NASA analysis confirms 2023 as warmest year on record

Earth's average surface temperature in 2023 was the warmest on record, according to an analysis by NASA.

Bottled water contains 100 times more plastic nanoparticles

The average litre of bottled water has nearly a quarter of a million pieces of microplastics and tiny, invisible nanoplastics, new research has found. 

Rise of microplastics discovered in placentas of Hawaiʻi mothers

The study examined placentas donated by women who delivered in Hawaiʻi from 2006 to 2021. The rise in microplastics found in the placentas of Hawaiʻi mothers corresponds with the skyrocketing levels of global plastic production.

First marine fish declared extinct due to human activity

A rare species of ray has been declared extinct after an assessment by an international team led by Charles Darwin University. 

What octopus DNA tells us about Antarctic ice sheet collapse

This direct historical connection suggests that around 125,000 years ago, the massive 2.2 million cubic kilometer West Antarctic Ice Sheet that separates the two bays had fully collapsed into the sea.

Flowers adapting to a world without insects

New study reveals that as insect populations in Europe fall so some plants are turning to self-pollination.

Runaway Greenhouse Effect Fully Simulated on Earth For The First Time

The Earth would only have to heat up by a few dozen degrees to spur runaway warming, making it as inhospitable as Venus, a planet whose average surface temperature is around 464 degrees Celsius, according to NASA.

Antarctic study proves glacier has undergone irreversible retreat

Model results show that Pine Island glacier region of west Antarctica could collapse in the future. If it does, then it could raise global mean sea level by several metres.

We Could See Methane Emissions Skyrocket

Beneath one Arctic island's permafrost, millions of cubic meters of methane are trapped—and scientists have now learned that it can migrate beneath the cold seal of the permafrost and escape.

Longer daily commute linked to poor mental health

A recent study shows how a number of effects of longer daily commutes can snowball into depression. The study was conducted in South Korea, a country with some of the longest average commuting times.

The climate change we caused is here for at least 50,000 years

2023 has seen climate records being not just broken, but smashed. By September there had already been 38 days when global average temperatures exceeded pre-industrial ones by 1.5°C.

Nanoplastics linked to Parkinson's disease and dementia

Nanoplastics that can leach into water and soil affect a specific protein found in the brain, causing changes linked to Parkinson’s disease and other types of dementia.

The Hole in the Ozone Layer Is Getting Bigger Again

A large hole in the Antarctic ozone layer once thought to be steadily closing could actually be widening, according to new research.

Earth just passed a feared global warming milestone for the first time

Average global temperatures were more than 2 degrees Celsius above a pre-industrial benchmark on Friday, preliminary data show - an ominous milestone after months of record warmth. 

Marijuana Use Linked to Epigenetic Changes

Recent and long-term marijuana use is linked to changes in the human genome, a new study found. Although multiple states have legalized marijuana, the health consequences of marijuana use are not well understood.
