Human activities responsible for rapid increase in Earth's heat Human activities responsible for rapid increase in Earth's heat Increases in greenhouse gases, decreases in aerosols and polar sea-ice, are major factors 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.

Low-oxygen waters off Washington, Oregon coasts risk becoming large 'dead zones' Low-oxygen waters off Washington, Oregon coasts risk becoming large 'dead zones' A large area of poorly oxygenated water is growing off the coast of Washington and Oregon. Scientists say oxygen levels may fall low enough to create "dead zones." Read more
Deforestation, warming flip part of Amazon forest from carbon sink to source Deforestation, warming flip part of Amazon forest from carbon sink to source The study area, which represents about 20 percent of the Amazon basin, has lost 30 percent of its rainforest New results from a nine-year research project in the eastern Amazon rainforest finds that significant deforestation in eastern and southeastern Brazil turned what was once a forest that absorbed carbon dioxide into a source of planet-warming carbon dioxide emissions.

Earth has two different stratospheres, and aviation may be to blame Earth has two different stratospheres, and aviation may be to blame Findings suggest aircraft emissions may alter the stratosphere at mid-high latitudes 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
Carbon dioxide peaks near 420 parts per million at Mauna Loa observatory 7Jun2021 Read more In May, NOAA's measurements at the Mauna Loa observatory averaged 419.13 parts per million. Scientists at Scripps calculated a monthly average of 418.92 ppm. It's the highest level since accurate measurements began 63 years ago. Read more
