Rocket Launches and Reentries Harm Earth’s Ozone Layer
8 June 2026 @ 1:23 pm
Solid-state fuels—recently used to help launch astronauts to the Moon for the first time in decades—appear to be the fuel type with the most detrimental effects on the ozone.Potential landslides and liquefaction from the 8 June 2026 M=7.8 earthquake offshore Mindanao in the Philippines
8 June 2026 @ 7:19 am
Initial analyses suggest that the earthquake this morning has the potential to have triggered significant numbers of landslides and areas of liquefaction. At the time of writing, the impacts of the M=7.8 earthquake that occurred offshore the south coast of Mindanao in the Philippines remain unclear. Initial reports in the local press suggest 15 fatalities […]Mangroves May Be Losing Their Grip on Carbon Storage as Sea Levels Rise

Historical Volcanic Eruptions Mitigated the Expected Rapid Arctic Sea Ice Decline Prior to 2000, Wang et al., Geophysical Research Letters
Arctic sea ice has declined at sharply contrasting rates over the past four decades—modest before 2000 and rapid thereafter. Using observational and model evidence, we show that large tropical volcanic eruptions can trigger decade-long Arctic sea ice recoveries, and that without the 1982 El Chichón and 1991 Pinatubo eruptions, Arctic sea ice would have declined approximately 1.5 times faster before 2000. We further show a model's sensitivity to volcanic aerosol forcing scales with its sens
The EPA, IPCC, and many independent studies have found that electric vehicles have lower lifetime emissions than gas-powered vehicles in nearly all cases.
“Lifetime” calculations include emissions released during EV manufacture, as well as the generation o
