Ocean heat, a strong marker of climate change, reached a record high in 2022, helping to explain the ever-escalating pattern of extreme weather events of late.
Jellyfish populations are currently on the rise, and this growth can negatively impact humans and other living organisms unless change is implemented.
According to the new paper, 16 of 35 planetary vital signs have now reached record extremes. That includes rises in the frequency of dangerous heat events, global tree cover loss from fires and the prevalence of the mosquito-borne dengue virus.
NASA scientists, using a tool designed to study how dust affects climate, have identified more than 50 spots around the world emitting major levels of methane, a development that could help combat the potent greenhouse gas.
Researchers looked at soil and lake sediment from Lake Hazen, the largest lake by volume north of the Arctic Circle. Sequencing segments of DNA and RNA found in the soil, the scientists sought to identify the pool of viruses present in the environment.
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.
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.
