New Zealand can expect more days above 25℃, the threshold for heat stress in livestock, and fewer frost days, which will affect crops like kiwifruit that need winter chilling. Anita Wreford, Professor, Lincoln University, New Zealand Licensed as Creative Commons – attribution, no derivatives.

Food is a fundamental human right. But governments have left it to charities and food suppliers to step in after disasters. That has to change as climate change throws up greater stresses.

How does this compare to Australia’s previous floods? And can we expect more frequent floods at this scale under climate change? The answers aren’t straightforward.

We are no longer in typical conditions. Climate change is already damaging human and natural systems we hold dear in Australia.

As the impacts and costs of climate change increase over time, New Zealand’s financial systems could become less stable and the government less able to support those affected.

If estimates are grossly inaccurate, Australia’s emission reduction targets will not be grounded in a credible assessment of greenhouse gas outputs.

Russia supplies much of Europe’s gas. Will their invasion of Ukraine lead to a renewed push for energy independence?

That there’s legacy waste in Antarctica may come as a surprise to some, as we often think of Antarctica as a pristine wilderness. These photos show why cleaning up is long overdue Darren Koppel, Research fellow, Curtin University Licensed as Creative Commons – attribution, no derivatives.

Fusion seems nearer than ever - but it won’t be the silver bullet to stop climate change. Ian Lowe, Emeritus Professor, School of Science, Griffith University Licensed as Creative Commons – attribution, no derivatives.

The plan would address failures in the National Electricity Market, and would see a more orderly transformation process from coal to clean energy.

New research finds 74% of land managers who reported releasing a powerful biocontrol release it during the peak rabbit breeding period. This can lead to rabbit populations actually increasing. Pat Taggart, Adjunct Fellow, UNSW Sydney Licensed as Creative Commons – attribution, no derivatives.

Dry regions will get drier and wet regions wetter as the climate changes. How quickly? Quicker than we thought, unfortunately. Taimoor Sohail, Postdoctoral research associate, UNSW Sydney Jan Zika, Associate Professor, UNSW Sydney Licensed as Creative Commons – attribution, no derivatives.

The tertiary sector’s air miles may be dominated by a small number of hyper-mobile senior academics, but studies show virtual conferences can improve diversity, career development and emissions.

Compassionate conservationists believe all animals have a right to be here, even introduced species like wild horses. Their vocal critics are avoiding vital ethical questions around conservation.
