Abrupt permafrost thaw found to intensify warming effects on soil CO₂ emission
According to a recent study published in Nature Geoscience, scientists have found that soil carbon dioxide (CO2) emissions are more sensitive to climate warming in permafrost-collapsed areas than in non-collapsed areas......»»
Here"s why we should put a gravitational wave observatory on the moon
Scientists detected the first long-predicted gravitational wave in 2015, and since then, researchers have been hungering for better detectors. But the Earth is warm and seismically noisy, and that will always limit the effectiveness of Earth-based de.....»»
