Tämän mukaan tulivuorenpurkausten vaikutukset voivat olla hyvinkin pitkiä:
“Our proxy product adds new, real-world data to estimate the responses on a global scale, which suggests these eruptions can cause much larger and prolonged wet and dry anomalies than we initially believed.”
“The trees, and the other natural climate archives were there to see these volcanic eruptions happen. It’s not a theoretical construct,” said coauthor Jason Smerdon, at Lamont-Doherty. “This was the first time we were able to use this new proxy product as an estimate of volcanic climate responses in the past, and the picture it paints has yielded surprises in terms of how large and persistent the hydroclimatic impacts of volcanism can be.”
A new study employs natural climate archives such as tree rings to better understand volcanoes' impacts on global rainfall patterns.
