Alert! Native plants spread across Antarctica and worry scientists

Recent photographic records have revealed a surprising scenario in Antarctica, where two species of flowering plants, once considered rare on the icy continent, are spreading.

Antarctic hairy weed (Deschampsia antarctica) and the Antarctic pear (Colobanthus quitensis), the only native angiosperms in the region, are gaining ground, and scientists point to global warming as the main driver of this change.

Worrying changes in Antarctica

Antarctica’s harsh and cold climate, with 98% of its territory covered in snow, has historically limited plant growth in the region.

However, recent discoveries indicate that temperatures rising are changing this scenario.

Mariana Cabral de Oliveira, professor at the USP Biosciences Institute, highlights that climate change is the catalyst for this transformation.

Researchers at the University of Washington have documented an extraordinary temperature rise in Dome C on the Antarctic Plateau, reaching about 39°C above average.

This thermal anomaly, which challenges the region’s extreme conditions, worries scientists and highlights the urgency of addressing greenhouse gas emissions.

Ilana Wainer, professor of Physical Oceanography at USPhighlights the complexity of reversing the current scenario in Antarctica, highlighting the need for investments in scientific research and global mitigation strategies.

Since 1959, the Antarctic Treaty has established strict regulations to prevent contamination of the continent, but the changes observed now require a broader and more collaborative approach.

As the scientific community seeks to understand ongoing phenomena, the proliferation of plants in Antarctica serves as a warning of the need for urgent action to combat climate change.

The preservation of the region’s unique biome depends on collective effort and the implementation of effective measures to reduce polluting gas emissions.

As native plants spread across Antarctica, it is crucial that the international community takes urgent action to address the challenges posed by global warming and protect this unique ecosystem vital to the planet’s climate balance.
