About the show

The team at Zephyr Environmental brings you conversations and discussions with various experts in the fields of climate change, atmospheric science, carbon and emerging technologies.
Join us each month for a new episode.


  • Episode 8: COP28: Climate Action or COP out?

    December 1st, 2023  |  47 mins 26 secs

    The Conference of the Parties (or COP) are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change. These serve as the formal meeting of the UNFCCC parties to assess progress in dealing with climate change.

    COP28 will convene in the United Arab Emirates in November and December of this year. The conference serves as a possible (and crucial) chance to bring the world together to tackle the climate crisis.

  • Episode 7: Connecting to Country to combat the climate crisis

    November 8th, 2023  |  33 mins 1 sec

    Indigenous cultures and traditions are built upon sharing natural resources. Australia’s First Nations peoples have cared for Country for sixty-five thousand years with both innovative and traditional land management practices and play a crucial role in the ecosystems we all inhabit.

    The impact of climate change can endanger the survival of indigenous communities both in Australia and worldwide. Indigenous people are and will be uniquely impacted by climate change and with unrivalled knowledge of the land, this must be included in the challenge of combatting climate change.

  • Episode 6: Going Nuclear: the future of small-scale nuclear power

    October 4th, 2023  |  56 mins 39 secs

    The idea of nuclear power in Australia has been hotly debated for decades. Today we’re going to talk about whether the new breed of nuclear power plants are part of the solution to the climate crisis and how air quality links into the nuclear energy discussion.

  • Episode 5: Hunting for Methane Monsters: measurement, reporting and verification of greenhouse gas emissions

    September 5th, 2023  |  50 mins 40 secs

    Methane is a greenhouse gas emitted from coal mines, oil and gas wells, landfills, wetlands and the agriculture sector. Methane emissions are the second largest contributor to climate change and it is more potent in the atmosphere than carbon dioxide (CO2). This means there are potential “quick wins” in targeting methane reductions early in the decarbonisation process.

    Satellite data of total-column methane concentration is being used to estimate methane emissions on a global scale. Recent media headlines suggest that methane emissions from the oil & gas and coal mining sectors could be underestimated.

    Our pod today is going to explore satellites, methane measurement methods and the future of methane emissions.

  • Episode 4: London's Killer Smog 70 years on - what have we learnt?

    August 1st, 2023  |  54 mins 25 secs

    December 2022 marked 70 years since the Great Smog of London which claimed 12,000 lives. This event lead to a significant change in air quality management and control and the emergence of the Clean Air Act of 1956. This month's guest, Dr Gary Fuller, talks about the Great Smog of 1952, amongst other things in his book 'The Invisible Killer: The Rising Global Threat of Air Pollution- and How We Can Fight Back'. This podcast revisits the Great Smog of London and the air quality progress that we've made since.

  • Episode 3: The Australian Direct Air Capture Machine

    July 5th, 2023  |  28 mins 11 secs

    We are all aware that global emissions will need to be reduced to limit global warming below 1.5 or 2 degrees Celsius above pre-industrial temperatures.
    Another part of the ‘climate change arsenal’ involves the capture and/or extraction of carbon dioxide (CO2) from the atmosphere.
    And that’s where this month’s podcast takes us – to direct air capture.

  • Episode 2: Are we heading for a super El Nino?

    June 2nd, 2023  |  27 mins 38 secs

    From late 2020 to the middle of 2022, the world experienced a triple La Nina which brought a record amount of rainfall to south-east Australia.
    The latest reports suggest that we could now be heading for not only an El Nino but a super El Nino. So what is this? And is this likely to happen?
    In this episode we talk to associate professor Dr Andrea Taschetto about all things La Nina and El Nino and whether a super El Nino may happen.

  • Episode 1: Can science save the planet?

    May 5th, 2023  |  40 mins 23 secs

    We are all aware of the impact that climate change is having across the world. The facts are there to see.
    Sometimes we can get lost in the 'doom and gloom' of these statistics and we spend less time and attention on how the world could effectively tackle the climate crisis. And that's where science comes in.
    In this episode we talk to climate scientist Dr Helen Cleugh about how science can save the planet.
