Understanding the movement of carbon dioxide (CO2) into and out of ecosystems in response to warming global temperatures is a crucial part of predicting how Earth’s climate will change in the future. Scientists have long expected that global warming will lead to plants increasing the amount of CO2 they release into the atmosphere through respiration. In turn, this would lead to even more warming in a positive feedback loop which would accelerate climate change.

When food runs out and competition heats up, nematodes assemble into living towers. They writhe and twist towards the sky with the goal of latching on to a passing animal to hitch a ride to more comfortable digs. Scientists had hypothesised this for decades, but no one had seen these aggregations form outside of the laboratory. Now, researchers in Germany have recorded the first video footage of nematodes “towering” in the real world in decaying apples and pears.

Experts are calling the findings of the latest State of the Climate in the South-West Pacific report a “wake up call” for stronger climate action in the region and globally. Experts say climate change is “changing the water cycle quite significantly.”According to the report, 2024 was the warmest year on record in the South-West Pacific region, at about 0.48°C above the 1991–2020 average.

When we think of droughts, the first thing that comes to mind is lack of rain. But there is another important driver at play – evaporation. Atmospheric Evaporative Demand (AED) to be exact. As AED increases, the atmosphere becomes thirstier, increasing evaporation, which dries out the landscape, particularly effecting regions with low soil moisture such as Australia.

On September 16, 2023, an unusual seismic signal shook the world. It appeared like clockwork every 90 seconds and lasted for 9 consecutive days. A month later, a similar signal reappeared and lasted for another week before disappearing. Scientists have since determined that these seismic anomalies were triggered by 2 massive landslides which ripped through a remote fjord in east Greenland.
