Don’t Let Climate Risk Fade: The Hidden Costs of Complacency You Can’t Afford to Ignore

The dismissal of the authors behind the Sixth National Climate Assessment by the Trump administration raised eyebrows. It highlights a bigger issue—climate change is urgent and affects us all. While the U.S. has published five assessments, Australia is still working on its first National Climate Risk Assessment.

Comprehensive climate risk assessments help us prepare for future challenges. They use scientific data to inform policies that protect people, infrastructure, and the economy. Australia is fortunate to have resources detailing how climate change affects us.

For instance, we know the southern regions are getting drier. Flooding is more severe when it occurs. Extreme temperatures are on the rise, bushfire conditions are increasing, and our seas are warming and rising. But what we don’t fully understand is how these changes will affect us. Without clear data, we risk making poor decisions that could harm vulnerable communities.

Experts warn that heatwaves cause more deaths than any other natural disasters in Australia. Not only do they impact health, but they also strain our resources. For example, heatwaves can disrupt electricity supply, harm crops, and make outdoor work impossible.

Moreover, heatwaves affect specific groups, like the elderly or those in remote areas. Anyone who can’t easily adapt is at greater risk. In severe cases, whole communities may become unlivable.

Additionally, multiple climate hazards often overlap, creating compounded risks. For instance, a heatwave can coincide with a fire or flooding, leading to disastrous outcomes.

In March 2024, Australia released its first National Climate Risk Assessment, marking a significant step forward. Experts identified 56 major climate risks that need addressing. This assessment is a game-changer; it allows us to budget effectively for a future impacted by climate change. Proper planning usually results in cheaper adaptation costs.

Recent trends show rising insurance costs tied to climate risks, pointing to the urgency of understanding and addressing these hazards. Experts recommend updating the National Climate Risk Assessment every five years to account for new data. This ensures we’re prepared for the changing climate landscape.

Climate change isn’t going away, even with immediate action. Some impacts are already set in motion for thousands of years. Understanding what we stand to lose demands ongoing assessment at all levels—global, national, and local.

The recent U.S. assessment situation serves as a warning. Dismissing climate risk assessments is dangerous. We need regular evaluations to safeguard our future. Stopping the process could have dire consequences, making the push for continuous assessment more critical than ever.
