7.5 Extreme wildfire spread accelerates forest ecosystem change across western and boreal North America

Wildfires across western and boreal North America are accelerating in frequency, size, and severity. Canada's 2023 season burned 16.5 million hectares—more than double the previous record—while the 2024 Jasper wildfire caused $1.23 billion in insured damages. Climate change has become the dominant driver of increased wildfire risk since 2000.

  • Canada 2023: 16.5 million hectares burned, over 2x previous record
  • 2025 Canada: 8.3+ million hectares, second worst on record
  • 2024 Jasper wildfire: $1.23 billion insured damages
  • Fire seasons starting earlier and lasting longer
  • Human-caused climate change dominant risk factor since ~2000

7 Trump Administration Weakens Endangered Species Habitat Protections

The president of the United States' administration finalized a rule on July 10, 2026, removing habitat destruction from the definition of 'harm' under the Endangered Species Act, effective September 14, 2026. This weakens protections for endangered species by allowing developers to destroy habitat without legal consequence, though direct killing and injury remain prohibited.

  • Habitat destruction no longer counts as illegal 'take' under the law
  • Rule takes effect September 14, 2026
  • Designated critical habitat remains protected, but much habitat outside designated areas loses protection
  • Change could facilitate farming, drilling, mining, logging, and development in endangered species habitats

Space Exploration

7 First evaluation of wearable radiation protection for deep space exploration on Artemis I

NASA's Artemis I mission tested the AstroRad vest, a 26-kilogram wearable radiation protection garment, on model torsos inside the Orion spacecraft. The vest demonstrated reduced radiation exposure compared to unprotected models, advancing technology for long-duration deep-space missions.

  • AstroRad vest: 26 kilograms
  • Tested aboard Artemis I in 2022
  • Demonstrated radiation protection vs. unprotected model
  • Developed by StemRad with Israel Space Agency and Lockheed Martin support
