CAMBRIDGE, Mass., Nov. 7, 2007 -- Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon ...

Magnesium isotope geochemistry has emerged as a pivotal tool in deciphering Earth’s surface and subsurface processes, particularly in the context of chemical weathering. By studying the subtle ...

Could blending of crushed rock with arable soil lower global temperatures? Researchers study global warming events from 40 and 56 million years ago to find answers. The Earth is getting hotter and ...

The natural rock weathering process, while effective in breaking down carbon and storing it within rocks over thousands of years, may not provide the immediate solution to combat climate change. With ...

The total area of global karst regions is approximately 22 million square kilometers, accounting for roughly 15% of the Earth's land surface. These regions ...

Hebrew University experts continue in footsteps of researcher who built special reactor that flushes CO2, seawater through ...

Scientists have discovered that chemical weathering, a process in which carbon dioxide breaks down rocks and then gets trapped in sediment, can happen at a much faster rate than scientists previously ...

During the Ordovician period, the concentration of CO2 in the earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the Ordovician ...

Rocks are not eternal. Even the tallest mountain will eventually dissolve and disintegrate. Geologists call this process “weathering.” It sounds harmless enough, but weathering is one of the most ...
