Microbe waste can shed light on Earth's evolution

 Microbe waste may provide a record of how Earth and life co-evolved over the past 3.5 billion years as the planet's temperature, oxygen levels and greenhouse gases changed, scientists say.

The US space agency, NASA, is developing the Global Ecosystem Dynamics Investigation (GEDI) Lidar device to map forests on Earth in 3D and increase understanding of their role in the carbon cycle.

Southern Ocean iron cycle provides new insight into climate change

Researchers have found that deep winter mixing, a seasonal process which carries colder and deeper, nutrient-rich water to the surface, plays very crucial role in transporting iron to the surface.

Charcoal from wildfires pouring copiously into oceans via rivers

Wild fires not only destroy millions of trees each year but the residue is transported to the sea by rivers which penetrates the carbon cycle, a recent study has revealed.

`Twilight` microbes that capture carbon discovered

Mysterious organisms in the dark depths of the ocean are converting carbon dioxide into a form useful for life.
