This year is on track to be the worst on record for forest fires in the Amazon, per the Brazilian government. The fires are doing the most damage in the areas of the forest already hit by human-caused forest degradation, Mongabay reports.

  • Distinct from deforestation, forest degradation is the process of felling just the valuable trees in a forest and leaving behind flammable tree limbs and debris, creating a ground zero for wildfires.
  • Why it matters: Climate change, deforestation and forest degradation are causing mega-fires that are devastating large swathes of the Amazon rainforest. Carbon emissions from the fires have the capacity to impact climate around the world.

The details:

  • The Amazon is currently experiencing a prolonged drought — lasting up to four months in some parts — which is contributing to the spread of the fires. And "the dry seasons in Brazil seem to be becoming drier and more frequent," scientist Luiz Aragão told Mongabay.
  • As of October 5, 208,278 hot spots have been seen in the region using thermal sensing. Fire brigades lack the manpower and resources to control them.
  • Forest degradation has transformed the Amazon from a carbon sink to a carbon source. Meanwhile, the uptick of carbon emissions around the world are contributing to bigger fires globally. The concurrent trends comprise a recipe for more mega-fires, scientists say.
  • "If Brazil is to have a chance at controlling the intensity of fires in the Amazon, it needs all countries — including the U.S. — to successfully reduce carbon emissions," Mongabay reports.

General Motors tries to revive incendiary lawsuit vs. Fiat Chrysler

General Motors is trying to revive an incendiary lawsuit against Fiat Chrysler Automobiles with explosive new allegations including bribes paid from secret offshore bank accounts and a union official acting as a double agent between the two automotive giants.

Why it matters: The extraordinary legal battle is occurring amid earth-shaking changes in the global auto industry that threaten to turn both litigants into dinosaurs if they aren't nimble enough to pivot to a future where transportation is a service, cars run on electrons and a robot handles the driving.

Cuomo says all New York schools can reopen for in-person learning

New York Gov. Andrew Cuomo announced Friday that all school districts across the state can choose to reopen for in-person learning because it has so far maintained low enough coronavirus transmission rates.

Why it matters: It’s another sign that the state, once the global epicenter of the pandemic, has — at least for now — successfully curbed the spread of the virus even as infections have surged elsewhere around the country.
