You know my opinion. I'm convinced we are in a planetary climate emergency and that we must urgently demand drastic changes.
But I'm only a layman. So what do the experts think about all this?
Here is part of a statement from a group of climate scientists, including Prof Craig Cary, University of Waikato, Prof Steven Chown, Monash University, distinguished Prof Sharon Robinson, University of Wollongong, Dr Charles Lee, University of Waikato, and assistant Prof Cassandra Brooks, University of Colorado Boulder...

"Antarctica’s heat waves are a warning to humanity – and we have only a narrow window to save the planet"
Antarctica is currently experiencing dramatic changes at unprecedented rates, marked by repeated extreme events. These include circum-Antarctic summer heatwaves and an autumn heatwave last year, with temperatures soaring up to 40C above the average. Moreover, both last summer and this winter, sea ice extent has reached record lows. These changes have happened even faster than scientists predicted.
Simultaneous changes in the Antarctic and Southern Ocean, and elsewhere around the globe, reflect the intimate connection between Antarctica and the rest of the Earth system. Our lives and our future depend on a healthy and functioning Antarctica.
The scope of the unusual occurrences in Antarctica extends beyond just biological systems. Other records have been shattered, with this year witnessing sea ice levels plummeting to unprecedented lows according to the satellite record. Last year an alarming, widespread heatwave hit large areas of Antarctica, causing, at some locations, a 35-40C temperature rise above long-term averages. Extreme temperature events have been observed in various other parts of the continent, including the Antarctic peninsula.
Antarctica is a crucial component of the Earth system and a sentinel for growing change. As Antarctic scientists, we see the evidence of mounting change, including changes in food webs, rapid change in populations, breeding failure and local ecosystem collapse, with projections of rapid transformation of a region that makes our planet liveable and contributes in extraordinary ways to global biodiversity.
This is a critical moment, impacting our well-being, future generations and ecosystems globally. Confronted by this evidence, we urgently call on nations to intensify and exceed their current commitments to greenhouse gas emissions reductions.
We have a narrow window for change. Events in the Antarctic we have observed and catalogued, and the projections from our research suggest that the window is closing fast.
The time for critical action is right now. What we do today will determine our future for centuries. We all deserve a brighter future. Together, we can make a difference.
