Understanding the role of climate change behind costly or deadly impacts allows for mitigation and response systems such as building codes or public health resources to be sufficiently bolstered, particularly as the risk of impacts increases.
This week, the Bureau of Meteorology (BOM) announced that an El Niño has been declared and is underway in Australia.
New science as Australia heads into an El Niño period.
The strength of the Pacific Walker Circulation is a major part of what determines if we are in a La Niña or El Niño period.
We can expect more intense and frequent El Niño and La Niña events.
Climate models suggest that the rainfall decrease and temperature increase during El Niño will likely intensify in the future.
New research finds a significant interaction between the El Niño-Southern Oscillation and Madden-Julian Oscillation, with major implications for Northern Australia.
Wet and dry periods could stick around for longer.
There’s now good evidence that even if we overshoot 1.5℃, we could still reverse it by ending emissions and soaking up excess greenhouse gas emissions.
Switching between El Niño and La Niña conditions has slowed over the industrial era.
