CNN —At the end of July, Colorado became the latest US state to battle the spread of wildfires. There are satellites, which orbit the exosphere, between 375 miles (600 kilometers) and 6,200 miles (10,000 kilometers) above Earth, and also provide imagery, but often of a much lower quality than one of Urban Sky’s balloons. Another upside of Urban Sky’s balloons is cost, he says. It wants to create a model for both selling the balloons outright and operating the balloons itself while selling data as a service. “As wildfires continue to increase in frequency, intensity, magnitude and duration, such technology for managing wildfires could not come soon enough,” says Fisher.

CNN —Some leaves in tropical forests from South America to South East Asia are getting so hot they may no longer be able to photosynthesize, with big potential consequences for the world’s forests, according to a new study. They found that average forest canopy temperatures peaked at 34 degrees Celsius (93 Fahrenheit) but some exceeded 40 degrees Celsius (104 Fahrenheit). This level of warming is not expected under current climate policies, which are estimated to bring 2.7 degrees Celsius of warming above pre-industrial levels. While these figures may seem small, the risk is significant given how critical tropical trees are for life, the climate system and the planet. But, he added, there are more immediate concerns for tropical forests, including deforestation, wildfires and droughts.
