More than half of the digital data firms generate is collected, processed and stored for single-use purposes. Often, it is never re-used. In 2020, digitisation generated 4% of global greenhouse emissions.
The Southern Ocean has dominated the global absorption of heat. In fact, Southern Ocean heat uptake accounts for almost all the planet's ocean warming, thereby controlling the rate of climate change.
Researchers found "giant" viruses – several times larger than typical viruses – affecting microscopic algae just below the boundary between fresh water and salt water.
Relentless rains in Pakistan over two months have caused the country's worst flooding in more than a decade. Floodwaters have washed away roads, buildings, and crops. A third of the country is now underwater.
The overall conclusion of the report is that climate change, habitat loss, invasive species, pollution, and resource extraction have pushed Australia's environment into a serious and severely deteriorating state.
On top of intensifying algal blooms and depleting oxygen, a new study reveals Earth's bodies of freshwater are also evaporating at a greater rate than we realized.
There is an even chance that global temperatures will temporarily breach the benchmark of 1.5 degrees Celsius above pre-industrial levels in one of the next five years, the United Nations warned.
The ocean memory decline is expected to make it significantly harder for scientists to forecast upcoming ocean dynamics. It will hinder our ability to project monsoons, marine heatwaves and periods of extreme weather, among other things.
Fish on Australia's Great Barrier Reef are losing their colour as coral reefs degrade and die during bleaching events, a new study shows.
Eastern Antarctica has recorded exceptionally high temperatures in March, more than 30 degrees Celsius above normal, say experts.
The increase in global CO2 emissions of over 2 billion metric tons in 2022 is the largest in history in absolute terms, more than offsetting the previous year's pandemic-induced decline.
Warmer oceans can lead to large amounts of methane being released from the seabeds, which may amplify climate warming.
Baltimore city, US government officials want oil companies to pay for their direct contributions to climate change. In Baltimore, citizens have suffered the devastating effects associated with climate change.
By 2080, around 70% of the world's oceans could be suffocating from a lack of oxygen as a result of climate change, potentially impacting marine ecosystems worldwide.
Projections suggest that stronger, tornado-producing storms may be more likely as global temperatures rise, though strengthened less than we might expect from the increase in available energy.
