2017 SKS WEEKLY CLIMATE CHANGE & GLOBAL WARMING NEWS ROUNDUP #41

If climate change continues to worsen unchecked, and forest degradation continues unabated, then unstoppable Amazon mega-fires could be seen in this century; such fires would greatly increase the release of carbon into the atmosphere worsening climate change. Photo courtesy of IBAMA

Record Amazon fires stun scientists; sign of sick, degraded forests...

  • With the fire season still on-going, Brazil has seen 208,278 fires this year, putting 2017 on track to beat 2004’s record 270,295 fires. While drought (likely exacerbated by climate change) worsens the fires, experts say that nearly every blaze this year is human-caused.
  • The highest concentration of fires in the Amazon biome in September was in the São Félix do Xingu and Altamira regions. Fires in Pará state in September numbered 24,949, an astonishing six-fold increase compared with 3,944 recorded in the same month last year.
  • The Amazon areas seeing the most wildfires have also seen rapid change and development in recent years, with high levels of deforestation, and especially forest degradation, as loggers, cattle ranchers, agribusiness and dam builders move in.
  • Scientists warn of a dangerous synergy: forest degradation has turned the Amazon from carbon sink to carbon source; while globally, humanity’s carbon emissions are worsening drought and fires. Brazil’s rapid Amazon development deepens the problem. Researchers warn that mega-fires could be coming, unless trends are reversed.
