An international team of chemists and climate scientists, has conducted an assessment of the impact of short-lived halogens (SLHs) on Earth's atmosphere and are suggesting that their findings indicate that such gases should ...
The COVID pandemic shutdowns in South Asia greatly reduced the concentration of short-lived cooling particles in the air, while the concentration of long-lived greenhouse gases was barely affected. Researchers were thus able ...
