How green can Amazon hydropower be? Net carbon emission from the
largest hydropower plant in Amazonia

Science Advances via Carbon Brief

The Belo Monte dam - built on the Xingu River in Eastern Amazonia -
has caused a threefold increase in emissions of methane and carbon
dioxide (CO2), a new study finds. The authors measured methane
emissions at multiple sites on the Belo Monte reservoirs and
downstream of the dam, as well as methane and CO2 emissions from the
soils of islands and marginal areas of the Xingu River. They find that "reducing flooded areas and prioritising the power density of
hydropower plants" lowers the emissions of Amazonian reservoirs. The
study argues that, as dams increase emissions in the area, hydropower
expansion in Amazonia should be avoided, "regardless of the reservoir type".

Guest post: Emissions should fall `twice as fast' in case negative
emissions fail
Neil Grant and Dr Ajay Gambhir, Carbon Brief
The authors of a new paper published in Environmental Research Letters
explore the implications of uncertainty over whether large-scale
carbon dioxide removal (CDR) will become available as expected. Their
analysis concludes that emissions should be cut twice as fast during
the 2020s to keep warming "well-below" 2C while insuring against CDR
failure, even if the chances of non-delivery are small.

Climate change threatens age-old indigenous food systems, says UN
Fabio Teixeira, Reuters
A new report by the UN's Food and Agricultural Organization (FAO) says
that traditional food gathering techniques of indigenous communities
are under threat from accelerating climate change and economic
pressures, reports Reuters. The newswire adds: "Food systems used by
different indigenous peoples were found to be among the world's most sustainable in terms of efficiency, avoiding waste and adapting to the
seasons, said an FAO analysis...Because their diets rely mainly on
renewable resources found close to home, indigenous communities adjust
land use according to seasonality. Until recently, `waste' was an
unknown concept in their food systems, the report said. It cited as an
example Finland's Inari Sami people, whose diet depends heavily on
fish and reindeer meat."

Assessing biases and climate implications of the diurnal precipitation
cycle in climate models
Geophysical Research Letters
A new study finds that models in the sixth Coupled Model
Intercomparison Project (CMIP6) simulate rainfall over land 5.4 hours
too early, and simulate 0.81mm per day too little rainfall over the
ocean. The paper assesses the limitations in the way both CMIP6 and
CMIP5 models simulate 24-hour rainfall cycles by comparing the results
of model runs to satellite observations. The authors note that, while
CMIP6 models show "marginal improvements" compared to CMIP5 models,
both still "precipitate too early over both land and ocean".

Climate influence on the 2019 fires in Amazonia
Science of The Total Environment
Almost 40% of emissions from the 2019 fires in the Amazon were caused
by drier fuel, driven by low precipitation and relative humidity,
according to new research. The authors find that the dry conditions
are linked to "southerly wind anomalies over southern Amazonia",
driven by changing sea surface temperature patterns in the Indian
Ocean. The study "reveals how cold sea surface temperature anomalies
in the tropical eastern Pacific link the warm phase of the El
Niño-Southern Oscillation (ENSO) in the preceding Dec-Jan to
the dry-season fires in Amazonia", according to the paper. The authors
note that the findings of this study could improve extreme fire
prediction over Amazonia, as the dry conditions that lead to extreme
fires are becoming more common in the region.
