Reliably detecting wildfires early will probably require a combination of different technologies working together, experts say.
“The odds of a single technology coming along and solving the entire problem are not zero, but they’re not great — at least not in the near future,” said Cristina Davis, a professor at UC Davis.
Satellites, for example, can scan vast swaths of terrain and quickly produce images that can be monitored by AI to identify potential blazes. That has enabled fires to be detected “within the first 10, 20, 30 minutes of ignition,” Pavolonis said. But satellites can have limits to their coverage and might not be able to identify very small fires, Mohapatra said. Cameras, which are often installed in towers, can more closely monitor conditions on the ground, but setting up these networks is typically an “immense initial cost,” she added.
And sensors, though often cheaper, can be hard to place in certain types of terrain, such as rocky areas at high altitudes, which typically aren’t easily accessible. Other locations might be inaccessible because they are on protected lands, Mohapatra said.So, ideally, she said, there should be “multiple layers of monitoring that are fail-safe.

A Game Plan for Funding Carbon OffsetsThe most common types of carbon offsets are nature-based offsets such as forests. Unfortunately, while emissions remain in the atmosphere around 1,000 years, possibly longer, a tree can only remove carbon for its lifespan of 10o or so years, which means a forest planted as a carbon offset must be maintained with trees replanted at least ten times to match the emission it is offsetting. Most businesses will be reluctant to tie up capital in this way, but such projects can be (and have been) financed by perpetual bonds, which represent attractive investments for investors such as university endowments that have very long liability streams extending far into the future. The use of financial instruments such as perpetual bonds can make considerable quantities of capital available to offset producers, spurring the production and the creation of spot markets in offsets that can definitively and reliably be offset against emissions.
