Earth has two different stratospheres, and aviation may be to blame 30Jun2021 Read more Findings of a new study of aerosols in the remote atmosphere finds that the northern stratosphere is significantlly more polluted than the south. Analysis of the aerosols suggests aviation is to blame. Read more
Human activities responsible for rapid increase in Earth's heat 28Jul2021 Read more A new study by Princeton University and NOAA researchers has found clear evidence of human influence on Earth’s climate in the past two decades of satellite measurements. “Human activity strongly influenced the positive trend in Earth's energy imbalance, causing a significant increase in the heat stored in the planet,” said Shiv Priyam Raghuraman, the lead researcher on the study.
