The new “geographic fire” defines the risk of wildfires in the southern United States
USDA Forest Service researchers combined the risks of fire and smoke emissions to people, infrastructure and basins to map expected wildfire risks across the southeast. Credit: USDA Forest Service The risk of wildfires is increasing in the southeast. Fire control allows fuel to accumulate in forests, droughts become more common, and communities are developing more homes and infrastructure in forested…

Healing ozone holes can help southern oceans take up carbon, research reveals
Credit: Pixabay/CC0 Public Domain New research suggests that the negative effects of ozone holes on carbon uptake in the South Seas are reversible, but only when greenhouse gas emissions drop rapidly. The study, led by the University of East Anglia (UEA), shows that as ozone holes heal, the effects on marine carbon flow in the South Ocean decrease and greenhouse…

Saturday Quote: When the universe is young and cute. Plus: Southern Ocean cooling trends explained
By analyzing the high-resolution cosmic microwave background, researchers were able to see simple models of the universe and eliminate many competing options. Credit: ACT Collaboration. ESA/Planck Collaboration One of the strangest facts in computer science is that it is really difficult to generate true random numbers. Anyway, on a computer. I can do it well: 173, 401, 530. It’s true…

Climate change will intensify drought in central and southern Europe in 2022, study finds
Soil moisture deviation (in standard deviation units) for the summer of 2022 compared to a normal summer. The pink dots indicate where 2022 was the driest summer since 1960. Credit: UFZ The drought, which lasted until the summer of 2022, was particularly severe, causing soils to become significantly drier in many parts of Europe. Public debate about the causes has…

El Niño Southern Oscillation caused temperature rise in 2023, research shows
El Niño and La Niña are warm and cold periods of the natural climate pattern across the tropical Pacific Ocean, known as El Niño Southern Oscillation, or “ENSO” for short. This pattern changes erratically every two to seven years, causing predictable changes in ocean temperatures and disrupting normal wind and rain patterns across the tropics. These changes in the seasonal…
