As long as we continue to burn fossil fuels, the science tells us that these events will grow worse.

The impact is a "textbook case of climate injustice."

90% of homes in some impacted areas are made of sun-dried earth - structures that simply cannot withstand rainfall of this intensity.

Vulnerable communities are paying the price for a crisis they didn't cause. (3/4)

The current weak La Niña phase naturally brings wetter conditions to the region, but it is now operating in a much warmer, moisture-rich world.

While still a rare 1-in-50 year event, climate change acted as a "force multiplier," turning a heavy rain event into a more deadly deluge. (2/4)

Those with access to cooling relied heavily on solar - which met 60% of the peak demand during the heatwave - a major contrast from the fossil-fuel heavy responses to previous heatwaves. 5/6

That has a human cost: Melbourne’s airport saw temperatures top out at 44.4°C on Jan 9 and one hospital reported a 25% spike in emergency admissions. Heatwaves kill more Australians than all other natural hazards combined. 4/6

Yet the world continues to heat with 2.6°C of warming expected by the end of the century under current global policies. This would turn a once rare event into a normal part of the Australian summer. 3/6

Even with a weak La Niña - which typically brings cooler weather - fossil fuel emissions "far outweighed" natural cooling. This heatwave was 1.6°C hotter than it would have been in a world without human-caused warming. 2/6
