‘SHE UNDERSTANDS WHAT A SENTENCE NEEDS TO DO AND BE TO ACHIEVE A KIND OF PERFECTION’

– Sean O’Toole, journalist & art critic

A recipient of the South African National Parks Environmental Journalist of the Year Award, I’ve reported for leading African and international media for 21 years, including Daily Maverick’s Our Burning Planet unit, Travel Africa, the American Polar Society’s Polar Times, the Lonely Planet Guide to Antarctica and the Sunday Times. Becoming in 2010 the first female journalist to spend a summer with the South African National Antarctic Programme at the bottom of the planet, I have an ongoing and special interest in polar affairs (both the Arctic and the Antarctic), global change issues, natural sciences, the climate crisis and space sciences.

I work as a senior investigative science journalist for Daily Maverick, joint winner of the Global Shining Light investigative journalism awards with 2021 Nobel Peace Prize laureate Maria Ressa.

Here my mission is to investigate the latest developments in international sciences, what they highlight about our relationship with the cosmos during the Anthropocene, and how science may be weaponised by vested interests.

Environmental reporter Don Pinnock and I were the world’s first journalists to run an in-depth, exclusive report on the potential links between Covid-19 and its recombinant origins in pangolins, among the planet’s most trafficked and endangered mammals. This article revealed seminal initial findings by US scientists. Our report was published on the same day that a Chinese university announced a similar preliminary hypothesis. A week later, the US team became the first scientists globally to share their study when they posted it to the preprint forum bioRxiv. Since then, the forum has been flooded with research, including the Chinese findings, on how the 2019/2020 pandemic strain may have used pangolins as an intermediate vector. Read the full story

New findings released this month by the journal Nature Communications reveal that English-language digital and print media give 49% more coverage to bush-league climate contrarians than top scientists. We asked Professor Guy Midgley, a Stellenbosch University expert on how biodiversity responds to the climate crisis – with the odds in favour of ‘at scale climate change disinformation’, as the study puts it, what’s the best way for ordinary people to make sense of this wilderness?
