   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".

   "Online Haters" Are Psychopaths, Recent Study Finds.   
   The Debrief, 6 Apr 2021   
   Recently published research finds that "online haters" or people who   
   post hateful comments on online forums and social media demonstrate   
   high levels of personality disorder traits associated with psychopathy.

   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.
