24 February 2022, The Conversation: Climate change is warping our fresh water cycle – and much faster than we thought. Fresh water cycles from ocean to air to clouds to rivers and back to the oceans. This constant shuttling can give … Continue reading →

13 January 2021, ABC: As the Arctic melts, a regime shift is taking place. The Arctic is changing faster than any environment on Earth. The old order is being swept away, leaving scientists to ask: What’s coming in its place? Where there was once ice, there is now open ocean. Milky swirls of plankton, hundreds of kilometres in length, now bloom where polar bears once roamed. It is a spectacular sight looking down from space. The Arctic is exploding with new life — but not as we know it. Microscopic phytoplankton is the foundation of the marine food chain. It has increased in abundance in the Arctic by more than 50 per cent since the 1990s. Last August, plankton numbers in the seas north of Siberia increased by 600 per cent.

3 December 2020, The Conversation, ‘Severely threatened and deteriorating’: global authority on nature lists the Great Barrier Reef as critical. The Great Barrier Reef is now in “critical” condition and the health of four other Australian World Heritage properties has worsened, according to a sobering report just released by the International Union for Conservation of Nature (IUCN). The IUCN is the global authority on nature. Its third outlook report marks the first time the IUCN has declared an Australian property as critical, which means its values are severely threatened and deteriorating. The health of the Blue Mountains, Gondwana Rainforests, Shark Bay and the Ningaloo Coast has also been downgraded. The assessment, while chastening, is not surprising. The Great Barrier Reef has endured three mass coral bleaching events in five years, and last summer’s bushfires caused untold damage in the Blue Mountains and Gondwana Rainforests (not to mention the current fires at the reef’s Fraser Island). Climate change remains the key issue for World Heritage places, not just in Australia but globally. In fact, the IUCN assessment found climate change threatens 11 of Australia’s 16 properties. This raises further questions over our national climate response. Read more here
