conditions will change in Australia. Further development of Australia’s national climate model, ACCESS, may help reduce this uncertainty.
The Australian FLUXNET data provide perhaps the world’s most valuable observations for building and evaluating the land models needed for projecting future droughts and heatwaves.
