Forest degradation makes Amazon vulnerable to mega-fires

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.

President Trump is going all-in on pushing for a rapid, robust return to normal life, creating a visual, visceral contrast with Joe Biden and other Democrats who are more reticent to rip the masks off.

The state of play: Business friends have been urging Trump from the beginning to keep the lockdowns short. He's listening more and more.

Tech's long hot summer of antitrust

Google, Facebook and other tech giants face a summer of regulatory grilling as long-running investigations into potential anticompetitive practices likely come to a head.

The big picture: Probes into the power of Big Tech launched by federal and state authorities are turning a year old, and observers expect action in the form of formal lawsuits and potentially damning reports — even as the companies have become a lifeline for Americans during the pandemic lockdown.

Palantir CEO hits Silicon Valley "monoculture," may leave California

Palantir is "getting close" to a decision on whether to move the company out of California, CEO Alex Karp said in an interview for "Axios on HBO."

The state of play: "We haven't picked a place yet, but it's going to be closer to the East Coast than the West Coast. ... If I had to guess, I would guess something like Colorado."
