Hotter temperatures extend growing season for peatland plants

SPRUCE experimental site

A futuristic experiment simulating warmer environmental conditions has shown that peatland vegetation responds to higher temperatures with an earlier and longer growth period. Researchers used direct observation and digital repeat photography to measure plant greenness over three years at the Spruce and Peatland Responses Under Changing Environments study, a unique ecosystem-scale experiment operated by DOE’s Oak Ridge National Laboratory.

Plants- Surviving the Heat

A study by Oak Ridge National Laboratory detailed the response and recovery of certain tree species after short-term, extreme weather events such as heat waves. Scientists exposed sets of four different saplings to dramatic temperature swings that peaked above 120 F, or around 50 C, in a climate-controlled test chamber.

Scientists project a drier Amazon and wetter Indonesia in the future

Climate models predict that an increase in greenhouse gases will dry out the Amazon rainforest in the future while causing wetter conditions in the woodlands of Africa and Indonesia.

New exascale earth modeling system for energy


A new earth modeling system will use advanced computers and have weather scale resolution to simulate aspects of Earth’s variability and anticipate decadal changes that will critically impact the United States’ energy sector.

Climate study predicts declining marine biological productivity

A national team of Earth system modelers analyzed simulations through the year 2300 and found that increasing global temperatures could drive declines in marine biological productivity, decreasing fishery output by 20% globally and 60% in the North Atlantic.
