Researchers have been modeling effects of the plant pathogen Phytophthora ramorum on coastal forests in California and Oregon since it arrived on the West Coast 3 decades ago.

Soil Carbon May Not Remain Bogged Down in a Warmer World
Carbon was lost from an experimentally warmed boreal peatland much faster than it took to accumulate. Elevated CO2 had little effect on stored carbon, requiring re-evaluation of model assumptions.
Experiments Reveal How Permafrost Carbon Becomes Carbon Dioxide
Field samples from Alaska show how sunlight and iron convert permafrost carbon to carbon dioxide. Climate models ignore this process.
Soil Remains Warmer and Drier After Long-term Warming Stops
Pausing a long-term soil warming experiment revealed that previously warmed plots remained both warmer and drier compared to plots which had not experienced previous soil warming.
Big Questions, Few Answers About What Happens Under Lake Ice
Scientists long eschewed studying lakes in winter, expecting that cold temperatures and ice cover limited activity below the surface. Recent findings to the contrary are changing limnologists’ views.
El Ciclo del Carbono en el Agujero Azul Más Profundo de la Tierra
Científicos encuentran nuevos extremos mientras investigan el ciclo del carbono en el agujero azul de Yongle.
A First Look at Elusive Deep-Ocean Carbon Molecules
A new analytical technique enables direct analysis of dissolved organic carbon molecules that store carbon in the ocean for thousands of years.
Visualizing the Deep Carbon Cycle
Geoscientists have created animations to help visualize different components of Earth’s carbon cycle.
Oceanic Changes Correlate with Methane Seepage
Changes in sea level and organic carbon burial may have affected seafloor methane seepage over the past 150 million years.
Eruption and Emissions Take Credit for Ocean Carbon Sink Changes
A new model explains why the ocean’s capacity to take up carbon was reduced on a decadal scale, by accounting for reduced pCO2 emissions and ocean state changes due to the eruption of Mt. Pinatubo.
