Why seasonal prediction skill changes over time 2 October 2019

Why seasonal prediction skill changes over time

The MAPP-funded study finds that ENSO, PDO, and other sources of abnormal sea surface temperatures serve as predictors for U.S. seasonal mean precipitation and that these sources change seasonally and decadally.

Monitoring time of emergence of climate change impacts on the oceans 23 September 2019

Monitoring time of emergence of climate change impacts on the oceans

A research team funded in part by the Climate Program Office has published a new paper describing the timelines during which we can expect to observe a variety of changes in the oceans due to climate change. The paper, published online August 19, 2019 in Nature Climate Change, is titled “Emergence of anthropogenic signals in the ocean carbon cycle.”

Alaska's Changing Environment: A new report on major observed climate changes

The Climate Program Office’s Alaska RISA team (Alaska Center for Climate Assessment and Policy), in partnership with the International Arctic Research Center and the University of Alaska, Fairbanks, has released a new report, Alaska’s Changing Environment, documenting recent observed profound changes in the environment related to extreme weather events and deviations from the historical climate.

Global climate model resolution significantly impacts modeled tropical cyclone response to increased CO2 and warming 26 August 2019

Global climate model resolution significantly impacts modeled tropical cyclone response to increased CO2 and warming

Researchers funded in part by the Climate Observations and Monitoring program, in collaboration with the Geophysical Fluid Dynamics Laboratory (GFDL), a NOAA facility at Princeton University, have published a new study that examines how projected climate features (global temperature, precipitation, and tropical cyclone activity) respond to increased CO2 conditions at varying resolution (25km vs. 50km vs. 200km). The article, “Tropical cyclone sensitivities to CO2 doubling: roles of atmospheric resolution, synoptic variability and background climate changes,” was published in the journal Climate Dynamics on August 13, 2019.
