Long-term ecosystem monitoring in Queensland has revealed a troubling change: parts of Australia’s tropical rainforests are now releasing more carbon than they absorb. These forests, once reliable carbon sinks, are becoming net carbon sources as rising temperatures and prolonged dry periods increase tree loss. The findings come from decades of field measurements across the Wet… Read more: Australia’s Tropical Rainforests Become Carbon Source

Methane remains one of the most damaging greenhouse gases released into the atmosphere, especially from agriculture and waste systems. A new line of environmental research highlights an unexpected ally in reducing these emissions: underwater microbes that naturally consume methane before it escapes into the air. Researchers are testing these microbes in controlled systems placed near… Read more: Underwater Microbes That Consume Methane Show Climate Promise

Artificial intelligence is expanding at a historic pace, but new research shows the environmental cost is rising just as quickly. A recent analysis from Cornell University warns that AI-driven data centres could strain energy grids, drain freshwater supplies, and significantly increase carbon emissions. Rising Energy Consumption AI data centres run powerful servers that operate around… Read more: The Environmental Footprint of AI: New Research Raises Concerns

In November 2025, the world’s attention will turn to Belém, Brazil, as it hosts the 30th United Nations Climate Change Conference (COP30). From November 10–21, global leaders, scientists, and policymakers will meet in the heart of the Amazon to discuss climate action, deforestation, and environmental justice. Why Belém Matters Holding COP30 in Belém is both… Read more: COP30 in Belém: The World Turns Its Eyes to the Amazon

The Atlantic Meridional Overturning Circulation (AMOC), one of Earth’s most important climate systems, may be closer to collapse than once believed. New simulations suggest that even under low-emission scenarios, the likelihood of a breakdown can no longer be considered low. Read more from The Guardian What is AMOC? The AMOC is a vast ocean conveyor… Read more: Atlantic Current Collapse Risk Rising
