SCREAM featured on the cover of JAMES

First results from simulations performed with the Simple Cloud-Resolving E3SM Atmosphere Model (SCREAM) were recently published in JAMES (Caldwell et al, 2021) and an image from SCREAM was chosen for the journal’s November 21, 2020 issue cover. SCREAM is a new E3SM Atmosphere Model being developed from the ground up in order to support Graphics Processing Unit (GPU) architectures and to run efficiently at a global resolution of 3 km cell length.

Polynyas: Polar Physics Revealed through Visualization of the E3SM Global Climate Model

Abstract, Video Summary: pdf,  Video: mp4

The video highlights the role of polynyas in modulating earth’s mesoscale processes using high-resolution simulations from the Energy Exascale EarthSystem Model (E3SM).

Polynyas are openings within polar sea ice pack formed and sustained by atmospheric and oceanic processes. They occur in the Arctic ocean and the Southern ocean, lasting for many months, and act as a conduit for heat and water between the oceanic and atmospheric systems.

HPCwire: Energy Exascale Earth System Model Version 2 Promises Twice the Speed

The high performance computing magazine, HPCwire, featured a story on E3SM’s version 2 release, which included a key quote by scientist Chris Golaz from the LLNL and LANL press releases:  “From one version to another, Earth system models typically become better but also quite a bit slower, so both faster and better is significant.”

LLNL’s Science & Technology Review: Climate Change Comes Into Focus

Commentary by Dave Bader

The article describes, the newly released version 2 will be used to simulate aspects of Earth’s variability at weather-scale resolution and investigate decadal changes in climate that will critically impact the United States in coming years.

DOE Office of Science:  Climate Research at the Office of Science Roundtable Discussion

E3SM’s BGC Lead Scientist Kate Calvin, participated in a livestream roundtable discussion with Energy Secretary Jennifer Granholm, Deputy Director for Climate and Environment at the White House Office of Science and Technology Policy Jane Lubchenco, Associate Director for Operations for DOE’s Atmospheric Radiation Measurement (ARM) user facility Nicki Hickmon, and Senior Advisor in the Climate and Ecosystem Sciences Division (CESD) of Lawrence Berkeley National Laboratory’s Earth & Environmental Sciences Area Margaret Torn.

Polar warming is much faster than the mid-latitudes and tropics, and the warming over land is greater than over ocean, however it is unknown where more extreme heat events occur. New research shows more record-breaking temperatures and heat events will occur in the tropics rather than the poles.

World Economic Forum article:  What climate change will mean for the tropics

E3SM and University of Arizona researcher, Xubin Zeng’s recent paper on “Quantifying the Occurrence of Record Hot Years Through Normalized Warming Trends” was highlighted in a World Economic Forum article based on a University of Arizona press release titled “Record-Breaking Temperatures More Likely in Populated Tropics.”  The paper was also included in “AMS News You Can Use” and “AGU in the News.”

New York Times:  Emissions Cuts Could Drop the Impact of Melting Ice on Oceans by Half

Washington Post:  ‘Uncertainty is not our friend’: Scientists are still struggling to understand the sea level risks posed by Antarctica

UK’s Daily Mail: A successful Paris Climate Agreement could HALVE the ice we lose by 2100: Limiting global warming to 2.7°F would prevent the worst effects of sea level rise, scientists say

LANL’s Press Release:  Antarctica remains the wild card for sea-level rise estimates through 2100

LBNL/NERSC Press Release:  Limit global warming to 1.5°C and halve the land ice contribution to sea level this century

All news articles and press releases include a discussion of the Nature paper titled “Projected land ice contributions to twenty-first-century sea level rise” which was published May 5, 2021. Several E3SM and SciDAC ProSPect team members were co-authors on the Nature paper.

A helicopter flight over Greenland enabled UCI Earth system scientists to observe melt ponds. By gathering data from a network of weather instruments placed around the massive island, the researchers determined that surface melting of its ice sheet is coming mainly from the steady, day-to-day effect of wind- and solar-driven heat.  Image courtesy of Wenshan Wang (UCI).
