As the summer continues many of us are experiencing very hot temperatures. It is important to be prepared for extreme conditions which can lead to heat stress.
We used an atmospheric model from the Met office in the UK called the unified model to simulate one of the black summer bushfire events.
The presence of groundwater in forested areas reduces rainfall loss in wet periods and maintains soil moisture in dry periods.
This study is an example how models help us to examine and understand how ocean currents behave and how they impact our environment.
There are many types of climate models, and they vary widely in complexity.
The oceans’ biology and chemistry influence the climate because ocean, atmospheric and land processes are all interconnected.
This research has the potential to create RCM emulators that can efficiently downscale multiple variables simultaneously, while preserving the physical relationships between them.
Tipping points exist in the climate system, and it is very unlikely that all tipping points are known. Different tipping points are understood with different levels of confidence, they operate on different timescales, can interact to trigger cascades of abrupt changes, and some tipping point changes are irreversible on timescales of centuries to millennia.
Conditions in the Indian Ocean can affect the risk of Australia experiencing droughts, floods, marine heatwaves and bushfires and alter the prospects for rainfed agriculture in some parts of the country.
Irrespective of tipping points, climate change adaptation efforts will be less costly and disruptive to society – and will stand a better chance of success – if warming can be limited to 1.5°C rather than 2°C or higher.
